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.
Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of ...
The first known example was the Alpha Draco tests of 1959, followed by the Boost Glide Reentry Vehicle (BGRV) test series, ASSET [16] and PRIME. [17] This research was eventually put to use in the Pershing II's MARV reentry vehicle. In this case, there is no extended gliding phase; the warhead uses lift only for short periods to adjust its ...
Maneuvering reentry vehicles MARV (instead of symmetrically shaped warheads) induce lateral drag during reentry and hence strongly bend the trajectory, thus deceiving lower altitude interceptor systems that generally assume a straight decelerating trajectory and which have a limited terminal guidance maneuverability and course correction ...
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.
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 ...
