Lockheed Martin Delivers 50th C-5 AMP Aircraft

MARIETTA, Ga., April 29 /PRNewswire-FirstCall/ -- 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.

Headquartered in Bethesda, Md., Lockheed Martin is a global security company
that employs about 146,000 people worldwide and is principally engaged in the
research, design, development, manufacture, integration and sustainment of
advanced technology systems, products and services. The corporation reported
2008 sales of $42.7 billion.
