The Sprint was a two-stage, solid-fuel anti-ballistic missile (ABM), armed with a W66 enhanced-radiation thermonuclear warhead used by the United States Army during 1975–76. It was designed to intercept incoming reentry vehicles (RV) after they had descended below an altitude of about 60 kilometres (37 mi), where the thickening air stripped away any decoys or radar reflectors and exposed the ...
The Sprint missile was the main weapon in the Nike-X system, intercepting enemy ICBM warheads only seconds before they exploded. Nike-X was an anti-ballistic missile (ABM) system designed in the 1960s by the United States Army to protect major cities in the United States from attacks by the Soviet Union's intercontinental ballistic missile (ICBM) fleet during the Cold War.
The Sprint missile was the main weapon in the Nike-X system, intercepting enemy ICBM warheads only seconds before they exploded. Nike-X was a proposed US Army anti-ballistic missile (ABM) system designed to protect major cities in the United States from attacks by the Soviet Union's ICBM fleet. The name referred to its experimental basis, it ...
The missile's long range allowed protection of a large geographic area. If the Spartan failed to intercept the incoming offensive missile, the high performance and high speed but short ranged Sprint missile would attempt an interception within the atmosphere. Both missiles used nuclear warheads, and they relied on destroying or damaging the ...
The Stanley R. Mickelsen Safeguard Complex (SRMSC) was a cluster of military facilities near Nekoma, North Dakota, that supported the United States Army's Safeguard anti-ballistic missile program. [1] The complex provided launch and control for 30 LIM-49 Spartan anti-ballistic missiles, and 70 shorter-range Sprint anti-ballistic missiles.
Intercept: Most systems can be used in different phases of ballistic missile flight, i.e., boost [73] (where surface or air-launched anti-aircraft missiles might also be effective because the ballistic missile is moving relatively slowly at low altitude), requiring proximity to the launch site and immediate response, mid-course/exo-atmospheric ...
To explore whether such a system was possible, ARPA and the U.S. Army Missile Command funded development of HiBEX with Boeing as the prime contractor, and Hercules supplying the new solid rocket motor. [22] HIBEX was essentially a smaller version of the Sprint concept, about 16 feet (4.9 m) long and 3.6 feet (1.1 m) in diameter.
The LIM-49 Spartan was a United States Army anti-ballistic missile, designed to intercept attacking nuclear warheads from intercontinental ballistic missiles at long range and while still outside the atmosphere.
