Navy leaders now say it will be possible to build more Virginia-class attack submarines at a faster pace than currently planned as part of an aggressive move to address and counter Russian and Chinese submarine expansion.
Navy leaders have consistently talked about an expected submarine shortfall in the mid 2020s and that more attack submarines were needed to strengthen the fleet and keep stay in front of near-peer rivals such as Russia and China.
Addressing the US Navy submarine shortage is now of critical or growing importance given China's growing ability to hit the United States with a nuclear-armed missile. The Navy, naturally, seeks to maintain its considerable technological advantage in the undersea domain, something which could increasingly be challenged in coming years.
"With the right missile China now has the maritime capability to strike directly at the homeland - we have lived in they are now the second nation that possesses the ability to do that. There is not just one country able to do that but two, underscoring the important of strategic deterrence," Richard said.
Virginia-class technology, including quieting abilities, Large Aperture Bow sonar and increased Tomahawk firepower with the upcoming integration of Virginia Payload Modules -- can likely help Navy submarines challenge or overcome anti-access/area-denial challenges posed by potential adversaries.
Richard cited progress on the proposed plan, to be articulated in the service's 2018 five-year spending plan called a Program Objective Memorandum, or POM. Navy officials tell Scout Warrior the POM delibrerations will be "open" until the President formally submits next year's service budget proposal.
The Virginia-Class Submarines are built by a cooperative arrangement between the Navy and Electric Boat, a subsidiary of General Dynamics and Newport News Shipbuilding, a division of Huntington Ingalls Industries.
Each industry partner constructs portions or “modules” of the submarines which are then melded together to make a complete vessel, industry and Navy officials explained.
Various sub-building industry executives have indicated that this might be possible. One industry source told Scout Warrior that the submarine building community would support whatever the Navy and Congress call for.
“We’ll support Navy programs,” the source said.
Navy Leaders Want More Attack Submarines:
The prospect of an acceleration comes as Navy commanders tell Congress they would like to see the fast arrival of more Virginia-Class attack submarines added to the Pacific Fleet.
Pacific Commander Harry Harris told Congress earlier this year that he would like to see more submarines in his area of operations.
“The Pacific is the principle space where submarines are the most important warfighting capability we have. As far as Virginia-Class submarines, it is the best thing we have,” Harris told lawmakers. “As I mentioned before, we have a shortage in submarines. My submarine requirement is not met in PACOM (Pacific Command).”
With their technological edge and next-generation sonar, the platform can successfully perform crucially important intelligence and surveillance mission in high-risk areas inaccessible to surface ships. For this reason, Virginia-Class attack submarines are considered indispensable to the ongoing Pentagon effort to overcome what’s talked about in terms of Anti-Access/Area-Denial wherein potential adversaries use high-tech weaponry and sensors to prevent U.S. forces from operating in certain strategically vital areas.
Virginia-Class Attack Submarine Technology:
Virginia-Class subs are fast-attack submarines armed with Tomahawk missiles, torpedoes and other weapons able to perform a range of missions; these include anti-submarine warfare, strike warfare, covert mine warfare, ISR (Intelligence, Surveillance, Reconnaissance), anti-surface/ship warfare and naval special warfare, something described as having the ability to carry and insert Special Operations Forces, Navy program managers have said.
Compared to prior Navy attack subs like the Los Angeles-Class, the Virginia-Class submarines are engineered to bring vastly improved littoral warfare, surveillance and open ocean capabilities, service officials said.
For instance, the ships can be driven primarily through software code and electronics, thus freeing up time and energy for an operator who does not need to manually control each small maneuver.
“What enables this is the ship control system that we use. You can drive the ship electronically. This allows you the flexibility to be in littorals or periscope depth for extended periods of time and remain undetected,” former Virginia-Class attack submarine program manager Capt. David Goggins said several years ago.
The Virginia-Class submarine are engineered with this “Fly-by-Wire” capability which allows the ship to quietly linger in shallow waters without having to surface or have each small move controlled by a human operator, Goggins added.
“There’s a person at the helm giving the orders of depth and speed. There’s always a person in the loop. The software is telling the planes and the rudder how to move in order to maintain a course and depth. You still have a person giving the electronic signal,” he said.
Also, unlike their predecessor-subs, Virginia-Class subs are engineered with what’s called a “Lock Out Trunk” – a compartment in the sub which allows special operations forces to submerge beneath the water and deploy without requiring the ship to surface, service officials explained.
“SEALs and Special Operations Forces have the ability to go into a Lock Out Trunk and flood, equalize and deploy while submerged, undetected. That capability is not on previous submarine classes,” Goggins added.
The Block III Virginia-Class submarines also have what’s called a Large Aperture Bow conformal array sonar system – designed to send out an acoustic ping, analyze the return signal, and provide the location and possible contours of enemy ships, submarines and other threats.
Unlike their “SSBN” Ohio-Class counterparts armed with nuclear weapons, the Virginia-Class “SSN” ships are purely for conventional attack, Navy officials said.
Thus far, more than ten Virginia-Class subs have been delivered to the Navy, and seven are currently under construction. Like other programs, the Virginia-Class submarines are broken up into procurement “Blocks.”
Blocks I and II totaling ten ships, have already been delivered.
The program has also delivered its first Block III Virginia-Class Submarine, the USS North Dakota.
The Block III subs, now under construction, are being built with new so-called Virginia Payload Tubes designed to lower costs and increase capability.
Instead of building what most existing Virginia-Class submarines have -- 12 individual 21-inch in diameter vertical launch tubes able to fire Tomahawk missiles – the Block III submarines are being built with two larger 87-inch in diameter tubes able to house six Tomahawk missiles each.
“For each one of these tubes you have hydraulics and you have electronics. What we did for Block III is we went to two very large Virginia Payload Tubes – now you have two tubes versus twelve. It is much easier to build these two tubes,” Goggins said.
Although the new tubes were conceived and designed as part of what the Navy calls its “Design for Affordability” strategy to lower costs, the move also brings strategic advantages to the platform, service officials say.
“In the future, beyond Tomahawk -- if you want to put some other weapon in here-- you can,” Goggins said.
Also, for Block V construction, the Navy is planning to insert a new 97-foot long section designed to house additional missile capability. In fact, the Navy has already finished its Capabilities Development Document, or CDD, for what’s called the “Virginia Payload Modules.”
