 * and F-13s. Pictures were taken of fireball development, nuclear cloud formation, the target area, and radar scopes inside the aircraft. Projects 11 through 14 consisted of technical photography from U.S. Navy aircraft. A variety of cameras were installed in PBMs, TBMs, F6Fs, and F6F drones to photograph wave motion, target array, target damage, and detonation effects on ships in real time. Project 15 used 20 cameras placed on target ships and nearby islands for shot ABLE and 24 cameras on target ships and nearby islands for shot BAKER to observe ship reaction to the detonation. Project 16 consisted of mounting high-speed cameras in a C-54 to measure the ABLE fireball growth. Project 17 consisted of mounting 50 icaroscopes on nine observer ships to observe bomb flash intensities (Reference C.9.190, p. 207). Project 18 mounted two drum spectrographs in a camera tower on Eneu to record the light's spectrum as a measure of time. Projects 15 through 18 were conducted by the Technical Photography Group of the Instrumentation Division. Project 19 used a high-speed camera on Bikini to photograph ABLE fireball development. This project was accomplished by the BuOrd Group of the Instrumentation Division.


 * Staffing: Personnel in the Technical Photography Group consisted of officers and enlisted men from the U.S. Navy and civilians. Of the civilians assigned, at least one was from Los Alamos Laboratory. The Navy Photographic Unit was aboard USS Saidor (CVE-117). In addition to the Technical Photo Group, the Army Air Task Group, TG 1.5, had one task unit devoted completely to photography. Army Air Photo Unit, TU 1.5.2, with several photographic aircraft, provided substantial support to this program.


 * For ABLE there was little chance for exposure on any of the projects except for Projects 6, 13, and 15, where cameras had to be recovered from B-17 and F6F drones and target ships. The drones were contaminated; however, none of the target ships with cameras were contaminated on shot ABLE. For BAKER, recovery of several projects created an exposure potential. Projects 2 through 7 required recovery of film from contaminated islands around the lagoon after BAKER. Projects 8 and 13 required recovery of film from contaminated B-17 and F6F drones. Project 15 required recovery of film from contaminated target ships after BAKER. Projects 18 and 19 required recovery of film from Eneu and Bikini, the beaches of which were contaminated after BAKER.
