Description
Development of the Izdeliye 172 began in 1991 as a long-range air-to-air missile program. The airframe was derived from the 9K37 Buk surface-to-air missile system. Development was suspended in the mid-1990s due to funding constraints but resumed in 2004 following a partnership agreement between Russia and India. The missile has been designated by several names, including KS-172 and K-100. Reports indicated the project was terminated by 2010, and although occasional claims of renewed activity have surfaced since, the missile has never been confirmed to have entered service.
The K-100 is designed to engage high-value aerial assets, including airborne early warning and control (AWACS) aircraft, tankers, maritime patrol aircraft, and electronic warfare platforms. The missile utilizes a solid-fuel tandem rocket booster and is capable of 12g maneuvers. Guidance is provided by mid-course inertial navigation, transitioning to active radar homing for the terminal phase. The seeker is an enlarged derivative of the 9B-1103M system. The missile is equipped with an adaptive high-explosive (HE) fragmentation warhead. Available configurations include versions with and without a rocket booster. Compatible launch platforms include the Su-27, Su-30, Su-35, and MiG-31BM.
The missile is operated by the Russian Air Force, where it is integrated into the MiG-31BM interceptor program. India entered an arrangement to fund development and license-produce the weapon for use on Su-30MKI fighters. There are no recorded instances of combat use.
