Pyrotechnic Multiple Carriage - MIL-STD-1760
BRU-55A/A – smart twin store carrier
The Harris BRU-55/A smart rack doubles the number of MIL-STD-1760 smart weapons that can be carried on tactical strike aircraft such as the F/A-18 C-F. This is accomplished with no modification to aircraft wiring. The electronic control assembly installed within the nose and tail fairings of the F/A-18’s Canted Vertical Ejector Rack (CVER) provides a class II 1760 interface to the aircraft and one 1760 class II interface to each of the two weapons carried on the CVER.
Digital communications to the weapons on the BRU-55/A are passively coupled to the aircraft MIL-STD-1553 data bus thereby minimizing updates to the aircraft Operational Flight Program (OFP).
BRU-57 – smart twin store carrier
The MIL-STD-1760 multiple carriage bomb rack 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. Harris patented electronics are installed in the BRU-57 fairings to enable the carriage to carry a wide array of precision-guided munitions such as JSOW, JDAM and WCMD.
At the heart of the system is an innovative and patented bus buffer assembly that permits the aircraft to communicate with the carried weapons as if they are electrically connected directly to the aircraft’s main data bus. The BRU-57 uses two Harris USAF BRU-46/A ejector racks.
The BRU-57 has been fully flight qualified for use on F-16s and is currently fielded. It is qualified to MIL-STD-7743, MIL-STD-810, and MIL-STD 461/462.
