HC/MC-130 Recap RDT&E

The HC/MC-130 Recap RDT&E program is a Research, Development, Test, and Evaluation (RDT&E) initiative managed by the U.S. Air Force under Budget Activity 7, Operational Systems Development. Its primary goal is to modernize and recapitalize the Air Force's medium-lift tanker fleet, specifically the HC-130J, MC-130J, and AC-130J aircraft, which are essential for Combat Search and Rescue (CSAR) and Special Operations Forces (SOF) missions. The program addresses airworthiness, maintainability, and operational limitations of aging aircraft by integrating advanced mission systems and production line modifications into the C-130J platform. This ensures a common baseline configuration and enhances mission effectiveness in contested environments.

HC-130J Modernization is a key line item within this program, focusing on the lifecycle development and installation of upgrades for the HC-130J fleet. The objectives include continuous software and hardware enhancements through the Continuous Improvement Program (CIP), development and integration of electronic warfare capabilities, airborne battle management, and upgraded Link-16 connectivity. These efforts are designed to maintain fleet viability against emerging threats and to resolve deficiency reports. The modernization activities also support rapid acquisition authorities, enabling the Air Force to respond quickly to new requirements and threats as they arise.

Communication Modernization is another major component, aimed at ensuring compliance with Department of Defense (DoD) Cryptographic Modernization Mandates. This project is divided into two phases. Phase I focuses on integrating Mobile User Objective System (MUOS) and VINSON/ANDVT Cryptographic Modernization (VACM), enabling secure voice, data, video, and satellite communications. Phase II addresses Second-generation Anti-jam Tactical UHF Radio for NATO (SATURN), Single Channel Ground and Airborne Radio System (SINCGARS), and High Frequency (HF) Modernization to resolve Diminishing Manufacturing Sources (DMS) issues. These upgrades are critical for maintaining secure and resilient communications in real-time across UHF, VHF, and HF bands.

The Resilient Positioning, Navigation, and Timing (R-PNT) initiative within Communication Modernization seeks to provide reliable and accurate navigation and timing solutions for the HC/MC-130 fleet. R-PNT development includes integrating hardware and software to enable operations in GPS-degraded or denied environments, supporting precision fires and time coordination, and countering electronic and cyber threats. This capability is essential for uncompromised CSAR and SOF infiltration/exfiltration operations in contested environments and aligns with Chief of Staff of the Air Force (CSAF) Capability Development Guidance.

STAR XIII Mission Computer is a new start effort under Communication Modernization, intended to replace the legacy STAR IX Mission Computer due to diminishing manufacturing sources. The program funds the development, verification, and certification of software releases to ensure interoperability with the AC/HC/MC-130J fleet. Activities include trial kit installation, development testing, and product support package validation, which are necessary for future production and fielding. This upgrade is critical for maintaining mission computer capability and supporting evolving operational requirements.

Across all line items, the HC/MC-130 Recap RDT&E program supports innovation activities such as studies, analyses, requirements definition, and quick-reaction capability prototypes. These efforts accelerate technology transition, insertion, and future acquisition planning. The program also covers integration and certification for Diminishing Manufacturing Sources Materiel Solutions (DMSMS) and supports continuous improvement to keep the fleet effective against emerging threats. Civilian pay expenses and contractor support are included to ensure effective program management and execution.
