GAO Eyes Retirement Pay After 10 Years

By Rick Maze, Military Times, 31 August 2010

Eliminating retirement benefits for 20 years of service would hurt the military ? but allowing troops to earn reduced retirement benefits after 10 years of service, as long as they wait until age 65 to receive the pay, might give a boost to recruiting and retention, according to the Government Accountability Office.

The idea, which could increase the military’s retirement costs, comes at a time when Congress is looking for ways to cut federal entitlement programs.

An independent commission appointed to look at federal spend-ing is expected to report in December on cutting benefits, potentially including military benefits.

GAO’s input came in response to questions posed by Sen. Lindsey Graham, R-S.C., ranking Republican on the Senate Armed Services Committee’s personnel panel, about whether retirement benefits would be a greater boon to recruiting and retention if people were vested in benefits earlier in their careers.

He asked whether promising retirement benefits after 10 years of service would be a good way to encourage people to serve in time of war beyond one or two enlistments. Under most discussions about 10-year retirement vesting, benefits earned after 10 years of service would be less than those earned after 20 years, because retired pay still would be based on a combination of years of service and rank.

GAO said it is hard to see the immediate recruiting and retention benefits of promising retired pay after 10 years because the ser-vices are not having recruiting and retention issues.

GAO said deferred compensation such as retired pay or health benefits for retirees is “a relatively inefficient way” to influence people; it would be less expensive to just offer immediate cash bonuses. That is the same argument the Pentagon has used to try to hold down the size of military pay raises.

There are reasons to keep full retirement vesting in return for 20 or more years of service, GAO said. The current system “is meant to create a strong incentive for military personnel who stay beyond eight to 10 years to complete 20 years and leave soon thereafter,” analysts said.

But changing the initial vesting point from 20 years to just 10 might make sense if the goal is to keep people in the military who otherwise would get out after five years, GAO said.

Russian Subs Stalk Trident In Echo Of Cold War

By Thomas Harding, London Daily Telegraph, August 28, 2010

RUSSIAN submarines are hunting down British Vanguard boats in a return to Cold War tactics not seen for 25 years, Navy chiefs have warned.

A specially upgraded Russian Akula class submarine has been caught trying to record the acoustic signature made by the Vanguard submarines that carry Trident nuclear missiles, according to senior Navy officers.

British submariners have also reported that they are experiencing the highest number of "contacts" with Russian submarines since 1987.

If the Russians are able to obtain a recording of the unique noise of the boat's propellers it would have serious implications for Britain's nuclear deterrent. Using its sophisticated sonar, the Akula would be able to track Vanguards and potentially sink them before they could launch their Trident D4 missiles.

The Daily Telegraph has learnt that, within the past six months, a Russian Akula entered the North Atlantic and attempted to track a Vanguard. The incident has remained secret until now.

It is understood that the Russians stood off Faslane, where the British nuclear force is based, and waited for a Tridentcarrying boat to come out for its three-month patrol to provide the Continuous At Sea Deterrent.

While patrolling in the North Atlantic, there are a limited number of places the Vanguard is permitted to go and it is thought that the Akula attempted to track it on several occasions.

Navy commanders are understood to have ordered a Trafalgar-class hunter-killer submarine to protect the Vanguard. A recording of the Akula was made by the Trafalgar submarine's sonar operators and has been played to The Daily Telegraph.

"The Russians have been playing games with us, the Americans and French in the North Atlantic," a senior Navy commander said.

"We have put a lot of resources into protecting Trident because we cannot afford by any stretch to let the Russians learn the acoustic profile of one of our bombers as that would compromise the deterrent."

China Hits Bottom, Plants Flag

By Colin Clark, DoD Buzz, 26 August 2010

The People’s Republic of China has joined an elect group of four countries that have taken men as deep as 3,500 meters below the surface of the ocean. And in keeping with Chinese claims to huge amounts of the ocean surface and its depths, the crew planted a flag on the bottom in the South China Sea, much as Russia recently did in Arctic waters.

The story was reported on Chinese TV news and by the official Xinhua news service, making it almost certain that the event had policy repercussions, in addition to the nicely nationalistic side of the submersible crew and the craft’s designer having done something physically and technically challenging.

The flag planting was done with a submersible, not a submarine. Subs are independent and can go pretty much wherever they like. Submersibles, which are usually designed to go deeper and possess grappling arms of some type, usually are deployed from a mother ship and possess limited range. The Chinese submersible, Jiaolong, executed 17 dives in the South China Sea from May 31 to July 18. The deepest dive took them to 3,759 meters.

The flag planting, “highlights (again!) that China has laid claim to the South China Sea,” said Dean Cheng, the top Chinese defense expert at the Heritage Foundation here in Washington.

Islands and reefs in the South China Sea are claimed by China, Taiwan, Vietnam, Malaysia and the Philippines. My personal favorite clump of islands is those known as the Spratlys, where people have died over tiny lumps of coral so small it’s impossible to build permanent structures on them. The Spratlys may lie atop oil and gas deposits and they describe rich fishing areas.

At the end of last month a Defense Ministry spokesman said “China has indisputable sovereignty” of the South China Sea, though he allowed that the PRC would allow ship and aircraft passage “from relevant countries” if they comply with China’s interpretation of international law.

Cheng pointed to the fact that the Jiaolong was manned, saying China’s ability to operate at such depths will have economic and military repercussions as they undertake operations such as deep sea oil drilling and labor to supplement Ch8inese research into oceanography, a key discipline for submarine operations.

Diesel-Electric Submarines, The U.S. Navy’s Latest Annoyance

By Grace Jean, National Defense Magazine,

The Navy in recent months has had to contend with several provoking episodes at sea – Iranian small boats speeding at its cruisers, destroyers and frigates; Russian bombers flying over its carriers; and Chinese subs shadowing its warships.  Hard-to-detect submarines – such as quiet, diesel-electric boats – are particularly vexing, Navy officials say. They contend that an undersea arms race already has begun in the western Pacific.

Nations there in recent years have begun to acquire stealthy diesel-electric submarines. Some of those nations, say Navy officials, could one day threaten U.S. access to strategic coastal areas of the world or interrupt the flow of commerce around the globe.  Although the Navy has the world’s most technologically advanced fleet – including state-of-the-art nuclear attack submarines – officials acknowledge that these comparatively low-tech diesel-electric boats could give an enemy an asymmetric advantage.

“The beauty about a diesel submarine is that it has the potential to be far quieter than a nuclear submarine,” says Guy Stitt, president of AMI International, a Bremerton, Wash.-based company specializing in naval market analysis. Diesel boats are propelled by batteries when submerged and move through the water by diesel engines when on the surface.  Once they have powered up their batteries, the submarines can sail to the bottom of coastal waters and remain undetected for days. Though they can’t travel long distances or sail very quickly, advancements in technologies, such as air-independent propulsion and fuel cells, have allowed diesel submarines to extend their operational ranges underwater.  But perhaps their best selling point is their relatively inexpensive price tags. The Russians have sold diesel submarines for as little as $200 million and the French have exported their Scorpene submarines for $300 million.

“It is within the scope of many, many countries to be able to afford them. They don’t need a lot of them. They don’t need to sail them very far, and they don’t have to be particularly proficient with them,” says Vice Adm. Samuel Locklear, commander of the Navy’s Third Fleet, which prepares strike groups to deploy to the Pacific and the Middle East.

More than 39 nations possess diesel submarines. One of the latest tallies indicates a total of 377 ships in the world, says Richard Dorn, an analyst at AMI International. And there could be an uptick in the next few years.  With China continuing to increase the size of its navy, a number of neighboring nations also have begun to develop their undersea capabilities.   “There’s a push on in Asia that really seems to be driven by China,” says Stitt. Singapore, Malaysia and Indonesia all have closed deals on diesel submarines, and now Thailand is following suit.

Driving the market in part is Russia, which during the past 18 months has been aggressively selling ships, including its Kilo-class diesels.  “We’ve seen a huge increase in the number of sales that they’re booking for Kilos, primarily motivated by the need for funds to strengthen their second tier shipbuilding groups,” says Stitt. Since the end of the Cold War, Russia has lost many of its secondary shipyard suppliers – the engine, pump and valve manufacturers, piping companies and the like. But Russia is attempting to revitalize those small companies.

“They’re going out and making all these deals to sell submarines and ships and using those funds to reinvigorate the industry, which in turn will also benefit them in building up the Russian fleet,” says Stitt.   Russia has exported 30 Kilos around the globe and 26 are still in active service. It will deliver two more submarines to Algeria by 2010, five to Venezuela by 2020, and six to Indonesia by 2018. China received its 12th and final Kilo last year.  The number of Kilos that are being sold is particularly concerning because many of the submarines are equipped with Klub anti-ship cruise missiles.

Some nations have a desire for regional hegemony and want to strengthen their influence in an area. That’s most definitely the reason for President Hugo Chavez buying subs for Venezuela, says Stitt.   But for other nations, the reasons are less clear. “There’s a wide array of military assets you can buy, so why would you buy a diesel-electric submarine? As far as I know, it’s not to protect your own port,” says Locklear in an interview at Third Fleet headquarters perched atop Point Loma in San Diego.

That China’s submarines are surfacing boldly near U.S. warships is a telltale sign of newer advanced technologies, such as acoustic tiles and cavitation-reducing propellers, that are being employed on the submarines, says Stitt.  China’s new Song-class diesel submarines have tracked U.S. Navy ships operating in the seas near Japan and Taiwan. Last November, after China denied the USS Kitty Hawk’s port call in Hong Kong at the last minute, a Chinese submarine shadowed the carrier as it entered the Taiwan Straits on its return voyage to Yokosuka, Japan. In the late fall of 2006, a Song-class submarine surfaced within torpedo range of the Kitty Hawk off the coast of Okinawa, Japan.

Despite the tensions, those episodes and the topic of submarines did not come up directly in conversations with Chinese officials in January, when the commander of Pacific Command, Adm. Timothy Keating, visited the nation. “We watch them carefully. It’s an area of warfare at which they’re stretching a little bit,” he told reporters during a breakfast meeting in Washington, D.C. “Their numbers of submarines are increasing. The capabilities resident in those submarines are not unimpressive. They’re pretty good – we’re better.”

China’s fleet of nuclear and diesel submarines includes 10 Song class, 12 Kilo class, one Yuan class and 32 Romeo class.

“We know that they are continually expanding their reach in what they view as their own areas of interest, and that their submarine force is vital to expanding that reach,” says Locklear. The proliferation of diesel submarines in the Pacific is one of the major factors behind the Navy’s decision to move six submarines from the Atlantic Fleet to the Pacific Fleet, says Rear Adm. Joseph Walsh, commander of the Pacific Submarine Force. Because more than 140 diesel subs are within reach of critical “choke points” in the area, anti-submarine warfare is Pacific Fleet’s top war-fighting priority, he adds.

The Navy saw its anti-submarine warfare skills diminish after the end of the Cold War. In those days, enemy Soviet nuclear submarines were noisy, and could be detected with passive sonar.  But modern-day diesel submarines are not as easily heard, particularly in regions of the seas where biological life and merchant shipping can camouflage their acoustic signatures. It is there, in the noisy waters of the littorals, where detecting submarines can be a cat-and-mouse game, Navy officials say.

Rear Adm. John Waickwicz, who was the head of the Naval Mine and Anti-Submarine Warfare Command until he retired in January, says the Navy is looking at anti-submarine warfare in new ways. “When you talk about countries that have 30, 40, or 50 submarines, you can’t wait until they’re around you, because they’re going to overwhelm you,” he says. Potential enemies have figured that to defeat the U.S. Navy, they must “go out and buy submarines, and buy mines,” he says. The mine and anti-submarine warfare command is calling for the deployment of a network of sonobuoys over a wide expanse of ocean to detect enemy submarines. But the project has been marred by technological and funding problems. The most significant hitch is that the data collected by the sensors takes too long to analyze, says Waickwicz. “You need to do it in real time to take action on it.”

False alarm rates on many of the fleet’s current detection technologies are too high, Waickwicz adds. That forces commanders to waste resources on non-existent threats. Officials insist that the Navy’s anti-submarine warfare capabilities are the best in the business, but they acknowledge that it will take some time to hone the skills to combat stealthy diesel submarines. Waickwicz says that training has improved in recent years, but some individual units are not adequately prepared for at-sea operations.  For example, some units have demonstrated sonar operator proficiency on simulations that are not sophisticated enough to replicate the real environment, which puts the sailors at a disadvantage when they conduct operations at sea, says Rear Adm. Frank Drennan, the new commander of the Naval Mine and Anti-Submarine Warfare Command.  “The requirements are still the same – they just have to work on them in a challenging environment so that operators are truly proficient when they go to sea,” he says.

Hunting for quiet diesel submarines in the shallow waters of the littorals is akin to trying to identify the sound of a single car engine in the din of a major city, he says.  There are variations in the underwater topography, with sand bars, coral reefs and channels. Different depths of water and changing salinity and temperatures alter how sounds propagate. Marine life and merchant shipping also complicate the search by generating ambient noise.

The only technology that the Navy considers suitable for detecting and tracking diesel submarines is active sonar. It disperses signals out into the water where they bounce off of objects. Those echoes are captured by hydrophones and interpreted by sonar technicians. Contrary to popular belief, sonar is not like radar, which gives complete visibility of “hits” in the air. What sonar technicians see is a screen that is filled with vertical lines representing echoes from objects in the water. Discerning which line is a submarine and which one is a coral reef is a difficult and complex task, sailors say.

The Navy spent 40 years building a training range on the coast of Southern California – one of the most extensive in the world, officials say. Underwater sensors track ships’ locations and record operations during exercises.  Because the water and ocean bottom conditions are representative of many areas around the world, the range is an ideal location for training strike groups in anti-submarine warfare, says Locklear. But the Navy’s training there has been curtailed by ongoing litigation over the harmful effects of active sonar on marine mammals.

Under a federal judge’s ruling, ships were forbidden from using active sonar within 12 nautical miles of shore and had to steer clear of waters between the Santa Catalina and San Clemente islands during a joint training exercise in January for the Abraham Lincoln carrier strike group. Sightings of marine mammals at certain distances also prompted ships to take protective measures, such as powering down sonar or shutting the sensors off completely.

“We’re not able to employ the sonar, given those restrictions, in a realistic manner, and it just makes it real tough to assess whether the fleet is proficient at using the technology,” says Capt. Pete Tomczak, deputy director for training at Third Fleet.  The use of sonar by the Navy has been linked to mass marine mammal strandings on beaches in the Bahamas and the Canary Islands. Pending necropsy results, the death of a northern right whale dolphin that washed up Jan. 29 on the Navy’s San Nicolas Island could be connected to sonar use.

Locklear says the Navy tries to balance its responsibility to protect the environment with its job to prepare sailors for war. He expresses concern that the judge’s ruling, if extrapolated beyond Southern California, could hamper Navy training around the world. “If this becomes precedence setting, I think it will be very difficult for the United States Navy,” he says. “If there was a new technology on the horizon that made this irrelevant, we would be all over it. We just haven’t found it yet.”

With prospects of at-sea training diminishing, not only because of the litigation, but also as a result of rising fuel costs and other budget constraints, the Navy is searching for alternative ways to prepare its sailors for anti-submarine warfare. One option is to rely on simulators, says Waickwicz. But he points out that current simulations in the Navy do not replicate sonar accurately.   “It’s like playing ‘Pong’ in today’s game world,” he says. While the submarine forces have higher fidelity trainers, much of the rest of the fleet – especially surface ships – have sub-par simulations.

“Computer simulations can only go so far. There is still no substitute for at-sea practice against a real submarine,” says Pacific Fleet’s Walsh.  Because the U.S. Navy no longer operates diesel-electric submarines, it invites allied countries that own these boats to participate in exercises at Navy ranges on the east and west coasts. The Swedish Navy’s HMS Gotland collaborated most recently with various Navy commands in San Diego.

“It was very advantageous to have a diesel submarine crew for two years, to see how they thought, how they approached the issues to go against the ships,” says Waickwicz. “It really opened our eyes to diesel submarines and how active sonar is what you have to have in the strike group.”  The experience led to recent changes in the Navy’s anti-submarine warfare doctrine and tactics.
