556 RS

In 1968 this unit became the 556th Reconnaissance Squadron.

All the drones were carried and started from specially modified GC-130As, MC-130AS and - finally - DC-130A and DC-130E control aircraft, each of them being equipped with systems for carriage, start, control and guidance of drones. The drones were always pre-programmed, but after release their progress was monitored and the drone controller could override the programme manually if necessary. The carrier aircraft had a console for two controller pilots equipped with all the usual flight-instruments, which read the data sent to them from the drone. All the data about the navigation, planned route, the actual flight pad and position of the drone and the carrier aircraft were feed into a single system, which showed them on one display. On their return the drones deployed a parachute and were snared by specially modified HH-3E recovery helicopters.

From 1969, first serious encounters with North Vietnamese (manned) interceptors followed. In 1969 alone, Vietnamese fighters - mostly MiG-21s - were scrambled no less than 540 times in order to intercept drones, claiming to have shot down ten Firebees. Actually, there were kills, but they were scored by Americans - and indirectly. In May 1970, an AQM-34L was on a mission over Hanoi

 area, acting as a manned reconnaissance aircraft. Finishing its photo-run, the drone turned toward the Tonkin Gulf, where it was to ditch after spending its remaining fuel. Almost everything was going according to plan - down to one detail: the drone was intercepted by an MiG-21. The fighter closed and tried to shot it down by two K-13/AA-2 Atoll air-to-air missiles. Both malfunctioned however, and the Vietnamese continued the pursuit, trying to down the drone by tackling its wing. By doing so, the SRVAF-pilot forgot to control his fuel reserves: after the drone fell harmlessly into the sea, he found out that he had not enough fuel to return to base. The Vietnamese ejected while flying back toward the coast. This was the first air-to-air kill scored by an unmanned aircraft in the history of air warfare.

In addition to the drone operations, the squadron received significant amounts of intelligence operating a RB-57F Canberra from Yokota AB, Japan detached from the MAC 9th Weather Reconnaissance Wing at McClellan AFB, California. The RB-57 provided very high altitude intelligence with regards to SA-2 locations for mission planning with the Firebees.

As part of the drawdown of United States forces from South Vietnam, the 556th moved to Yokota AB, Japan in 1971, although operations continued from South Vietnamese air bases until 30 Jun 1972 when the squadron was inactivated.
