USS Ohio (SSBN-726)

USS Ohio (SSBN-726) is the lead vessel of the Ohio-class submarine, a class of nuclear-powered ballistic missile submarines (SSBNs) operated by the United States Navy. Commissioned in 1981, it was originally designed to carry Trident I (C-4) submarine-launched ballistic missiles as a cornerstone of the U.S. nuclear triad during the Cold War. Following the Strategic Arms Reduction Treaty, the submarine underwent a major conversion to become a guided missile submarine (SSGN), capable of carrying up to 154 Tomahawk cruise missiles and supporting special operations forces.

Construction and commissioning

The contract for the vessel was awarded to General Dynamics Electric Boat in Groton, Connecticut, on 1 July 1974. The keel was laid down on 10 April 1976 in a ceremony attended by officials including Admiral Hyman G. Rickover. The submarine was launched on 7 April 1979, sponsored by Annie Glenn, wife of Senator and former Mercury astronaut John Glenn. After extensive sea trials in the Atlantic Ocean, USS Ohio was commissioned into the United States Navy on 11 November 1981, with Captain Albert L. Kelln as its first commanding officer. The commissioning ceremony was held at Naval Submarine Base New London.

Design and capabilities

As the first Ohio-class submarine, it introduced a revolutionary design for the United States Navy's strategic deterrent force. Its primary armament consisted of 24 launch tubes for Lockheed-built Trident missiles, significantly more than the preceding Benjamin Franklin-class submarine. Powered by a General Electric S8G pressurized water reactor, the submarine could operate submerged for decades-limited only by food supplies and crew endurance. The vessel's HY-80 steel hull and advanced sonar suite, including the AN/BQQ-6 system, provided exceptional quieting and detection capabilities, crucial for evading Soviet Navy anti-submarine warfare forces. Its Ship's Deterrent Patrols were a key component of the Nuclear deterrence strategy articulated in documents like the Single Integrated Operational Plan.

Service history

Following commissioning, USS Ohio conducted its first deterrent patrol in 1982, operating from its home port at Naval Submarine Base Bangor in Washington. Throughout the 1980s, it completed numerous patrols in the Pacific Ocean and the Bering Sea, maintaining a constant at-sea presence as part of the United States Strategic Command. In 1986, the submarine began refitting to carry the more advanced Trident II (D-5) missile at Puget Sound Naval Shipyard. A notable incident occurred in 1994 when it collided with the Nigerian freighter MV Bonga in the Strait of Juan de Fuca, sustaining minor damage. Its service continued through the post-Cold War era, supporting operations during the Gulf War and the War in Afghanistan.

Ohio-class lead ship

As the lead ship, USS Ohio established the design and operational template for the most powerful class of ballistic missile submarines ever built for the United States Navy. The success of its design validated strategic concepts developed by the RAND Corporation and the Office of the Chief of Naval Operations. The class directly replaced the aging James Madison-class submarine and became the backbone of the sea-based leg of the U.S. strategic forces. The construction program, managed by Admiral Kinnaird R. McKee, was critical to maintaining parity with the Soviet Typhoon-class submarine under the terms of the SALT II treaty. The class's reliability influenced subsequent naval treaties, including START I.

Decommissioning and conversion

In compliance with START I treaty limits, USS Ohio concluded its final strategic deterrent patrol in 2002 and was officially decommissioned as an SSBN on 11 February 2005 at Puget Sound Naval Shipyard. Immediately following, it began an unprecedented conversion into a guided missile submarine (SSGN) under a program led by Northrop Grumman and General Dynamics. Twenty-two of its Trident missile tubes were reconfigured to launch canisters containing up to seven Tomahawk missiles each, while two tubes were converted to host Dry deck shelters for Navy SEALs from Naval Special Warfare Group. The converted submarine was recommissioned as SSGN-726 on 7 October 2006. It now serves with the United States Pacific Fleet, providing a massive conventional strike and special operations capability, notably supporting exercises like RIMPAC and operations in the U.S. Central Command area of responsibility.
