The Lockheed Martin Corporation is an American defense and aerospace manufacturer with worldwide interests. It was formed by the merger of Lockheed Corporation with Martin Marietta in March 1995. It is headquartered in North Bethesda, Maryland. As of January 2022, Lockheed Martin employs approximately 115,000 employees worldwide, including about 60,000 engineers and scientists.^[3] Reports from 2024 estimate that Lockheed Martin Corporation (LMT) holds a market cap of around $139.7 billion.^[4]

Lockheed Martin is one of the largest companies in the aerospace, military support, security, and technologies industry. It was the world's largest defense contractor by revenue for fiscal year 2014.^[5] In 2013, 78% of Lockheed Martin's revenues came from military sales;^[6] it topped the list of US federal government contractors and received nearly 10% of the funds paid out by the Pentagon.^[7] In 2009, US government contracts accounted for $38.4 billion (85%), foreign government contracts for $5.8 billion (13%), and commercial and other contracts for $900 million (2%).^[8] Half of the corporation's annual sales are to the U.S. Department of Defense. Lockheed Martin is also a contractor for the U.S. Department of Energy and the National Aeronautics and Space Administration (NASA).^[9]

Lockheed Martin operates in four business segments: Aeronautics, Missiles and Fire Control (MFC), Rotary and Mission Systems (RMS), and Space.^[10] The company has received the Collier Trophy six times, including in 2001 for being part of developing the X-35/F-35B LiftFan Propulsion System^[11][12][13] and most recently in 2018 for the Automatic Ground Collision Avoidance System (Auto-GCAS). Lockheed Martin is currently developing the F-35 Lightning II and leads the international supply chain, leads the team for the development and implementation of technology solutions for the new USAF Space Fence (AFSSS replacement),^[14] and is the primary contractor for the development of the Orion command module.^[15] The company also invests in healthcare systems, renewable energy systems, intelligent energy distribution, and compact nuclear fusion.^[16]

Merger talks between Lockheed Corporation and Martin Marietta began in March 1994, with the companies announcing their $10 billion planned merger on August 30, 1994.^[17][18] The headquarters for the combined companies would be at Martin Marietta headquarters in North Bethesda, Maryland.^[19] The deal was finalized on March 15, 1995, when the two companies' shareholders approved the merger.^[20] The segments of the two companies not retained by the new company formed the basis for L-3 Communications, a mid-size defense contractor in its own right. Lockheed Martin also later spun off the materials company Martin Marietta Materials.^{[citation needed]}

The company's executives received large bonuses directly from the government as a result of the merger. Norman R. Augustine, who was at the time CEO of Martin Marietta, received an $8.2 million bonus.^[21]

Both companies contributed important products to the new portfolio.^{[citation needed]} Lockheed products included the Trident missile, P-3 Orion maritime patrol aircraft, U-2 and SR-71 Blackbird reconnaissance airplanes, F-117 Nighthawk, F-16 Fighting Falcon, 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.^{[citation needed]}

On April 22, 1996, Lockheed Martin completed the acquisition of Loral Corporation's defense electronics and system integration businesses for $9.1 billion, the deal having been announced in January. The remainder of Loral became Loral Space & Communications.^[22] Lockheed Martin abandoned plans for an $8.3 billion merger with Northrop Grumman on July 16, 1998, 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.^[23]

For the Mars Climate Orbiter, Lockheed Martin incorrectly provided NASA with software using measurements in US Customary force units when metric units were expected; this resulted in the loss of the Orbiter at a cost of $125 million.^[24][25] The development of the spacecraft cost $193 million.^[26][27]

In addition to their military products, in the 1990s Lockheed Martin developed the texture mapping chip for the Sega Model 2 arcade system board and the entire graphics system for the Sega Model 3, which were used to power some of the most popular arcade games of the time.^[28]

In May 2001, Lockheed Martin sold Lockheed Martin Control Systems to BAE Systems.^[29] On November 27, 2000, Lockheed completed the sale of its Aerospace Electronic Systems business to BAE Systems for $1.67 billion, a deal announced in July 2000. This group encompassed Sanders Associates, Fairchild Systems, and Lockheed Martin Space Electronics & Communications.^[30][31] In 2001, Lockheed Martin won the contract to build the F-35 Lightning II; this was the largest fighter aircraft procurement project since the F-16, with an initial order of 3,000 aircraft. In 2001, Lockheed Martin settled a nine–year investigation conducted by NASA's Office of Inspector General with the assistance of the Defense Contract Audit Agency. The company paid the United States government $7.1 million based on allegations that its predecessor, Lockheed Engineering Science Corporation, submitted false lease costs claims to NASA.^[32]

Lockheed Martin is listed as the largest U.S. government contractor and ranks first for the number of incidents, and fifth for the size of settlements on the 'contractor misconduct' database maintained by the Project on Government Oversight, a Washington, D.C.–based watchdog group. Since 1995, the company has agreed to pay $676.8 million to settle 88 instances of misconduct.^[141]

In 2013, Lt. Gen. Christopher Bogdan criticized the company's F-35 fighter program. The general said: "I want them both to start behaving like they want to be around for 40 years ... I want them to take on some of the risk of this program. I want them to invest in cost reductions. I want them to do the things that will build a better relationship. I'm not getting all that love yet."^[142] The criticism came in the wake of previous criticism from former Defense Secretary Robert Gates regarding the same program.^[143]

According to the magazine Politico, Lockheed Martin has "a political network that is already the envy of its competitors", and its contracts enjoy wide bipartisan support in the U.S. Congress thanks to it having "perfected the strategy of spreading jobs on weapons programs in key states and congressional districts".^[144] The company's 2022 lobbying expenditure is $13.6 million (2009 total: $13.7 million).^[145][146]

Through its political action committee (PAC), the company provides low levels of financial support to candidates who advocate national defense and relevant business issues.^[147] It was the largest contributor to the House Armed Services Committee chairman, Republican Buck McKeon of California with over $50,000 donated in the election cycle as of January 2011. It also was the top donor to Sen. Daniel Inouye (D-HI), the chair of the Senate Appropriations Committee before his death in 2012.^[125]

Lockheed Martin Employees Political Action Committee is one of the 50 largest in the country, according to FEC data. With contributions from 3,000 employees, it donates $500,000 a year to about 260 House and Senate candidates.^{[148][needs update]}

Senior management consists of the CEO, CFO, and Executive Vice Presidents (EVPs) of four business areas.^[149][150] The EVPs are responsible for managing major programs.^{[citation needed]}

On March 16, 2020, Lockheed announced that CEO Marillyn Hewson would become executive chair and be succeeded as CEO by James Taiclet on June 15; Taiclet was at the time the head of American Tower, and had previously been the president of Honeywell Aerospace and before that a VP at United Technologies. Lockheed also announced that it would create the chief operating officer role, to which current EVP Frank A. St John would be promoted.^[151]

Employees in each program are organized into four tiers: Tier1 –Program Manager/VP, Tier2-Functional Teams (Finance, Chief Engineer, Quality, Operations, etc.), Tier3-Integrated Product Teams (IPTs) (Weapon System Development, Weapon System Integration, etc.), and Tier4-detailed product development. Floor or touch workers belong to component assembly teams.^[152] Lockheed Martin manages and maintains its relationship with these touch workers through its supervisors and unions.^[153]

Lockheed Martin manages employees through its Full Spectrum Leadership and LM21 programs.^[154] The LM21 program relies on Six Sigma principles, which are techniques to improve efficiency. Senior management constructs leadership councils and assigns managers to facilitate Kaizen events, which target specific processes for improvement. A manager facilitates teams and processes stakeholders and suppliers to streamline process implementation.^{[155][156][152]}

Tier2 Functional Leads and Tier3 IPT Leads report to Tier1. IPT leads are responsible for entire systems or products defined by the contract's Statement of Work.^[152]

To control quality, Lockheed Martin trains and builds IPT teams.^[152] and ensures that work is executed correctly through a Technical Performance Measure (TPM) system which emphasizes its Lean and 6 Sigma processes. Middle management uses commitment mechanisms that parallel high commitment and human relations theory.^[157]

Floor employees assemble aircraft using Flow-to-takt lean manufacturing process^[158] which uses properties from both division of labor and scientific management. By separating tasks based on parts, Lockheed Martin utilizes the division of labor theory,^[159] specialization on a specific area creates efficiency.^{[citation needed]}

The "Double Helix methodology" is a systems development methodology used by Lockheed Martin. It combines experimentation, technology, and a warfighter's concept of operations to create new tactics and weapons.^[160]
