Rocket Development and Test Facility. Neosho, Missouri A rocket engine manufacturing plant was operated by Rocketdyne over a twelve-year period at Neosho, Missouri. The plant was constructed by the U.S. Air Force within a 2,000-acre portion of Fort Crowder, a decommissioned World War II training base. The Rocketdyne division of North American Aviation operated the site, employing approximately 1,250 workers beginning in 1956. The plant primarily produced the MA-5 booster, sustainer and vernier rocket engines, H-1 engines and components for the F-1 and J-2 rocket engines. The P4-1 (a.k.a. LR64) engine was also manufactured for the AQM-37A target drone. The engines and components were evaluated at an on-site test area located approximately one mile from the plant. Rocketdyne closed the plant in 1968. The plant has been used by several different companies for the refurbishment of jet aircraft engines. The citizens of Neosho have placed a commemorative monument dedicated to the men and women of Rocketdyne Neosho "whose tireless efforts and relentless pursuit of quality resulted in the world's finest liquid rocket engines." Nevada Field Laboratory Rocketdyne established and operated a 120,000 acre rocket engine test and development facility nearby Reno, Nevada from 1962 until 1970. The Nevada Field Laboratory had three active open-air test facilities and two administrative areas. The test facilities were used for the Gemini and Apollo space programs, the annular aerospike engine and the early (proposal-stage) development of the Space Shuttle main engine. Downsizing During continued downsizing in the 1980s and 1990s, Rockwell International shed several parts of the former North American Rockwell corporation. The aerospace entities of Rockwell International, including the former NAA and Rocketdyne, were sold to Boeing in 1996. Rocketdyne became part of Boeing's Defense division. In February 2005, Boeing reached an agreement to sell what was by then referred to as "Rocketdyne Propulsion & Power" to Pratt & Whitney of United Technologies Corporation. The transaction was completed on August 2, 2005. Boeing retained ownership of Rocketdyne's Santa Susana Field Lab. GenCorp purchased Pratt & Whitney Rocketdyne in 2013 from United Technologies Corporation, and merged it with Aerojet to form Aerojet Rocketdyne. Power generation In addition to its primary business of building rocket engines, Rocketdyne has developed power generation and control systems. These included early nuclear power generation experiments, radioisotope thermoelectric generators (RTG), and solar power equipment, including the main power system for the International Space Station.
