CIA chief was aboard mystery US C-17 flight to Moscow

We now know why a US Air Force C-17 made an unusual flight from Riga to Moscow: CIA Director John Ratcliffe was aboard the aircraft for meetings in the Russian capital.

The reason behind an unusual US Air Force C-17 Globemaster III flight into Moscow has now emerged, with CBS News reporting that CIA Director John Ratcliffe travelled aboard the aircraft for meetings in the Russian capital, the UK Defence Journal understands.

The development answers the central question raised when the aircraft appeared on civilian flight-tracking services earlier on 25 August. What initially looked like a highly unusual American military transport movement into Russia was, according to CBS News senior White House reporter Jennifer Jacobs, carrying the CIA Director on a visit to Moscow. Jacobs reported, citing sources, that Ratcliffe travelled to Russia aboard a C-17 for meetings in the city and said it appeared to be his first known trip to the country since becoming CIA Director, although he has maintained contact with Russian intelligence counterparts.

The aircraft was identified through open-source flight data as US Air Force C-17A Globemaster III serial 07-7191, using the callsign REACH 4555. It had first been tracked leaving the Washington area for Riga on 23 August, before departing the Latvian capital two days later and heading east towards Moscow, a routing that immediately drew attention because direct movements by identifiable US military aircraft into Russia have become extremely uncommon amid the deterioration in relations between Washington and Moscow.

UK Defence Journal Senior Editor Jon, known as DefenceGeek on X, followed the movement as it developed, first noting the aircraft’s arrival in Riga and then its subsequent flight into Russia. Tracking data showed REACH 4555 approaching Moscow before video and photographs from the city showed a C-17 descending towards the Russian capital, confirming that the aircraft had completed the unusual journey.

At that stage, however, the aircraft itself offered little indication of what the mission involved. The C-17 is the US Air Force’s principal heavy strategic transport aircraft and is routinely used to move personnel, vehicles and outsized cargo over intercontinental distances, while REACH callsigns are commonly associated with US Air Mobility Command missions, meaning the route could be followed in public without revealing who was aboard or why the aircraft had been sent to Moscow.

The CBS reporting changes that picture considerably, placing the flight in the context of a senior US intelligence visit rather than an unexplained logistics movement. Ratcliffe’s reported presence also helps explain why a conspicuous military aircraft was being used on a route that would otherwise have appeared highly unusual, although the precise purpose of his meetings, the Russian officials he met and the subjects discussed have not been made public.

Separate activity around the flight had already suggested that the movement involved more than a routine cargo mission. Imagery circulating after the C-17 arrived appeared to show US government vehicles travelling in convoy through Moscow, with open-source observers pointing to registration plates that appeared consistent with Latvia-issued diplomatic plates. The timing now makes a connection with Ratcliffe’s visit more plausible, although the available imagery does not establish whether those vehicles carried the CIA Director, formed part of his security detail or had any direct connection with the delegation.

There was also additional US government aviation activity at Riga before REACH 4555 continued to Moscow. A Boeing C-40, serial 02-0042 and using the callsign REACH 790, was tracked arriving at Riga International Airport from Joint Base Andrews on 23 August, with open-source imagery suggesting that it was parked close to the C-17. That movement can now be viewed alongside Ratcliffe’s reported journey, but there is still no confirmation that the C-40 continued to Russia or that it played a direct role in the CIA Director’s visit.

Jacobs’ reporting that Ratcliffe has maintained contact with Russian intelligence counterparts is also significant because it indicates that direct intelligence channels between Washington and Moscow have continued despite the wider breakdown in political and military relations. What those contacts have covered remains unknown, and there is no public information establishing whether the Moscow meetings concerned Ukraine, detainees, strategic stability, intelligence liaison or another issue.

The known sequence is now considerably clearer than it was when REACH 4555 first appeared over Russia: the aircraft travelled from the United States to Riga, later flew onward to Moscow, and was subsequently identified by CBS News sources as carrying the CIA Director for meetings in the Russian capital. The reason for the flight is therefore no longer the mystery it was when the movement was first detected, even if the substance of Ratcliffe’s discussions remains undisclosed.

The US Air Force declined to comment when approached about the flight, while no detailed public account of Ratcliffe’s meetings has yet been issued by the CIA or Russian authorities. What remains unanswered is not why an American C-17 was in Moscow, but what brought the CIA Director there and what was discussed once he arrived.
