HitchAI read

U.S. Navy funding ramps 134% to a $522.0M request in FY2027 — the program's peak, before stepping down 70% across the five-year plan. In the FY2027 defense authorization, the House cut 3.8% (to $502.0M); the Senate funded it in full; House appropriators cut 31% (to $361.2M). General Dynamics leads the industry work.

Mission & acquisition strategy

This PE is fundamentally a crucial "try before you buy" initiative for the Marine Corps' entire arsenal of ground combat and fire support systems. Its core purpose is to rigorously test, experiment with, and ultimately validate new or upgraded weapons and equipment in the most realistic scenarios possible before the Corps commits to a massive investment in full-scale production and fielding. This meticulous process ensures that every piece of gear eventually placed into the hands of a Marine is not only lethal and effective but also entirely reliable and perfectly suited for their unique mission, thereby safeguarding lives and taxpayer dollars by preemptively avoiding costly failures.

The LRUSV program used an incremental approach to develop capabilities that integrate vessels, autonomy packages, and sensor platforms in support of Marine Corps objectives. The Marine Corps integrated, tested, and verified different sized vessel platforms, autonomy packages, and sensor platforms to determine capability requirement feasibility, assess technical maturity, and refine the concept of employment. With the assistance of Naval Surface Warfare Center Carderock, the LRUSV program conducted risk reduction development and test activities supporting manned/unmanned teaming concepts and sea-based command and control (C2) of the LRUSV to inform future requirements of an unmanned surface vessel.

What project 1558 buys

The Advanced Reconnaissance Vehicle (ARV) program is designed to fill a pressing operational need with the Marine Corps portfolio of reconnaissance, surveillance, and target acquisition systems. The ARV will be a purpose-built combat system, highly mobile on land and water, that can sense, communicate, and fight in the performance of reconnaissance and battlespace shaping activities. Equipped with modern command, control, communications, and surveillance systems the ARV will transform the ability of Fleet Marine Forces to sense and communicate within the littoral operating environment by providing a persistent and mobile systems of systems to augment and sustain effective sensor webs and kill chains. The base program will consist of the following mission role variants (MRV): ARV-30mm (ARV-30), ARV-Command, Control, Communications and Computers/Unmanned Aerial Systems (C4UAS) and ARV-Logistics (LOG). The complete family of systems capability is planned to consist of 3 additional mission role variants with initiation in FY 2028: ARV-Recovery (R), ARV-Precision Fires (PF) and ARV-Counter Unmanned Aerial System (CUAS).

What project 6639 buys

This line develops a Multiple Launch Rocket System (MLRS) Family of Munitions (MFOM) Launcher Unit (MLU). The MLU will interface with Medium-range Missile (MMSL) Remotely Operated Ground Unit for Expeditionary Fires (ROGUE-Fires) carriers providing the additional capability to fire the entire complement of MFOM. This modular capability is an essential element of the Marine Corps artillery modernization strategy as it affords operational flexibility for the artillery regiments and Marine Littoral Regiments (MLR) to utilize Navy/Marine Expeditionary Ship Interdiction System (NMESIS) or MLU. The MLU will consist of a MLU sled (launch unit with a Common Fire Control System (CFCS)) and a weapon control system (Remote Gunner Station (RGS)). The RGS is a modular, scalable tablet that can be operated from a Mobile Command Vehicle as well as from a command post and is being adapted to control up to three MLUs per section. The MLU sled will be mounted upon a ground-based, tele-operated carrier (ROGUE-Fires) and will be capable of firing Guided Multiple Launch Rocket System (GMLRS), Reduced Range Practice Rocket (RRPR), Precision Strike Missile (PrSM) series, and other MFOM-related munitions that the HIMARS platform can accommodate. A ROGUE-Fires leader-follower kit will be capable of steering up to three systems. This effort includes design, development, integration, and test of the MLU and RGS for interface with the ROGUE-Fires carrier. The MLU makes extensive use of existing systems to increase operational flexibility and reduce procurement and product support. FY 2026 completed the development of one-to-one radio-controlled operations, continued development for the one-to-three radio-controlled operations of the MLU, purchased test assets, and conducted developmental testing. FY 2027 completes the development of the one-to-three radio-controlled MLU operations and conducts testing.

What project 7400 buys

The Marine Corps is establishing a new Maritime Reconnaissance Company (MRC) unit as part of the broader evolution of our light armored reconnaissance (LAR) battalions into mobile reconnaissance battalions (MRBs). The MRC will operate a new tactical boat, the Multi-Mission Reconnaissance Craft (MMRC), which can partner with unmanned systems to maneuver sensors and personnel in support of Marine forces operating in the littorals. Long Range Unmanned Surface Vessel (LRUSV) was an unmanned, semi-autonomous platform capable of multi-domain sensor collections that enabled the Marine Littoral Regiment / Marine Expeditionary Force to enhance Maritime Domain Awareness (MDA) for the Joint Force. LRUSV employed a suite of organic sensors (RADAR, EO/IR, and Electromagnetic Support) to accomplish its primary function of gaining and maintaining custody of surface contacts of interest in the littoral operating environment. LRUSV sensor capabilities assisted the Marine Division's Maritime Reconnaissance Company in its mission to conduct seaward Reconnaissance, Surveillance, and Target Acquisition (RSTA) in a peer-threat contested, littoral operating environment across the spectrum of competition, crisis, and conflict to enhance Joint and coalition MDA and facilitate the application of organic and Joint fires. Multi-Mission Reconnaissance Craft (MMRC) is a manned vessel, which when teamed with unmanned systems, will enable the stand-in force to use the sea as maneuver space, exploiting the predominate terrain in the littoral environment to extend their RSTA capabilities beyond the limitations of land-based systems. The capability will provide a persistent, fused, all weather maritime domain awareness collections capability that enables over-the-horizon (OTH) targeting and facilitates the application of organic and Joint fires. Additionally, the MMRC will insert and extract teams across challenging open water distances, emplace/recover sensors, and provide a stable, protected platform to maneuver specialist capabilities to seaward. In FY 2026, LRUSV implemented and completed sensor enhancements, conducted smaller form factor USV developmental testing, and completed facilities studies. Based on the completion of the LRUSV effort, in FY 2027 the Marine Corps is shifting focus to a manned MMRC platform.
