Seven Douglas B-26 Invader medium bombers were illegally sold to Portugal in 1965, before U.S. authorities discovered the scheme and arrested the pilot responsible for the transfers. Two of the covertly acquired aircraft saw service in Guinea beginning in March 1971, when aircraft 7104 and 7106 deployed to Bissalanca for an operational evaluation. During three months of combat appraisal the B-26s logged approximately 200 hours over Guinea, providing valuable experience for subsequent operations in Angola, where the aircraft were ultimately based. FAP Invaders received an aluminium paint scheme with white upper surfaces and a dark blue separation fillet along the fuselage. The section of nose fairing facing the cockpit was painted anti-reflective black. (Artwork by Paulo Alegria)
