Lockheed Martin aerospace and defense products

Lockheed Martin is a global security and aerospace company that emerged from the 1995 merger of Lockheed Corporation and Martin Marietta. The company's roots trace back to the early 20th century in the United States, established by aviation pioneers such as Allan and Malcolm Lockheed and Glenn L. Martin.

Today, the company is the world's largest defense contractor by revenue. While its corporate headquarters are located in Maryland, it maintains a massive manufacturing footprint across the United States and international facilities in countries like the United Kingdom, Canada, and Australia. Lockheed Martin operates four main business segments: Aeronautics, Missiles and Fire Control, Rotary and Mission Systems, and Space. The company remains a publicly traded entity on the New York Stock Exchange, owned primarily by institutional investors.
