The Su-57 fighter jet, Russia’s fifth-generation aircraft, is set to be equipped with R-37M missiles, which are designed to strike high-speed targets at a range of over 300km.
The R37-M missiles are updated versions of former missiles which came into service in 1985.
The new model is in its final stages of development, and will feature a new guidance system, along with reduced weight and length in order to fit on the smaller Su-57 jets.
The former model was among the largest air-to-air missiles, measuring 4.2 metres in length and 600kg in weight.
Boris Obnosov, director of the Tactical Missiles Corporation (KTRV), confirmed this week the new missiles will be fired by the Su-57 aircraft.
Yuri Borisov, Russia’s Deputy Defence Minister, praised the combat capabilities of the jets.
He said: “The plane has proven to be very good, including in Syria, where it confirmed its performance and combat capabilities.
“The Su-57 is considered to be one of the best aircrafts produced in the world.”
The missiles will likely be carried externally due to their size, despite the vast majority of similar weapons being carried in internal bays in order to avoid detection in stealth missions.
The state-of-the art weapons will travel at speeds of Mach 6, and will have an active-seeker homing system, which will take over during the terminal phase.
They will consequently pose a serious threat to even the most advanced international fighter jets.
Strategic aircraft will also be targeted, including Airborne Warning and Control System (AWACS) aeroplanes, which provide radar detection of aircraft, ships and vehicles at long ranges and perform command and control duties in battle spaces.
However, the Su-57 jets, which will carry the missiles, are not scheduled to go into mass production in the near future.
Mr Borisov said: “It does not make sense to speed up work on mass producing the fifth-generation aircraft.”
He added: “It is our trump card, which we can always play when the aircrafts of previous generations will start to lag behind in capabilities when compared to similar aircraft from the world’s leading countries.”
Russia will instead largely use their advanced fourth generation fighter jets, including the MiG-29SMT Fulcrum and the Su-35S Flanker-E, until they lag behind international standards.
The country nevertheless placed its first order of 12 Su-57 fighter jets in June 2018, close to a decade after the programme was established.
The first pair of fighter jets are likely to arrive in 2019, with the remaining being delivered up to 2024.
