The Sukhoi Su-57D, a twin-seat variant of Russia's fifth-generation stealth fighter, successfully completed its maiden flight, a significant milestone for the aircraft's development. The flight was conducted by chief test pilot Sergei Bogdan and marks a step forward in the multirole capabilities of the Su-57 program. The Su-57D retains the overall design of the original Su-57 but includes an elongated cockpit to accommodate a second crew member, enhancing its operational versatility for long-range strike missions and complex battlefield management. The modifications made to the cockpit and internal systems are designed to maintain the aircraft's stealth characteristics and overall performance. Russian officials, including First Deputy Prime Minister Denis Manturov, expressed confidence in the aircraft's unique combat capabilities and its potential as a trainer and combat control platform. The Su-57D's development is also seen as part of Russia's renewed efforts to market the Su-57 to foreign operators, particularly India, which had previously shown interest in a twin-seat fighter variant during its partnership in the Fifth Generation Fighter Aircraft program. The aircraft's recent appearance at Aero India further highlights its export potential.
