M-Code
Abstract
The M-Code (ACAT IVT) Increment I program upgrades the Tactical Tomahawk to the next generation Global Positioning System (GPS) satellite constellation required to maintain GPS-provided position, navigation, and timing (PNT) for the missiles and is planned for Milestone C production decision in FY 2025 and Initial Operating Capability (IOC) in FY 2027. M-Code required a replan due to delayed delivery of the Application Specific Integrated Circuit (ASIC) chip development by the USAF Small Diameter Bomb (SDB) II Program Office. This action resulted in a schedule breach to the TACTOM M-Code APB Milestone C original threshold of August 2023. The M-Code mandate and Public Law restricts the purchase of only M-Code-capable GPS User Equipment (MGUE) after FY 2017 unless a waiver is granted by the Secretary of Defense.
