Anaheim, Calif., 05/20/2008 -- Lockheed Martin [NYSE: LMT] announced today that it has provided a grant to the Smithsonian's National Postal Museum for Mail Call, a new permanent exhibit devoted to the history of mail during times of conflict. The exhibit is part of a major renovation of the museum's history-themed galleries and is expected to open in 2010 - 2011.

On the battlefront and at home, mail helps sustain vital connections between military service members, their families and friends, said National Postal Museum Director Allen Kane. Now, with this very generous gift from Lockheed Martin, National Postal Museum visitors can explore 'Mail Call' to learn about the extraordinary efforts to move mail to and within war zones and view poignant letters of military personnel and their loved ones.

Since opening in 1993, the National Postal Museum has consistently devoted exhibition space to highlight the dramatic history of mail communications during America's conflicts. Mail Call will offer a first-hand look at the American experience - from the Colonial era to current events - as seen through vivid personal letters and mail operations in times of conflict.

We understand the tremendous effort both the U.S. Postal Service and our armed forces undertake to keep American service members connected with their loved ones, and we are honored to help the National Postal Museum share that with the public, said Lockheed Martin Global Delivery Services Vice President Carla Powe. From logistics and technology to timeliness and security, delivering mail during times of conflict is an intricate and challenging process.

Lockheed Martin is also a sponsor of the Systems At Work exhibit, another one of the seven new exhibits planned by the museum to showcase the history and future of the postal museum. Systems At Work will showcase technological advances from the colonial past to the present day and explain the workings of a complex network of mail processing and distribution.
