Coast Guard Accepts 18th Mission-Ready HC-130J for Sacramento Fleet Expansion

The United States Coast Guard is finalizing delivery activities this week for its 18th fully missionized HC-130J Super Hercules long-range surveillance aircraft. According to an official announcement from the service, the military-aircraft, designated CGNR 2018, is being accepted at the L3Harris Integrated Mission Systems facility in Waco, Texas.

This delivery marks the culmination of a complex two-stage procurement process. While the “green” (baseline) aircraft was originally delivered by manufacturers Lockheed Martin in January 2025, it has spent the last year undergoing specialized “missionization” upgrades. These modifications transform the standard transport airframe into a sophisticated surveillance asset capable of executing the Coast Guard’s diverse maritime missions.

The acceptance of CGNR 2018 is a critical step in the service’s recapitalization efforts. This specific airframe is slated to support the transition of Air Station Sacramento, California, which is shifting from the smaller C-27J Spartan to the larger, more capable HC-130J platform.

The Missionization Process

The journey from a factory-fresh aircraft to a deployable Coast Guard asset involves significant technological integration. According to the Coast Guard’s acquisition directorate, the aircraft underwent approximately one year of modifications at the L3Harris facility in Waco. This process integrates the service’s proprietary systems into the commercial airframe.

Key upgrades installed during this period include the Minotaur Mission System Suite. This government-owned, open-architecture system acts as the central nervous system of the aircraft, integrating sensors, Radar-Systems, and communications equipment. It allows crew members to gather and process surveillance data in real-time, a vital capability for search and rescue (SAR) and interdiction operations.

Technical Enhancements

In addition to the Minotaur suite, the missionization process equips the Super Hercules with the AN/APY-11 Multimode Radar, designed to track maritime targets even in high seas and adverse weather conditions. The aircraft also received the Block 8.1 upgrade, which includes enhanced inter-communication systems, improved approach and landing capabilities, civil GPS integration, and expanded diagnostic tools.

Strategic Deployment and Funding

The delivery of CGNR 2018 is part of a broader strategy to modernize the Coast Guard’s fixed-wing fleet. The service plans to acquire a fleet of at least 22 HC-130Js to replace the aging legacy HC-130H models. The new J-models offer significant performance improvements, including a 20 percent increase in speed and a 40 percent increase in range compared to their predecessors.

This procurement is supported by substantial legislative investment. According to background research on recent appropriations, the funding for this aircraft stems from the “One Big Beautiful Bill Act” (OBBBA), signed in July 2025. This legislative package allocated approximately $25 billion to the Coast Guard, with $1.1 billion specifically designated for the procurement of six HC-130J aircraft and associated simulators.

AirPro News Analysis

The assignment of CGNR 2018 to Air Station Sacramento represents a significant shift in West Coast maritime capability. By transitioning from the C-27J Spartan to the HC-130J, the station will gain the ability to conduct longer patrols further offshore. The HC-130J’s range of approximately 4,900 nautical miles and endurance of over 20 hours will allow for extended search and rescue operations deep into the Pacific, a capability that is increasingly vital as maritime traffic and operational demands grow. We view this as a strategic consolidation of heavy airlift and surveillance resources on the Pacific Rim.

Frequently Asked Questions

What is the difference between the “green” delivery and the final delivery?

The “green” delivery refers to the handover of the basic airframe from the manufacturer (Lockheed Martin). The final delivery occurs after the aircraft has been outfitted with specific Coast Guard sensors and mission systems by a contractor (L3Harris).

Where will the new aircraft be based?

CGNR 2018 is scheduled to operate out of Air Station Sacramento, California.

How does the HC-130J compare to the older H-model?

The J-model features advanced engines and avionics, providing a 20% increase in speed and a 40% increase in operational range over the legacy HC-130H.
