Trident Facts (2014)1 (“~” means approximately – much of the actual numbers data is classified by most countries)

USS Henry M Jackson on Hood Canal

Number of US Trident submarines = 18 14 are armed with Trident II missiles (SSBN class). As of 2010 4 Trident subs were reconfigured as SSGN to carry up to 154 Tomahawk Cruise missiles (non-nuclear) or fewer missiles and other capacities in remaining missile tubes. Number of Trident II missiles per SSBN Trident = 24 Number of nuclear warheads Trident II missiles are designed to carry (as of 2005) = 14 Total number of warheads currently allowed on one Trident sub under New START treaty ~ 140 Total number of warheads currently assigned to the U.S. Trident fleet ~ 1,150 2,130 total operational nuclear warheads in the US arsenal Percentage of total U.S. nuclear warheads deployed on Trident fleet = 54% (1150 / 2130) Number of kilotons of TNT equivalent explosive power on one Trident W76 warhead ~ 100 kt Number of kilotons of TNT on one Trident W88 warhead ~ 475 kt Number of W88 warheads deployed on Trident fleet under New START = 240 Total number of kilotons deployed on Trident fleet under New START = 240 x 475 = 114,000kt = ….....114 megatons Number of kilotons on atomic bomb that was dropped on Hiroshima ~14 Number of people killed by the atomic bombing of Hiroshima ~ 150,000 Number of “Hiroshimas” each Trident is capable of destroying ~ 8,000 (240 x 475 / 14) Number of nuclear warheads deployed by the U.S. = 1920 (7,315 in the stockpile) 2 Number of warheads deployed by Russia = 1600 (~8,000 in the stockpile) Total nuclear warhead deployment of England, France, and China ~ 450 1 http://thebulletin.org/2014/january/us-nuclear-forces-2014 2 http://www.fas.org/issues/nuclear-weapons/status-world-nuclear-forces/

Number of nuclear warheads based in Kitsap County, Washington ~ 1,150 Number of US submarine-launched nuclear warheads allowed under the START II treaty = 240 Number of Trident missiles “needed” to deploy 240 warheads allowable under START II = 34 Number of Trident missiles currently deployed = 120 (~ 6 Trident subs are at sea at one time) Price of one Trident II D-5 missile: Sept 19/14: Production. Lockheed Martin Space Systems in Sunnyvale, CA receives a $146.3 million fixed-price-incentive, cost-plus-incentive-fee, and cost-plus-fixed-fee contract modification for new Trident II (D5) missile production, D5 Life Extension development and production, and D5 Deployed Systems Support. $37.3 million per missile3 Number of new Trident II D-5 missiles the Navy has purchased = 1084 Number of successful test flights of Trident missiles = 134 Number of Trident submarines needed to reach New START warhead deployment limits = 2 Number of Trident submarines the Navy wants to deploy indefinitely = 14 now with 12 replacements starting one per year in 2031. Price to operate one Trident submarine for one year = $50,000,000 (1996 figure) Planned service life of each Trident submarine = 42 years Total cost of the entire Trident program through year 2032 ~ $170 billion Cost estimate for triad nuclear weapons over 2014-2023 = $350 billion (Congressional Budget Office estimate)5 The Navy estimates the total 50-year lifecycle cost of the rebuilt Trident fleet at $347 billion.6 This estimate does not include upgrades on the Trident II missiles, warheads, satellite navigation systems, and command and control operations. Best guess total cost of triad modernization and deployment through the end of this century ….........................................................~ $1 trillion Climate model of a 100 Hiroshima-sized-atomic-bomb war between India and Pakistan: Global cooling for 5-10 years causing 10-40% reduction in staple food crops across South Asia and China where many are already food insecure, putting as many as 2 billion lives at risk of starvation.7
