The missile warhead detonated at 23:30 GMT on May 6, 1962, approximately 1.2 miles (2 km) from the designated target point, and at the target altitude of 11,000 ft (3,400 m). The detonation was successful and had the full design yield of the W47Y1 at approximately 600 kilotons. The shot was designed to improve confidence in the US ballistic ...
The US Army started their first serious efforts in the anti-ballistic missile arena when they asked the Bell Labs missile team to prepare a report on the topic in February 1955. The Nike team had already designed the Nike Ajax system that was in widespread use around the US, as well as the Nike Hercules that was in the late stages of ...
The system works by burying a number of high-yield warheads near the missile field below the anticipated flight corridor of approaching enemy reentry vehicles (warheads). ). Approximately five to ten minutes before the arrival of the enemy warheads, the dust defense warheads would be detonated, sending a cloud of dust high into the atmosph
A blast wave reflecting from a surface and forming a mach stem. The air burst is usually 100 to 1,000 m (330 to 3,280 ft) above the hypocenter to allow the shockwave of the fission or fusion driven explosion to bounce off the ground and back into itself, combining two wave fronts and creating a shockwave that is more forceful than the one resulting from a detonation at ground level.
The W71 nuclear warhead Warhead being lowered into the borehole. The W71 nuclear warhead was a US thermonuclear warhead developed at Lawrence Livermore National Laboratory in California and deployed on the LIM-49A Spartan missile, a component of the Safeguard Program, an anti-ballistic missile (ABM) defense system briefly deployed by the US in the 1970s.
With single-warhead missiles, one missile must be launched for each target. By contrast, with a MIRV warhead, the post-boost (or bus) stage can dispense the warheads against multiple targets across a broad area. Reduces the effectiveness of an anti-ballistic missile system that relies on intercepting individual warheads. [16]
He also said that Moscow and Washington continue to give each other a 24-hour warning of any planned test launch of intercontinental ballistic missiles and submarine-launched ballistic missiles.
Shot Frigate Bird of Operation Dominic I on 6 May 1962, was the only U.S. test of an operational submarine-launched ballistic missile (SLBM) with a live nuclear warhead (yield of 600 kilotons), at Christmas Island. In general, missile systems were tested without live warheads and warheads were tested separately for safety concerns.
