#DidYouKnow Submarine Missiles: Soon after the second world war, the work on concept of a submarine launched missile began. The U.S Navy's first fleet ballistic missile, the Polaris A-1, had a range of 1400 nautical miles, with a single 600 kiloton warhead, and today, the Trident II D5 missile has a range of 6,500 nautical miles, and carries 8 to 14 warheads. | Naval Submarine School
