U.S. Submarine in Asia Trip as Obama Seeks to Assure Allies

 

The Virginia-class fast-attack submarine USS North Carolina sits moored at Changi Naval Base in Singapore.

A U.S. nuclear submarine is making a port call in Singapore as the Navy showcases its ability to operate in shallow coastal waters after questions about the fitness of its Littoral Combat Ship for use in Asia.

The Virginia-class USS North Carolina was designed with littoral combat in mind, particularly for special operations and anti-mine warfare, its commanding officer Richard Rhinehart told reporters yesterday. It is the submarine’s second visit to the region since its commissioning ceremony in 2008.

U.S. Navy officers in the Pacific fleet have raised concerns that the Littoral Combat Ship may lack the speed, range and electronic-warfare capabilities to operate in the vast Asian waters. President Barack Obama, who made a week-long trip to the region to shore up ties with key allies, has said the U.S. would protect East China Sea islands administered by Japan that are claimed by China and reaffirmed defense treaty obligations with the Philippines, embroiled in a dispute with China in the South China Sea.

“This is not the first Virginia-class to deploy to the region,” said Commander Rhinehart. “This does, however, represent a continued effort by the U.S. to send the best technology and capabilities into the Pacific theater.”

The North Carolina, which has been on its current deployment for four months, is the first class of submarine equipped with a periscope system consisting of two photonics masts with infrared and laser range-finding capability that makes it suitable for littoral waters, Rhinehart said. It can launch torpedoes and Tomahawk land attack missiles, has counter-mine capabilities and a nine-man lockout chamber to allow swimmers to exit, he said.

GAO Report

The Littoral Combat Ship, designed to operate in coastal waters, “might be better suited to operations” in the smaller Persian Gulf, the U.S. Government Accountability Office said in a report obtained by Bloomberg News this month. The Navy should consider buying fewer of the ships if its limitations prevent effective use in the Pacific, the report said, following others that have questioned the cost, mission and survivability in combat of the ship.

U.S. Defense Secretary Chuck Hagel said in a Feb. 24 memo that “considerable reservations” led him to bar negotiations for any more than 32 of the vessels, 20 fewer than called for in the Navy’s $34 billion program. The Littoral Combat Ship is made in two versions by Lockheed Martin (LMT) Corp. and Austal Ltd.

Operating in shallow waters is a bigger challenge because there are more objects for sound to bounce off, the mix of salt water and fresh water can cause changes in buoyancy, and there is a greater likelihood of encountering other ships such as fishing vessels, Rhinehart said.

Projecting Power

The U.S. Navy will probably keep buying Littoral Combat Ships because it doesn’t really have an alternative, according to Richard Bitzinger, a senior fellow at the S. Rajaratnam School of International Studies in Singapore who focuses on regional military issues.

“One of the reason why they’re building Littoral Combat Ships is to give them the ability to project power from the water close to land,” he said. “Asia’s important, Southeast Asia in particular is important, and the United States is going to be demonstrating its intention to stay here.”

Obama Visits

Tensions in Asia have been on the rise as China asserts its military muscle and presses claims to territory and resources. In November, China prompted criticism from the U.S., South Koreaand Japan after it announced an air defense identification zone over a large part of the East China Sea. In January, it introduced fishing rules in the South China Sea requiring foreign vessels to seek permission before entering waters off its southern coast.

China will make “no compromise, no concessions” in such disputes and is ready to fight and win any battle, General Chang Wanquan said on April 8 in Beijing.

China has said central government defense spending will rise 12.2 percent this year to 808.2 billion yuan ($129.3 billion), at a time the Pentagon is cutting back, proposing a budget for the coming fiscal year of $495.6 billion and to reduce the Army’s personnel by 6 percent by 2015. China’s increased budget threatens to end U.S. military superiority, Frank Kendall, under secretary of defense for acquisition, technology and logistics, said Feb. 11.

Counter, Contain

Obama, speaking on April 24 after a meeting in Tokyo with Japanese Prime Minister Shinzo Abe, said a security treaty between the U.S. and Japan covers “all territory that is administered by Japan.” The commitment to defend the area is longstanding and he was not drawing a new “red line” with China over the issue, Obama said.

Yesterday, the Philippines and the U.S. signed an agreement that will boost the rotational American troop presence in the Southeast Asian nation.

The U.S. is seeking to work cooperatively with China in the region, Obama said at a briefing in Manila with Philippine President Benigno Aquino. “Our goal is not to counter China, our goal is not to contain China,” he said. “Our goal is to make sure that international rules and norms are respected and that includes in the area of maritime disputes.”

“We have a lot of regional allies,” said the North Carolina’s Commander Rhinehart. “The entire Asia area is very important and we’re here with our partner nations trying to promote security and the rights of all nations large and small.”

“Red October” submarine returns to Connecticut from last deployment

USS Dallas

USS Dallas

The submarine that starred in “The Hunt for Red October,” the USS Dallas, returned from its last overseas deployment Monday. Next year, after 33 years in the fleet, the Dallas will be inactivated.

Tom Clancy’s Cold War thriller made the Dallas famous, but in Navy circles it is better known for being the first attack submarine to carry a dry-deck shelter, which houses a vehicle for launching and recovering special operations forces.

“Of all the submarines that would be finishing up their service life, there are a couple out there that people know by name, and Dallas is one of them,” said Capt. David A. Roberts, who commanded Dallas from 2007 to 2009. “It kind of adds to the moment. ‘The Hunt for Red October’ submarine we all know and love from the movies is going to be finishing up its service life soon.”

But, Roberts said, he always tells people who ask about the Dallas that it has “done a lot more than just being in the movies.”

“Think about how the world has changed,” said Roberts, who now leads the Submarine Learning Center. “The missions Dallas was built for initially back then, in the late 1970s and early ‘80s, are so much different than in 2013. And she has stood the test of time and been able to keep step with the changing world, the challenging world.”

The Dallas (SSN 700) returned to the Naval Submarine Base on Monday after operating in Europe and the Middle East and traveling more than 34,000 miles during nearly seven months at sea.

While all deployments are memorable, Cmdr. Jack Houdeshell, the current commanding officer of the Dallas, said the last deployment comes second only to the maiden deployment for a submarine.

And on this deployment, Houdeshell added, the crew and the ship “showed the world what we can still do.”

The Dallas will continue to support training and other missions until September, when the preparations begin in earnest for the decommissioning, Houdeshell said.

One of 42 Los Angeles-class attack submarines remaining in the fleet, the Dallas was commissioned in 1981 as the seventh member in a class of 61 submarines. It has deployed to every operational theater around the world ever since.

The submarine circumnavigated the globe and transited the Panama Canal in 1984 and participated in Operations Desert Shield/Storm in the early 1990s.

Master Chief Electronics Technician Tomas A. Garcia, who was the chief of the boat on Dallas from 2010 to 2012, said the Dallas was known for delivering Navy SEALs, but the equipment was removed shortly before he reported aboard. Guided-missile submarines and some Virginia-class submarines carry the dry-deck shelters now, he added.

Roberts, Houdeshell and Garcia all said serving aboard Dallas was the highlight of their careers.

Garcia, a Texas native who is now the department master chief for Basic Enlisted Submarine School, led about 100 Naval Submarine School students to the pier on Monday so they could attend a submarine homecoming for the first time.

“There is no better way for them to really get a full appreciation for what it means to deploy on a submarine,” Garcia said.

Seeing the families and feeling the excitement of the homecoming, Garcia added, “really drives home” the importance of the submarine force’s missions and of the family support at home. Garcia said he also watched “The Hunt for Red October” with his family on Sunday night to celebrate the Dallas’ impending arrival.

Seaman Jose Cruz, 19, cheered “Hooyah, Dallas” with his classmates as the Dallas arrived next to the pier. Cruz said he felt as if he was being welcomed into the traditions of the submarine force.

“For all of us,” he said, “this will be something to remember.”

Houdeshell said Monday was an emotional day because he was thrilled to see his family and see the sailors reunited with their families, especially in time for Thanksgiving, but he also knew that after he brought his ship in “she’s not going to go out and do it again.”

“I think the real measure of the Dallas is the crews that served on the Dallas and have gone out throughout the fleet,” he said. “Even when the ship is gone you will still have the Dallas spirit out in the fleet from the sailors that served on board.”

The submarine itself may live on too, as a centerpiece for a maritime museum. A nonprofit foundation, the Dallas Maritime Museum Foundation, plans to build a museum featuring Navy ships and other vessels named after the city.

“As much as I hate to see my old ship eventually be decommissioned,” Roberts said, “I think memorializing her in Dallas would be a perfect ending to a great career.”

Ohio-Class Ballistic Submarine Remains Priority for US Navy

The Navy views the Ohio-class replacement ballistic missile submarine as its top priority, indicating it would be prepared to slash other ship programs to build the 12 submarines it needs.

Senior congressional aides noted that the Navy would consider reducing its 11-aircraft carrier fleet before it would scale back its plans to replace the Ohio-class ballistic submarine.

The reasons, according to the Navy, include the central role the ballistic missile submarines play as the most survivable part of nuclear deterrent force, the aging of the existing ballistic submarine fleet, and a need to keep a healthy industrial base.

“We are committed to sustaining a two-ocean national strategic deterrent that protects our homeland from nuclear attack, from other major war aggression and also access and extended deterrent for our allies,” said Rear Adm. Richard P. Breckenridge, director of the Navy’s Undersea Warfare Division.

To provide a viable deterrent of 10 forward-deployed submarines in the Atlantic and Pacific, the Navy requires at least 12 submarines at any given time.

“If we don’t build these 12 [ballistic missile submarines] on this timeline … that’s just [an] astronomical challenge for us to be able to maintain our vibrant and credible two-ocean deterrent — to deter bad behavior from powerful adversaries,” he told the House Armed Services Subcommittee on Seapower and Projection Forces last week.

As a result of budget challenges last year, the Ohio-class replacement program was delayed two years.

“It, to me, is mind-staggering how much risk as a nation that we’ve taken with regard to this recapitalization timing decision,” Breckenridge said. “There is no allowance for any further delay.”

The Navy once had 18 Ohio-class ballistic missile submarines. At Congress’ direction, four of those submarines were converted to cruise-missile-carrying submarines, leaving 14 ballistic missile subs.

Since then, the Navy decided on a plan to replace those 14 submarines with 12 of the new ballistic missile submarines. The last time Congress started to buy a ballistic missile submarine, President Richard Nixon was in office. Procurement of the new submarines won’t begin until 2021.

“Our ballistic missile submarines are the bedrock underlying our national nuclear deterrent,” Breckenridge said. “Americans are asked to invest in replacing this force only once every other generation. … Recapitalizing this force is a solemn duty we have to the nuclear security of future Americans as well as allies.”

Declining Power – USN Submarine Force

Admiral: U.S. submarine forces decline as forces of China, Russia, Iran advance undersea warfare capabilities

China, Russia, and Iran pose regional and strategic submarine threats and are building up undersea warfare capabilities as the Navy is cutting its submarine force by 30 percent, the admiral in charge of Pentagon submarine programs told Congress on Thursday.

Rear Adm. Richard Breckenridge, director of Navy undersea warfare programs, said the decline of U.S. submarines is placing a key U.S. military advantage at risk.

“Our adversaries are not standing still, and so even though we have an advantage and we have a lead, we can’t sit on our lead,” Breckenridge told a hearing of the House Armed Services seapower subcommittee.

“We have to continue to move or we do have the potential within 20 years of losing this crown jewel, this advantage that we have in the undersea domain,” he said.

Breckenridge then outlined advances in the submarine warfare programs of China, Russia, and Iran.

China’s submarine warfare power is advancing in both numbers of submarines and growing sophistication and missile capability.

Beijing’s submarines currently are “predominantly a maritime, regional undersea force,” he said.

“They predominantly use their undersea forces to threaten the presence of our surface ships, to be able to shoulder off the positive, stabilizing influence of our naval forces in an anti-surface warfare dimension,” Breckenridge said.

However, he warned that China’s submarine programs are “growing towards more of a global strategic undersea force.”

China’s new Jin-class missile submarines are equipped with JL-2 missiles that “will put them into the stage of using the undersea for more than just maritime regional control,” he said.

China’s navy is also building conventionally armed, guided-missile submarines, he said.

“I think that the capability, the quality of their submarines will improve as we march forward a couple of decades,” Breckenridge said. “But right now, there is a capacity challenge that’s unique to what the Chinese navy has.”

Defense officials revealed to the Free Beacon in July that the first sea patrols of China’s new strategic missile submarines will begin next year, the first time Beijing will send strategic missile submarines far from its shores.

Currently, China has three Jin-class submarines each equipped with 12 JL-2 missiles. China calls the Jin-class the Type-094.

The National Air and Space Intelligence Center reported in July that the JL-2 will give China for the first time the capability to target portions of the United States from locations near China’s coasts.

After deploying at least five Jin-class subs, China currently is working on a more modern version missile submarine called the Type-096.

The Pentagon’s annual report to Congress said China has placed a high priority on building up its submarine force and currently has more than 55 submarines, including two new Shang-class attack submarines and four improved variants of that sub. It is building a new Type-095 guided missile attack submarine in the next decade, the report said.

The Chinese also have 12 Russian-made Kilo-class submarines, some armed with SS-N-27 anti-ship cruise missiles, 13 Song-class and eight Yuan-class attack submarines. Up to 20 Yuan-class subs will be deployed in the future.

Breckenridge said Russia is building two new classes of advanced submarines called the Borei-class nuclear missile submarine and a conventional, guided-missile class called Severodvinsk. He said the Russian submarine program is at the “global strategic level of power.”

“It is more than just a region,” he said. “It is the ability to control the seas, it is the ability to do land attack from covert positions. It has a much larger utility than just a maritime sea-control, sea-denial perspective alone, and the Russians have always maintained a very capable submarine force.”

While the U.S. Navy currently has the advantage over Russia in submarine warfare capabilities, “they are a close second with regard to their capability and with regard to their shipbuilding industry and the capabilities they’re putting into their new classes of submarines,” he said.

Three Borei-class submarines are now deployed and at least five more could be built, he said.

“There’s been talk of a higher number of SSBNs [strategic missile submarines] within their force,” Breckenridge added. “But that machine is running. Those very good quality ballistic missile submarines are being produced in Russia.”

The Severodvinsk class of guided missile submarines will have an “eight-pack” of missile tubes, twice the number on U.S. Virginia-class attack submarines.

“So they see the importance of the concealment of the undersea to bring potency with that, that can be threatening at a strategic level,” Breckenridge said. “And again, we are mindful of that and we are prepared to be able to counter that.”

Tehran’s submarine force of three Russian Kilo-class submarines, one indigenous Nahang-class submarine and an estimated 12 Ghadir-class midget submarines, poses a regional threat.

“If you look at Iran, they, like many other countries, use the undersea domain from a purely maritime, sea-denial local region type of influence, much like we did in World War II in the Pacific,” Breckenridge said, “to hold at risk predominantly surface warships.”

“It is a disruptive force, a challenging force and one that we deal with regard to our ability to project stabilizing influence around the globe,” the admiral said.

Rick Fisher, a China military affairs analyst with the International Assessment and Strategy Center, said the “capacity” challenge mentioned by Breckenridge is real.

“The Chinese Navy may have up to 53 somewhat older to quite modern non-nuclear propelled attack submarines plus five more nuclear powered attack submarines for a total of 58,” Fisher said, adding that the force could be much larger.

“A possible force of 92 Chinese submarines means that U.S. Navy today is facing a very formidable challenge that requires that U.S. submarine levels remain well above 50 ships in order to prevent rapid combat attrition,” he said.

Breckenridge said the submarine programs of the three potential adversaries are advancing and “we have to be mindful of to make sure that we as a nation preserve this unique advantage that we have in the undersea domain.”

By contrast, the U.S. submarine force will decline by 25 percent over the next 15  years as a result of a “gradual consequence of a long list of choices made over many years,” he said.

The total number of submarines will drop from 75 to 52, a 30 percent decline, he said.

The missile-firing strike payload volume from submarines will decline by over 60 percent as the result of retiring guided-missile and attack submarines, he said.

The forward-deployed submarines around the world will decline by over 40 percent, despite building two Virginia-class attack submarines per year, he said.

To address the growing need for submarine power with the declining force, Breckenridge said the Navy has four priorities for its submarine strategy.

They include sustaining the sea-based nuclear deterrent with a new missile submarine to replace Ohio-class submarines. The follow-on has been delayed for 20 years and “it is now time to make the necessary investments to support procurement of the first Ohio replacement in 2021,” Breckenridge said. “There is no allowance for any further delay.”

To prevent the worsening decline in attack submarines, the Navy must continue the two-per-year pace of Virginia-class submarines, add a new more efficient missile launch payload module to Virginia submarine, and restart production of torpedoes.

Subcommittee Chairman Rep. Randy Forbes (R., Va.) said during the hearing that defense spending cuts are harming the Navy.

“It’s apparent to me that the largest threat to the United States Navy is of our own making,” Forbes said of the defense spending crisis.

“I continue to believe that the undersea warfare capabilities provided by our United States Navy provide a preeminent role in the control of the global commons,” Forbes said. “These capabilities provide the United States with the key asymmetric advantage over any potential aggressor. Even in a time of declining resources, it’s crucial that our nation continue to retain our strategic advantage in undersea warfare.”

USS Cod submarine starts engines & fires its cannon

CLEVELAND — On Monday, the USS COD Submarine Memorial honored the men and women who built the 312-foot submarine 70 years ago by firing its cannons and starting its engines.

The Cleveland National Air Show is usually held over the the Labor Day weekend.

The Labor Day Sea Show aboard the WW II submarine is in response to the cancellation of the Cleveland National Air Show

“We can’t have a quiet Labor Day on the lakefront,” said Paul Farace, director of the USS COD Memorial.

The 312-foot long submarine started to fire hourly salutes from her 5-inch deck gun at 11 a.m. and will continue until 5 p.m. Her diesel engimes fired up at noon, 2 p.m., and 4 p.m.

The fully restored COD is open daily until September 30, from 10 a.m. to 5 p.m.

Submariner proposes to his boyfriend on dock as submarine returns to Conn. from deployment

In this Monday, Aug. 12, 2013 photo provided by the U.S. Navy, Petty Officer 2nd Class Jerrel Revel, left, proposes to his boyfriend Dylan Kirchner during the homecoming of the USS New Mexico at the submarine base in Groton, Conn., after the ship’s inaugural six-month deployment. They have not set a wedding date. Defense officials estimate there are 18,000 same-sex couples in the active-duty military, National Guard and Reserves. It’s unclear how many of those are married.

GROTON, Connecticut — A Navy sailor returning from a six-month deployment emerged from his submarine, dropped to one knee and proposed to his boyfriend during the homecoming celebration in Connecticut for USS New Mexico.

About 200 people were gathered at the dock of the Naval Submarine Base New London where Machinist’s Mate Jerrel Revels proposed to Dylan Kirchner. Kirchner said he had thought about getting married but the proposal Monday came as a surprise.

“I didn’t really care everybody was around. It felt just like the two of us,” Kirchner told The Day of New London

The couple has not set a wedding date.

The repeal of the ban on openly gay military service took effect in 2011.

Defense officials estimate there are 18,000 same-sex couples in the active-duty military, National Guard and Reserves. It’s unclear how many of those are married.

The attack submarine traveled more than 34,000 miles over six months and stopped at ports in Norway, Scotland and Spain. It marked the first deployment for more than 70 percent of the crew. The sub was commissioned in 2010 and is the second Navy vessel to be named for New Mexico.

Man Restores Submarine, Writes Book – USS Drum

Man Restores Submarine, Writes Book

Thomas Bowser, the man tasked with restoring the U.S.S. Drum at Battleship Park has written a book about the submarine.

Bowser signed copies of his book “The Three Lives of the U.S.S. Drum” on Sunday.

Bowser believes that preserving history of submarines while sharing the story about the crew’s challenges makes a unique story worthy of a book.

“I did a lot of the work before just to put it out for visitors to see and November I decided to turn it into a book and compile it all together,” says Bowser.

US – Navy abandons plan to fix nuclear sub burned in Maine

The repairs were expected to cost $450 million, after a man set fire to it at the Portsmouth Naval Shipyard in 2012.

The Navy has cancelled plans to repair the fire-damaged U.S.S. Miami submarine at Portsmouth Naval Shipyard in light of higher-than-anticipated costs and federal budget cuts, officials announced Tuesday.

Smoke rises from a Portsmouth Naval Shipyard dry dock as fire crews respond Wednesday, May 23, 2012 to a fire on the U.S.S Miami nuclear submarine at the Portsmouth Naval Shipyard on an island in Kittery, N.H in 2012. 

The Navy has cancelled plans to repair the fire-damaged U.S.S. Miami submarine at Portsmouth Naval Shipyard in light of higher-than-anticipated costs and federal budget cuts, officials announced Tuesday, Aug. 6, 2013. Above, a 2004 photo of the sub in Groton, Conn.

The Navy estimated it would take an additional $390 million in Fiscal Year 2014 to repair the Miami, a nuclear-powered submarine severely damaged at the Maine shipyard in 2012. As a result, the submarine will be permanently removed from service and the repair money diverted elsewhere.

“The decision to inactivate Miami is a difficult one, taken after hard analysis and not made lightly,” Rear Adm. Rick Breckenridge, director of Undersea Warfare with the Navy, said in a statement Tuesday evening.

“We will lose the five deployments that Miami would have provided over the remaining 10 years of her planned service life, but in exchange for avoiding the cost of repairs, we will open up funds to support other vital maintenance efforts, improving the wholeness and readiness of the fleet.”

The decision will likely come as a blow to Portsmouth Naval Shipyard, one of four public shipyards operated by the Navy. Located in Kittery, the shipyard employs roughly 4,700 civilian workers.

The repairs were expected to cost approximately $450 million and continue into the spring of 2015. The man who set fire to the sub, 25-year-old Casey James Fury, was sentenced to 17 years in prison and ordered to pay $400 million in restitution last month.

Fury wanted to get out early from work at the Portsmouth Naval Shipyard when he set the fire.

“This was the worst fire I’ve ever seen,” said Eric Hardy, a firefighter at the shipyardsaid. “If it weren’t for sheer luck, we would have had a death on that boat.”

Prosecutors said 50 people were aboard the submarine when the fire started, and five firefighters were injured fighting the blaze throughout the night.

US – SSBNX Under Pressure: Submarine Chief Says Navy Can’t Reduce – Video Clip

SSBN Force Level Requirements: It’s Simply a Matter of Geography

By Rear Adm. Richard Breckenridge Director, Undersea Warfare, OPNAV N97

There have been recent claims that today’s ballistic missile submarine force is operating with excess capacity and, therefore, force reductions to save resources may be in order. As I have noted in response to a recent op-ed, this supposition is untrue – in fact, our lean SSBN force is providing the cornerstone of our national security at a pace that has remained essentially constant since the late 1990s. Even so, questions about the size and capability of our future at-sea deterrence are appropriate to consider as we recapitalize this national asset. Given past force structure reductions from the “41 for Freedom” SSBN force of the 1960s and 1970s, to the 18 Ohio-class SSBNs of the 1980s and 1990s, to our current force of 14 SSBNs, one might wonder, “What is the minimum number needed for strategic deterrence?” Given advances in technology and the changing scope and complexity of post-Cold War deterrence, is there a way to “do more with less” as we field the next class of SSBNs?

The Mission: Delivering survivable nuclear deterrence from large open-ocean areas

The purpose of the SSBN force is to deter nuclear attack against the United States and against our friends and allies. Our “boomers” do this as part of a nuclear triad. The SSBN role is to provide an assured response capability that is survivable, reliable and robust enough to act as compelling deterrent against a nuclear strike from a foreign power. To make sure our SSBNs are survivable, they are operated from bases giving them access to the broad ocean areas in both the Atlantic and the Pacific. They are stealthy – both in transit and on station. They are operated in a manner that makes their locations unpredictable, while still ensuring that our adversaries know that we have the ability to hold them at risk. This enduring, certain deterrent force acts as an important stabilizer; it is always there and always at the ready.

Our Current and Future SSBN Force: A case study in system optimization

An unarmed Trident II D5 missile launches from the Ohio-class fleet ballistic-missile submarine USS Nevada (SSBN 733) off the coast of Southern California, March 1, 2011. The test launch was part of the U.S. Navy Strategic Systems Programs demonstration and shakedown operation certification process. The successful launch certified the readiness of an SSBN crew and the operational performance of the submarine’s strategic weapons system before returning to operational availability. The launch was the 135th consecutive successful test flight.

Our SSBN force has been “optimized for leanness” based on more than 50 years and 4,000 patrols of proven performance. The deterrent value we provided with 41 SSBNs we now provide with 14 Ohio-class SSBNs. This 65 percent force reduction is a result of two impressive technological developments – the extended range of the D5 missile and quieting technologies that make our SSBNs that much harder to find, even by a persistent and determined adversary. Our boomers are able to exploit the vast reaches of the Atlantic and Pacific Oceans to patrol silently while within range of key targets to hold an aggressor at risk.

As we return to our question of the leanest force capable of providing this credible and persuasive deterrent, our answer simply comes down to world geography 101 principles. Because the Pacific Ocean is larger, we operate two additional SSBNs in the Pacific to accommodate range and survivability considerations. Six SSBNs in the Pacific and four in the Atlantic is the bare minimum required to provide uninterrupted alert coverage for the combatant commander.

So if 10 SSBNs is our absolute minimum, why do we need 14 today? The reason hinges on the three-year refueling overhaul at the mid-life of each SSBN removing them from strategic service. Today, of our 14 SSBNs, we operate on average 11 to provide vital nuclear deterrence. Based upon other electronic system modernizations, this minimum force level occasionally dips to 10 operational SSBNs. One important historical note is relevant to the refueling overhaul discussion. The Ohio-class core life exceeded the design estimates of 15 years and the Navy was able to postpone mid-life refueling by six years.  Naval Sea Systems Command engineers then conducted detailed technical analysis of all other shipboard systems and extended the service life of our Ohio class from 30 to 42 years – a mind-staggering 40 percent life extension. This technological feat saved the country substantial budgetary resources, reaping a greater return from the initial investment in this SSBN class; essentially four less SSBNs will be procured during this century as a result of this achievement.

The good news is that this legacy of lean success is being imprinted in the DNA of the new Ohio replacement SSBN. The engineers at NAVSEA and our partners in industry are designing a new boomer with a 42-year service life and a reactor core that will not require refueling throughout the life of the ship. This will reduce the class mid-life overhaul by one-third and we will be able to deploy our 10 operational SSBNs with a force of just 12 total SSBNs.

If you want to see a “lean, mean fighting machine,” look no further than our current and future ballistic missile submarine force.

US -Eugene Wilkinson (1918-2013): Navy Commanding Officer of First Nuclear Submarine

 

The US Navy gives recognition and all salutes to Vice Admiral Eugene P. Wilkinson, who passed away last July 11 at the age of 94, as reported in NavyTimes.

Wilkinson made history as the first commanding officer to have full command over Nautilus, the Navy’s first nuclear-powered submarine. As the Nautilus made its maiden voyage, Wilkinson issued a message: “Underway on nuclear power”His career in the Navy spanned 34 years, starting from his commissioning in 1940.

His credentials include a Silver Star for his services during World War II, as well as working as the Naval Operations for Submarine Warfare’s deputy chief prior to his retirement in 1974. Wilkinson also powered the Institute of Nuclear Power Operations as its first president and CEO. The organization emphasizes the importance of safety in nuclear power plants. Aside from his command of the historic nuclear sub, he also commandeered the first nuclear-powered cruiser called Long Beach.

Navy Staff director Vice Adm. Richard Hunt expressed his respect for the departed veteran, in behalf of the entire Navy fleet. “He was a pioneering leader, an outstanding shipmate, and he will be sorely missed by his community and the Navy family,” Hunt said. –
