Lockheed Martin Corporation (LMT)

Overview

Lockheed Martin is the world's largest defense contractor, formed in 1995 through the merger of Lockheed Corporation and Martin Marietta and tracing its roots back to 1912. Headquartered in North Bethesda (Bethesda), Maryland, the company designs, develops, manufactures, integrates, and sustains advanced technology systems for defense, aerospace, and space customers around the world. Lockheed Martin generates roughly $71-77 billion in annual/trailing-twelve-month revenue, employs about 123,000 people, and sits in the Industrials sector under Aerospace & Defense. It has been the top-ranked contractor to the U.S. federal government by contract dollars since at least 2008, with the large majority of revenue coming from U.S. government customers, primarily the Department of Defense.

What They Do & How They Make Money

Lockheed Martin earns almost all of its revenue from long-cycle government contracts to design, build, upgrade, and sustain military aircraft, missiles, space systems, and related technology — overwhelmingly for the U.S. government (roughly 65-73% of revenue from the U.S. federal government, split between the Department of Defense and other agencies like NASA), with the remainder from foreign military sales and direct commercial sales to allied governments. Revenue comes through several contract types: cost-plus contracts (the government reimburses costs plus a fee, common on R&D-heavy, high-risk programs), fixed-price contracts (Lockheed bears more cost risk but can earn higher margin if it controls costs, common on mature production programs), and long-term sustainment/services contracts that provide recurring revenue over a platform's decades-long service life — sustainment and support work on fielded platforms like the F-35 and legacy F-16 fleets is a large and growing, relatively stable revenue stream distinct from new-unit production. The single largest program is the F-35 Lightning II stealth fighter, which alone represents roughly a quarter of total company revenue across development, production for the U.S. and partner nations, and decades of expected sustainment work — making Lockheed's fortunes heavily tied to F-35 production rates, allied nation orders, and the jet's lifecycle sustainment contracts (which have themselves been contentious over cost and data-rights disputes with the Pentagon).

Business Segments

Lockheed Martin reports four business segments:

Aeronautics (roughly 40% of revenue, the largest segment) — Research, design, development, and production of military aircraft, including the F-35 Lightning II (the flagship program), F-16 Fighting Falcon, F-22 Raptor, and C-130 Hercules airlifter, plus advanced development programs (Skunk Works).
Missiles and Fire Control (MFC) (roughly 17% of revenue) — Air and missile defense systems (THAAD, PAC-3), tactical missiles, precision-strike weapons, and fire-control/targeting systems for the U.S. and allied militaries.
Rotary and Mission Systems (RMS) (roughly 24% of revenue) — Helicopters (Sikorsky, including Black Hawk and CH-53K), naval combat systems (Aegis Combat System), littoral combat ships, radar, and mission systems integration.
Space (roughly 19% of revenue) — Military and commercial satellites, missile defense systems, and space exploration hardware including the Orion crew capsule built for NASA's Artemis program, plus classified national-security space programs.

Aeronautics is consistently the largest revenue contributor given the scale of F-35 production and sustainment, with Rotary and Mission Systems second, and Space and Missiles and Fire Control roughly comparable in size, though relative segment ordering shifts modestly year to year with program timing.

Competitors

RTX Corporation (formerly Raytheon Technologies) — Competes across missiles, missile defense, and avionics; the largest U.S. defense competitor by market capitalization.
The Boeing Company — Competes in military aircraft (F/A-18, F-15EX), space systems, and has historically bid against Lockheed on major aircraft competitions (e.g., beat Lockheed on the Air Force tanker and maritime patrol competitions in some cases, lost the Joint Strike Fighter competition to Lockheed in 2001).
Northrop Grumman — Competes in stealth aircraft (B-21 bomber), space systems, and unmanned systems; also a subcontractor/partner to Lockheed on some programs (including F-35).
General Dynamics — Competes in combat vehicles, submarines, and information systems; historically related to Lockheed through the 1993 sale of General Dynamics' Fort Worth (F-16) division to Lockheed.
L3Harris Technologies — A fast-growing competitor in electronics, sensors, and space, and increasingly a prime contractor after its Aerojet Rocketdyne acquisition.
BAE Systems (UK) — A partner on the F-35 program but also a direct competitor internationally in combat vehicles, naval systems, and electronics.

Competitive Position

Lockheed Martin's competitive moat comes from deep incumbency on programs with multi-decade lifecycles: once a platform like the F-35 is selected and enters production, switching costs for the government are enormous (retraining, logistics, spare parts, sustainment infrastructure), and Lockheed captures recurring, high-margin sustainment revenue for as long as the fleet flies — often 30-plus years. Its scale, security clearances, specialized engineering workforce, and program-management track record on classified and highly complex systems create high barriers to entry that few companies beyond the "big five" U.S. primes (Lockheed, RTX, Boeing, Northrop, General Dynamics) can clear. Its position as the single largest defense contractor also gives it disproportionate influence in shaping requirements and lobbying for program funding, and geographic diversification through F-35 sales to NATO and allied nations (partner countries co-invest in production and buy sustainment services) extends its revenue base and political support beyond the U.S. budget cycle alone.

Key risks include concentration risk in a single program (the F-35 represents about a quarter of revenue, so any production slowdown, allied order cancellation, or major cost/schedule/technical setback disproportionately hurts results — the program has faced hundreds of software deficiencies and cost overruns over its history); dependence on U.S. defense budget levels and the political/appropriations cycle, including exposure to continuing resolutions or budget caps that delay orders; fixed-price contract risk on newer or technically challenging programs, where cost overruns are borne by Lockheed rather than the government; geopolitical risk, since foreign military sales are subject to U.S. export approval and shifting alliance politics; and historical regulatory/compliance exposure, including hundreds of millions of dollars in contractor-misconduct settlements over the decades. Supply chain and workforce constraints (skilled engineering and manufacturing labor, and specialized subcontractor capacity) have also periodically limited how fast Lockheed can ramp production to meet demand.
