India’s Su-30MKI Missiles: India is moving ahead with the reported purchase of nearly 300 Russian R-37M very-long-range air-to-air missiles for its Su-30MKI fighter fleet. Reports put the value of the deal at about $1.2 billion. The missile is known by the NATO name AA-13 “Axehead”. The weapons are expected to be added to the Su-30MKI over the coming months and years.
The deal comes as India looks to improve its long-range air combat ability. The Su-30MKI is the main fighter aircraft of the IAF and already carries a wide range of weapons. Adding the R-37M would give it a much longer-range air-to-air option than many missiles currently used on the aircraft.

What Makes The R-37M So Powerful?
The R-37M is not mainly meant for close-range dogfights. It was built to attack important aircraft such as airborne early-warning planes, refuelling tankers and electronic warfare aircraft. Taking out these aircraft can make it much harder for enemy fighters to detect targets and operate effectively.
The missile can reportedly reach very long distances depending on launch conditions. Some sources give figures of up to 300 to 400 km. Its actual combat range can be lower and depends on factors such as launch height, speed and the target. The missile can reach around Mach 6 and carries a 60 kg fragmentation warhead. It is about 4.06 metres long and weighs around 510 kg.
Its guidance system also helps it attack targets from far away. The missile can first use inertial navigation and receive updates during flight. Near the target, its own radar seeker can take over. This means the launching fighter does not have to keep guiding the missile all the way to the target.
Why India wants it for the Su-30MKI
The need for a longer-range missile has become more important as China and Pakistan continue to develop and acquire advanced air-to-air weapons. Missiles such as China’s PL-15 have already increased the distance from which fighter aircraft can threaten each other.
India is also developing its own long-range weapons, including newer versions of the Astra family. But those systems are still going through development and testing. The R-37M can provide the IAF with an available long-range capability while Indian programmes continue moving forward.

The missile is already used with Russian aircraft including the MiG-31 and several Sukhoi fighters. Giving it to India’s Su-30MKI would allow the IAF to use its large existing fighter fleet for very-long-range air combat missions.
The R-37M has also been used by Russian forces during the war in Ukraine. Reports about its use there have highlighted how long-range air-to-air missiles can force enemy aircraft to operate more carefully and stay farther away from dangerous areas.
