Marquardt Corporation

Marquardt Corporation was an American aerospace and defense engineering enterprise founded in 1944 by aeronautical engineer Roy Edward Marquardt. Established initially as Marquardt Aircraft Company in Venice, California, the business concentrated on ramjet propulsion at a time when the technology was being explored for missiles, target drones, and high-speed aircraft. Its early work moved rapidly from laboratory research to flight testing. Marquardt supplied experimental engines to the United States Navy and Army Air Forces, and its propulsion units were tested on aircraft including the P-51 Mustang, Grumman F7F Tigercat, XP-83, F-82 Twin Mustang, and Lockheed P-80 Shooting Star. The company expanded during the late 1940s and 1950s as ramjets became important to American missile and target-drone programs. Marquardt engines supported the Martin Gorgon test program and later became central to the Air Force's CIM-10 BOMARC surface-to-air missile. To meet production requirements, the company established a large manufacturing facility near Ogden, Utah, which began producing BOMARC engines in 1957. Marquardt also developed supersonic ramjets, supported the Lockheed X-7 research vehicle, and participated in advanced propulsion work involving high-speed flight, nuclear ramjets, liquid-air-cycle engines, and related aerospace technologies. Under Marquardt's broader corporate identity, the company diversified beyond ramjets. Acquisitions and internal programs added electronics, solid-fuel rockets, radar and weapons-system simulators, railway communications, railroad grade-crossing equipment, ram-air turbines, thrust reversers, afterburners, and small rocket motors. Its purchase of Cooper Development Corporation brought expertise in sounding rockets and upper-stage propulsion. The acquisition of Associated Missile Products Company created the Pomona Electronics Division, which developed training and simulation equipment for systems such as the GAM-72 Quail decoy missile, GAM-77 Hound Dog missile, Atlas launch systems, air-defense radar, and B-52 navigation and bombardment equipment. Marquardt became particularly important in spacecraft propulsion. In 1962 North American Aviation selected the company to supply reaction-control engines for Apollo spacecraft. By the 1960s and early 1970s, Marquardt was widely associated with small rocket engines and satellite thrusters, and its products were used across a broad range of United States space vehicles and satellites. The company later supplied small and larger thrusters for the Space Shuttle program, including units described as 25-pound and 870-pound thrusters. The corporation also pursued civil and industrial applications. Through Marquardt Industrial Products Company, it licensed and commercialized the Southern Pacific Railroad Grade Crossing Predictor, a system that calculated train approach speed and allowed crossing gates and warning signals to be activated more efficiently than fixed-distance systems. Other diversification efforts included railroad communications, panoramic imaging, television and broadcast technology, security research, medical and life-support studies, computer-related technology, and advanced materials. Marquardt's growth depended heavily on acquisitions and mergers. It purchased or absorbed several aerospace, electronics, rocket, communications, and scientific organizations, including General Applied Science Laboratories and Automation Laboratories. In 1968 it merged with CCI Inc. of Tulsa, Oklahoma, becoming CCI-Marquardt, Inc.; the combined company later reverted to the CCI name. During the 1970s and 1980s, Marquardt-related operations were repeatedly sold, merged, or reorganized. By the 1990s, remaining business units had fragmented among successor companies. Marquardt Manufacturing Inc. eventually entered bankruptcy, while Marquardt Jet Laboratories was sold to Kaiser Aerospace, later became associated with Primex, and ultimately passed into the corporate lineage that became part of Aerojet Rocketdyne. The original Marquardt corporate brand is therefore defunct, although technologies and successor operations continued in aerospace and propulsion markets.

Roy Edward Marquardt founded Marquardt Aircraft Company in November 1944 after working at Northrop on the YB-35 flying-wing bomber. His work on cooling buried engines led him to investigate whether engine heat could be converted into additional thrust through the ramjet principle. The company began in Venice, California, and soon moved to Van Nuys as its engineering and testing activities expanded. Although wind-tunnel work was among its first activities, Marquardt delivered a small experimental ramjet to the Navy within its first year. The Army Air Forces acquired similar engines in 1946 and tested them on P-51 Mustangs, while Navy trials used the F7F Tigercat and later other aircraft. Marquardt also built a pulse-jet helicopter prototype, although it never entered production. In 1947 and 1948, its engines powered Martin Gorgon test vehicles and were adapted for target-drone development. Larger engines were tested on the P-80 Shooting Star, which became the first manned aircraft powered solely by ramjets. Marquardt's transition to supersonic propulsion began in the late 1940s. Engineers developed inlet systems that slowed supersonic airflow to subsonic speeds suitable for combustion. The company's research aircraft and missile programs helped establish its expertise in high-speed propulsion. In the early 1950s, Marquardt worked on projects including the Navy Rigel missile and the Air Force BOMARC anti-aircraft missile. The Lockheed X-7 provided a high-speed test platform, eventually reaching a reported Mach 4.31 and supporting the development of Marquardt engines for BOMARC. Growth required new capital and manufacturing capacity. In 1949, General Tire and Rubber Company acquired a controlling interest, helping Marquardt move from Venice to the former Timm Aircraft facility in Van Nuys. General Tire later sold its interest to Laurance Rockefeller in 1950. Marquardt subsequently developed a large manufacturing site near Ogden, Utah, for BOMARC engines. The facility opened in June 1957 and began deliveries ahead of schedule. A more advanced engine for the IM-99B Super BOMARC followed. The company diversified through acquisitions and research. In 1958 it acquired Associated Missile Products Company, creating the Pomona Electronics Division, which produced radar and weapons-system simulators. It also acquired Cooper Development Corporation, whose work included solid-fuel sounding rockets and upper stages associated with the launch of Explorer I. Marquardt's electronics activities eventually represented a substantial share of company sales. Other research involved ram-air turbines, aircraft afterburners, thrust reversers, nuclear ramjets, liquid-air-cycle engines, security devices, panoramic photography, and transportation systems. In 1960, Marquardt established a Maryland research laboratory known as the Marquardt Special Projects Laboratory. In 1962, its industrial-products operation began commercializing the Grade Crossing Predictor under license from Southern Pacific Railroad. The system used the speed of an approaching train to control crossing warnings and gates, potentially reducing unnecessary delays compared with fixed-distance activation. That same year, North American Aviation selected Marquardt to supply reaction-control engines for Apollo spacecraft. Small rocket engines and spacecraft thrusters became one of the company's defining business areas during the 1960s. Marquardt continued to broaden its organization through acquisitions. Automation Laboratories was purchased in 1964 for its television and broadcast expertise, including work related to missile simulation. In 1965, General Applied Science Laboratories was merged into Marquardt, bringing the company into closer association with the work of aerospace scientists Antonio Ferri and Theodore von Karman. Railroad communications acquisitions followed in 1966, including R. W. Neill Company and related firms. By 1970, Marquardt was best known for small rocket engines and thrusters. Its components were used in many American spacecraft and satellites, and the company later supplied thrusters for the Space Shuttle program. The decline of ramjet-based military programs, however, weakened the original business model. In 1968 Marquardt merged with CCI Inc. and became CCI-Marquardt, Inc.; after several years the name changed back to CCI Inc. During the 1970s and 1980s, Marquardt units were sold, merged, or reorganized. By the 1990s, surviving operations were distributed among entities including Marquardt Manufacturing Inc. and Marquardt Jet Laboratories. The manufacturing remnant entered bankruptcy, while the jet-laboratory business passed through Kaiser Aerospace and Primex before ultimately becoming part of the Aerojet Rocketdyne corporate lineage. The historic Marquardt Corporation no longer operates as an independent company.
