TRW Inc. was an American corporation involved in a variety of businesses, mainly aerospace, electronics, automotive, and credit reporting.[2] It was a pioneer in multiple fields including electronic components, integrated circuits, computers, software and systems engineering. TRW built many spacecraft, including Pioneer 1, Pioneer 10, and several space-based observatories. It was #57 on the 1986 Fortune 500 list,[3] and had 122,258 employees.[1] The company was called Thompson Ramo Wooldridge Inc., after the 1958 merger of the Ramo-Wooldridge Corporation and Thompson Products. This was later shortened to TRW.
The company was founded in 1901 and lasted for just over a century until being acquired by Northrop Grumman in 2002. It spawned a variety of corporations, including Pacific Semiconductors, The Aerospace Corporation, Bunker-Ramo and Experian. Its automotive businesses were sold off by Northrop Grumman as TRW Automotive, which is now part of ZF Friedrichshafen. TRW veterans were instrumental in the founding of corporations like SpaceX.[4] [5]
In 1953, the company was recruited to lead the development of the United States' first ICBM.[6] [7] Starting with the initial design by Convair, the multi-corporate team launched Atlas in 1957.[8] It flew its full range in 1958 and was then adapted to fly the Mercury astronauts into orbit.[8] TRW also led development of the Titan missile,[6] which was later adapted to fly the Gemini missions. The company served the U.S. Air Force as systems engineers on all subsequent ICBM development efforts[9] but TRW never produced any missile hardware because of the conflict of interest.[10] In 1960, Congress spurred the formation of the non-profit Aerospace Corporation to provide systems engineering support to the U.S. government[6] but TRW continued to guide the ICBM efforts.
TRW originated in 1901 with the Cleveland Cap Screw Company, founded by David Kurtz and four other Cleveland residents.[11] Their initial products were bolts with heads electrically welded to the shafts. In 1904, a welder named Charles E. Thompson adapted their process to making automobile engine valves [11] and by 1915, the company was the largest valve producer in the United States.[12] Charles Thompson was named general manager of the company, which became Thompson Products in 1926.[13] Their experimental hollow sodium-cooled valves aided Charles Lindbergh's solo flight across the Atlantic.[12]
In 1937, Thompson Motor Products bought J.A. Drake and Sons (JADSON). The company made high-performance valves that were used in many racing engines of the day, including the Miller Offy. Dale Drake (son of J.A. Drake) bought the Offy engine design with his partner Louis Meyer in 1946 and won the Indianapolis 500 twenty-seven times, more than any other engine design.[14]
During the period leading up to World War II, through the end of the Korean war, Thompson Products was a key manufacturer of component parts for aircraft engines, including cylinder valves. The TAPCO plant, owned by the U.S. government but operated by Thompson Products, extended for almost a mile along Cleveland's Euclid Avenue. It employed over 16,000 workers at the peak of WW II production. As jet aircraft replaced piston-engined aircraft, Thompson Products became a major manufacturer of turbine blades for jet engines.
In 1950, Simon Ramo and Dean Wooldridge while working for Hughes Aircraft, led the development of the Falcon radar-guided missile, among other projects. They grew frustrated with Howard Hughes' management, and formed the Ramo-Wooldridge Corporation in September 1953, with the financial support of Thompson Products. The detonation of a thermonuclear bomb by the Soviet Union spurred Trevor Gardner to form the Teapot Committee in October 1953. Chaired by John von Neumann, its purpose was to study the development of ballistic missiles, including ICBMs. Ramo and Wooldridge were committee members, and Ramo-Wooldridge Corp. became the lead contractor of the resulting ICBM development effort, reporting to the United States Air Force.
With continued backing from Thompson Products, Ramo-Wooldridge diversified into computers and electronic components, founding Pacific Semiconductors in 1954.[15] [16] They also produced scientific spacecraft such as Pioneer 1. Thompson Products and Ramo-Wooldridge merged in October 1958 to form Thompson Ramo Wooldridge Inc., unofficially known as "TRW".[13] In February 1959, Jimmy Doolittle became chairman of the board of Space Technology Laboratories (STL), the division which continued to support the Air Force ICBM efforts.[13]
Other aerospace companies believed TRW's Air Force advisory role granted it unfair access to their technologies [15] and in September 1959, Congress issued a report recommending that STL be converted to a non-profit organization. With nearly half of STL's employees,[13] The Aerospace Corporation was formed in June 1960. It headed the Atlas conversion for Mercury, Titan conversion for Gemini, and provided ongoing systems engineering support for the government. The Air Force continued its ICBM work with TRW.[2]
Dean Wooldridge retired in January 1962 [13] to become a professor at California Institute of Technology (Caltech).[2] Simon Ramo became president of the Bunker-Ramo Corporation in January 1964, jointly owned by TRW and Martin Marietta for the production of computers and monitors. Thompson Ramo Wooldridge officially became TRW Inc. in July 1965.[13] Free of anti-competitive restrictions short of ICBM hardware, STL was renamed TRW Systems Group that same month.[13] In 1968, the company entered the credit reporting industry by purchasing Credit Data Corporation and renaming it TRW Information Systems and Services Inc. The Credit Data group was formed in 1970 [13] to compete with Dun & Bradstreet,[2] from the combination of TRWISS and ESL Incorporated[13] to specialize in technical strategic reconnaissance. TRW Information Systems and Services Division (Credit Data) was spun off in 1996 to form Experian.[17] TRW acquired LucasVarity in 1999, then selling Lucas Diesel Systems to Delphi Automotive and Lucas Aerospace (then called TRW Aeronautical Systems) to Goodrich Corporation.[18]
The company was 57th [3] on the Fortune 500 list of highest revenue American companies in 1986 and had 122,258 employees in 2000.[1] It operated in 25 countries.[2]
On 3 February 1986, the TRW plant in Harrisburg, Pennsylvania, burned to the ground in an eight-alarm fire.[19] The damage was estimated to be greater than US$10 million and was the most serious fire to date in the area.
In February 2002, Northrop Grumman launched a US$5.9 billion hostile bid for TRW. Northrop Grumman, BAE Systems, and General Dynamics contended for the company with Northrop's increased bid of US$7.8 billion ultimately being accepted on July 1, 2002. Soon afterward, the automotive assets of LucasVarity and TRW's own automotive group were sold to The Blackstone Group as TRW Automotive.[20]
A portion of TRW's Lyndhurst campus was developed as Legacy Village. The headquarters building became home to the Cleveland Clinic Wellness Institute.[21] The TRW headquarters building was demolished in 2023.[22] [23]
Bill Gates, the founder of Microsoft, says that he got "his first big break" at age fifteen, debugging energy-grid control software for TRW. "It was kind of scary", Gates said, realizing the things the program was going to help operate. "This thing needs to work".[24]
TRW Inc. was active in the development of missile systems and spacecraft, notably, the early development of the U.S. ICBM program under the leadership of the Teapot Committee led by John von Neumann. TRW pioneered systems engineering, creating the ubiquitous N2 chart and the modern functional flow block diagram. It served as the primary source of systems engineering for the United States Air Force ballistic missile programs.[25]
Space Technology Laboratories (STL), then a division of Ramo-Wooldridge Corp., designed and produced the identical payloads for Pioneer 0, Pioneer 1 and Pioneer 2. These were intended to orbit and photograph the Moon, but launch vehicle problems prevented this. NASA launched Pioneer 1 as its first spacecraft on 11 October 1958.[26] It set a distance record from Earth, and provided data on the extent of Earth's radiation belts.
Pioneer 10 and 11 were nearly identical spacecraft, designed and fabricated by TRW Systems Group.[27] They were optimized for ruggedness since they were the first man-made objects to pass through the asteroid belt and Jupiter's radiation belt. Simplicity, redundancy, and use of proven components were essential.[28] As NASA's first all-atomic powered spacecraft,[29] these used plutonium-238 units developed by Teledyne Isotopes.[30] Pioneer 10 carried eleven instruments and Pioneer 11 carried twelve for investigating Jupiter and Saturn, respectively.[31] Data was transmitted back to Earth at 8 watts, 128 bytes/s at Jupiter,[32] and 1 byte/s from further out. Pioneer 10 was the first man-made object to pass the planetary orbits and its last telemetry was received in 2002, thirty years after launch.[33]
TRW Systems Group designed and built the instrument package which performed the Martian biological experiments,[34] searching for life aboard the two Viking Landers launched in 1975. The system performed four experiments on Martian soil using a gas chromatograph-mass spectrometer (GC-MS) and a combined biological instrument.
TRW designed and built the following space observatories:
The teams developing the following observatories continued their work as part of Northrop Grumman Aerospace Systems:
TRW Systems Group designed and manufactured the Vela series of nuclear detection satellites which monitored the 1963 establishment of the nuclear Partial Test Ban Treaty.[36] Subsequently, they produced the Advanced Vela series, first launched in 1967, which could detect nuclear air bursts using instruments actually called bhangmeters. It had the first dual-spin attitude control system with the total system momentum controlled to zero.[37] The Vela and Advanced Vela satellites were the first to alert astronomers to the presence of gamma-ray bursts. They also reported a mysterious apparent nuclear test now called the Vela incident.
First launched in 1970, the company built all twenty-three reconnaissance satellites in the Defense Support Program (DSP), which are the principal components of the Satellite Early Warning System currently used by the United States. These are operated by the Air Force Space Command, and they detect missile or spacecraft launches and nuclear explosions using sensors that detect the infrared emissions from these intense sources of heat. During Desert Storm, for example, DSP satellites were able to detect the launches of Iraqi Scud missiles and provide timely warnings to civilians and military forces in Israel and Saudi Arabia.[38]
The initial seven Tracking and Data Relay Satellite System (TDRSS) were built by TRW to improve communication coverage for the Space Shuttle, International Space Station (ISS), and U.S. military satellites. When first launched in 1983, the TDRS satellites were the largest, most sophisticated communications satellites built at the time.[39] The seventh vehicle in the series was ordered as a replacement when TDRS-B was lost in the Challenger accident.
Launched in 2002, TRW produced the Aqua spacecraft based on their modular standardized satellite bus.[40] A joint project of the U.S. Global Change Research Program (NASA), Japan Aerospace Exploration Agency (JAXA), and National Institute for Space Research (INPE), Brazil, Aqua delivers 750 Gigabytes per day detailing the Earth's water cycle in the oceans, lakes, atmosphere, polar ice caps, and vegetation.
TRW designed and built the descent engine or (LMDE) for the Apollo lunar lander. Due to the need for a soft landing on the Moon, it was the first throttleable engine for crewed space flight. This, and the requirements for high thrust, low weight, and crushability (in case of landing on a large rock),[16] earned surprising praise from NASA's history pages, considering the complexity of the lunar missions: "The lunar module descent engine probably was the biggest challenge and the most outstanding technical development of Apollo".[41] This engine was used on Apollo 13 to achieve free return trajectory and make a minor course correction after damage to the Service Module.
After the Apollo program Moon landings, the LMDE was further developed into the TRW TR-201 engine. This engine was used in the second stage Delta-P of the Delta launch vehicle for 77 launches between 1972–1988.
At the turn of 1964-65, the United States started the ambitious Bushmaster program to create small-caliber assault guns for arming promising infantry fighting vehicles (IFVs) of the American Army. The result of this program was the creation of a whole series of automatic cannons with an external automatic drive in caliber from 25 to 40 mm, which received their own general name Bushmaster.
At the early stage of American research, TRW was one of the companies involved in the development of automatic guns of the Bushmaster program, where, under the leadership of engineer Eugene Stoner, the author of the famous M16 rifle, a 25 mm automatic cannon was developed under the internal designation TRW model 6425, an ordinary system with automatic gas venting and locking the barrel with a rotary bolt is enough.[42]
The TRW-6425 design was later bought from Oerlikon-Bührle, it was improved and manufactured as the Oerlikon KBA 25 mm.[43] [44]
The Ramo-Wooldridge Corp formed Pacific Semiconductors in June 1954, under the leadership of Harper North who had been head of electronics R+D at Hughes Aircraft Company. The funding for this endeavor from Thompson Products was about ten times their initial investment in Ramo-Wooldridge.[15] [16] The original goal was to produce the recently invented transistor for commercial sales.
In 1957, Howard Sachar and Sanford "Sandy" Barnes invented the Varicap electronic component (also known as the varactor diode) at Pacific Semiconductors.[45] This device reduced the physical size of radio tuners and eliminated the need for moving mechanical parts. This simplified the implementation of remote control TV tuners. Sachar and Barnes were awarded an Emmy in 2007.[46]
The company manufactured the RW-300 for sales in 1959, one of the first "all-transistor" computers[15] with a power supply that used vacuum tubes. The computer was targeted at industrial control applications, with 1024 analog inputs multiplexed to a 1.9K sample/s 10-bit analog-to-digital converter which was transparent to the programmer. It weighed about .[47] [48] The real-time operating system was written by John Neblett, and was the intellectual precursor of the RSX-11 operating system for the PDP-11.[49]
The TRW-130 computer was introduced in 1961,[50] [51] and designated the AN/UYK-1 by the U.S. Navy as part of its pre-GPS TRANSIT (NAVSAT) satellite-based location system. It used Doppler shifts to compute a location in about 15 minutes, and had rounded corners to allow installation in submarines.
The Transistor Transistor Logic (TTL) logic gate, which was the electronics industry standard for two decades, was invented by TRW's James L. Buie in 1961.
In 1965, engineers Don Nelson and Dick Pick at TRW developed the Generalized Information Retrieval Language and System, for use by the U.S. Army to control the inventory of Cheyenne helicopter parts. This developed into the Pick Database Management System which is still in use as of 2016.[52]
TRW LSI Products, Inc. was a wholly owned subsidiary formed to commercialize the integrated circuit technology the company had developed in support of its aerospace business. They produced some of the first commercially available digital signal processing ICs including the TDC1008 multiplier-accumulator.[53] They also made the first 8-bit flash ADC IC, the TDC1007,[54] resulting in an Emmy Award for analog/digital video conversion technology.[55] TRW also pioneered gallium arsenide (GaAs) chip applications for local multipoint distribution service (LMDS) systems, radios, and satellite communications.[56]
Bel Canto Stereophonic Recordings, a TRW subsidiary, was a record label active from the mid-1950s to the early 1960s.[57]
Christopher John Boyce was a TRW employee convicted of selling security secrets to the Soviet Union via the Soviet embassy in Mexico City in the mid-1970s. Boyce and his accomplice, Andrew Daulton Lee, were the subjects of the best-selling 1979 Robert Lindsey book The Falcon and the Snowman, and the 1985 film of the same title.
Representatives from Space Technology Laboratories (STL) present their ICBM expertise to Don and Pete in Mad Men season 2 episode "The Jet Set".[58]
The season 1 episode "Operation -- Annihilate!" (13 April 1967) was filmed on the then-TRW campus (now Northrop Grumman's Space Park) in Redondo Beach, California. The two sets of stairs shown are those leading to the cafeteria of Building S.[59] William Shatner had previously filmed at the TRW campus for the Outer Limits episode "Cold Hands, Warm Heart". In the episode, he plays an astronaut for "Project Vulcan". The 1967 sci-fi film Countdown, also filmed at the TRW Space Park.
The TRW building is supposedly one of the credit company buildings demolished in the 1999 film Fight Club. This is because at the time the book was written, TRW was in the business of credit reporting. However, there is no TRW building in Delaware, where the demolition purportedly happens.[60]
TRW equipment/boxes can be seen stored and being unloaded in the film Close Encounters of the Third Kind during scenes filmed at Devils Tower.
In the 1960s and 1970s, TRW stored trichloroethylene (TCE), a critical chemical for cooling and degreasing computer chips, in tanks deep underground in Sunnyvale, California for later use.[70] TCE is also found in household cleaners.[71] As a result of pipe and tank degradation, the tanks leaked into the ground, resulting in contaminated soil and groundwater.[72] TCE was later determined to be toxic to humans at high concentrations. In 2013, The Atlantic referred to the site as a "paved-over environmental disaster zone".[73]
In the 1980s, the US introduced the federal Superfund program to clean up the country's toxic waste sites.[74] The site TRW (now Northrop Grumman) is responsible for is called the 'TRW Microwave site
In the 2000s, a bioremediation method developed by Stanford University using bacteria in molasses to naturally breakdown the TCE into harmless sub-compounds was implemented.[82] [83] Other measures included engineering vapor pathways to avoid direct human contact by releasing it into the air.[84] Jared Blumenfeld, the former EPA director, said that TCE released in the air after the cleanup efforts reduces the concentrations to levels that eliminate health risks.[85] Blumenfeld said that airborne TCE is not ideal, but the cleanup has reduced the toxins by 90%, according to Max Shahbacian, the project's lead at California State Water Resources Control Board before it was transferred to the EPA, and geologist Michael Calhoun.[86] [87]
In 2014 and 2015, a newly required vapor intrusion test of the surrounding residential area, including homes, apartment buildings, and four schools, showed unacceptable levels of TCE.[88] [89] A 2011 study had revealed TCE caused birth defects and cancer by all pathways of exposure.[90] [91] [92] In 2014, the region's congressional representative Anna Eshoo expressed concerns that the EPA had not been properly monitoring the site and notififying residents of a possible health issue.[93] The EPA litigated with the responsible parties in order update its notification and testing measures to warn residents about possible exposure as early as possible and keeping people away from any unsafe areas.[94]
, the site is owned by GI Partners, an investment company, and has been leased by Apple Inc. since 2015 for research and development .[95] [96] [97] The octagonal glass building was renovated in 2014 and made available for occupancy in 2015. The safety of the site was verified by the EPA.[98] In 2016, the Donald Trump administration cut funding the Superfund program by $330 million and EPA funding by more than 30%, resulting in a significant reduction in enforcement and testing.[99] [100] [101] During his presidency, the EPA increased its use of consent decrees, or administrative settlements, to ensure progress continued under the budget cuts, forcing responsible parties to pay for the cleanup. Scott Pruitt, Trump's head of the EPA threatened to cut budgets again for the enforcement.[102] [103] [104] In 2019, the EPA and Philips Semiconductors agreed to a consent decree, with Northrop Grumman as a signatory, to fund the remaining cleanup and monitoring of the site, along with two nearby sites collectively known as the "Triple Site".[105] [106]
In March 2021, Ashley Gjøvik, a former Apple program manager, publicized concerns that the site had not been properly tested since 2015 after receiving an email from Apple notifying employees of forthcoming vapor intrusion testing.[107] [108] An EPA study in 2019 had confirmed the previous remedies effective,[109] but Gjøvik told TechCrunch cracks in the floor were exposing employees to carcinogenic fumes.[110] She filed a whistleblower complaint with the Occupational Safety and Health Administration against Apple,[111] which was investigated and dismissed.[112] [113] A site evaluation by the EPA done in August 2021 found that the likelihood for vapor intrusion was low and not expected.[114] Based on field testing done between April 24, 2023 and May 5, 2023, the EPA concluded that vapor intrusion was being prevented.[115]
