Project 2038: The 25mm MK 38 MOD 2 and MOD 3 Machine Gun Systems (MGS) provide Anti-Surface Warfare (ASUW) and Anti-terrorism and Force Protection (AT/FP) capability as a simple, stabilized, low-cost solution to outfit near-term deployers to counter small boat threats. Over 360 U.S. Navy-owned systems are installed on U.S. Navy AS, CG, CVN, DDG, LCC, LHA, LHD, LSD, OSV, PC class ships, MK VI Patrol Boats and U.S. Coast Guard Fast Response Cutters. Established in order to respond to Joint Urgent Operational Need Statement (JUONS) CC-0558 for Counter Unmanned Aerial Systems (C-UAS), the MK 38 MOD 3 MGS's electro-optical/infra-red sensor, hardware, and software are being upgraded to counter emerging unmanned aerial threats. Initial C-UAS capability was fielded in Q1FY 2020. Incremental improvements are being made to this C-UAS capability, for cybersecurity and to address operability issues. The 30mm MK 38 MOD 4 Gun Weapon System, will introduce greater accuracy, lethality, and effective range for C-UAS and Counter Unmanned Surface Vehicle (C-USV) capability with integration to highly accurate fire control system, 30mm gun, targeting sensor and AEGIS combat system. The MOD 4 will be fielded on all DDG 51 Flight IIA and Flight III AEGIS Destroyers. Project 2038 provides qualification and logistics development of the 30mm MK 38 MOD 4. This will include Function Integration Testing, Functional Acceptance Testing, AEGIS Light-off, Structural Test Firing, and an at-sea Quick Reaction Assessment (on board DDG 89). Upgrading fielded 25mm MK 38 MGS to MOD 3 with C-UAS and concurrently developing and fielding the MK 38 MOD 4 Gun Weapon System (GWS) on all current and future DDG 51 Flight IIA and Flight III Destroyers is the fastest and most cost-effective way to field critical C-UAS ship self-defense capability.

FY2027 planned work - Complete and certify 30mm airburst round integration into the 30mm MK 38 MOD 4 MGS. - Begin development of a "nonintegrated/stand-alone" design of the MK 38 MOD 4 MGS to support installation on FLT II DDGs and USCG platforms.

FY2026 to FY2027 change Decrease from FY26 to FY27 ($0.071 million) is due to decreased funding required to support 30mm airburst round integration completion and certification efforts.

FY2026 plans — current year - Continue 30mm airburst round integration development efforts to incorporate additional functionality into the 30mm MK 38 MOD 4 GWS to increase effectiveness against Unmanned Aerial Systems (UAS) and Unmanned Surface Vehicle (USV).

Mission & acquisition strategy

Project 2038: The 25mm MK 38 MOD 2 and MOD 3 Machine Gun Systems (MGS) provide Anti-Surface Warfare (ASUW) and Anti-terrorism and Force Protection (AT/FP) capability as a simple, stabilized, low cost solution to outfit near-term deployers to counter small boat threats.

The Advanced Minor Caliber Gun program procures developmental engineering and technical services from Naval Surface Warfare Center (NSWC) Dahlgren to support MK340 30mm airburst round integration capability improvement for MK 38 MOD 4 GWS to increase effectiveness against Unmanned Aerial Systems (UAS) and Unmanned Surface Vehicle (USV).
