Overview
- Flight-tracking services showed a U.S. Air Force C-17A Globemaster III operating as callsign RCH4555 with tail 07-7181 flew from Riga and landed at Moscow’s Vnukovo Airport on Tuesday, August 25, 2026.
- Tracking data recorded the Riga departure at about 08:50 Moscow time and the Vnukovo touchdown at about 10:04, and Flightradar24 later confirmed the full approach after initial position-data questions.
- Kremlin spokesman Dmitry Peskov said Russian officials had no information about the aircraft’s arrival and U.S. authorities have not publicly disclosed the mission, passengers, or cargo.
- Observers note the C-17’s configuration and recent stops at U.S. bases that handle senior-official travel make several mission types plausible, but open-source tracking and social-media footage do not establish who or what was aboard.
- Because U.S.-registered flights into Russia have been rare since 2022, this unexplained landing will be watched for official statements, the aircraft’s onward movement, and any confirmation that it relates to back-channel diplomacy or prisoner transfers.
