Navy drone flies alongside fighter jets


 
The movement of jets aboard an aircraft carrier flight deck is often compared to a ballet, with sailors in multicolored shirts guiding fighter pilots and their jets in a tightly choreographed dance.

 So what happens if you add a robot to the human performers?


 The Navy attempted to answer that question Sunday aboard the aircraft carrier Theodore Roosevelt, where, for the first time, the service's prototype of an unmanned stealth plane, the X-47B, took off and landed on a carrier flight deck alongside traditional fighter jets.

NAVSEA: North Dakota Attack Boat Investigation Complete

Naval Sea Systems Command (NAVSEA) has concluded an investigation into questionable third party components of its latest Virginia-class attack boat — North Dakota (SSN-784) — clearing the way for the submarine to commission in late October, NAVSEA told USNI News on Thursday.
 
“To date, all necessary inboard and outboard components have been inspected and all required repairs have been completed,” read a statement provided to USNI News.
 
NAVSEA inspected 58 components — mostly in the bow and stern sections — of the $2.6 billion attack boat and conducted an unspecified number of repairs, according to the statement.
 
“These components included stern planes and rudder rams, retractable bow plane cylinders, hydraulic accumulators, high pressure air charging manifolds, torpedo tube interlocks and shaft/link assemblies, weapons shipping and handling mechanisms, and other miscellaneous parts,” NAVSEA statement.

“The submarine was certified for sea trials and is tracking towards the Aug. 31 contractual delivery date.”
 
NAVSEA said other Block III Virginias would also be inspected. Neither the Navy nor Virginia-class prime contractor — General Dynamics Electric Boat —would identify the vendor to USNI News.
 
Huntington Ingalls Industries (HII) — responsible for most construction of the bow and stern sections — referred comment on the program to NAVSEA and Electric Boat.
 
The commissioning delay and investigation are rare missteps in what is arguably the Navy’s best-run shipbuilding program in decades.
 
North Dakota is the first of the Block III boats. The revised design feature 40 percent of the bow retooled to accommodate a new water-backed Large Aperture Bow (LAB) sonar array and the addition of two Multiple All Up Round Canisters that can each hold six Tomahawk Land Attack Missiles (TLAM).
 
The redesign was led by Electric Boat and constructed by Newport News as part of the teaming agreement between the two yards for the Virginia-class construction.
 
Despite the delay, North Dakota will most likely still deliver ahead of its 66-month construction schedule.
 
The final Block II boat— USS Minnesota (SSN-783) — delivered 11 months early.
NAVSEA’s full Thursday statement to USNI News follows:
 
The commissioning of PCU NORTH DAKOTA (SSN 784) was postponed from May to address material issues with vendor-assembled and delivered components.
 
To date, all necessary inboard and outboard components have been inspected and all required repairs have been completed.
 
There were a total of 58 components investigated aboard PCU NORTH DAKOTA (SSN 784).
These components included stern planes and rudder rams, retractable bow plane cylinders, hydraulic accumulators, high pressure air charging manifolds, torpedo tube interlocks and shaft/link assemblies, weapons shipping and handling mechanisms, and other miscellaneous parts.
 
The submarine was certified for sea trials and is tracking towards the August 31 contractual delivery date. The commissioning is scheduled for October 25. All other Block III submarines are being inspected and any issues found will be adjudicated.

The USS Enterprise Is Being Shut Down

It's the beginning of the end for the USS Enterprise. After 50 years of service, the world's first nuclear-powered aircraft carrier is going dark at the same shipyard where it was first built.
 
Around 600 sailors and 1,200 employees at the Newport News shipyard in Virginia have been tasked with completing the "inactivation."
 
The Navy has never permanently shut down a nuclear-powered aircraft carrier. A big part of the job — removing spent fuel from the ship's nuclear reactors — is nothing new. Newport News has accomplished several mid-life carrier overhauls, which involve defueling followed by refueling. That's part of getting the ship back in the fight, as the Navy likes to put it.
 
But the Enterprise has no more fighting days left, and shipyard workers now face a sad reality: The ship is literally going dark before their eyes.
 
"We've got probably half the ship or more that is uninhabited," said Dave Long, program director. "It's dark — no electricity, no ventilation. And we've actually sectioned it off with certain barriers and locks, very safely, so people can't get lost."
 
Long tells the story about a small group of Newport News workers who would hop on a plane to make repair calls to a different part of the globe. That's the kind of loyalty the Enterprise inspires, he said.
 
Today, some employees simply want to walk onto the ship one last time. Long is already fielding requests from employees to "ride" the ship for a few hundred yards when, in January, it will transfer from Pier 2 to Dry Dock 11.
 
The Enterprise will remain in Newport News until 2016. Eventually, it will be towed from Hampton Roads around the tip of South America to Puget Sound Naval Shipyard and Intermediate Maintenance Facility in Bremerton, Wash.
 
There it will be dismantled and recycled.
 
"If you didn't serve on Enterprise, you really haven't lived," said Rear Admiral Thomas More.
 
Trivia Note: The USS Enterprise was on deployment during the filming of Star Trek IV: The Voyage Home, so the USS Ranger served as the stand-in "nuclear wessel

USN - Navy Accepts Delivery of Mobile Landing Platform


The Navy accepted delivery of the first Mobile Landing Platform, USNS Montford Point (MLP 1), from General Dynamics-NASSCO, May 14, in San Diego, Calif.

The Mobile Landing Platform is a new class of ship and highly flexible platform that will provide capability for large-scale logistics movements such as the transfer of light and heavy vehicles and equipment from sea to shore.

"MLP-1 has gone from concept to delivery in under five years, a remarkable feat reflecting the diligent work of the Navy and shipbuilding team from design through testing and trials," said Capt. Henry Stevens, PEO Ships' program manager for strategic and theater sealift. "With its open, reconfigurable mission deck, USNS Montford Point will deliver innovation and exceptional flexibility to future Fleet operations."

Delivery of Montford Point represents the official transfer of the ship from the shipbuilder to the Navy and is a major milestone in the ship's transition to operational status. Delivery follows the successful completion of Acceptance Trials, evaluating the ship's major systems and equipment.

Named in honor of the 20,000 African-American Marine Corps recruits trained at Montford Point Camp, N.C., MLP-1 is a modular, adaptable platform that may be used across a broad range of military operations supporting multiple operational phases. Acting as a mobile seabase, MLP will be part of the critical access infrastructure that supports the deployment of forces and supplies to provide prepositioned equipment and supplies with flexible distribution.
 
The 83,000 ton, 785-foot ship will leverage float-on/float-off technology, allowing Montford Point to partially submerge, facilitating easy movement of cargo and craft. Additionally, the ship's size allows for 25,000 square feet of vehicle and equipment stowage space and 380,000 gallons of JP-5 fuel storage. MLP-1 has a maximum speed of 15 knots and range of 9500 nautical miles.

Following delivery, the ship will undergo test and trials period to install and incorporate the ship's Core Capabilities Set (CCS) in Portland, Ore. The CCS includes modules that support a vehicle staging area, sideport ramp, large mooring fenders and up to three landing craft air cushioned (LCAC) vessel lanes. With this set of capabilities, MLP-1 is able to easily transfer personnel and vehicles from other vessels such as the large, medium-speed, roll-on/roll-off ships (LMSRs) onto LCAC vehicles and transport them ashore.

The ship is owned by U.S. Navy's Military Sealift Command (MSC) and operated by a 34-person civilian-mariner crew under contract to MSC. The Navy plans to integrate an MLP into each of MSC's Maritime Prepositioning Ship Squadrons. These ships, coupled with a maritime prepositioning force (MPF), auxiliary dry cargo/ammunition ship (T-AKE) and legacy platforms, provide a first step in crafting a sea-based capability and illuminating future seabasing requirements.

MSC operates approximately 110 non-combatant, civilian-crewed ships that replenish U.S. Navy ships, conduct specialized missions, strategically preposition combat cargo at sea around the world and move military cargo and supplies used by deployed U.S. forces and coalition partners.

As one of the Defense Department's largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and special warfare craft. Delivering high-quality war fighting assets - while balancing affordability and capability - is key to supporting the Navy's Maritime Strategy.

USS Reuben James making final return to Hawaii Read more: http://www.kitv.com/news/hawaii/uss-reuben-james-making-final-return-to-hawaii/-/8905354/19978796/-/lx29pd/-/index.html#ixzz2S9f36lr4

The Oliver Hazard Perry-class guided missile frigate USS Reuben James will return to its homeport in Hawaii from a deployment to the Western Pacific on May 3.

During the ship's seven-month deployment, the crew of Reuben James participated in a series of bilateral maritime exercises or Cooperative Afloat Readiness and Training while conducting at-sea security scenarios, helicopter operations, a search and rescue practical and surface gunfire drills in the Seventh Fleet Area of Responsibility.

"First and foremost, thank you to the crew of USS Reuben James for your outstanding performance," said Reuben James Commanding Officer Cmdr. Daniel Valascho.  "Our motto is 'Back With A Vengeance,' but now we're back with a sense of satisfaction, knowing we did our part operating forward, strengthening partnerships and protecting freedom."

Having completed her final deployment Reuben James will be decommissioned this August after 27 years of service to the fleet.

"They maintained readiness, showed their pride and professionalism and always looked out for each other on and off duty," said Command Master Chief CMDMC(SW) Johannes J. Gonzalez. "I'm very proud of them all and I cannot think of a better crew to represent Reuben James on her final deployment."

During the ship's history it has completed deployments to the Arabian Gulf in support of Operations Enduring and Iraqi Freedom, to the Eastern Pacific in support of counter-drug operations and it appeared in the 1990 motion picture The Hunt For Red October.

"I also want to thank all the families and friends who stood by us and prepared a native Hawaiian welcome for the entire crew. It will be great to see you all pierside," added Valascho.

Guided-missile frigates are multi-mission surface combatants, capable of Under-Sea Warfare and Surface Warfare missions. Reuben James is assigned to Commander, Destroyer Squadron 31 under Commander, Naval Surface Group Middle Pacific, in Hawaii.

U.S. Third Fleet leads naval forces in the Eastern Pacific from the West Coast of North America to the international date line. Joint, interagency and international relationships strengthen Third Fleet's ability to respond to crises and protect the collective maritime interests of the U.S. and its allies and partners.

Stennis Strike Group Arrives in Hawaii

The John C. Stennis Carrier Strike Group (JCSCSG) made its first stop in the U.S. at Joint Base Pearl Harbor-Hickam April 21 following an eight-month deployment to the 5th and 7th fleet areas of responsibility (AOR).

While deployed, JCSCSG flew more than 11,500 sorties totaling 27,000 flight hours, and conducted community relations and service projects during port visits to Thailand, Malaysia, the Kingdom of Bahrain, the United Arab Emirates, and the Republic of Singapore.

"We are excited to be back in the U.S. after a very successful deployment," said Rear Adm. Mike Shoemaker. "The strike group Sailors here did a fantastic job in every mission area. Through their efforts, we were able to provide extensive support to the coalition effort in Operation Enduring Freedom and to enhance our maritime relationships with regional partners throughout the 5th and 7th fleet operating areas."

Hawaii also marks the homecoming for many Stennis Strike Group Sailors, as they were able to visit with friends and family.

"This visit will be a nice reunion for my family and I to pick up where we all last left off and meet the new additions to our family," said Cmdr. Chad Lee, from Kailua, Oahu. "This visit is special for all of us because we will all be visiting my 95-year-old great grandmother."

The JCSCSG, consisting of Stennis, Carrier Air Wing (CVW) 9, Destroyer Squadron (DESRON) 21, and guided-missile cruiser USS Mobile Bay (CG 53), is returning from an eight month deployment to the U.S. 5th and 7th AORs.

Submarine USS Thresher sinking 50 years ago led to safety changes



The first sign of trouble for the USS Thresher was a garbled message about a "minor difficulty" after the nuclear-powered submarine descended to about 1,000 feet on what was supposed to be a routine test dive off Cape Cod.

Minutes later, the crew of a rescue ship made out the ominous words "exceeding test depth" and listened as the sub disintegrated under the crushing pressure of the sea. Just like that, the Thresher was gone, along with 129 men.

Fifty years ago, the deadliest submarine disaster in U.S. history delivered a blow to national pride during the Cold War and became the impetus for safety improvements. To this day, some designers and maintenance personnel listen to an audio recording of a submarine disintegrating to underscore the importance of safety.

"We can never, ever let that happen again," said Vice Adm. Kevin McCoy, an engineer and former submariner who now serves as commander of the Naval Sea Systems Command in Washington, D.C.
This weekend, hundreds who lost loved ones when the Thresher sank will gather at memorial events in Portsmouth, N.H., and Kittery, Maine.

Built at Portsmouth Naval Shipyard in Kittery, and based in Groton, Conn., the first-in-class Thresher was the world's most advanced fast attack submarine when it was commissioned in 1961.

Featuring a cigar-shaped hull and nuclear propulsion, the 278-foot-long submarine could travel underwater for unlimited distances. It could dive deeper than earlier submarines, enduring pressure at unforgiving depths. It was designed to be quieter, to avoid detection.

On April 10, 1963, the submarine already had undergone initial sea trials and was back in the ocean about 220 miles off Cape Cod, Mass., for deep-dive testing. Some submariners are baffled by the initial message about a minor difficulty because it's believed a brazed joint on an interior pipe had burst — a problem anything but minor.

The Navy believes sea water sprayed onto an electrical panel, shorting it out and causing an emergency shutdown of the nuclear reactor.

The submarine alerted the USS Skylark, a rescue ship trailing it, that it was attempting to surface by emptying its ballast tanks. But that system failed, and the sub descended below crush depth.
Understanding their dire situation, Navy crew members and civilian technicians would have scrambled to close valves to try to stem the flooding, struggled with a ballast system disabled by ice, and worked to restore propulsion by restarting the reactor, a 20-minute process.

Their deaths would have been instant because of the force of the violent implosion. The sub's remnants came to a rest on the ocean floor at a depth of 8,500 feet.

There was nothing the divers on the Skylark could do.

"It's one of those times when there's silence," recalled Danny Miller, one of the Skylark divers, now 70 and living in Farmington, Mo. "You don't know what to say. You don't know how to feel. You just know something tragic has happened."

The Thresher wreckage covers a mile of ocean floor, according to University of Rhode Island oceanographer Robert Ballard, who used his 1985 discovery of RMS Titanic as a Cold War cover for the fact that he had surveyed the Thresher on the same mission.

"It was like someone put the submarine in a shredding machine," Ballard said in a recent interview. "It was breathtaking. There were only a couple of parts that looked like a submarine."
Word of the disaster spread quickly.

Paul O'Connor, now a union president at Portsmouth Naval Shipyard, remembers seeing the bulletin on TV. He was 6. Barbara Currier, whose husband, Paul, was a civilian worker on the Thresher, was shopping with her daughters when she heard the news on the radio in a store.

What followed was a blur of activity for families. Navy officers in dress whites showed up on doorsteps. Friends and neighbors brought food.

After the submarine was declared sunk, President John F. Kennedy ordered the nation's flags lowered to half-staff. International leaders sent condolences.

"The men, they were heroes. Most of them were doing what they wanted to do for their country to keep the country safe," said Currier, 86, who never remarried and still lives in the same house in Exeter, N.H. "They were pushing things to the limit."

For the families, the silver lining is that subs are now safer. The Navy accelerated safety improvements and created a program called "SUBSAFE," an extensive series of design modifications, training and other improvements.

People involved in the SUBSAFE program are required to watch a documentary about the Thresher that ends with an actual underwater recording featuring the eerie sounds of metal creaking and bending as a U.S. Navy submarine breaks apart with the loss of all hands.

"Every job we do, we need to have in the back of our minds that we have the lives of the sailors in our hands. It's that critical and it's that literal," said O'Connor, president of the Metal Trades Council.
Hundreds of family and friends of the Thresher's crew, along with sailors who previously served on the submarine, will gather Saturday for a memorial service in Portsmouth, N.H. A day later, neighboring Kittery will dedicate a flagpole that stretches 129 feet high in remembrance of the number of lives lost.

Because of their tender ages, and the lack of a body or proper grave site, children like Vivian Lindstrom, who lost her father, Samuel Dabruzzi, a Navy electronics technician, were unable to grieve properly.

Thanks to the reunions, they at least know they're not alone, said Lindstrom, of Glenwood City, Wis.
"We've experienced the same things, felt the same things," she said. "We feel like family. We call ourselves the Thresher family."

U.S. Navy Take Notice: China is Becoming a World-Class Military Shipbuilder




China’s military shipyards now are surpassing Western European, Japanese, and Korean military shipbuilders in terms of both the types and numbers of ships they can build. If Beijing prioritizes progress, China’s military shipbuilding technical capabilities can likely become as good as Russia’s are now by 2020 and will near current U.S. shipbuilding technical proficiency levels by 2030. China is now mass producing at least six classes of modern diesel-electric submarines and surface warships, including the new Type 052C “Luyang II” and Type 052D “Luyang III” destroyers now in series production.

Eight key themes, listed sequentially below, characterize China’s rise as a world-class military shipbuilder. For reference, the companies building the warships are China State Shipbuilding Corporation (“CSSC”) and China Shipbuilding Industry Corporation (“CSIC”).

1.China’s warship buildout thus far supports modernization and replacement, not rapid expansion

Over the past six years, China’s overall fleet of frontline combatants has expanded, but slowly, growing from 172 ships in 2005 to an estimated 221 vessels in 2012. However, the fleet has improved substantially in qualitative terms as newer ships and subs replace older ones. For instance, as Type 052 C/D Luyang-series destroyers, Type 054A Jiangkai II-series frigates, and Type 041 Yuan diesel-electric submarines have come into the fleet, they are allowing the People’s Liberation Army Navy (PLAN) to steadily retire obsolete platforms like Luda destroyers and Ming submarines.

2. Chinese military shipbuilders are catching up to Russian and U.S. Yards

China’s large state-backed military shipbuilders are approaching their Russian and U.S. peers in terms of the number of warships built. China’s large submarine and surface warship buildout will, in a decade, likely have it become second only to the U.S. in terms of total warships produced since 1990. More importantly, the ramp-up of China’s construction of large warships in recent years will mean the PLA Navy will likely be taking delivery of larger numbers of modern surface combatants and submarines annually than the U.S. Navy.

Measured in terms of warships commissioned since 1990, China is now number three globally and is rapidly gaining on Russia, the number two country. Most of Russia’s post-1990 military ship deliveries simply reflected yards “finishing up” Soviet-era projects.

Chinese yards, in contrast, have come on strong over the past decade, with a big push in submarine construction that began in 2002-03 and a strong pipeline of surface warship deliveries that continues to gain steam to this very day. Chinese military shipyards—in particular the Changxing Island and Hudong Zhonghua yards near Shanghai—are humming with activity, and over the next 2-3 years, China is likely to commission enough large warships to put it second only to the U.S. in terms of large warships built and delivered since 1990.

3. China’s military shipbuilders are using modular mass production techniques

CSSC’s Jiangnan Shipyard is using modular construction methods to build Type 052-series destroyers. Modular construction involves building the ship in “blocks.” This maximizes a shipyard’s productive potential and also provides greater latitude for modifying designs and customizing ships. Modular construction also gives yards the flexibility to either build centers of expertise within the yard or outsource the production of certain components and then import them to the yard for final assembly.
CSSC’s Hudong Zhonghua shipyard also appears to be using modular construction techniques for the Type 071 LPD. The yard has now constructed four of the vessels, two of which are in service and two of which are in the trial/outfitting stage. They have also been able to fabricate the Type 071 hulls faster, with a time gap of nearly four years between the first and second vessels, but only 10 months between vessels two and three, and four months between vessels three and four.

1. China’s military shipyards appear to be sharing design and production information across company lines

Historically, CSIC built all Chinese submarines, but the current production run of Type 041 Yuan-class advanced diesel electric subs has seen at least two boats being built in CSSC’s Jiangnan yard. This suggests submarine construction expertise is growing outside of CSIC. However, there are no indications thus far that CSSC is doing submarine design work, which could mean that Beijing is making the companies and their design institutes share submarine design and construction information. Likewise, the new Type 056 corvette is being built in both CSSC and CSIC shipyards, suggesting that a standardized design and production approach is being shared by both companies.

5. China’s military shipbuilders will be able to indigenously build aircraft carriers

China’s first aircraft carrier, Liaoning which entered service on  September 25th of this year, started as an empty hull and gave CSIC valuable experience in effectively creating an aircraft carrier from the keel up. China has a total of seven shipyards with sufficiently large berths to assemble a carrier hull (three hundred meters or more), and the yards are basically equally dispersed between CSSC and CSIC. These yards are located in Dalian (CSIC), Qingdao (CSIC), Huludao (CSIC), Shanghai (CSSC), and Guangzhou (CSSC).

CSIC Bohai Shipbuilding Heavy Industry complex near Huludao (where China builds its nuclear submarines) is a top candidate due to its large, covered building sheds where carrier parts could be fabricated in modular fashion and out of the view of satellite surveillance. The company says it has the “largest indoor seven-step” ship construction facilities in China. This facility, together with CSSC’s large new Changxing Island yard, and CSIC’s Dalian yard—which fitted out the carrier Liaoning that just entered PLAN service—are the three leading candidates to build China’s indigenous carriers.

6. China will retain a military shipbuilding cost advantage

We project that for at least the next five years, Chinese shipbuilders will have a substantial labor cost advantage over their counterparts in South Korea, Japan, and the U.S. CSSC’s Jiangnan shipyard can likely deliver a Type 052C destroyer for 24% less than it costs Korea’s Hyundai heavy Industries to produce a KDX-III destroyer. Likewise, according to disclosures in the July 2011 issue of Shipborne Weapons, Wuchang shipyard can produce a late model diesel electric sub such as the Type 041 for roughly 47% less than it would cost South Korea’s DSME to make a Type 209 submarine. The lower labor cost in China likely serves as a core driver. This may help explain the larger Chinese cost advantage in building submarines, since advanced submarines can require substantially larger number of man-hours to build than surface ships do.

7. China’s neighbors feel increasingly compelled to augment their naval forces in response to Chinese warship production

South Korea has decided to expand its procurement of advanced diesel-electric submarines to include nine KSS-III 3,000-ton submarines by 2020 and nine 1,800-ton subs by 2018. This acquisition will basically double the size of the country’s current sub force and substantially enhance its capabilities, since the biggest boats in the fleet are currently 1,800-ton vessels. South Korea has also elected to double its Aegis destroyer purchases over the next decade.

Similarly, Vietnam’s maritime friction with China and fear of the PLAN’s growing power is making Hanoi into one of the Russian defense industry’s star customers. Vietnam has ordered six Kilo-class diesel submarines from Russia and is likely to take delivery of its first Kilo by the end of 2012. Hanoi is also adding advanced Russian anti-ship missiles and stealthy Gepard-class missile armed patrol boats to its naval force.

8. China now has the potential to become a significant exporter of diesel submarines and smaller surface warships

China’s shipbuilders are becoming increasingly competitive in terms of the ratio of cost to combat power they can deliver. For instance, the July 2011 issue of Shipborne Weapons reports that China will supply 6 potentially Air-Independent Propulsion (AIP)-equipped submarines to Pakistan for as little as 1/3 the unit price at which European shipyards would be able to supply comparable boats.

With the advent of the Type 041 Yuan-class diesel sub and Type 056 corvette, China now has two platforms for which it is already capable of series production and for which the unit costs are likely to drop significantly in coming years. The export version of Russia’s Steregushiy-class corvette, called Tigr, currently stands at around U.S. $150 million per vessel. As China’s Type 056 production run continues to expand, it would not be a surprise to eventually see the PLAN’s unit cost end up in the U.S. $110-120 million per vessel cost range, which would make the Type 056 a serious export competitor to the Tigr and other smaller Russian warships.

Conclusion

China’s naval shipbuilding industry has advanced to the point that it can series produce modern diesel submarines, landing platform docks (LPDs), destroyers, frigates, corvettes, and fast attack craft, albeit with some imported components for a number of key systems. The ongoing series production of Type 041 SSKs, Type 071 LPDs, Type 052 destroyers, and Type 056 corvettes strongly suggests that China’s military shipbuilders have rapidly assimilated commercial innovations such as modular construction.

Chinese naval shipbuilding faces several challenges moving forward. Most notably,

Six major questions remain:
1. Does Beijing have the political will to continue devoting substantial and growing resources to naval modernization?

2. Can China achieve requisite technical advances in weapons systems, propulsion, and military electronics?

3. Can China master the technologies needed to build nuclear submarines capable of surviving in a conflict with U.S. and Russian boats?

4. Can it build an aircraft carrier with catapults that would allow it to maximize the strike and air combat capabilities of the J-15 fighter it is likely to carry?

5. Will the Chinese leadership be willing to invest political and financial capital in establishing intensive and realistic training for the PLAN and provide diplomatic support for establishment of sustained access to facilities in key areas such as the Indian Ocean region?

6. Will continued weakness in the global ship market prompt Beijing to capitalize on the availability of shipyard space to further increase the pace of military shipbuilding?
China’s military shipbuilders are showing that they can meet Beijing’s current call for warships and could produce more if given the mandate and the resources.

The U.S. strategic rebalancing toward the Asia-Pacific will need more than rhetoric if it is to remain credible in the face of China’s potential to rapidly produce modern warships.

The Pentagon should consider adjusting the U.S. Navy’s ship acquisition programs in response. As Chinese warships become better, the numbers ratio between the PLAN and U.S. Navy combatants will become increasingly important.  Given that shipbuilding is an industry where lead times can be many years, now is the time for Washington to begin responding to China’s warship production improvements and prepare strategically for further naval advances that Beijing is likely to unveil over the next 2-3 years.

U.S. Navy adopts specs for new sub



Key specifications for a submarine to replace U.S. Navy's Ohio class submarines have been formally adopted.

The Ohio Replacement First Article Quad Pack Ship Specification document, a major milestone in eventual construction of ships, was signed last week in Washington by Rear Adm. Thomas J. Eccles, chief engineer and deputy commander Naval Systems Engineering Directorate, Naval Sea Systems Command, and Capt. William J. Brougham, Ohio Replacement program manager.

The new vessels are also part of Britain's Successor ballistic missile submarine program.

"This document marks significant forward progress for both the U.S. and U.K. future strategic submarine deterrent programs," Brougham said. "It is a direct result of the engineering rigor and professionalism of government and industry partners on both shores of the Atlantic."

The U.S. Navy said the specifications are critical for the design and construction of the common missile compartment -- including missile tubes and associated equipment.

"The Ohio Replacement Program will serve as the backbone of our nation's nuclear deterrence into the 2080s," said Eccles. "It is vital that we perform the rigorous engineering, research, and design work now so that we can ensure that the platform is able to address and best the threats of future highly complex national security environments."

The Navy plans to replace its fleet of 14 Ohio-class SSBNs with 12 new submarines. The first Ohio Replacement is to begin construction in fiscal year 2021.

US Warship Leaves Builder's Yard for Commissioning

The Navy's littoral combat ship, the future USS Fort Worth sails from Marinette Marine's shipyard for Galveston, Texas.

Fort Worth is the third littoral combat ship delivered to the Navy, and the second LCS of the steel, semi-planing, mono-hull Freedom variant is scheduled to be commissioned on Sept. 22, 2012.

Prior to sail-away, the Navy's Board of Inspection and Survey (INSURV) conducted acceptance trials aboard Forth Worth. INSURV found the ship to be "highly capable, well-built and inspection ready," and recommended the vessel be accepted.



A number of design changes have been incorporated in LCS 3 based on lessons learned from the first ship of class, USS Freedom (LCS 1). These changes are now part of the baseline design and will be incorporated into future ships of the class prior to construction. 



The littoral combat ship is a high-speed, agile, shallow-draft, focused-mission surface combatant designed for operation in near-shore environments yet fully capable of open-ocean operation.

Fort Worth, a high-speed steel mono-hull ship, is designed to defeat asymmetric "anti-access" threats such as mines, quiet diesel submarines and fast surface craft.

The 387-foot Fort Worth will be outfitted with reconfigurable payloads, called mission packages, which can be changed over quickly, and focus on three mission areas: mine countermeasures, surface warfare and anti-submarine warfare. 


Construction begins on 11th LPD for US Navy

Work on the US Navy's 11th and final San Antonio-class amphibious transport dock ship LPD 27 has started at Huntington Ingalls Industries' (HII) shipbuilding division.

Ingalls LPD programme vice president Doug Lounsberry said: "Lessons learned and production improvements from all the previous LPDs have been incorporated into LPD 26 and are being rolled over into LPD 27."

Under the $1.5bn contract awarded recently to HII for detail design and construction of the LPD 27, fabrication work will be followed by keel laying currently scheduled to take place in the second quarter of 2013.

With a displacement capacity of 24,900t, the 684ft-long, 105ft-wide San Antonio-class ship can accommodate 800 troops and provide combat support for the US Navy and US Marine Corps.
“Lessons learned and production improvements from all the previous LPDs have been incorporated into LPD 26 and are being rolled over into LPD 27.”

The frigate will be able to carry two Sikorsky CH-53E Sea Stallion helicopters, six Bell AH-1W Super Cobra helicopters, four Boeing Vertol CH-46 Sea Knight helicopters or two Boeing Bell MV-22 Osprey tilt rotor aircraft on its flight deck.

In addition, the vessel will feature enhanced fighting capabilities, such as advanced command-and-control suite, and increased lift-capabilities for carrying vehicles cargo. It will also help transport combat and support elements of marine expeditionary units and brigades.

Under the LPD 17 programme, the ships will replace the US navy's ageing LST 1179 Newport-class tank landing ships, LKA 113 Charleston-class amphibious cargo ships, and the Anchorage-class dock landing ships (LSD 36), as well as Austin-class ships (LPD 4).

The navy has received six of 11 LPDs to date, while the remaining vessels are currently under different stages of construction.

Delivery of the new vessel is scheduled for mid-2017.

Navy's new gender-neutral carriers won't have urinals

The U.S. Navy's new class of carriers will be the first to go without urinals, a decision made in part to give the service flexibility in accommodating female sailors, the Navy says.

The change heralded by the Gerald R. Ford class of carriers – starting with the namesake carrier due in late 2015 – is one of a number of new features meant to improve sailors' quality of life and reduce maintenance costs, Capt. Chris Meyer said Wednesday.

Omitting urinals lets the Navy easily switch the designation of any restroom – or head, in naval parlance – from male to female, or vice versa, helping the ship adapt to changing crew compositions over time, Meyer said.

The Navy could designate a urinal-fitted area to women, of course, but the urinals would be a waste of space. Making the areas more gender-neutral is a relatively new consideration for the service, with most of its current carriers commissioned before it began deploying women on non-submarine combat ships in 1994.

But it wasn't the only reason for the move.

Urinal drain pipes clog more than toilets and therefore can be smellier and costlier to maintain, Meyer said.

"There's a lot more at play in the design objectives than (making the toilet areas) gender-neutral. We're saving money in maintenance costs, and we’re improving quality of life," said Meyer, manager of the Future Aircraft Carriers Program for the Naval Sea Systems Command.

Other quality-of-life updates, according to Meyer:

– Sleeping areas, or berthings, generally will be smaller, designed for fewer people per room. On current carriers, some berthings have more than 100 sailors each. On the Ford carriers, the number will be closer to 30 to 50 each.

– Heads will be attached to berthing compartments. Currently, many sailors have to traverse a passageway between a berthing and a head, meaning sailors who’ve just woken up have to dress up more for a trip to the head than they would if it were adjacent.

The new Ford-class features were first reported by the Navy Times.

Some sailors said that they're happy to lose the urinals because they're hard to clean and maintain, the Navy Times reported this week.

The Ford class is the future replacement for the Nimitz class. The Ford carriers are designed to allow more aircraft sorties, but with about 660 fewer crew members, according to the Navy.

The first three Ford carriers are scheduled to debut between 2015 and 2027, at a total projected cost of $37 billion. That cost includes non-recurring engineering expenses and research and development costs for the first carrier, the Navy says.

6,000 Tomahawks Later


The U.S. Navy has ordered another 200 Tomahawk cruise missiles for its ships and submarines. The navy continues to use Tomahawks in combat on a regular bases. Most of these uses are publicized, but some are not. Several hundred Tomahawks were used against Libya last year. The Tomahawk was introduced 29 years ago and over 6,000 have been manufactured so far. U.S. Navy has fired over 2,000 in combat and over 500 for training and testing. The U.S. Navy has over 3,000 Tomahawks on its warships or in storage.

The current Tomahawk, the RGM-109E Block 4 Surface Ship Vertical Launched Tomahawk Land Attack Missile weighs 1.2 tons, is six meters (18 feet) long, has a range of 1,600 kilometers, getting there at a speed of 600-900 kilometers an hour, flying at an altitude of 17-32 meters (50-100 feet), and propelled by a jet engine generating only 600 pounds of thrust. Accuracy is on a par with JDAM (10 meters/31 feet). The Block 4 Tomahawk can be reprogrammed in flight to hit another target and carries a vidcam to allow a missile to check on prospective targets.

The Block 4s were recently upgraded so that they can hit moving targets. This is mainly intended to turn the Tomahawk into an anti-ship missile, although it can also hit moving land targets. The Tomahawk has been a primary land attack weapon for surface ships and submarines since the 1990s. The Block 3 entered service in 1994, but the Block 4 was a big upgrade a decade later, adding GPS and the ability to go after a different target while the missile was in flight.

The United States is developing a successor to the Tomahawk cruise missile that will be heavier (2.2 tons), have a longer range (2,000 kilometers), and a larger (one ton) warhead. The new missile will be stealthier and use a combination of guidance and targeting systems (to improve the chances of success). Price will probably be the key factor in whether this new missile ever enters service. The new Cruise Missile XR (for Extended Range) will probably cost at least twice as much as the current Tomahawk.

The cruise missile, when it showed up in the 1980s, was one of the first UAVs, it just wasn't reusable. But UAVs that carry bombs and missiles and can be reused are going to provide competition for a new, $3 million, Cruise Missile XR.
