Rocketdyne is the prominent enterprise in the range of the development and the production of rocket engines in the USA. The enterprise belonged for a long time to North American aviation (NAA). The NAA fused with Rockwell International, however in December 1996 Boeing was sold. In February 2005 Boeing reached an agreement, in order to sell Rocketdyne at Pratt & Whitney. This transaction was locked on 2 August 2005.

To examine Rocketdyne from NAA in the direct post-war period based around the German V2-Rakete and to adapt their drive to the standards of the "Society OF of automotives Engineers (SOW)" and to the American construction conditions. They used the same principle of the separate combustion chambers/a splashes of the V2-Triebwerk around a very much larger rocket engine for the Navaho rocket project to build. This work had been regarded in the Vierzigern as unimportant and was also very badly financed, but the beginning of the Korea war changed the priorities. Navajo came however into always new difficulties and into the late was finally adjusted, as which development of the talking clay/tone rocket program (essentially a many larger V-2) began. However the rocket engine of Rocketdyne, well-known more reliable as "A-5" or "NAA75-110", was demonstrably substantially than the talking clay/tone rocket engine developed up to then. Thereupon the rocket with the "A-5" was reequipped, although the rocket developed from it had a substantially shorter range. As the rocket production separated the NAA Rocketdyne was taken up 1955 as its own subsidiary.

Rocketdyne"´s next large development was their first complete reconstruction, which "S-3D", which was developed parallel to the V-2 type A series. The S-3 was used with the Jupiter rockets, essentially an advancement the talking clay/tone and later selected for the substantially stronger Thor rocket. A still larger construction, the LR89/LR105 was used with the Atlas rocket. Both, Thor and Atlas, had a short career with the military, however for the Satellitenstart during the fifties and the sixties in different variants were used. A variant, the "Thor delta" became the basis for the current delta rocket series, although since the late Sechzigern the delta with the Thor nearly nothing more in common had. Although the Original-S-3-Triebwerk was used in some delta variants, nevertheless most used the further developed RS-27-Design, which was originally developed as single engine around the three-fold engine the Atlas to replace.

Rocketdyne became the main system manufacturer for the efforts for development of NASA, supplies the large engines for the Saturn rocket (and potenziell the new fact rocket). Rocketdynes H-1-Triebwerk was used in the main stage of the Saturn I, which essentially consists of a group of eight Jupiter. The F-1 was in the first stage of the Saturn V, while the J-II was used in the second and third stage. Around 1965 Rocketdyne built the very most US-American rocket engines and the staff grew on 65.000. This growth seemed to continue presumably also into the Siebzigern in such a way, when the addition for the main rubbing work of the space shuttle was achieved. But the rapid decrease both the military and the civilian orders led to a corresponding Verschlankung of the enterprise. North American, now to a large extent a space travel supplier and almost exclusively bound to the space shuttle, fused 1966 with Rockwell to the earlier "North American Rockwell", from which later then Rockwell International became, with Rocketdyne than a main section.

When the Verschlankung continued in the Achtzigern and Neunzigern, Rockwell lost some parts of the earlier NAA Imperiums. As the first 1980 the "general aviation" - the "Saberliner" followed section and 1983 - went to Businessjet section. The remainder of the NAA was sold 1996 together with Rocketdyne at Boeing. Rocketdyne was a part "Boeing Integrated Defense of system" to it on 2 August 2005 at Pratt & Whitney was sold.

Some the rocket engines developed by Rocketdyne:

  • H-1 (kerosene/liquid oxygen (LOX)) used of the Saturn I, IB, Jupiter and unite delta rockets
  • F-1 (Kerosin/LOX) uses from the Saturn V.
  • J-2 (LH2/LOX) uses V and Saturn IB. from Saturn
  • SSME (LH2/LOX) the space shuttle master engine
  • RS-68 (LH2/LOX) uses IV in the first stage of the delta
  • RS-27A (Kerosin/LOX) uses delta II/CIII and Atlas in the delta

Many Rocketdyne engines were tested in the Santa Susana Field Laboratory (SSFL) by Boeing. This is in the "Santa Susana Mountain rank" and the "Simi Hills" (northwest from Los Angeles in California and Chatsworth). Rocketdyne, that now as "Pratt & Whitney Rocketdyne, Inc." when 100 percent daughter of the United Technologies corporation firmiert, park in California with addresses in west Palm Beach in Florida, Huntsville (Alabama) has its head office in Canoga, Kennedy space center in Florida and Stennis space center in Mississippi.

Rocketdyne operated many projects and programs on the Edwards' air Force cousin in the Antelope Valley in the California desert with pink moon, together with the aviation enterprise Lockheed Martin.
