06:36 GMT, April 30, 2009 MARIETTA, Ga. | Lockheed Martin [NYSE: LMT] recently delivered the 50th C-5 Galaxy strategic airlifter upgraded with Avionics Modernization Program (AMP) improvements. AMP is the first part of the two-phase C-5 modernization program. The aircraft, delivered to Air Force Reserve Command’s 433rd Airlift Wing at Lackland AFB, Texas, is now equipped with a state-of-the-art glass cockpit with modern avionics and flight instruments.

"This delivery brings the Air Force one step closer to realizing the full capability of an upgraded and more efficient C-5 fleet," said Lorraine Martin, Lockheed Martin C-5 program vice president. "We’re currently running two very successful AMP production lines. This effort, along with the upcoming second phase of the C-5 modernization program, will ensure the Air Force has a C-5 fleet that will be highly effective for the next 40 years."

The AMP installations are taking place at Dover AFB, Del., and at Travis AFB, Calif. The fleet-wide AMP modifications are scheduled to be completed in the second quarter of 2014. A total of 111 C-5s are scheduled to be modified with AMP upgrades.

The AMP upgrades replace the analog cockpit instruments and systems in the C-5 with digital displays and equipment. This modernization phase also provides the necessary communications and navigational avionics to comply with Global Air Traffic Management (GATM) requirements, the new set of international standards for aircraft movement and reduced separation in flight.

The second phase of the C-5 modernization effort is the Reliability Enhancement and Re-Engining Program (RERP). RERP includes 70 enhancements or replacements of major components and subsystems, including the installation of GE CF6-80C2 commercial engines. Fifty-two of the 111 airplanes receiving the AMP upgrades are currently scheduled to receive the RERP upgrades. When one of the giant transport aircraft receives both the AMP and RERP modifications, it receives the C-5M Super Galaxy designation. Three aircraft (two former B-models and one former A-model) were used as the C-5M test fleet. All three of the C-5M aircraft have been delivered back to the U.S. Air Force.

The C-5 has been the backbone of strategic airlift in every military and humanitarian engagement since it entered service. It is the only aircraft capable of carrying 100 percent of certified military air-transportable cargo with a dedicated passenger compartment enabling commanders to have troops and their equipment arrive simultaneously in an area of operation. The C-5 can carry twice the cargo of other strategic airlift systems, and the C-5M Super Galaxy will be a force multiplier through 2040. Modernization of the C-5 pays for itself through savings in operation and sustainment costs.
