A recently released photograph by Russia’s United Aircraft Corporation (UAC) of its under-development Sukhoi Su-75 Checkmate fifth-generation stealth fighter has generated excitement across global defence circles. First showcased at MAKS 2021 in the presence of President Vladimir Putin, the aircraft is yet to make its maiden flight. However, the new image, which also shows the tail of the Su-57 Felon – Russia’s only operational stealth fighter – suggests that field testing of the Su-75 may soon begin. The photo, posted by UAC on its Telegram channel on October 3, 2025, has intensified speculation about the aircraft’s readiness. A technician is seen standing near the Su-75 holding an orange wheel chock, while the aircraft’s rear wheels are already secured. Both the Su-75 and Su-57 feature a matching chequered paint scheme, hinting at coordinated testing activities.
