1760 INTERNAL WEAPONS BAY UPGRADE (IWBU)

Abstract

Beginning in FY13 Project Number 675048, 1760 Internal Weapons Bay Upgrade program transferred from Project Number 675039, B-52 Modernization. MIL-STD 1760 Internal Weapons Bay Upgrade (IWBU) modifies aircraft software and the Common Strategic Rotary Launcher (CSRL) to carry MIL-STD-1760 based munitions in the B-52 internal weapons bay. This effort leverages the Integrated Weapons Interface Unit (IWIU) hardware developed under the Advanced Weapons Integration (AWI) program and previous work accomplished for a 2005 demonstration or developed using 2006 and 2007 Congressional Add funding. Production requirements include modification of 76 B-52 aircraft (Group A) and 44 CSRLs (Group B). No new CSRLs will be procured with this effort. This program will install MIL-STD 1760 interface cables and connectors on all B-52 aircraft, and will remove current munitions interface components, cables, connectors and mounting brackets from 44 CSRLs and replace removed items with MIL-STD 1760 capable components. Modified CSRLs will become "Conventional Rotary Launchers (CRLs)" and will lose their nuclear capability until integration of the MIL-STD 1760 Series II nuclear munitions and development and integration of a nuclear hardened IWIU. The sole line Replaceable Unit (LRU) for this modification is the IWIU, which is the same unit used for control of MIL-STD 1760-based munitions carried externally on the pylon. Phase I of the program, which supports eight-carriage capability on the CRL, will procure and install 44 IWIU pairs (one pair per CRL). Phase 2 will provide carriage expansion on the CRL through a software modification, and will increase the number of weapon stations from 8 to 16. Phase II will occur after Phase I procurement and installation is complete, using RDT&E funding. B-52 Advanced Weapons Integration (AWI) initiatives previously managed under MN-4260 are now managed under three separate modifications for clarity in effort, funding and schedule. The initiatives are now described in MN-4260 Advanced Weapons Integration, MN-4693 Avionics Midlife Improvements, and MN-6884 MIL-STD-1760.
