The Advanced Maneuverable Reentry Vehicle (AMaRV) was a prototype MARV built by McDonnell Douglas. Four AMaRVs were made and represented a significant leap in reentry vehicle sophistication. Three of the AMaRVs were launched by Minuteman-1 ICBMs on 20 December 1979, 8 October 1980 and 4 October 1981.
The concept has also been used to extend the reentry time for vehicles returning to Earth from the Moon, which would otherwise have to shed a large amount of velocity in a short time and thereby suffer very high heating rates. The Apollo Command Module also used what is essentially a skip re-entry, as did the Soviet Zond and Chinese Chang'e 5-T1.
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.
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 ...
Prior to the April 2024 test of Hwasong-16B with hypersonic glide vehicle (HGV), in January 2024 a variant of Hwasong-16B with maneuverable reentry vehicle (MaRV) was tested. The official name of this variant may be Hwasong-16A (Korean: 화성-16가; lit. Mars Type 16A), [19] but it has not been officially confirmed. [16] [20]
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]
