Asked vs spent: the PB2024 book requested $114.3M for FY2024; the PB2026 book reported $124.2M as actual total obligation authority — $9.92M above the request. 124.2 − 114.3 = 9.9 USD millions — the compact figures above are rounded for reading.

Description
Description — H-1 Series
This line item funds modifications to the UH-1Y and AH-1Z aircraft and related systems. This budget line item is aligned with the Marine Corps' top three H-1 Upgrades priorities of Digital Interoperability (DI), improve survivability, and increase lethality while enabling future capability improvements, addressing obsolescence, and improving reliability. Modifications also improve readiness, increase aircraft availability, and decrease operating costs. Reliability improvements and obsolescence management will reduce flight hour costs, maintain/increase operational capability, and increase time on wing. Improvements include software upgrades and integration test assets to support engineering modifications. The mission of the UH-1Y utility helicopter is to provide combat assault, offensive air support, and command and control under day/night and adverse weather conditions and special operations support such as supporting arms coordination and casualty evacuation. UH-1Y is crewed by two pilots and two crew chiefs with max capacity of 12 personnel. The mission of the AH-1Z attack helicopter is to provide offensive air support, anti-armor, armed escort, armed/visual reconnaissance, anti-helicopter and point air defense and fire support coordination during day/night conditions. Current armament includes the Sidewinder and Hellfire missiles, Joint Air-to-Ground Missile (JAGM), a chin-mounted 20mm turret, and a wide variety of forward-firing and gravity-released external stores. AH-1Z is a tandem, two-seat attack helicopter. OSIP 15-12: OSIP incorporates modifications to H-1 avionics systems, for instance; Digital Interoperability (DI), line of sight communications, over the horizon communications, and mission computers. DI provides Maritime Multi-Domain awareness/Kill-web enabler and effector, facilitates command and control, H-1 air-to-air/air-to-ground shore based and maritime information sharing, shortens the kill chain, and improves battlefield information and intelligence sharing. DI incorporates a family of systems that includes ANW-2 (Adaptive Network Wideband Waveform), ADTS (Advanced Data Transfer System), FMV (Full Motion Video), RFID (Radio Frequency Identification) and CDS (Cross Domain Solution). Link-16 provides Maritime Multi-Domain awareness / Kill-web enabler and effector, facilitates command and control, H-1 air-to-air / air-to-ground shore based and maritime information sharing, shortens the kill chain, and improves battlefield information and intelligence sharing. Improvements leverage common architectures and existing technology to minimize development costs, procurement costs, and fielding time. Mission computer (the "brains" of the aircraft that provide pilot control of aircraft systems) addresses obsolescence and capability improvements and is an enabler to APR-39D(V)2, Link-16, and Joint Air-to Ground Missile (JAGM). OSIP 16-12: OSIP incorporates APR-39D(V)2 integration and obsolescence mitigation to the Target Sight System (TSS) in support of USMC Joint Air-to Ground Missile, (JAGM), capability. APR-39D(V)2 increases aircraft survivability against proliferated threats and replaces the obsolete APR39B(V)2 system. OSIP 13-14: OSIP incorporates modifications to Air Vehicle systems, specifically attacking enablers for avionics, sensors, and weapons systems and the highest readiness degraders. Funds are required to improve aircraft elements such as component reliability of the main gearbox system, tail rotor drive system, thermal and electrical power management, drive plate, fuel system, floorboards, and combining gearbox, reducing sustainment costs, improving maintainability, increasing safety, and extend aircraft component life limit. OSIP 12-24: OSIP incorporates the H-1 Structural Improvement and Electrical Power Upgrades (SIEPU) project, which addresses critical safety and performance shortfalls to the existing AH-1Z and UH-1Y airframes and electrical systems. Funds are required to modify electrical systems in the UH-1Y and AH-1Z to increase the electrical capacity and enable digital architecture capability improvements, as well as to address multiple structural safety concerns in the UH-1Y cockpit. Aircraft inventory objectives for FY 2026: 133 UH-1Y aircraft; 168 AH-1Z aircraft.
Justification
Justification — H-1 Series
FY 2026 budget request prioritizes procurement of systems or enablers related to the top three Marine Corps priorities for H-1: DI (Link-16), survivability (APR-39 D(V)2), and lethality (enabler - Structural Improvement and Electrical Power Upgrade (SIEPU)). Improvements to safety of flight, maintenance, obsolescence (Diminishing Manufacturing Sources/Material Shortages), aircrew situational awareness and readiness degrader items yield a more interoperable and survivable H-1 force. Systems improved on H-1 aircraft leverage common avionics architectures to mitigate development costs, procurement costs, and reduce fielding timelines while attacking the highest readiness degraders and improve readiness rates. The FY 2026 request was reduced by $1.531 million for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." The FY 2026 request was reduced by $1.432 million for civilian personnel to optimize the workforce in compliance with Executive Order 14210, "Implementing the President's Department of Government Efficiency Workforce Optimization Initiative."

Contractor concentration
High-confidence award links only, pooled across ingested years. The index uses positive obligations; program obligations are net of deobligations. The figures over every published link, including medium-confidence ones, are in the downloadable warehouse, not on this page — why.
Lobbying mentions
No Senate LDA lobbying filing in the tracked data mentions this program element by code or alias.
Oversight
Department-level designation (not specific to this program)
GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not H-1 Series. No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
