Russian Airforce SU-57 carrying 2x BVRAAM R-37M. Russia Offers R-37M
Russia has reportedly offered India its most lethal long-range air-to-air weapon—the hypersonic R-37M—for integration with the Indian Air Force’s frontline Su-30MKI fighter fleet, potentially redefining South Asia’s airpower balance.
If accepted, the offer would significantly improve the IAF’s beyond-visual-range (BVR) interception capability, putting high-value enemy assets at risk hundreds of kilometers outside Indian airspace.
The offer comes at a politically and militarily sensitive time, following Pakistan’s reported downing of six Indian Air Force jets in a recent skirmish with Chinese-supplied PL-15 air-to-air missiles fired from enormous distances.
According to open-source intelligence and unofficial defense reports, the PL-15 launches were most likely carried out by Pakistan Air Force J-10C fighters at ranges greater than 182 kilometers, far beyond the capabilities of India’s current BVR arsenal.
In that context, arming Su-30MKIs with the Russian R-37M, which has a strike range of 300–400 kilometers, could enable India to preemptively neutralize enemy fighters, AWACS, or aerial refueling assets before they are detected.
272-Unit Approved
As of June 2025, the Indian Air Force operates approximately 259 to 262 Su-30MKI aircraft, making up the majority of India’s air combat inventory.
These aircraft are part of a 272-unit approved acquisition plan that includes both direct deliveries from Russia and licensed production by Hindustan Aeronautics Limited (HAL) in India.
In December 2024, New Delhi signed a deal worth ₹13,500 crore (approximately US$1.5 billion) to procure 12 additional Su-30MKI airframes. These will be assembled domestically under HAL’s “Make in India” framework, with over 62.6% indigenous content.
The R-37M, also known as RVV-BD (Raketa Vozduh-Vozduh Bolshoy Dalnosti), stands out as one of the most advanced and dangerous long-range air-to-air missiles in service today.
Originally based on the older Soviet-era R-33, the R-37M has undergone extensive upgrades. As a result, it now integrates seamlessly with Russia’s latest interceptors and multirole fighters like the MiG-31BM, Su-35S, and even the stealthy Su-57.
Indian Air Force
More importantly, engineers designed the missile to target and destroy high-value airborne assets. These include AWACS aircraft, strategic bombers, aerial refueling tankers, and even fighter jets flying in support or at a safe distance.
The R-37M is 4.06 meters long, 0.38 meters in diameter, and weighs around 510 kilograms at launch, with a 60-kilogram fragmentation warhead capable of catastrophic kill effects with a single impact.
Its main advantage is its unrivaled range—up to 400 kilometers—making it the longest-ranged AAM currently fielded by any air force worldwide.
A two-stage solid-propellant rocket motor powers the missile, enabling it to exceed Mach 6 and reach hypersonic speed. This extreme velocity severely limits the adversary’s time to react.
The guidance system combines inertial navigation with mid-course updates via a data link. An active radar seeker takes over in the terminal phase, allowing the missile to accurately hit fast and maneuverable targets.
Vympel NPO
Russian missile manufacturer Vympel NPO developed the R-37M and placed it into full-scale service with the Russian Aerospace Forces.
They primarily mount it on MiG-31BM interceptors under a strategic anti-AWACS doctrine that aims to cripple NATO’s airborne surveillance and command systems.
Russian forces have reportedly used the R-37M in the ongoing conflict with Ukraine. NATO analysts and Western intelligence agencies continue to monitor its performance closely against Ukrainian aircraft and surveillance platforms.
Operational reports suggest the missile worked reliably, even in heavy electronic warfare conditions. This performance has sparked growing interest among major air forces, including India.
If India acquires the R-37M, it could greatly expand its air-to-air strike range. Indian jets could then hit enemy aircraft before they enter contested or protected zones. This advantage could significantly alter the air combat scenario along India’s western and northern borders.
R-37M and Su-30MKI: Strategic Edge in South Asia
Adding R-37M missiles to India’s Su-30MKI platforms could significantly impact any future aerial conflict with Pakistan or China.
>In a Pakistani theater scenario, Su-30MKIs armed with R-37Ms could threaten and destroy PAF airborne early warning assets like the Saab 2000 Erieye and ZDK-03 Karakoram Eagle from beyond their engagement range.
Such an attack would impede Pakistan’s ability to maintain situational awareness and command coordination in air combat zones, reducing fighter effectiveness and creating critical gaps in operational command and control.
R-37M-equipped Su-30s could target PAF IL-78 tankers, disrupting refueling of F-16s and JF-17s in battle. By cutting refueling chains, India’s fighters gain time and space advantages during prolonged operations against Pakistan’s frontline assets.
In mountainous regions like Tibet and Aksai Chin, Su-30MKIs can engage Chinese high-value targets from long standoff ranges. The KJ-500 AWACS and Y-20 tankers would face serious threats without ever seeing the Indian jets approach.
Chinese escort fighters like the J-10C or Su-35S would be vulnerable well outside their own missile engagement ranges. By knocking out their shield, India creates openings for deep-penetration strikes with Rafale, Tejas, and Mirage 2000 jets.
These strike corridors reduce early interception risk, improving mission success and preserving precious airframes in contested zones. To succeed, India must upgrade Su-30MKI radars and secure datalinks for real-time R-37M guidance during long-distance shots.
Without these upgrades, the missile’s range won’t be used effectively in fast-changing air combat scenarios. However, if India cracks the integration challenge, the Su-30MKI becomes more than a regional fighter—it turns strategic.
It could then engage enemy tankers, AWACS, and bombers far beyond the range of China’s and Pakistan’s interceptors. Such reach could reshape regional air power balance, giving India a first-strike or denial edge in any crisis.
Conclusion
From a geopolitical view, the R-37M changes Asia’s balance of airpower in a big way. As a result, China and Pakistan may need to rethink their airborne command and control strategies.
They’ll also likely reposition AWACS aircraft to avoid straying into the missile’s dangerous engagement envelope. Moreover, both countries may adjust their refueling plans to reduce exposure during combat operations.
This shift could push them to develop new long-range missiles to match India’s expanding reach. In the bigger picture, India’s use of the R-37M marks a major turning point in regional airpower.
It shows that in today’s skies, range and precision matter more than just numbers or size. Ultimately, whoever fires first and hits farthest now holds the real edge in modern aerial warfare.
