Ohio Submarine Class - Ballistic missile submarine USS Henry M. Jackson (SSBN 730) blue crew transited Hood Canal on September 30, 2015 as they returned home after a routine strategic patrol.
The Navy's mandate to provide "deterrence strategic defense" with ballistic missile submarines serves two goals: development of new boats remains on schedule and older boats reach the end of their expected service lives.

The latter isn't easy — the Navy is counting on Ohio-class ballistic missile submarines (SSBNs) to be around for every 42 years, something like that. USS Boomer, the longest-serving American submarine
Navy Looking To Extend Ohio Ssbns To Add To Columbia Class Margin
(SSGN-726) has been around for more than 34 years and has eight more to do - a command that includes Capt. Scott Papponen, his team at Naval Systems Command (NAVSEA) and other Navy offices.
"We have a very good, well-designed ship with a 30-year service life," Pappano, program manager for strategic and attack submarines at NAVSEA, told USNI in a Jan. 28 interview. in the year
Many of the ideas and challenges discussed 20 years ago — on the hull, mechanical and electrical (HMA&E) side and the passive electronic systems (NPES) side — are now coming to the fore, he said.
Going into the life extension effort, it was clear that the electronics needed to be updated. But recently, the Navy realized that the analog data processing and tactical systems being used by the SSBNs are not only difficult to maintain and operate, but also unsustainable by the end of FY 2018 due to spare parts and other equipment.

Pappano decided to bring the Navy's SSBNs to an open architecture electronic system called the Submarine Warfare Federated Tactical System (SWFTS) through regular hardware and software updates. Attack submarines and guided missiles - including four SSBNs
She entered Norfolk Navy Yard last month for mid-life engineering refueling operations, a 27-month period that will be filled with both scheduled work on the class maintenance plan and initiatives to keep the ship ready and relevant. Half of 42 years.
The SWFTS equipment upgrade will "simpler logistics, easier to maintain" for warships and operators, and "bring greater capability to the ship, essentially giving it a suite of tactical systems for an attack submarine," Pappano said. During refueling, the control room, computer station, sonar and other major components are removed from the sub and new computer servers and other equipment are installed. This will give the Navy the opportunity to establish Combined Fleet Network and Enterprise Services (CANES) – one of the Navy's major modernization efforts is trying to schedule all ships in the fleet, which will make SSBNs relevant and simple. To maintain and improve your service end of life.
, will receive SWFTS and CANES upgrades during mid-life refueling as the fourth smallest SSBN. Older boats can receive these upgrades during the second engineering overhaul period (ERP), which is 32 years in service, or the work can be scheduled at a later time when public carriers can handle the work and shipmasters are not needed.

(SSBN-730) will be the first to enter the 32-year mark of ERP later this year – another reminder of the importance of designing, building and deploying new ballistic missile submarines on time.
"Forty-two years ago, we had never worked with a submarine," Pappano said. When are SSBNs ready for use?
"We don't have a swing room that's been going on for over 42 years now. That's my position and I stand by it," Pappano said.

Through the house HMA and E, some of the work being done today is predicted by the analysis - replacing pipelines in steam plants, replacing analog computers and protecting the shell, for example Pappano. The Navy is reevaluating its plan to overhaul the Ohio-class boats every few years "to make sure we're investing modernization dollars in the right systems."
"SSGNs have been the canaries in the coal mine for us," Pappano said. These four boats are used in coastal areas rather than oceans, run at high speeds and on the surface, and land more frequently than their SSBN counterparts, creating "rapid aging of the platform".
"We can learn two things from the SSGN operations ahead of the SSBNs," he said, adding that the SSGN has already seen deterioration and damage to sanitary pipelines and decommissioning and drainage systems used to maintain neutral buoyancy. Maintenance or replacement of these systems by SSBNs is possible in the future.
Pappano said the Navy has a good handle on what they know they need to do to keep the SSBNs afloat, but noted that as the boats are late in their 42nd year, "some unknowns may emerge."

"My biggest concern is that I've never hugged because it hasn't come and bit me," he said. He said the Navy has prioritized maintenance and modernization efforts due to the strategic importance of the Ohio class and hopes that financial support will continue through the budget process. The Ohio class nuclear powered submarines include the US Navy's 14 ballistic missile submarines. (SSBNs) and four cruise missile submarines (SSGNs). Displacing 18,750 tons each, the Ohio-class submarines are the largest submarines ever built for the US Navy. They are the world's third largest submarine, after the Russian Navy's Soviet-designed 48,000-ton Hurricane.
With 24 Triad 2 missiles, Ohio-class submarines carry more missiles than Borei-class (16, 20 on Borei II) or Typhoon-class (20).
The Ohio-class SSBNs are part of the United States' nuclear-defense triad, along with the U.S. Air Force's strategic bombers and intercontinental ballistic missiles.
Together, the 14 SSBNs carry half of America's active strategic thermonuclear warheads. However, Trident missiles do not have pre-determined targets for patrolling submarines.
Why Russia Fears The Us Navy's Ohio Class Submarines
The flagship of this class is the USS Ohio. Harry M. from the USS. All Ohio-class submarines except Jackson were named for American states, a US Navy tradition previously reserved for battleships and cruisers. Starting in 2031, the Ohio section should be gradually replaced by the Columbia section.
Ohio-class submarines are designed for extended strategic defense patrols. Each submarine has two full crews, called the blue crew and the gold crew, each serving 70 to 90 days on patrol duty. Three large logistics hatches have been installed to provide large-diameter resupply and repair services to reduce personnel turnover and recovery time at the port. These hatches quickly accommodate pallets, equipment replacement modules, and machinery assemblies, re-acceleration and maintenance on the submarine. Furthermore, the submarines' "stealth" capabilities are greatly improved over previous ballistic missile submarines. In 1982, Ohio was unmatched in her sea trials, giving the US Navy great flexibility.
The design of the unit allows the boat to operate for approximately 15 years between major repairs. These submarines were reported to be as quiet as the earlier Lafayette-class submarines at a cruising speed of 20 knots (37 km/h; 23 kph) or 6 knots (11 km/h; 6.9 kph), although exact information remains. . assigned
Ohio-class submarines were constructed of hull sections, each four-story section 42 feet (13 m) in diameter.

Components were manufactured at the General Dynamics Electric Boat facility, Quonset Point, Rhode Island, and assembled at the shipyard in Groton, Connecticut.
The US Navy has a total of 18 Ohio-class submarines, including 14 ballistic missile submarines (SSBN) and four cruise missile submarines (SSGN). SSBN submarines form the naval base of the US nuclear triad. Each SSBN submarine is armed with up to 24 Trident II submarine-launched ballistic missiles (SLBM). Each SSGN can fire up to 154 Tomahawk cruise missiles, as well as Harpoon missiles in torpedo tubes.
The Ohio section was designed in the 1970s. The first eight Ohio-class submarines were initially armed with 24 Tridt I C4 SLBMs.
Starting with the ninth Tridt submarine, the remaining submarines were armed with the larger three-stage Trid II D5 missile.
