R-37M Missile:

In a major development for India’s air superiority, Moscow recently greenlit the sale of its formidable R-37M ultra-long-range air-to-air missile to New Delhi.
- The R-37M missile, known by its NATO reporting name AA-13 Axehead, is a long-range air-to-air missile developed by Russia.
- It is designed to eliminate enemy fighter jets and drones beyond visual range (BVR).
- People often call the R-37M an “AWACS Killer” because it can go after large and important enemy aircraft. These include radar planes like AWACS, refuelling tankers, and even jamming aircraft that help enemy fighters.
- Indian engineers expect the missile to fit smoothly onto the IAF’s Su-30MKI fighters because the weapon is already approved for the Russian Su-30SM, which is almost the same type of aircraft.
- R-37M carries a 60-kilogram high-explosive fragmentation warhead intended for large airborne targets.
- Its guidance architecture combines inertial navigation, mid-course data-link updates, and active radar homing during the terminal phase, allowing the launching aircraft to adjust targeting information dynamically.
- It also employs a lofted trajectory profile, enabling the missile to climb before descending toward its target, thereby conserving energy and extending effective engagement range.
- It features a jettisonable rocket booster that allows it to achieve a range of 300 to 400 kilometers, making it one of the longest-reaching air-to-air missiles in service globally.
- Its speed can reach hypersonic levels, up to Mach 6, which is crucial for intercepting fast-moving targets. It is the world’s fastest known air-to-air missile class.
