Recon/Optical, Inc. (ROI) has developed the CA-260 Advanced Development E-O Framing Camera specifically to provide near-photographic quality images while enhancing the survivability of the tactical reconnaissance platforms at low to medium altitudes. The CA-260, mounted in a T-33 jet trainer, completed three successful engineering flight tests over the Edwards AFB test range on July 17 - 31, 1993. The flight tests were part of ROI's research and development program to develop E-O framing camera technology. These tests marked a major milestone in the program and proved that an E-O framing camera can successfully perform tactical reconnaissance missions. This paper presents the details of the engineering flight tests performed at Mojave, Calif. By way of introduction, the concept of E-O framing tactical reconnaissance and its advantages in terms of aircraft survivability are reviewed. The purpose, equipment configuration, mission specifics and flight summaries are discussed. Examples of flight test imagery are presented with some analysis of the CA-260's performance.
