Drawing of the Mark 12 re-entry vehicle that houses the W62 warhead. The W62 was an American thermonuclear warhead designed in the 1960s and manufactured from March 1970 to June 1976. Used on some Minuteman III ICBMs, it was partially replaced by the W78 starting in December 1979, and fully replaced by W87 warheads removed from MX Peacekeeper ...
W78 warheads are contained inside the MK12-A reentry vehicles of the LGM-30G Minuteman III. Drawing of the Mark 12A re-entry vehicle that houses the W78 warhead. The W78 is an American thermonuclear warhead with an estimated yield of 335–350 kilotonnes of TNT (1,400–1,460 TJ), deployed on the LGM-30G Minuteman III intercontinental ballistic missile (ICBM) and housed in the Mark 12A reentry ...
4. About 180 seconds after launch, the third-stage thrust terminates and the post-boost vehicle (D) separates from the rocket. 5. The post-boost vehicle maneuvers itself and prepares for re-entry vehicle (RV) deployment. 6. While the post-boost vehicle backs away, the RVs, decoys, and chaff are deployed (this may occur during ascent). 7.
These were delivered in the Mark 12A reentry vehicle. A small, unknown number of the previous Mark 12 RVs were retained operationally, however, to maintain a capability to attack more-distant targets in the south-central Asian republics of the USSR (the Mark 12 RV weighed slightly less than the Mark 12A).

SWERVE started in the 1970s and culminated with a successful flight test in 1985, which demonstrated a sophisticated maneuvering reentry vehicle technology [2] and paved the way for the Advanced Hypersonic Weapon program's Alternate Re-Entry System in the early 2010s, [3] which was later developed into the Common-Hypersonic Glide Body ...
The warhead was initially manufactured from 1978 to 1987 and designed by Los Alamos National Laboratory.It was initially fitted to the Trident I SLBM system, but after the Rocky Flats plant where its successor the W88 was being made was shut down in 1989 after a production run of only 400 warheads, it was decided to transfer W76 warheads to Trident II.
The Trident missile is a submarine-launched ballistic missile (SLBM) equipped with multiple independently targetable reentry vehicles (MIRV). Originally developed by Lockheed Missiles and Space Corporation, the missile is armed with thermonuclear warheads and is launched from nuclear-powered ballistic missile submarines (SSBNs).
