High performance jet fighters have used a variety of morphing mechanisms in the past such as variable-sweep wings and fowler flaps to expand the flight envelope. Lockheed Martin (NYSE: LMT) is a leading multinational aerospace manufacturer and advanced technology company formed in 1995 by the merger of Lockheed Corporation with Martin Marietta. It is headquartered in Bethesda, Maryland, a community in Montgomery County, Maryland, and employs 140,000 people worldwide. Robert J. Stevens is the current Chairman, President, and Chief Executive Officer.Lockheed Martin is the world's largest defense contractor (by revenue). As of 2005, 95% of Lockheed Martin's revenues came from the United States Department of Defense, other U.S. federal government agencies, and foreign military customers.A team led by prime contractor Lockheed Martin won the 2006 Collier Trophy for the development of the F-22 Raptor fighter jet. The Collier Trophy is the highest award in the aviation industry.Lockheed Martin was formed by a "merger of equals", both companies contributing important products to the new portfolio. Lockheed products included the Trident missile, P-3 Orion, F-16 Fighting Falcon (the production line being purchased from General Dynamics in 1993), F-22 Raptor, C-130 Hercules, A-4AR Fightinghawk and the DSCS-3 satellite. Martin Marietta products included Titan rockets, Sandia National Laboratories (management contract acquired in 1993), Space Shuttle External Tank, Viking 1 and Viking 2 landers, the Transfer Orbit Stage (under subcontract to Orbital Sciences Corporation) and various satellite models. Six companies not kept after the merger became the foundation for today's L-3 Communications, a mid-sized defense contractor in its own right.Shortly after the creation of the company Lockheed Martin acquired the majority of Loral Corporation's defense electronics and system integration businesses for $9.1 billion. The remainder of Loral became Loral Space & Communications.In 1998, Lockheed Martin abandoned plans to merge with Northrop Grumman due to government concerns over the potential strength of the new group (Lockheed/Northrop would have had control of 25% of the Department of Defense's procurement budget).In September 1999, the Mars Climate Orbiter smashed into the surface of Mars and was destroyed due to a failure to convert imperial measures of rocket thrust (pounds) to metric measures (Newtons). Lockheed Martin, the prime contractor for the mission, measured the thruster firings in pounds, even though the National Aeronautics and Space Administration had requested metric measurements. The $250 million dollar spacecraft burned up or broke apart in the Mars' atmosphere due to the error. Lockheed accepted blame for the demise of the craft after an investigation revealed that the Lockheed team incorrectly programmed the Mars Climate Orbiter with English units instead of metric units.In 2000, Lockheed agreed to pay a $13 million settlement to the U.S. government for breaching the arms export control act. The company passed information to AsiaSat, of which a major shareholder is the Chinese government. According to the U.S. Department of State, the information given to AsiaSat may have helped China improve its missiles. In May 2000, Lockheed Martin sold Lockheed Martin Control Systems to BAE Systems. In November 2000, Lockheed completed the sale of its Aerospace Electronic Systems business to BAE Systems for $1.67 billion. This group encompassed Sanders Associates, Fairchild Systems, and Lockheed Martin Space Electronics & Communications.In 2001 Lockheed Martin won the contract to build the F-35 Lightning II. This is the most important fighter aircraft procurement project since the F-16, with an initial order of 3,000 worth $200 billion before export orders.In 2003, Lockheed Martin benefited from a U.S. Air Force decision to punish the Boeing Company for conducting industrial espionage against its rival. The USAF revoked $1 billion worth of contracts from Boeing and awarded them to Lockheed Martin. The company sued Boeing in 1998 for stealing documents related to a military contract.
