While mulling over the Prompt Global Strike program in 2003, the US Air Force and DARPA launched the FALCON Project to. The CAV was supposed to work as a conventional ballistic missile as well as a hypersonic reentry vehicle, but after two failed tests in 2010 and 2011, this project was shelved., a successor to the CAV. Unlike the spherical CAV, the HTV-2 was shaped like a wedge.
Though AHW failed to meet the expectations during the second test conducted by the Department of Defense in 2014, the final test conducted in 2017 using a scaled version of AHW turned out to be a success. In 2018 AHW was renamed as Common Hypersonic Glide Body . The Pentagon hinted that this would be deployed as the common hypersonic glide vehicle for the US Army, Navy, and AirForce.It is crucial to manage the atmospheric drag during the development of a hypersonic weapon.
At hypersonic speeds, this shock wave makes a very narrow-angle with the weapon’s direction of motion and almost hugs the weapon, forcing the high temperature chemically unstable air to come in close contact with the weapon’s surface. These factors threaten the weapon’s integrity and thus pose significant challenges for designing hypersonic missiles.
changing the direction of an object flying at hypersonic speed will use up an enormous amount of the object’s kinetic energy, in turn slowing the object down. , “Any maneuvers you make bleed off energy because you’re not powering the glider, so you have to be careful how many maneuvers you can make so you can manage the energy that’s in it to make sure you can get to the target you want to."
