This taken from: http://www.whatreallyhappened.com/trinitite.html gives a good brief overview on just what power the US Military has at its disposal. Included also is a brief synopsis of the M.A.D. policy the USA & late USSR used which worked well back then in preventing WWIII.
The US spent $5 trillion dollars (1950s dollars) building a nuclear deterrent capability that can actually melt any nation and it's people into a giant slab of green glass. The USSR knew it, the world knows it, Saddam knew it. The government of Iran knows it.
....The [Ohio class] submarine has the capacity for 24 Trident missile tubes in two rows of 12. The dimensions of the Trident II missile are length 1,360cm x diameter 210cm and the weight is 59,000kg. The three-stage solid fuel rocket motor is built by ATK (Alliant Techsystems) Thiokol Propulsion. The US Navy gives the range as "greater than 7,360km" but this could be up to 12,000km depending on the payload mix. Missile guidance is provided by an inertial navigation system, supported by stellar navigation. Trident II is capable of carrying up to twelve MIRVs (multiple independent re-entry vehicles), each with a yield of 100 kilotons, although the SALT treaty limits this number to eight per missile. The circle of equal probability (the radius of the circle within which half the strikes will impact) is less than 150m. The Sperry Univac Mark 98 missile control system controls the 24 missiles.
The 14 Trident II SSBNs carry together around 50 percent of total U.S. strategic warheads. (The exact number varies in an unpredictable and highly classified manner below a maximum set by various strategic arms limitation treaties.) Although the missiles have no pre-set targets when the submarine goes on patrol, the SSBNs are capable of rapidly targeting their missiles should the need arise, using secure and constant at-sea communications links. The Ohio class are the largest submarines ever built for the U.S. Navy, and are second only to the Russian Typhoon class in mass and size. A single submarine carries the destructive power more than nine times greater than all Allied ordnance dropped in WWII.....
