Project history: These are by far the largest US submarines, although they are overshadowed by the Soviet Akulas. They differ from earlier US strategic submarines in having twenty-four rather than sixteen missiles, and incorporate a bow sonar (BQQ-6, similar to BQQ-5 but without active elements) and torpedo tubes set back from the bow, as in the newer attack submarines. The S8G reactor is a natural circulation type, related to the S5G in the Narwhal. Ohio class submarines were planned to operate 70-day patrols, with 25-day refit periods between patrols (shortened by the provision of special access trunks into the hull), with a 20-monih refit every nine years, for an overall force availability of 66%, compared to 55% of Poseidon submarines. Really deployment average is 77 days with 35 days in the homeport. Each submarine has two equal crews for year-round operations. The entire programme has suffered from severe delays. Ohio did not run trials until June 1981, although delivery was originally scheduled for December 1977.
Modernizations: 2002, Alaska; 2003, Nevada; 2005, Henry M. Jackson; 2008, Alabama: - 24 Trident C-4 SLBM (UGM-96A); + 24 Trident D-5 SLBM (UGM-133A)
12/2005, Ohio; 4.2006, Florida; 11.2006, Michigan; 11.2007, Georgia: were converted to cruise-missile submarines with data as given in the table.
