RB 66 - B Destroyer The twin-engine high swept wing Douglas RB-66 Destroyer entered in service in the mid- 50s to equip the USAF photo-reconnaissance squadrons. Derived, as the Douglas B-66 bomber version, from the A-3 Skywarrior, it had adopted a lot of changes compared to the US Navy aircraft. Thanks to the two J71 turbojet engines, the Destroyer was able to reach a max speed of 940 Km/h and guarantee an operative range of 1,800 miles. The equipment for the reconnaissance were installed in the loading bombs bay. A lot of RB-66s had been used by the USAF Squadrons located in Great Britain, Germany and Japan during the escalation of the Cold Wars proving their effectiveness in the intelligence and recon duties.
