Lists on the subject |
The UGM-73 Poseidon was the second generation of sea-based ballistic missiles in the United States , successor to the UGM-27 Polaris and predecessor to the Trident . It was launched from strategic nuclear submarines .
The two-stage solid rocket was a further development of the Polaris missile. The omission of guide tubes and sealing rings in the launch tube made it possible to use a missile that was 51 cm in diameter. With the same range as the Polaris, the Poseidon had twice the payload with greatly increased accuracy and, in contrast to the Polaris SLBM, could use multiple warheads (MIRV) .
The first flight took place in 1968, the first underwater take-off in August 1970 from the USS James Madison (SSBN-627) . Shortly thereafter, the Lafayette-class submarines were equipped with Poseidon missiles.
