A RS-27a rocket engine powered the United Launch Alliance Delta II rocket that carried aloft the Italian Space Agency‘s COSMO/SkyMed-2 satellite from Vandenburg A.F.B. last Saturday night. The rocket was built by Pratt & Whitney Rocketdyne, a United Technologies company. Boosting the Delta II first stage, the RS-27A engine fired for slightly over four minutes. The engine produced 200,000 pounds of thrust. Pratt & Whitney Rocketdyne is a preferred provider of high-value propulsion, power, energy and systems solutions used in the main engines for the space shuttle, Atlas and Delta launch vehicles, missile defense systems and advanced hypersonic engines—East Hartford, Connecticut
