Avangard (hypersonic glide vehicle)
Russian missile From Wikipedia, the free encyclopedia
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. It can deliver both nuclear and conventional payloads.[8][9][10] The Avangard is reportedly capable of travelling at re-entry speeds (over Mach 27 and close to Mach 30).[11]

History
Summarize
Perspective
According to Vladimir Putin, the US withdrawal from the ABM Treaty in 2002 forced Russia to start developing hypersonic weapons: "We had to create these [hypersonic] weapons in response to the US deployment of a strategic missile defense system, which in the future would be capable of virtually neutralizing, zeroing out all our nuclear potential".[12] In 2007, when asked about U.S. plans to deploy ballistic missile defenses in Europe, Putin mentioned that Russia was developing “strategic weapons systems of a completely different type that will fly at hypersonic speed and will be able to change trajectory both in terms of altitude and direction".[13]
In October 2016, a flight test was carried out using a R-36M2 heavy ICBM launched from Dombarovsky Air Base, reportedly successfully hitting a target at the Kura Missile Test Range. This was reportedly the first fully successful test of the glide vehicle.[14]
On 1 March 2018, Russian President Vladimir Putin in his presidential address to the Federal Assembly in Moscow announced that testing of the weapon is now complete and that it has entered serial production. This was further confirmed by the commander of the Strategic Rocket Forces, Colonel General Sergey Karakayev.[15]
On 19 September 2020, Herbert Yefremov, an Advisor for Science at the NPO Mashinostroyenia, was awarded the Order of St. Andrew for his contributions to the development of Avangard.[16]
Design
HGVs differ from traditional ballistic missile warheads by virtue of their ability to maneuver and operate at lower altitudes.[17] The combination of maneuverability and high speed poses significant challenges for conventional missile defense.[according to whom?] With the advantage again swinging toward attack, R. Jeffrey Smith speculates that weapons of this type will reignite the kind of arms race that dominated the Cold War era.[18]
According to open-source analysis by Janes Information Services, Avangard is a pure glide vehicle without an independent propulsion system.[19] When approaching a target, the glider supposedly is capable of sharp high speed horizontal and vertical evasive maneuvers in flight. [according to whom?]
The Avangard weighs about 2,000 kg and travels at Mach 20–27, giving it the equivalent of 21 tons of TNT in kinetic energy alone, excluding any explosive warhead.[20]
Operators
- Strategic Rocket Forces – The Strategic Rocket Forces are the only operator of the Avangard HGV. As of December 2023,[21][22] 11 Avangard-equipped UR-100N UTTHs are deployed with:
