RTX Corporation in the context of "List of conglomerates"

Collins Aerospace is an American aviation and defence technology company, which is one of the world's largest suppliers of the aerospace and defence products. It was formed in 2018 from the merger between Rockwell Collins and UTC Aerospace Systems. Headquartered in Charlotte, North Carolina, it is a subsidiary of RTX Corporation.

Pratt & Whitney is an American aerospace manufacturer with global service operations. It is a subsidiary of RTX Corporation (formerly Raytheon Technologies). Pratt & Whitney's aircraft engines are widely used in both civil aviation (especially airliners) and military aviation. Its headquarters are in East Hartford, Connecticut. The company is the world's second largest commercial aircraft engine manufacturer, with a 35% market share as of 2020. In addition to aircraft engines, Pratt & Whitney manufactures gas turbine engines for industrial use, marine propulsion, and power generation. In 2017, the company reported that it supported more than 11,000 customers in 180 countries around the world.

The BGM-109 Tomahawk Land Attack Missile (TLAM) is an American long-range, all-weather, jet-powered, subsonic cruise missile that is used by the United States Navy, Royal Australian Navy, Royal Netherlands Navy and Royal Navy in ship and submarine-based land-attack operations.

Developed at the Applied Physics Laboratory of Johns Hopkins University under James H. Walker near Laurel, Maryland, the Tomahawk emerged in the 1970s as a modular cruise missile first manufactured by General Dynamics. Early tests of the missile took place between 1983 and 1993, during which time 23 cruise missiles were tested over northern Canada under the "Canada–U.S. Test and Evaluation Program". The goal of the program was to simulate the climate and terrain similar to that of the northern Soviet Union, and to allow the North American Aerospace Defence Command (NORAD) to develop an anti-cruise capability. The Tomahawk aimed to fulfill the need for a medium- to long-range, low-altitude missile with diverse capabilities. Its modular design allows for compatibility with a range of warheads, including high-explosive, submunitions, and bunker-busters. The Tomahawk can use a variety of guidance systems, including GPS, inertial navigation, and terrain contour matching. Over a dozen variants and upgraded versions have been developed since the original design, including air-, sub-, and ground-launched configurations with both conventional and nuclear armaments. The Tomahawk's manufacturing history has seen several transitions. General Dynamics served as the sole supplier in the 1970s. From 1992 until 1994, McDonnell Douglas was the sole supplier of Tomahawks, producing Block II and Block III versions and remanufacturing many Tomahawks to Block III specifications. In 1994, Hughes Aircraft, having purchased General Dynamics' missile division in 1992, outbid McDonnell Douglas to become the sole supplier of Tomahawks. A joint venture between Hughes and Raytheon manufactured the missile from 1995 until Raytheon's acquisition of Hughes in 1997, solidifying their position as the sole supplier. In 2016, the US Department of Defense purchased 149 Tomahawk Block IV missiles for $202.3 million. As of 2024, Raytheon remains the sole manufacturer of non-nuclear, sea-launched Tomahawk variants.

Raytheon Intelligence & Space (RIS) was one of the four business segments of U.S. defense and aerospace conglomerate RTX Corporation. Headquartered in Arlington, Virginia, RIS has a total employment of 39,000 and 2019 sales of US$15 billion. Roy Azevedo is the segment's president.

Raytheon Intelligence & Space is the result of a merger between two former Raytheon Company businesses: Raytheon Intelligence, Information and Services (IIS) and Raytheon Space and Airborne Systems (SAS). The merger was finalized on the day that Raytheon Technologies was formed, on 3 April 2020.

Raytheon is a business unit of RTX Corporation and is a major U.S. defense contractor and industrial corporation with manufacturing concentrations in weapons and military and commercial electronics. Founded in 1922, it merged in 2020 with United Technologies Corporation to form Raytheon Technologies, which changed its name to RTX Corporation in July 2023.

Raytheon was established in 1922, reincorporated in 1928, and adopted the Raytheon Company name in 1959. More than 90% of Raytheon's revenues were obtained from military contracts and, as of 2012, it was the fifth-largest military contractor in the world. As of 2015, it was the third-largest defense contractor in the United States by defense revenue. It was the world's largest producer of guided missiles, and was involved in corporate and special-mission aircraft until early 2007. In 2018, the company had around 67,000 employees worldwide and annual revenues of about US$25.35 billion.

Rockwell Collins, Inc. was a multinational corporation headquartered in Cedar Rapids, Iowa, providing avionics and information technology systems and services to government agencies and aircraft manufacturers. It was formed when the Collins Radio Company, facing financial difficulties, was purchased by Rockwell International in 1973. In 2001, the avionics division of Rockwell International was spun off to form the current Rockwell Collins, Inc., retaining its name.

It was acquired by United Technologies Corporation on November 27, 2018, and since then operates as part of Collins Aerospace, a subsidiary of the RTX Corporation (formerly Raytheon Technologies).
