RB-66B Destroyer

The Douglas Destroyer was initially manufactured in two separate versions--a reconnaissance version designated RB-66B (Douglas Model 1329) and a bomber version designated B-66B (Douglas Model 1327A). They were basically similar in overall configuration, differing primarily in the equipment carried. The RB-66B carried flash bombs in its bomb bay for night photography missions and was equipped with a battery of reconnaissance cameras. The RB-66B could be fitted with a removable inflight refuelling probe attached to the right side of the forward fuselage.

The first RB-66B flew in March of 1955, and deliveries began on February 1, 1956. 145 RB-66Bs were built, which made this version numerically the most important of the Destroyer variants. The RB-66B was basically similar to the RB-66A pre-production aircraft, differing in being powered by Allison J71-A-11 turbojets. Higher-thrust J71-A-13 turbojets were fitted at the factory to the last 17 RB-66Bs built, and earlier machines were retrofitted with these engines.

The first RB-66Bs were issued to the 9th Tactical Reconnaissance Squadron of the 363rd Tactical Reconnaissance Wing, based at Shaw AFB in South Carolina in January of 1956. They replaced the obsolescent RB-26 Invader. Two more squandrons within the 363rd TRW, the 41st and the 43rd, were equipped with RB-66Bs by the end of the year. The RB-66B very soon became the primary night photographic reconnaissance weapon system of the Tactical Air Command.

The 12th TRS baseed at Itami, Japan, received its first RB-66Bs by the end of 1956. Two RB-66B squadrons were activated within the USAF in Europe.

In the mid-1960s, 52 RB-66Bs were modified as EB-66E electronic countermeasures aircraft. All of the reconnaissance equipment was removed and replaced by electronic jamming equipment. The tail turret was removed, and automatic jamming equipment was fitted in its place. Numerous antennae protruded from the aircraft, and chaff dispensing pods were carried. They were used during the Vietnam War as electronic warfare aircraft, joining strike aircraft during their missions over North Vietnam to jam enemy radar installations.
