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. AMaRV had an entry mass of approximately 470 ...
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.
During the initial project definition, the US had begun exploring maneuverable reentry vehicles (MARVs), which were intended to avoid Soviet ABM defences by continually moving and thereby upsetting any pre-computed intercept course. ARPA decided to add another phase of study to consider a highly maneuverable second stage that could be used to ...
Hinz says the Fattah-1 appears to have a warhead on a “maneuverable reentry vehicle,” which enables it to make adjustments to avoid missile defenses during a short portion of its dive to its ...
It also includes footage of a ground test of the Fattah’s second stage thrust-vectoring engine nozzle, which can pivot to allow the missile’s maneuverable reentry vehicle (MARV) to, well ...
The underlying aerodynamic concepts have been used to produce maneuverable reentry vehicles (MARV), to increase the accuracy of some missiles like the Pershing II. More recently, the concepts have been used to produce hypersonic glide vehicles (HGV) to avoid interception as in the case of the Avangard.
Scramjet engines function only when the glide vehicle reaches mach 4.5. These engines are disengaged as the HGV enters the terminal phase of its flight. Failure to deactivate the engines would cause a catastrophic build up of heat in the vehicle as the atmosphere becomes denser during reentry, prematurely destroying the vehicle.
In 2014, the U.S. Navy reported that images that have appeared on the internet showed similarities of a DF-21D re-entry vehicle to the American Pershing II missile's RV, which was withdrawn from service in 1988. The Pershing II's RV weighed 1,400 lb (640 kg) and was fitted with four control fins to perform a 25-G pull-up after reentering the ...
