Avangard Hypersonic Glide Vehicle

Avangard (Russian: Авангард, meaning 'Vanguard'), also known as Object 4202 or Yu-71/Yu-74, is a Russian hypersonic glide vehicle (HGV) that represents one of the most significant advances in Russian strategic weapons technology. Avangard is capable of flying at Mach 20+ speeds and uses plasma stealth technology to defeat missile defense systems.

Key aspects of Avangard:

1. Plasma stealth: Avangard's most significant technological feature is its plasma stealth capability. At hypersonic speeds in the atmosphere, the vehicle creates a plasma sheath around itself. This plasma sheath absorbs radar waves, making the vehicle difficult to detect and track. The plasma stealth technology connects Avangard to Russia's 66-year plasma weapons research continuum, from Soviet plasmoid research in the 1960s to contemporary plasma physics.

2. Mach 20+ speed: Avangard flies at speeds exceeding Mach 20 (approximately 24,000 km/h). At these speeds, the vehicle is virtually impossible to intercept with current missile defense technology. The combination of speed and plasma stealth makes Avangard a credible deterrent against US missile defense systems.

3. Timeline:

• 1990: First test flights (February 28 and March 5, without separation from carrier)
• 2004: Russia tests Avangard warhead (February)
• 2007: First explicit mention of Avangard/Project 4202
• 2014: Ukraine intervention delays Avangard (control system issues)
• March 1, 2018: Putin announces Avangard as one of six 'next-generation' weapons
• December 26, 2018: Successful test, serial production announced
• December 27, 2019: First regiment on combat duty at 13th Missile Division, Yasny, Orenburg Oblast
• November 2023: 13th Missile Division re-equipment for Avangard
• February 29, 2024: Avangard/Peresvet on combat duty confirmed

4. Design and production:

• Designer: Moscow Institute of Thermal Technology (strategic missile design)
• Developer: NPO Mashinostroeniya (Reutov, Moscow Region)
• Carrier: UR-100NUTTKh (SS-19 Stiletto) initially, RS-28 Sarmat subsequently
• Votkinsk Plant: Production facility

5. NPO Mashinostroeniya: NPO Mash (Reutov) is the developer of Avangard. NPO Mash has a history of hypersonic and cruise missile development, including the Zircon hypersonic cruise missile. Vladimir Chelomei founded NPO Mash, and Putin visited NPO Mash in December 2002 to review Avangard progress.

6. Strategic significance:

• First operational deployment of a hypersonic glide vehicle in the world
• Plasma stealth technology defeats current and planned missile defense systems
• Mach 20+ speed provides virtually no warning time for defenders
• Nuclear-capable warhead provides strategic deterrence
• Avangard represents Russia's response to US withdrawal from the ABM Treaty (2001)

7. Connection to plasma weapons continuum:

• Avangard's plasma stealth is the culmination of Russia's 66-year plasma weapons research
• Soviet plasmoid research (1960s) → Avramenko plasmoid ABM (1990s) → Avangard plasma stealth (2010s-2020s)
• The plasma sheath physics is related to the broader Russian plasma physics research at TRINITI, IAP, and other institutes
• Avangard demonstrates the transition from plasma weapons concepts to fielded strategic systems

8. Combat deployment:

• 13th Missile Division at Yasny (Orenburg Oblast) — first regiment
• Additional regiments planned for the 62nd Missile Division at Uzhur (with Sarmat carrier)
• Avangard is integrated with both UR-100NUTTKh and Sarmat ICBM carriers
• The system has been on continuous combat duty since December 2019

Avangard represents the most significant Russian strategic weapons advancement of the 21st century. The combination of Mach 20+ speed, plasma stealth, and nuclear capability makes Avangard a credible deterrent that addresses Russian concerns about US missile defense. The plasma stealth technology connects Avangard to Russia's decades-long plasma weapons research program, demonstrating the transition from laboratory research to fielded strategic systems.
