Comms Problems Hold Up C-130J Deliveries

The Air Force is delaying deliveries of new C-130J Super Hercules aircraft amid problems with obsolete components and new communications equipment, industry and service officials say.

“The U.S. Air Force, in partnership with our industry counterparts, is working to resolve a technical issue identified during the integration of a new communications suite on the C-130J production line to address obsolete components,” according to an Air Force spokesperson. “Our engineering teams are working closely with Lockheed Martin to test and certify the solution.”

The Air Force issue involves component incompatibility discovered during testing.

A Lockheed spokesperson told Air & Space Forces Magazine on Feb. 11 that in 2025 the company integrated a new communication suite into the C-130J production line because of obsolete components.

“We are finalizing certification of the new C-130 implementation design with our customers and plan to resume deliveries soon, projecting between 16-24 aircraft this year,” the Lockheed spokesperson said.

Lockheed emphasized that aircraft production never stopped.

Aviation Week first reported the delivery pause, saying only two C-130Js were delivered in 2025. Lockheed did not confirm that assessment.

“Aircraft deliveries are temporarily paused to ensure every C-130J meets rigorous safety, performance and airworthiness standards required before the U.S. government can accept them,” the Air Force spokesperson wrote in an email. Aircraft deliveries will resume once required testing and certifications are completed, the spokesperson noted.

Neither the Air Force nor Lockheed described the obsolete part or parts, the timeline for the problem to be resolved, or how many aircraft have been delayed.

The C-130J is the latest variant of a decades-old aircraft used for a variety of missions. Some of those missions include tactical, intertheater airlift, airdrop, and wildfire suppression. The aircraft first deployed to combat in 2004.

Compared with the C-130H, the J variant, or Super Hercules, can fly faster, higher, and farther. The C-130J-30 version features a “stretched” fuselage that is 15 feet longer than standard.

Budget documents from June 2025 show the Air Force planned to operate 179 C-130Js in fiscal year 2026, up from 165 the previous year.

In 2020, the Pentagon announced a multiyear contract worth $3 billion to deliver 50 C-130Js to the Air Force, Marine Corps, and Coast Guard, according to a Lockheed release at the time. Deliveries were planned for between 2021-2025.

In December, the Pentagon increased a contract related to C-130J development and engineering for foreign military sales to Germany, Norway, the Philippines, France, New Zealand, Australia and Egypt, to a total ceiling value of $20 billion.
