What is the Kh-101? Russia’s Air-Launched Stealth Cruise Missile, Explained

The Kh-101 is Russia’s most modern air-launched cruise missile, designed by the MKB Raduga design bureau and produced by the Smolensk Aviation Plant. Developed in the late 1990s as a low-observable replacement for the older Kh-55, the Kh-101 first entered limited service in 2012 and saw initial combat use against Syria in November 2015. Since February 2022, the Kh-101 has been Russia’s most-fired strategic stand-off weapon against Ukraine, with more than 2,000 rounds launched from Tu-95MS “Bear” and Tu-160 “Blackjack” strategic bombers based at Engels and Olenya airbases. A nuclear-armed variant, the Kh-102, exists with a stated yield of 250 kT.

Stealth design
The Kh-101 introduced low-observable design features to Russian cruise-missile inventory for the first time: faceted fuselage with reduced radar cross-section, recessed engine inlet, and absorbent paint coatings. Public estimates put its frontal RCS in the range of 0.01 m² – significantly lower than the legacy Kh-55 but still higher than the U.S. AGM-158 JASSM. The shaping was optimized to penetrate the radar coverage of S-300P/PMU and Patriot, the dominant tactical air defenses of the late 1990s.
Combat record
- 17 November 2015 – Syria. First combat use. Russian Tu-160 and Tu-95MS bombers launched Kh-101 strikes against Islamic State targets in Raqqa, the longest-range Russian air-launched cruise missile mission since the Soviet era.
- 2015-2017 – Syria. Sustained use against ISIS, with strikes from bombers staging through Iran and the Caspian.
- 2022-present – Ukraine. Primary Russian strategic stand-off weapon. By late 2025, Russian forces had launched more than 2,000 Kh-101s against Ukrainian targets, primarily energy infrastructure, command nodes and weapons-production facilities. Ukrainian intercept rates with NASAMS, Patriot PAC-3 and IRIS-T SLM have steadily climbed from ~50 percent in 2022 to 75-85 percent by 2024.
The Engels strikes
In December 2022, Ukrainian forces conducted long-range UAV strikes against Engels-2 airbase – Russia’s primary Tu-95MS staging base for Kh-101 missions, located 700 km inside Russia. Two Tu-95MS bombers were damaged, demonstrating the vulnerability of Russia’s air-launched strategic strike infrastructure to Ukrainian deep strikes. Russia has since dispersed Tu-95MS operations across multiple bases including Olenya in the Arctic.

Why Kh-101 matters
The Kh-101 is the centerpiece of Russia’s strategic stand-off strike doctrine against Ukraine. Its combination of long range, low observable shaping and dual-capable (conventional + nuclear) configuration makes it the Russian equivalent of the U.S. AGM-86 ALCM, with significantly larger production volume. As Russia continues to fire roughly 30-50 Kh-101 per month against Ukraine, the missile is shaping both Russian production priorities at Smolensk and NATO air-defense planning for the next decade.
