Flying at lower speeds than short-range ballistic missile warheads makes them easier to attack. [23] Those that approach with very low terminal attack profiles are even subject to attack by modern hypervelocity guns and railguns. [24] Hypersonics, like the Avangard HGV, generally use scramjet engines to achieve hypersonic speeds. Scramjet ...
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 DF-ZF is a hypersonic glide vehicle (HGV) developed by the People's Republic of China. It is launched by the DF-17 medium-range ballistic missile. The combined weapon system was likely operational by October 2019. [2] [3] The United States once referred to the DF-ZF as the WU-14. [1] The DF-17 was previously referred to as the DF-ZF. [2]
Hypersonic glide vehicle (HGV): missile warheads which maneuver and glide through the atmosphere at high speeds after an initial ballistic launch phase [3] [1] Hypersonic cruise missile: cruise missiles which use air-breathing engines such as scramjets to reach high speeds [ 3 ] [ 1 ]
On 28 June 2024, the DoD announced a successful recent end-to-end test of the US Army's Long-Range Hypersonic Weapon all-up round (AUR) and the US Navy's Conventional Prompt Strike. The missile was launched from the Pacific Missile Range Facility, Kauai, Hawaii, [13] landing more than 2000 miles away in the Marshall Islands. [7]
The DF-17 uses the rocket booster from the DF-16B short-range ballistic missile. [6] It is more difficult for missile defenses to intercept the manoeuvrable DF-ZF than a ballistic missile, whose trajectories are more predictable. [7] [5] DF-17 strikes to degrade air and missile defenses may precede the use of less survivable weapons. [5]
The Falcon HTV-1 program, which preceded the Falcon HTV-2 program, was conducted in April, 2010. The mission ended within nine minutes from launch. [5] Both these missions are funded by the US Defense Advanced Research Projects Agency to help develop hypersonic technologies and to demonstrate its effectiveness. [6]
The AGM-183 ARRW ("Air-Launched Rapid Response Weapon") is [5] a hypersonic air-to-ground ballistic missile planned for use by the United States Air Force.Developed by Lockheed Martin, the boost-glide vehicle is propelled to a maximum speed of more than Mach 5 [6] by a rocket motor before gliding toward its target.
