The BSU-11AB Conical Bomb Fin was designed as a replacement for the MAU-93B Fin currently used on the MK 82 low drag general purpose bomb. The purpose of this evaluation was to determine the operational suitability, effectiveness, and limitations of the BSU-11AB, with emphasis on comparing it to the MAU-93B. Testing, consisting of manual deliveries of inert MK 82 bombs with BSU-11AB and MAU-93B fins, was made at dive angles of 15, 30, and 45 deg on the Nellis ranges, and a dynamic stability study was performed. Additionally, all aspects of ground handling and buildup were evaluated, including a timed build-up test and an F-111 aircraft fit check. It was concluded that the quickattach bolt and clamp mechanism of the BSU-11AB was unsatisfactory for field use. Statistically, there were no significant differences in dispersion and accuracy of the BSU-11AB and the MAU-93B however, variation in ballistics may become significant in high-time-of-flight deliveries. Stability characteristics were the same and a 44 percent build-up time was saved with the BSU-11AB.
