TRIDENT, named for the three pronged spear (TRIDENT) of mythology's King Neptune is the Navy's third generation fleet ballistic missile program. It is a part of the Nation's strategic deterrent triad, which also includes land-based missile systems and manned bombers.

The TRIDENT I, or C-4 missile, represents a quantum leap in technology and capability of the fleet ballistic missile (over the POLARIS/-POSEIDON predecessors). The missile has a range of more that 4,000 nautical miles, more that 1,500 nautical miles greater than POLARIS.
