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.
The path of the reentry vehicle is the upper streak of light, with the booster tanks immediately below. Lights from the Kwajalein Atoll in the Pacific can be seen in the lower right corner. The Advanced Maneuverable Reentry Vehicle (AMaRV) was a prototype MARV built by McDonnell Douglas.
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.
Unit cost: US$70,000,000 (equivalent to $194,571,949 in 2023): Specifications; Mass: 87,750 kg 193,460 lb [3]: Length: 21.8 m 72 ft [3]: Diameter: 2.34 m 7.7 ft [3]: Warhead: Up to 11 Avco Mk21 re-entry vehicles each carrying a 300 kt W87-0 warhead (though in practice, only 10 were carried); or 12 GE Mk12A re-entry vehicles each carrying a 335–350 kt W78 warhead (never deployed) [4] plus decoys
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 ...
Here is a diagram showing that the diameter of the reentry vehicle is no more than 50.8 cm. [27] [28] The yield of the W62 is publicly believed to be 170 kilotonnes of TNT (710 TJ). [ 2 ] The W56 warhead on Minuteman III's predecessor had a yield of 1.2 megatonnes of TNT (5.0 PJ), [ 29 ] while its successor, the W78, has a yield of 330 to 350 ...
The UGM-73 Poseidon missile was the second US Navy nuclear-armed submarine-launched ballistic missile (SLBM) system, powered by a two-stage solid-fuel rocket.It succeeded the UGM-27 Polaris beginning in 1972, bringing major advances in warheads and accuracy.
The first PRIME vehicle was launched from Vandenberg AFB on 21 December 1966 atop an Atlas SLV-3 launch vehicle. This mission simulated a low Earth orbit reentry with a zero cross-range. The ballute deployed at 99,850 ft (30,434 m), though the recovery parachute failed to completely deploy. The vehicle crashed into the Pacific Ocean. [1] [2]
