Overview
- The prototype, which flew Tuesday, was piloted by Sukhoi chief test pilot Sergei Bogdan as TV Zvezda and Rostec released confirming video and photos.
- Researchers identified the jet as bort 055 Blue, a rebuilt T-50-5R airframe, indicating a conversion of an older prototype rather than a clean new-build.
- Officials describe a dual role that adds an airborne battle-management station to trainer duties to coordinate crewed fighters and S-70 Okhotnik drones.
- The program begins a multi-year test campaign with no disclosed production schedule or procurement numbers, so operational use and exports remain uncertain.
- Russia is pitching the variant to India with promises of technology transfer and Indian-weapon integration, though New Delhi has not publicly responded.
