Lockheed Martin Corporation is an American armaments and technology group that is primarily active in the military, civil aviation and aerospace industries. Nearly 80% of the $46 billion in revenue in 2014 was generated from purchases by the United States government.

Lockheed Martin Corporation was founded in March 1995 and is a merger of Lockheed Corporation and Martin Marietta Corporation. In 1996, Loral Corporation was bought for $9.1 billion. As a result of the merger and severe financial problems in the late 1990s, large parts of the group were sold to the British competitor BAE Systems. BAE Systems temporarily replaced Lockheed Martin as the largest armaments company in the world. After an extensive renovation, Lockheed Martin was able to claim this title again in 2004.
