Project 4202

Intelligence Summary: Project 4202 — Avangard Hypersonic Glide Vehicle Development Program

Node Identity Project 4202 (also known as Objekt 4202, Yu-71, Yu-74) is the classified development program for Russia's Avangard hypersonic glide vehicle (HGV). Development began in 2004 under NPO Mashinostroeniya, with approximately 14 reported flight tests between 1990 and 2018. The program culminated in the deployed Avangard system revealed by Putin in March 2018, with the first regiment entering combat duty on December 27, 2019.

Strategic Relevance Project 4202 represents the operationalization of decades of Russian plasma physics research into a deployed strategic weapons system. The program's direct lineage from the 1980s Albatross program — which focused on solving plasma-related stealth, guidance, and radio wave propagation problems for glide re-entry vehicles — makes it the longest-running documented Russian plasma weapons development effort. The Avangard system it produced is the most advanced and operationally mature of Russia's six "super weapons" announced in 2018. As of May 2025, 12 Avangard-equipped UR-100N UTTH ICBMs are deployed with the 13th Red Banner Rocket Division at Yasny, Orenburg Oblast. The system achieves Mach 20-27 speeds with intercontinental range (>6,000 km), carrying a nuclear warhead (2 MT option reported). Putin described it as "a technological breakthrough comparable to the 1957 Soviet launch of the first satellite."

Technical Focus / Capabilities Project 4202 developed a nuclear-capable hypersonic boost-glide vehicle that separates from its booster at ~100 km altitude and glides through the atmosphere to its target. Key technical achievements include: (1) advanced composite materials capable of surviving 1,600-2,000°C surface temperatures, (2) flight control systems operable "amid plasma" — solving the communications blackout problem that plagues all hypersonic vehicles, (3) unpredictable maneuvering capability to defeat missile defenses, and (4) kinetic energy at speed equivalent to ~21 tons of TNT (excluding warhead). The 2014 loss of Ukrainian-manufactured control components forced a domestic substitution program, demonstrating the program's dependence on specific industrial supply chains.

Network Linkage Project 4202 is the precursor to the Avangard Hypersonic system, developed by NPO Mashinostroeniya, with its own precursor in the Albatross Project. TsNIIMash provides oversight. The program connects to the Putin 2018 Address (where it was publicly revealed) and to the Plasma Stealth and Mach 20 Flight concept nodes through its operational capabilities.
