The Indian Air Force's plans to equip the Su-30MKI with long-range R-37M missiles are not related to replacing the Astra Mk2; it is a completely different class of weapon. Military analyst Raunak Kunde of IDRW agency explained the essence of the upcoming deal.
He noted that the R-37M is significantly larger than conventional long-range air-to-air missiles. Its mass is about 510 kg, diameter is 380 mm, and warhead is about 60 kg. Its main targets are considered to be tankers and AWACS aircraft.
The Su-30MKI is suitable for the R-37M due to its high payload capacity and aircraft size. At the same time, the Indian Astra Mk2 program will continue. The missile is already associated with tests on the Su-30MKI and plans for a large purchase after the completion of tests.
Kunde added that the Astra Mk2 solves a different problem – hitting fighters beyond visual range. Therefore, India can use the two missiles not as competing, but as complementary systems.
It should be recalled that the main carrier of the R-37M in the Russian Aerospace Forces is the Su-35S, the acquisition of which India officially refused. Instead, the republic plans to modernize its Su-30MKI fleet and is simultaneously considering new Su-57s.
