The US Air Force Life Cycle Management Center (AFLCMC) has announced that the Mobility and Training Aircraft Directorate has awarded an alternate modification installation (AMI) contract for the installation of ‘avionic modifications’ on the C-5 Galaxy fleet of aircraft.

Valued at $92.8m, the contract has been awarded to Tyonek Native Corporation.

AFLCMC noted that the modifications are designed to improve the performance and effectiveness of the aircraft.

As part of the modifications programme, upgradation will be made to the C-5 fleet’s Core Mission Computer and Color Weather Radar (CMC/WxR) system, the Communications, Navigation, Surveillance, and Air Traffic Management (CNS/ATM) system, and the Pylon Hydraulic Check Values.

Furthermore, the large aircraft infrared countermeasures system (LAIRCM) onboard will receive the Block 30 upgrade.

The C-5M Super Galaxy strategic transport aircraft is a modernised version of the legacy C-5.

It was designed and manufactured by Lockheed Martin to extend the capability of the C-5 Galaxy fleet to remain in service at least until 2040.

Mobility and Training Aircraft Directorate AMI programme manager Captain Denzel Varnado said: “This contract is a big deal. This contract ensures that we are not only able to get the warfighter these upgraded weapon systems [C-5s] quickly, but to also have the flexibility to make changes as required.

“These advantages are a huge win for the C-5 platform and our troops. As the Air Force becomes more agile, a contract like this will play a key role in our success.”

According to AFLCMC, the AMI contract is designed to focus on avionics, electrical and mechanical modifications as opposed to ‘structural modifications’, which will be left to depots.

Furthermore, the contract is designed to reduce the time taken to install modifications to get the aircraft back into the field and support worldwide operations.

Two C-5s have received the modifications before the AMI contract.

The remaining 50 aircraft in the C-5 fleet are expected to be modified starting from June this year and conclude by July 2025.
