ICBM

any supersonic ballistic missile which has a range of 3500 nautical miles or more

An intercontinental ballistic missile, or ICBM, is a long-range (greater than 5,500 km or 3,500 miles)  ballistic missile typically designed for nuclear weapons delivery, that is, delivering one or more nuclear warheads. Due to their great range and firepower, in an all-out nuclear war,  submarine and land-based ICBMs would carry most of the destructive force, with nuclear-armed bombers the remainder.
