US Navy Awards $3.5 Billion Contract for E-130J TACAMO Next-Gen Communication Aircraft.

The U.S. Navy has awarded Northrop Grumman Corporation a $3.5 billion contract to develop and integrate mission systems for the E-130J, a next-generation airborne communication aircraft designed to replace the E-6B Mercury in the critical Take Charge and Move Out (TACAMO) role. This development, announced on December 18, 2024, highlights the Navy’s commitment to modernizing its airborne nuclear command, control, and communications (NC3) capabilities as part of a broader nuclear modernization effort.

The E-130J, based on the Lockheed Martin C-130J-30 Super Hercules airframe, will serve as a survivable airborne communication link, ensuring continuous connectivity between U.S. leadership and nuclear forces in scenarios where ground-based communications are compromised. Northrop Grumman, headquartered in Melbourne, Florida, will lead the program, integrating advanced mission systems such as Collins Aerospace’s Very Low Frequency (VLF) communications system. Lockheed Martin and Collins Aerospace are directed subcontractors responsible for airframe production and system integration.

The contract covers the creation of three Engineering Development Models (EDMs), with options for three System Demonstration Test Articles (SDTAs) and six aircraft in the initial production lot. Work begins immediately, with delivery of the first aircraft anticipated by 2026, supporting the U.S. Navy’s objective to begin replacing the aging E-6B Mercury fleet by Fiscal Year 2028.

The E-130J’s design incorporates the proven reliability of the C-130J-30 platform, featuring a length of approximately 30 meters (98 feet) and a wingspan of 41 meters (133 feet). It is powered by four Rolls-Royce AE 2100D3 turboprop engines, each delivering 3,430 kilowatts (4,600 horsepower). With a maximum speed of 670 km/h (362 knots or 417 mph) and a service ceiling of 8,534 meters (28,000 feet), the E-130J is well-suited to meet the rigorous demands of the TACAMO mission. It also integrates cutting-edge systems, including advanced secure communication technologies, to ensure survivability and reliability in high-threat environments.

The current TACAMO platform, the E-6B Mercury, performs dual roles: maintaining secure communications with nuclear forces and serving as an airborne launch control center for intercontinental ballistic missiles. The E-130J will take over the TACAMO mission, allowing the E-6B to focus on other responsibilities, including the Looking Glass mission.

This modernization initiative aligns with the United States’ broader efforts to enhance its nuclear deterrence capabilities, which also include the development of Columbia-class ballistic missile submarines, B-21 Raider bombers, and the Sentinel intercontinental ballistic missile system. The E-130J’s role is critical in maintaining the resilience and responsiveness of the nation’s nuclear command structure, ensuring national leaders can issue commands under any circumstances.

The program is managed by the Navy’s Airborne Strategic Command, Control, and Communications Program Office (PMA-271), based at Naval Air Station Patuxent River, Maryland. The office oversees the development and deployment of survivable and reliable airborne NC3 systems.

The E-130J’s induction will mark a significant advancement in the Navy’s capabilities, ensuring that the TACAMO mission continues to provide an unbroken link between national leaders and strategic forces, reinforcing the U.S. deterrence posture and national security objectives.
