The RF-5A (N-156C) is the reconnaissance version of the F-5A. It was ordered in October of 1967, but did not make its first flight until May of 1968. It retained some combat capability with the additional provision of four KS-92 cameras mounted in the nose. The KS-92 camera was provided with an individual light sensor and individual light sensor and automatic exposure and had a 100-foot magazine. The cameras gave forward oblique, trimetrogon and split vertical coverage. All four cameras could be removed, reloaded and replaced within five minutes. The use of different lenses gave six basic camera configurations.
The RF-5A could be distinguished from its single- seat fighter cousin by the rather angular nose cutouts for the camera ports. The cameras were accessed via the upper surface of the nose which hinged forward. The aircraft was otherwise quite similar to the F-5A. Both cannon were retained, even when the cameras were fitted. In theory, the nose of the RF-5A could be replaced by the standard F-5A nose, but in the field this operation took too long to be practical.
The first of 89 RF-5As was delivered in the late 1960s. The first customer was the Imperial Iranian Air Force, followed by the air forces of Greece, Morocco, Norway, South Korea, South Vietnam, Thailand, and Turkey.
