YF-84F and YRF-84F prototypes in 1952. Note the early style wing root jet intakes, which were eventually only retained on the RF-84F, due to the need to fit cameras in the nose. The standard F-84F reverted to the original nose intake due to a loss of thrust from the wing root intakes.
RF-84F Thunderflash, the reconnaissance version of the F-84F. Note the unique articulation of the canopy, which is mounted on a pair of hydraulic rams and a lever arm, allowing it to automatically pivot up and backwards behind the cockpit.
