Bulgaria’s Defence Minister Dimitar Stoyanov said two U.S. Air Force KC-135 tanker aircraft temporarily based at Bezmer Air Base left the country on Friday, 21 August. Reuters and Anadolu Agency reported the statement separately on 22 August. Their departure does not mean the full parliamentary authorization for a larger number of aircraft and a longer period was used; the announcement confirms only the movement of the two aircraft that were present.
The temporary deployment framework
Bulgaria’s National Assembly voted on 22 July to authorize the temporary presence of up to eight KC-135 military aircraft and as many as 250 personnel. According to parliament’s official notice, the decision was made under defence cooperation arrangements between Bulgaria and the United States and covered the period from 24 July to 1 October. The record defines the maximum authorized scale, not the number physically present on every date.
The latest information from Bulgarian officials says the two aircraft located at Bezmer departed before the authorized period ended. Stoyanov said the movement took place in coordination with the U.S. government. The public statement did not provide details about the aircraft’s next destination or whether another deployment could occur under the same authorization. Only the stated departure date and aircraft count can therefore be treated as confirmed.
What KC-135 aircraft do
The KC-135 is a four-engine tanker platform designed to transfer fuel to other aircraft in flight. Bulgaria’s parliamentary announcement in July defined the legal and logistical framework for the temporary presence. The new statement about the aircraft leaving Bezmer did not disclose the details of a particular operation, flight route or next destination.
The report should remain limited to the confirmed movement and the earlier authorization. The departure does not by itself establish a permanent change in Bulgaria’s defence policy. The July parliamentary decision sets the authorized time window, while the minister’s statement records that the two aircraft then present had left. Those documents answer different questions and should not be treated as interchangeable.
Background to the debate
The temporary deployment prompted political debate in Bulgaria and an objection from Iran in July. Sofia said the decision relied on existing agreements and that security considerations had been reviewed. The official National Assembly record lists the maximum number of aircraft and personnel permitted. Associated Press also reported the July parliamentary decision and its scope independently.
Reuters’ 22 August report attributes the departure directly to the defence minister. Anadolu Agency also reported the statement, saying it was delivered to journalists during an event marking the anniversary of the Battle of Shipka. The two organizations are consistent on the central points: two aircraft left and the movement occurred on 21 August. The parliamentary record remains the primary source for the earlier legal framework.
What to watch next
Unless Bulgaria’s Defence Ministry or parliament issues a new notice, it would be premature to claim that the wider framework has ended or that more aircraft will arrive. Relevant points are the authorization through 1 October, the actual military presence at Bezmer and further statements from Bulgarian officials. Any new movement should be confirmed through official notice or multiple reliable sources.
The verified position is narrow but clear: according to Minister Stoyanov, the two KC-135 aircraft at Bezmer departed Bulgaria on 21 August. Broader strategic conclusions should not be presented as established developments without additional official records. The continuing legal authorization and the departure of these two aircraft can both be true at the same time.
