Mortar Modification

Mortar Modification is a new start in FY 2024 and aims to provide modification support for mortar weapon systems, including the 60mm Lightweight M224A1, 81mm Lightweight M252A1, and 120mm M120A1/M121. The program's specific objectives include the replacement of aging or obsolete major system components and subcomponents, such as Basic Issue Items (BII) kits, Additional Authorized List (AAL) items, Modified Work Order (MWO) kits, Engineering Change Proposals (ECPs), and Technical Data Packages (TDPs). These modifications are intended to increase producibility, manufacturability, and procurement of required assets within the United States industrial base. Additionally, the program aims to support higher firing pressures, integrate new components for system accuracy and reliability, and address obsolescence and technical issues related to weapon system safety.

Furthermore, the Mortar Modification program seeks to address obsolescence, improve soldier safety, and enhance the maneuverability of mortar systems currently fielded to Infantry Brigade Combat Teams (IBCTs), Stryker Brigade Combat Teams (SBCTs), Armored Brigade Combat Teams (ABCTs), as well as the Special Forces Groups and Ranger Regiments. The specific goals include supporting tactical vehicle integration efforts to address Mortar Stowage Kit (MSK) upgrades and M1101/M1102 trailers obsolescence, producibility, and soldier safety requirements. These efforts are essential to meet US Army requirements for addressing obsolescence and improving soldier safety while enhancing the manufacturability of mortar systems. Additionally, this program is necessary for use by the active and reserve components of the Armed Forces for homeland defense missions, domestic emergency responses, and providing military support to civil authorities in accordance with Section 1815 of the FY 2008 National Defense Authorization Act (P.L 110-181).
