The Selectable Output Weapon (SO) is intended to provide a single, low-cost payload with multiple levels of explosive output for GBU-12 PAVEWAY and GBU-38 JDAM smart bombs.
Existing aircraft-to-weapons interfaces will communicate the desired explosive output level during weapon release. The weapon system will arm normally and, upon target detection or impact, activate the appropriate initiator(s) to deliver the desired output mode.
The SO bomb body will feature the same mass properties and aerodynamic shape as the existing MK82 / BLU-111 / BLU-126, making the payload compatible with existing release envelopes. In addition, the SO will be compatible with exiting logistics infrastructure, such as pallets and ordnance-handling equipment. Minimal changes to existing training tactics and procedure will be required. Although SO is a Navy program, the technology developed will be consistent with Air Force needs as well.
By controlling the blast and fragment footprint to match the combat scenario, the SO bomb will provide the warfighter with an effective means to quickly combat a broad spectrum of targets located in close proximity to allied forces, noncombatants and culturally significant sites without compromising the probability of kill. Because a single SO bomb is capable of multiple output levels, it will also provide a reduced logistic footprint.
The Office of Naval Research will initially pursue multiple technologies depending on their ability to meet program lethality and collateral damage objectives. Technology down select and maturation will depend on the cost-benefit tradeoffs that are identified as the program progresses. Static ground tests are planned for fiscal year 2015 with the intent to transition SO to an acquisition program of record in fiscal year 2016.
