553d Reconnaissance Squadron

The 553d Reconnaissance Squadron is an inactive United States Air Force unit. It was last assigned to the 388th Tactical Fighter Wing and stationed at Korat Royal Thai Air Force Base. It was first active during World War II as the 10th Photographic Reconnaissance Squadron.

History
Constituted in 1942 as the 10th Photographic Squadron, the squadron conducted replacement training in Oklahoma for aircrew and photographic technicians.

Established as the 553d Reconnaissance Squadron in 1967 at Otis AFB, Massachusetts. Moved to Thailand as an electronic warfare squadron to detect vehicles along the Ho Chi Minh Trail in Indochina. If enemy vehicles could be detected then stopped, then a major quantity of enemy supplies into South Vietnam would be halted.

The "electronic fence" concept envisioned using Navy sonobuoys delivered along the Ho Chi Minh Trail by air, with special receivers in the 553d Reconnaissance Wing EC-121 aircraft to pick up the signals. The EC-121 would, when in range, automatically relay the signals picked up to the Infiltration Center at Nakhon Phanom RTAFB. Several target areas along the Ho Chi Minh Trail were outside of the range of the relay equipment; during out of range flights the signals were processed manually by the crew on board the EC-121R, then radioed via High Frequency Single Side Band radio directly to Seventh Air Force Headquarters in Saigon, South Vietnam.

The 553rd Reconnaissance Squadron was known as The "Batcats".
