Rocketdyne Corporation var ett amerikanskt tillverkningsföretag som verkade inom försvars- och rymdfartsindustrin. De utvecklade och tillverkade raketmotorer som drevs av flytande bränsle åt både rymdfarkoster och robotvapen. Företaget försedde bland annat raketserierna Atlas, Delta, Redstone och Thor med raketmotorer.[3]
2005 hade Rocketdyne omkring 3 000 anställda och var bland annat verksamma i delstaterna Alabama, Florida, Kalifornien och Mississippi.[1]
Företaget grundades 1955 som ett dotterbolag till North American Aviation Inc. 1967 blev North American Aviation tillsammans med dotterbolagen Rocketdyne och Atomics International fusionerade med Rockwell-Standard Corporation och blev North American Rockwell[3], sex år senare blev de Rockwell International Corporation efter en fusion.[4] På 1990-talet drabbades den inhemska försvarsindustrin av låg efterfrågan på krigsmateriel samt att National Aeronautics and Space Administration (NASA) tvingades till budgetnedskärningar, det slutade med att Rockwell 1996 sålde av dotterbolaget inom försvars- och rymdfartsindustrin, där även North American Aviation och Rocketdyne ingick, till The Boeing Company för $3,2 miljarder.[5] I februari 2005 meddelades det att Boeing och United Technologies Corporation var överens om en affär rörande Rocketdyne, som då hette Rocketdyne Propulsion & Power, för $700 miljoner[1], affären slutfördes den 2 augusti samma år[6] och fick namnet Pratt & Whitney Rocketdyne[7].

In this photo, an RS-88 development rocket engine is being test fired at NASA's Marshall Space Flight Center in Huntsville, Alabama, in support of the Pad Abort Demonstration (PAD) test flights for NASA's Orbital Space Plane (OSP). The tests could be instrumental in developing the first crew launch escape system in almost 30 years. Paving the way for a series of integrated PAD test flights, the engine tests support development of a system that could pull a crew safely away from danger during liftoff. A series of 16 hot fire tests of a 50,000-pound thrust RS-88 rocket engine were conducted, resulting in a total of 55 seconds of successful engine operation. The engine is being developed by the Rocketdyne Propulsion and Power unit of the Boeing Company. Integrated launch abort demonstration tests in 2005 will use four RS-88 engines to separate a test vehicle from a test platform, simulating pulling a crewed vehicle away from an aborted launch. Four 156-foot parachutes will deploy and carry the vehicle to landing. Lockheed Martin is building the vehicles for the PAD tests. Seven integrated tests are planned for 2005 and 2006.
Installation of the F-1 Engine to the Saturn V S-IC Stage for Testing. Engineers at the Marshall Space Flight Center install the F-1 engines on the S-IC stage thrust structure at the S-IC static test stand. Engines are installed on the stage after it has been placed in the test stand. Five F-1 engines, each weighing 10 tons, gave the booster a total thrust of 7,500,000 pounds, roughly equivalent to 160 million horsepower.

The test of twin Linear Aerospike XRS-2200 engines, originally built for the X-33 program, was performed on August 6, 2001 at NASA's Stennis Space Center, Mississippi. The engines were fired for the planned 90 seconds and reached a planned maximum power of 85 percent. NASA's Second Generation Reusable Launch Vehicle Program , also known as the Space Launch Initiative (SLI), is making advances in propulsion technology with this third and final successful engine hot fire, designed to test electro-mechanical actuators. Information learned from this hot fire test series about new electro-mechanical actuator technology, which controls the flow of propellants in rocket engines, could provide key advancements for the propulsion systems for future spacecraft. The Second Generation Reusable Launch Vehicle Program, led by NASA's Marshall Space Flight Center in Huntsville, Alabama, is a technology development program designed to increase safety and reliability while reducing costs for space travel. The X-33 program was cancelled in March 2001.
