UTX

Rtx Corporation

An aerospace and defense giant that builds jet engines, aircraft cabins, and missile-defense systems under three famous names: Pratt & Whitney, Collins Aerospace, and Raytheon. Pratt & Whitney's GTF engines power thousands of airliners and its F135 engine drives the F-35 fighter, while Raytheon's Patriot, AMRAAM, and SM-3 systems protect militaries around the world. The company came together in 2020 when Raytheon merged with United Technologies' aerospace businesses, taking the name RTX from the two.
