Guided Projectile
Abstract
Projects 3401: The Gun Launched Guided Projectile (GLGP) program leverages Hypervelocity Projectile (HVP) technology developed under each of the respective Strategic Capabilities Office (SCO) and Office of Naval Research (ONR) Future Naval Capabilities (FNC) programs to provide gun-based Anti-Ship Cruise Missile (ASCM) defense. The Gun Launched Guided Projectile program is cancelled in FY2022 due to cost and is concluded in FY2021. Gun-based ASCM defense capability increases both ship's weapon capacity against ASCM raids and battle persistence in successive ASCM raids. The performance improvement is achieved without relying on Vertical Launch System (VLS) cells for weapon deployment. This effectively deepens the ship's magazine for raid defense and supports larger allocation of VLS cells to offensive capability. In addition to improved capacity and battle persistence, gun-based ASCM defense solutions provide a cost effective response to an ASCM attack due to the unit cost of the projectile relative to missiles. The introduction of gun-based ASCM defense for large caliber guns is made possible by recent advancements in microelectronics, sensors, and energetic systems that enable precision guidance and tailored lethality. GLGP incorporates these HVP technologies into an aerodynamically streamlined sub-caliber airframe to achieve a highly maneuverable projectile. When launched from the MK 45 Gun Weapon System (GWS) at high velocities, GLGP's high maneuverability combined with high kinetic energy at the intercept yields effectiveness against ASCMs. Initial HVP technology demonstration focused on land-based system integration and implementation. Shipboard integration requires some modifications to the initial concept of operations to implement the technology effectively and affordably. This project matures critical enabling technologies needed to integrate HVP technology on Navy ships and executes the requisite acquisition, systems engineering, and test planning activities to initiate a development effort.
