1760 INTERNAL WEAPONS BAY UPGRADE (IWBU)

Abstract

MIL-STD 1760 Internal Weapons Bay Upgrade (IWBU) requires the integration of the 1760 weapons capability into the bomb bay on seventy-six (76) B-52H aircraft utilizing Common Strategic Rotary Launcher (CSRLs) converted into Conventional Rotary Launchers (CRLs). The 1760 IWBU program is segmented into two Increments; Increment 1 consists of two sub-increments 1.1 and 1.2. Increment 1.1 consists of internal carriage of eight Joint Direct Attack Munitions (JDAM) and variants, to include Laser JDAM (L-JDAM), on a rotary launcher. Additionally, L-JDAM will be integrated on external hard points during this effort. The CRL Hardware modification consists of Group A equipment racks and electrical wiring and Group B consists of one Integrated Weapons Interface Unit (IWIU) per CRL. This Line Replaceable Unit (LRU) was previously developed under the Advanced Weapons Integration (AWI) program and work was previously accomplished for a 2005 demonstration or developed using 2006 and 2007 Congressional Add funding. CSRLs will lose their nuclear capability when modified into a CRL. No new Nuclear CSRLs will be required. The aircraft software modification consists of modifying existing aircraft, JDAM Stores Management Overlays (SMO), and ground based Joint Mission Planning System (JMPS). CRL Hardware modification: Consists of Group A equipment racks and electrical wiring, Group B consists of one Integrated Weapons Interface Unit (IWIU) per CRL, this Line Replaceable Unit (LRU) was previously developed under the Advanced Weapons Integration (AWI) program and work previous accomplished for a 2005 demonstration or developed using 2006 and 2007 Congressional Add funding. CRLs will lose their nuclear capability until integration of the MIL-STD 1760 System II nuclear munitions and development and integration of a nuclear hardened IWIU. No new Nuclear CSRLs will be required. Aircraft Software modification: Consists of modifying existing aircraft, JDAM Software and ground based Joint Mission Planning System (JMPS). Increment 1.2 provides capability for internal carriage of eight Joint Air to Surface Standoff Missiles-Extended Range (JASSM-ER) or eight Miniature Air Launched Decoys (MALD). Internal capabilities include authorized munition variants, for example, JDAM, GBU-31 (v)1, (v)3, GBU-38, JASSM, and MALD-Jammer (MALD-J). CRL Hardware modification: Consists of modifying the Increment 1.1 configuration by adding four Group B LRUs, (up to three power supplies and one junction box) and Group A associated interface wiring. Aircraft Hardware modification: Consists of Group A wiring and circuit breakers to supply additional power to the CRL. Aircraft Software modification: Includes modifying existing JASSM-ER, MALD software. Support Equipment: Thirty-eight (38) Multi-Use System Tester Armament Next Generation (MUSTANG) testers will be modified to support both increments. A future Increment (Increment 2) will provide carriage expansion of the CRL through a software and hardware modification and will increase the number of weapon stations from 8 to 16 and provide mixed load capability. This will occur after Increment 1 completes. B-52 Advanced Weapons Integration (AWI) initiatives previously managed under MN-4260 are now managed under two separate modifications for clarity in effort, funding and schedule. The initiatives are now described in MN-4260 Advanced Weapons Integration (AWI) and MN-6884 MIL-STD-1760 Budget Item Justification: FY14 continues Increment 1.1 development, continues SEEK EAGLE safe separation analysis, and conducts ground and flight testing of CRL prototype and JDAM SMO. Continue B-52 Joint Mission Planning System (JMPS) and Trainer/GMCP software. Finalize drawings for CRL, and test support equipment modification kits to support Milestone C activity. Begin development of technical orders in preparation for kit-proof. Modify three prototype CRLs. BA7- This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in the current or subsequent fiscal year.
