Thales S.A.

Thales S.A., trading as Thales Group (French pronunciation: [talɛs]), is a French multinational aerospace and defence corporation specialising in electronics. It designs, develops and manufactures a wide variety of aerospace and military systems, devices and equipment but also operates in the cybersecurity and formerly civil ground transportation sectors. The company is headquartered in Paris' business district, La Défense, and its stock is listed on Euronext Paris.

The company was originally founded as Thomson-CSF in 1968. Following its privatisation, heavy restructuring, and reorganisation around three business areas (defence, aerospace and information technology), the firm was rebranded Thales Group in 2000, reportedly due to the company's desire to simplify and improve its brand. Throughout the 2000s and 2010s, Thales Group completed various acquisitions that have expanded its presence in the defence, ground transportation, and IT sectors.

Thales is partially owned by the French state and operates in more than 68 countries. In 2025, the company generated €22.22 billion in revenue and was the 10th largest defence contractor in the world, with 72 percent of its total revenue generated from its military activities.
