English: The only one of its kind to be on public display, a Poseidon C-3 missile with all of its electronics, hydraulics and propulsion elements still intact, is on display for visitors to examine at USS Bowfin Submarine Museum & Park. This massive cutaway mock-up weighs 12,000 pounds, is 34 feet long and is 74 inches in diameter. The C-3 strategic missile was capable of being launched from a submerged Fleet Ballistic Missile submarine. The first submarine to carry and launch a C-3 missile was USS James Madison (SSBN-627) in August of 1970. The missile was donated to the Museum by the U.S. Navy through Lockheed Missiles and Space Company, which manufactured the C-3 missiles for the Navy. See also: en:UGM-73 Poseidon
