"The B-52H Integrated Weapon Interface Unit (IWIU) program is a newly developed Line-Replaceable Unit (LRU) which will replace the current 1980s-developed LRUs which are becoming unsupportable. The LRUs currently installed in the Stub Pylon / Heavy Stores Adapter Beam (SP/HSAB) provide the command and control link between the B-52H Offensive Avionics System and all “smart” MIL-STD 1760 current and future weapons carried on the B-52H."
