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 W76-0 was fitted inside a Mk4 reentry vehicle (reentry body in US Navy parlance) while the W76-1 and -2 are fitted inside the new Mk4A reentry vehicle. Reentry vehicle and warhead weight is estimated to be approximately 95 kilograms (209 lb).
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 ...
The Avangard (Russian: Авангард, "Vanguard"; previously known as Objekt 4202, Yu-71 and Yu-74) is a Russian hypersonic glide vehicle (HGV). It can be carried as a multiple independently targetable reentry vehicle (MIRV) payload of heavy intercontinental ballistic missiles (ICBMs), such as the UR-100UTTKh, [6] [7] R-36M2 and RS-28 Sarmat.
The exact dimensions of the W87 are classified, but it fits inside the Mk. 21 reentry vehicle, which is a cone with base diameter of 22 inches (56 cm) and a length of 69 inches (180 cm). The weight is believed to be between 440 and 600 pounds (200 and 270 kg). [4] The reentry vehicle Mk21 is stored and transported in an H1473 container. [5] [6]
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 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]
