![]() ![]() Two classes of the Russian Navy's submarines have larger total displacements: the Soviet-designed Typhoon-class submarines have more than twice the total displacement, and the Russian Federation's Borei-class submarines have roughly 25 percent greater displacement, but the Ohio-class warships carry more missiles and warheads than either of the other designs: 24 Trident missiles per boat, versus only 16 missiles for the Borei class (20 for the Borei II) and 20 for the Typhoon-class. The Ohio-class submarines are the largest submarines ever built for the U.S. states, which until that point was a tradition reserved for battleships and cruisers. Although the Trident missiles have no pre-set targets when the submarines go on patrol, the warships, when required, are capable of quickly being assigned targets by using secure and constant radio communications links at sea, including very low frequency (VLF) systems.Īll the Ohio-class submarines, except for the USS Henry M. The exact number of warheads deployed in the oceans of the world varies in an unpredictable and classified manner, always at or below a maximum number set by various Strategic Arms Reduction Treaties. The 14 Trident II SSBNs together carry approximately fifty percent of the total US active inventory of strategic thermonuclear warheads. The Ohio class is named after the lead submarine of this class, USS Ohio. The Navy has 18 Ohio-class ballistic missile submarines (SSBN) and guided missile submarines (SSGN). The Ohio class is a class of nuclear-powered submarines used by the United States Navy. General characteristics SSBN-734 and subsequent hulls upon construction, SSBN-730 to SSBN-733 since refuelingĢ4 × Trident II D5 SLBM with up to 12 MIRVed W76 or W88 (300–475 kt TNT) nuclear warheads each, range 6,500 nmi (12,000 km 7,500 mi)Ģ2 tubes, each with 7 Tomahawk cruise missiles, totaling 154 General characteristics SSBN-726 to SSBN-733 from construction to refuelingĢ4 × Trident I C4 SLBM with up to 8 MIRVed 100 kt TNT W76 nuclear warheads each, range 4,000 nmi (7,400 km 4,600 mi) Navy. However, because the first few Ohio-class strategic nuclear submarines have been in service for a long time and their hulls are aging, they are no longer able to undertake the mission of strategic nuclear deterrence. Therefore, the first four ships of the Ohio-class strategic nuclear submarine have been converted into cruise missile nuclear submarines carrying conventional guided missiles.ĭon’t look at the obvious gap between the United States and Russia in the development of land-based intercontinental missiles, but it does not mean that the United States does not have the ability and level to develop land-based intercontinental missiles, and even strategic missile nuclear submarines and submarine-launched ballistic missiles with more demanding technical requirements are Land-based nuclear weapons with relatively low technical requirements that can be easily developed are not a problem for the United States, but the strategic focus of the United States and Russia is different.The USS Michigan (SSBN-727) at a drydock, in November 2002.ġ6,764 tonnes (16,499 long tons) surfaced ġ8,750 tonnes (18,450 long tons) submerged Ģ× geared turbines 60,000 shp (45 MW) Fairbanks Morse auxiliary diesel Ģ0 knots (37 km/h 23 mph) submerged (official) Ģ5 knots (46 km/h 29 mph) submerged (reported) īQQ-6 passive bow-mounted array (which includes BQS-13 fire control array) Ĥ × 21 in (53 cm) Mark 48 torpedo tubes (midships) ![]() Currently, a total of 18 Ohio-class nuclear submarines are in service with the U.S. Equipped with a 24-tube SLBM vertical launch system.
