US Lockheed Martin’s F-35 vs Russia’s Su-57, Key Features

As India aims to modernize its air combat capabilities, the choice between two fifth-generation fighter jets, the US Lockheed Martin’s F-35 vs Russia’s Su-57 has become a strategic decision with global implications. With both aircraft making headlines at Aero India 2025, India’s next move could reshape its military weapon inventory for decades.

Why India Needs a Fifth-Gen Fighter

India’s weapon inventory currently includes around 600 fighter jets, but none belong to the fifth-generation category. With increasing regional threats from China’s rapidly growing stealth fleet and Pakistan’s reported interest in acquiring similar technologies, India faces pressure to have a fifth-generation fighter. While domestic efforts like the Advanced Medium Combat Aircraft (AMCA) are underway, operational readiness is not expected before 2036. This opens the door for immediate imports, where the F-35 and Su-57 are top options.

F-35 Lightning II

The US Lockheed Martin’s F-35, is widely regarded as the world’s most advanced multirole fighter. It is available in three variants:

• F-35A for the Air Force
• F-35B with short take-off and vertical landing (STOVL) capabilities for the Marine Corps
• F-35C designed for aircraft carriers in the Navy

Key Features:

• Top Speed: Mach 1.6
• Combat Range: ~1,500 km
• Payload: 8,160 kg
• Fuel Capacity: 18,498 lbs
• Operational Altitude: Over 50,000 feet
• Sensors: Electro-Optical Targeting System (EOTS), Distributed Aperture System (DAS)
• Helmet-Mounted Display System (HMDS): Provides real-time targeting data and situational awareness
  

With more than 1,000 operational units worldwide and development support from nine partner nations, the F-35 is a battle-tested and interoperable platform in NATO operations.

Sukhoi Su-57

The Su-57, developed by Russia’s Sukhoi Design Bureau, is a twin-engine multirole stealth fighter designed for both air superiority and ground strike roles. Russia has pitched its export version, Su-57E, as a cost-effective alternative for partners like India.

Key Features:

• Top Speed: Mach 2
• Combat Range: ~1,900 km
• Payload: 7,400 kg
• Max Operating Altitude: ~54,100 feet
• Engine: Saturn AL-41F1
• Stealth Enhancements: Serrated exhaust nozzle and internal weapon bays
• AI Integration: Onboard “electronic second pilot” system
• Radar Spread: Distributed radar array across the airframe
  

Although only around 40 Su-57s have been produced as of 2025, Russia claims the aircraft matches or exceeds the F-35 in certain performance metrics, especially agility and range.

US Lockheed Martin’s F-35 vs Russia’s Su-57

The Lockheed Martin F-35 and the Sukhoi Su-57 represent two of the most advanced fifth-generation fighter aircraft developed by the United States and Russia, respectively. Designed for air superiority, stealth, and multi-role capabilities, both jets showcase cutting-edge technologies in modern aerial warfare. This comparison offers a detailed analysis of their design philosophies, capabilities, and strategic roles in shaping the future of air combat.

Strategic Considerations for India

India’s defense ties with both Russia and the US make the decision complex. Russia has been a longstanding defense partner, known for easier technology transfer and fewer restrictions. The US, while offering advanced systems, often includes stringent end-use monitoring clauses.

• Technology Transfer: Russia is more open to sharing tech; the US is more restrictive.
• Sanctions Risk: Buying from Russia risks CAATSA-related US sanctions; buying from the US risks geopolitical dependencies.
• Parts and Servicing: Russian jets can be supported locally with fewer dependencies.
• Geopolitical Alignment: A deal with the US could strengthen Indo-Pacific ties, especially in countering China.

Global Landscape

• F-35: Operated by over 14 nations, including the US, UK, Italy, Australia, and Japan.
• Su-57: Operational only in Russia, with no confirmed international buyers yet.
  

China, meanwhile, is rapidly closing the gap with over 200 J-20 stealth fighters and a growing fleet of J-35s, posing a real threat to India’s air dominance.
