The USAF has awarded an ongoing fund of $344m to Lockheed to provide continued support for the C-5 Super Galaxy reliability enhancement and re-engining programme (RERP).
Lockheed has received the contract through an acquisition decision memorandum (ADM) that authorises low -rate initial production (LRIP).
As part of the contract, Lockheed will support LRIP RERP production for 15 aircraft, perform installation on three aircraft, material and fabrication for five aircraft, and long-lead funding for seven aircraft.
A strategic airlifter, the C-5 carries 100% of certified air-transportable cargo, and has a dedicated passenger compartment that enables troops and their equipment to drop in an area of operation simultaneously.
The C-5M, developed from a two-phase modernisation effort, can carry twice the cargo of other strategic airlift systems.
The ongoing avionics modernisation programme, the first modernisation effort, will equip the aircraft with a state-of-the-art glass cockpit with modern avionics and flight instruments.
The RERP, the second modernisation effort, includes 70 enhancements or replacements of major components and subsystems, including the installation of GE CF6-80C2 commercial engines.
The C-5 modernisation programme aims to save operation as well as sustainment costs.
The USAF will receive the C-5M Super Galaxy in September 2010.
The air force has already received three C-5Ms, and plans to receive additional 52 fully-modernised C-5Ms by 2016.
