Lockheed Martin has received the US Air Force’s (USAF) C-5B Galaxy aircraft for its planned modernisation, as part of the reliability enhancement and re-engining programme (RERP).
The aircraft will be modified to to C-5M Super Galaxy standard, the largest airlift aircraft in the US Air Force fleet. The C-5B is the 12th aircraft to undergo the process.
The RERP modifications consist of more than 70 improvements and upgrades to the C-5 airframe and aircraft systems, with improvements including the installation of new higher-thrust, turbofan engines.
The USAF has recently taken delivery of the 79th and final C-5 Galaxy aircraft from Lockheed, following completion of the avionics modernization program (AMP).
Implemented in 1998, the AMP is the first part of a two-step CM-5 modernisation programme, aimed at providing increased reliability, maintainability and better fuel efficiency to the aircraft, while also extending its service life beyond 2040.
