Advanced Shotgun Projectile

Navy surface launched (2T) Non-Nuclear Expendable Ordnance (NNEO) are major and medium caliber gun ammunition, small arms ammunition, other ship gun ammunition, pyrotechnics, and demolition items. There are no other RDT&E budget items supporting the 2T NNEO program. This project currently supports the Guidance Integrated Fuze (GIF) demonstration and incremental development program, Multi-Function Fuze (MFF) and Advanced Shotgun Projectile. These items will be used with 5" caliber gun ammunition.

GIF is a "smart fuze", conforming to DoD and NATO interface requirements, that can be retrofitted on all 105mm, 5" and 155mm projectiles. While retaining all necessary conventional fuzing functions, GIF will provide GPS accuracy to the entire inventory of conventional projectiles. Multi-Function Fuze program is nearing completion, and provides performance, safety and logisitcs enhancements to the existing inventory of Navy Conventional Fuzes.

The Advanced Shotgun Projectile will provide effectiveness beyond the existing 5 inch Force Protection Rounds (HE-ET and KE-ET). The Advanced Shotgun Projectile will provide mission kill capability against the entire Fast Attack Craft/Fast Incoming Attack Craft threat. The Advanced Shotgun Projectile will utilize a fragmenting steel case with a high density pre-fragmented payload to minimize parasitic mass and provide guaranteed lethal fragments on target. The Advanced Shotgun Projectile will employ a forward-ejecting load to increase lethality against the small boat threat within the layered defense scenario.

The Advanced Shotgun Projectile effort for FY2007 consisted of determining a "Best Value" approach to providing a projectile with effectiveness beyond the existing 5 inch Force Protection Rounds (HE-ET and KE-ET) with application to all 5" Guided Weapon System (GWS) mission requirements. An Analysis of Alternatives type study will be conducted to determine the feasibility of pursuing an Advanced Shotgun Projectile with mission kill capability against the entire range of 5" GWS target threats. Initial concepts will focus upon utilizing a fragmenting steel case with a high density pre-fragmented payload to minimize parasitic mass and provide guaranteed lethal fragments on target.
