EDO has developed a MIL-STD-1760 multiple carriage bomb rack that effectively doubles the number of smart weapons that can be carried by tactical strike aircraft such as the F-16. This is accomplished with minimal impact to the aircraft’s Operational Flight Program and with no modification to aircraft hardware. Patented electronics are installed in existing inventory BRU-33 Vertical Ejector Racks (VER) to enable the carriage of not only "dumb" stores but a wide array of newly developed "smart" stores such as JSOW, JDAM and WCMD. At the heart of the system is an innovative Bus Buffer Assembly that permits the aircraft to communicate with the carried stores as if they were on the aircraft’s main data bus. A BRU-33 modified with such electronics and USAF standard BRU-46/A ejector units is designated BRU-57.

The BRU-57 has been fully flight qualified for use on F-16’s and is currently in full rate production. The BRU-57 is qualified to MIL-STD-7743, MIL-STD-810, and MIL-STD 461/462.
