SUNNYVALE, Calif., Nov. 14, 2012 /PRNewswire/ --The U.S. Air Force and
Lockheed Martin (NYSE: LMT) have completed on-orbit testing of the second
Advanced Extremely High Frequency (AEHF) military communications satellite.
Following successful spacecraft testing, Satellite Control Authority (SCA) was
turned over to the 14^th Air Force at Vandenberg Air Force Base, Calif., for

The AEHF system provides vastly improved global, survivable, highly secure,
protected communications for strategic command and tactical warfighters
operating on ground, sea and air platforms. The system also serves
international partners including Canada, the Netherlands and the United

A single AEHF satellite provides greater total capacity than the entire legacy
five-satellite Milstar constellation. Individual user data rates will be
increased five-fold, permitting transmission of tactical military
communications, such as real-time video, battlefield maps and targeting data.
In addition to its tactical mission, AEHF also provides the critical
survivable, protected, and endurable communications links to national leaders
including presidential conferencing in all levels of conflict.

"Completion of on-orbit testing and handover of AEHF-2 is a critical milestone
for the Air Force and our nation," said Dave Madden, Director of the Military
Satellite Communications Systems Directorate at the U.S. Air Force's Space and
Missile Systems Center. "The AEHF satellites on orbit and those planned for
launch will play a pivotal role in our national security for years to come."

AEHF-2 launched May 4, 2012 aboard a United Launch Alliance Atlas V rocket.
After successful spacecraft deployments and payload activation, the satellite
has now completed all on-orbit testing. The on-orbit testing demonstrated
both interoperability with the existing Milstar constellation and established
communications networks between combinations of EHF communications terminals
with legacy Milstar data rates, as well as at the new AEHF extended data rates

"The U.S. Air Force, Lockheed Martin and Northrop Grumman AEHF team performed
a thorough and efficient on orbit test campaign for this critical satellite,
and AEHF-2 is performing exceptionally well," said Mark Calassa, Lockheed
Martin's vice president and AEHF program manager. "With the first two AEHF
satellites now on orbit, the Department of Defense is well on its way to
augmenting, improving and expanding its critical military satellite
communications architecture to meet increasing demand from users worldwide."

Lockheed Martin is currently under contract to deliver four AEHF satellites
and the Mission Control Segment. The program has begun advanced procurement
of long-lead components for the fifth and sixth AEHF satellites.

AEHF-1 and AEHF-2 have both launched and are on orbit. Lockheed Martin has
completed work on AEHF-3 and will prepare the satellite for a September 2013
launch date.

The AEHF team includes the U.S. Air Force Military Satellite Communications
Systems Directorate at the Space and Missile Systems Center, Los Angeles Air
Force Base, Calif. Lockheed Martin Space Systems Company, Sunnyvale, Calif.,
is the AEHF prime contractor, space and ground segments provider as well as
system integrator, with Northrop Grumman Aerospace Systems, Redondo Beach,
Calif., as the payload provider.

Headquartered in Bethesda, Md., Lockheed Martin is a global security and
aerospace company that employs about 120,000 people worldwide and is
principally engaged in the research, design, development, manufacture,
integration and sustainment of advanced technology systems, products and
services. The corporation's net sales for 2011 were $46.5 billion.
