## About

Raytheon Company was founded in Cambridge, Massachusetts in 1922 by Laurence K. Marshall, Vannevar Bush, and Charles G. Smith. A century later, its legacy lives on within RTX, a Massachusetts-based aerospace and defense conglomerate. The 2020 all-stock merger merged Raytheon's missile and sensor business with United Technologies' aerospace divisions (Pratt & Whitney, Collins Aerospace). RTX develops guided missiles (Patriot, Tomahawk), radar systems, and jet engines for the US Department of Defense and allied nations. It also supplies avionics and cabin interiors to commercial aviation. The company reports four segments: Collins Aerospace, Pratt & Whitney, Raytheon Intelligence & Space, and Raytheon Missiles & Defense. Geographically, over half of revenue comes from the US government, with major sales to Europe, the Middle East, and Asia-Pacific. The firm employs roughly 182,000 people globally, down from 195,000 post-merger. RTX maintains major facilities in Arizona, Indiana, Connecticut, and Massachusetts. In August 2024, RTX announced the sale of its cybersecurity business, Nightwing, to private equity firm AE Industrial Partners for $1.3B. RTX is a public company (NYSE: RTX), not a family office. Its board is chaired by Gregory J. Hayes, former CEO of both United Technologies and the combined RTX. Succession planning placed Calio, a 28-year company veteran, as CEO in 2024.
