Ohio-class Submarine

==Summary==
The Ohio class of nuclear-powered submarines is the sole class of ballistic missile submarines (SSBN) currently in service with the United States Navy. Fourteen of the eighteen boats are SSBNs, which, along with U.S. Air Force strategic bombers and intercontinental ballistic missiles, constitute the nuclear-deterrent triad of the U.S. The remaining four have been converted from their initial roles as SSBNs to cruise missile submarines (SSGNs). The Ohio-class boats, each displacing 18,750 tons submerged, are the third largest submarines in the world, behind the 48,000-ton Typhoon class and 24,000-ton Borei class of the Russian Navy. The Ohio class replaced the Benjamin Franklin- and Lafayette-class SSBNs.

==Powers and Stats==
Tier: with Mark 48 torpedoes and Tomahawk missiles (conventional); At least , possibly with Trident SLBM
Name: Ohio-class submarine
Origin: The Real World
Age: 1981–present
Classification: Nuclear submarine, Ballistic missile submarine
Length: 170 meters (560 feet)
Beam: 13 meters (42 feet)
Draft: 10.8 meters (35.5 feet)
Displacement: 16,764 tonnes (16,499 long tons) surfaced; 18,750 tonnes (18,450 long tons) submerged
Pilot(s): 15 officers, 140 enlisted
Needed Prerequisite for Use: Trained crew, fuel, ammunition
In use by: United States Navy
Powered by: One S8G PWR nuclear reactor, two geared turbines with 60,000 shp (45 MW) Fairbanks Morse auxiliary diesel; one 325 hp (242 kW) auxiliary motor; one shaft with seven-bladed screw
Operational Timeframe: Practically limited only by food supplies
Terrain: Ocean (surface and submerged with a test depth of 240 m)
Material: Unknown. Likely hardened armor-grade steel.
Attack Potency: Building level with Mark 48 torpedoes (0.29 ton explosives) and conventional Tomahawk missiles (up to 0.45 ton TNT), at least Large Town level, possibly Small City level+ with various Trident SLBM
Speed: Normal Human travel speed (12 knots; 22 km/h; 14 mph; 6.2 m/s) when surfaced; at least Peak Human travel speed (20 knots; 37 km/h; 23 mph; 10.28 m/s) submerged, possibly faster
Durability: At least Large Building level, at most Multi-City Block level in terms of total destruction (comprised of up to 16,764,000 kilograms of hardened armor-grade steel with likely a fragmentation energy of over 1.59 terajoules or 380 tons of TNT)
Range: Estimated operational range of: 50 km (31 mi; 27 nmi) at 40 kn (74 km/h; 46 mph) or 40 kn (74 km/h; 46 mph) with Mark 48 torpedo; up to over 1300 km with Tomahawk missiles (conventional); over 7,400 km (4,000 nmi; 4,600 mi) with Trident I C4 SLBM; over 11,300 km (6,100 nmi; 7,000 mi) with Trident II D5 SLBM
Weaknesses: Typical submarine weakness. Mainly designed to be deploying nuclear warheads instead of fighting other submarines and moving warships.
Weaponry:
*4× 21 inch (533 mm) Mark 48 torpedo tubes (Forward Compartment 4th level)
Additional weaponry (General characteristics SSGN conversion):
*22 tubes, each with 7 Tomahawk cruise missiles, totaling 154
Additional weaponry (General characteristics SSBN-734 and subsequent hulls upon construction, SSBN-730 to SSBN-733 since refueling):
*24 × Trident I C4 SLBM with up to 8 MIRVed 100 kiloton TNT W76 nuclear warheads each
Additional weaponry (General characteristics SSBN-734 and subsequent hulls upon construction, SSBN-730 to SSBN-733 since refueling):
*24 × Trident II D5 SLBM with up to 12 MIRVed W76 or W88 (300–475 kiloton TNT) nuclear warheads each
Note: Similar ships of about the same type and period generally have performance equivalent to this one.
