Original vintage 1963 Martin Marietta advertisement for the company's nuclear power systems - "Martin Marietta is producing small nuclear power systems that provide reliable electric power where it has never been possible before.  One system under development controls the flow of oil from underseas oil wells.  It will sit on the ocean floor and operate unattended for years at a stretch."

The Martin Marietta Corporation was an American company founded in 1961 through the merger of Glenn L. Martin Company and American-Marietta Corporation.  In 1995, it merged with Lockheed Corporation to form Lockheed Martin.
 
Baltimore-based Martin was primarily an aerospace concern with a focus on missiles, namely its Titan program, a family of intercontinental ballistic missiles (ICBM) and medium- and heavy-lift expendable launch vehicles used between 1959 and 2005.  This program was established in 1955 when the company secured a U.S. Air Force contract to build the country's second ICBM. Separately (until 1961, of course), American-Marietta was headquartered in Chicago and produced paints, dyes, metallurgical products, construction materials, and other goods.
 
But in 1963, the company also built the MH-1A, the first floating nuclear power station.  Named Sturgis after General Samuel D. Sturgis III, this pressurized water reactor built in a converted Liberty ship was part of a series of reactors in the US Army Nuclear Power Program, which aimed to develop small nuclear reactors to generate electrical and space-heating energy primarily at remote, relatively inaccessible sites.  After its first criticality in 1967, MH-1A was towed to the Panama Canal Zone that it supplied with 10 MW of electricity. Its dismantling began in 2014 and was completed in 2019.
 
As a fun aside in 1969, the company built the Mark IV monorail (Mk4) monorail train for the Walt Disney World Monorail System, with ten trains built by Martin Marietta at the cost of about $7 million USD each.  These trains were used on the monorail system between 1971 and 1989 before being replaced by the Mark VI monorail, although a few lasted until 1991.
 
But make no mistake, the company’s main business line was Cold War armaments, making some of the first precision-guided weapons, like the AGM-62 WALLEYE and AGM-12 BULLPUP missiles, the former of which was W72 nuclear warhead capable, as well as the solid-fueled MGM-31A PERSHING field artillery theater ballistic missile system – the same missile had its 1980s film debut in John Hughs “Weird Science” (1985), when a PERSHING missile is created from the cover of a January 1983 Time magazine.
 
In 1982, Martin Marietta was subject to a hostile takeover bid by the Bendix Corporation, headed by William Agee.  Bendix bought the majority of Martin Marietta shares and in effect owned the company.  However, Martin Marietta's management used the short time separating ownership and control to sell non-core businesses and launch its own hostile takeover of Bendix (known as the Pac-Man defense).
 
Thomas G. Pownall, CEO of Martin Marietta, was successful and the end of this extraordinarily bitter battle saw Martin Marietta survive; Bendix was bought by Allied Corporation.
 
In July 1993 CEO Norman Augustine participated in what he called the "Last Supper" at the Pentagon, during which then-U.S. Secretary of Defense Les Aspin and Deputy Secretary of Defense William Perry disclosed to a number of prime contractors that, because the Cold War had drawn to a successful conclusion, the defense industry would shrink and the Department of Defense had no need for the plethora of them.  The flurry of mergers in this industry over the next decade can be traced to this event, including this company's merger with Lockheed.
 
The consolidation thus resulted in the "Big Five" military contractors to grow far larger than they would have without consolidation, leading to monopoly and antitrust concerns in the modern day.
