India is reportedly considering the acquisition of Russia’s R-37M long-range hypersonic air-to-air missile for its Su-30MKI fighter fleet—a development that could significantly alter the balance of air power in South Asia, particularly after the high-profile Operation Sindoor, which showcased India’s ability to strike deep into hostile territory.
The R-37M, also known by its NATO designation AA-13 Axehead, is among the most advanced beyond-visual-range (BVR) missiles globally. It boasts a remarkable range of 300–400 kilometers and can achieve speeds up to Mach 6 (approximately 7,400 km/h), making it capable of engaging high-value aerial targets such as AWACS, refuelling tankers, and enemy fighters from distances far beyond the reach of most current air-to-air missiles.
The missile is equipped with a sophisticated guidance system combining inertial navigation, mid-course updates, and active radar homing, allowing it to autonomously track and engage targets even in complex electronic warfare environments.

A key advantage of the R-37M is its ability to strike from stand-off distances, meaning Indian pilots could engage adversary aircraft—such as Pakistan’s F-16s or AWACS—without entering their detection or engagement zones. This capability could render Pakistan’s prized air surveillance and fighter platforms deeply vulnerable, as the R-37M’s range and speed far exceed those of Pakistan’s current AIM-120C AMRAAMs and Chinese-supplied PL-15 missiles. The missile’s 60 kg high-explosive fragmentation warhead and “fire-and-forget” functionality further enhance its lethality and survivability in contested airspace.
Russia’s offer reportedly includes not only the direct supply of the R-37M but also the possibility of local production in India under the “Make in India” initiative, potentially involving Hindustan Aeronautics Limited (HAL) facilities. This aligns with India’s broader push for defense self-reliance and would deepen its strategic partnership with Russia. However, integrating the R-37M onto the Su-30MKI would require significant upgrades to the aircraft’s radar and fire-control systems, as the missile’s maximum range exceeds the detection capabilities of the current Bars radar.
The operational history of the R-37M, including its use by Russian forces in Ukraine, demonstrates its deterrent value. It compels adversaries to abandon missions and take evasive action, underscoring its psychological and tactical impact.

How Will The R-37M Missile Change India’s Air Combat Strategy Against China And Pakistan
he induction of the Russian R-37M hypersonic air-to-air missile will fundamentally transform India’s air combat doctrine, especially in the context of its adversaries, China and Pakistan. With a range of 300–400 kilometres and speeds up to Mach 6, the R-37M enables Indian pilots to engage high-value enemy assets—such as AWACS, tankers, and frontline fighters—from well outside the reach of most current adversary missiles and radars. This leap in BVR capability allows India to strike first, often without entering enemy airspace or detection zones, dramatically increasing survivability and operational flexibility.
Countering China’s PL-15 And Pakistan’s F-16/J-10C Fleets
China’s PL-15 missile, deployed on J-10C fighters and now supplied to Pakistan, has set a new standard for BVR combat in the region, with reported kills at ranges exceeding 180 kilometres. However, the R-37M’s range and speed outclass even the PL-15, giving India a significant edge in long-range engagements. This advantage is particularly relevant given recent air battles where both sides relied heavily on BVR missiles, electronic warfare, and advanced radar systems, rather than traditional dogfighting.
