RTX Corporation, called Raytheon Technologies until 2023, is one of the largest aerospace and defense companies in the world by sales. Collins Aerospace supplies aircraft systems, Pratt & Whitney designs and services jet engines, and Raytheon builds missiles, radars and defense electronics. The company is publicly traded on the NYSE under the ticker RTX and is led by Chairman and CEO Christopher Calio. The company is headquartered in Arlington, Virginia.
RTX earns money in three ways. First, it sells original equipment: Pratt & Whitney GTF and F135 engines, and Collins avionics, actuation, landing gear, power systems and cabin interiors installed on Airbus, Boeing, Embraer and military aircraft. Second, it earns recurring aftermarket revenue from spare parts, overhauls and long-term engine service agreements over aircraft lives of 25 years or more; commercial aftermarket is among its highest-margin work. Third, Raytheon sells missiles, radars, sensors and air defense systems such as Patriot, AMRAAM, Tomahawk, Standard Missile and SPY-6 to the U.S. government and allied nations, through both cost-plus and fixed-price contracts. In 2025, 52% of sales were defense and 48% commercial, and 53% of sales came from the United States.
