MUOS-4 launch

The US Navy/Lockheed Martin MUOS-4 communications satellite flew into orbit on a United Launch Alliance Atlas V rocket on September 2, 2015 from Cape Canaveral.

The U.S. Navy’s Mobile User Objective System (MUOS) is a next-generation narrowband tactical satellite communications system designed using a combination of orbiting satellites and relay ground stations to significantly improve communications for U.S. forces on the move. MUOS will provide new beyond-line-of-sight communications capabilities, with smartphone-like simultaneous voice, video and data – to connect military users almost anywhere around the globe.

This mission was launched aboard an Atlas V 551 configuration vehicle, which includes a 5-meter diameter payload fairing along with five Aerojet Rocketdyne solid rocket motors attached to the Atlas booster. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.

Pratt & Whitney TF33 celebrates its 55th year

The now-antique TF33 turbofan engine just keeps going.

The TF33 and its commercial variant, the JT3D, celebrated its 55th anniversary in June 2015. The JT3D was the first turbofan engine designed and produced by Pratt & Whitney. When it was introduced, the engine had approximately 50 percent more take-off thrust, 25 percent more climbing power and 20 percent greater power at maximum cruise than previous engines.

First introduced on the B-52H Stratofortress, the TF33 continues to serve that fleet today and is also on E-3 Sentry AWACS (Airborne Warning and Control System), the E-8 Joint Stars and some special mission aircraft. In addition to the Air Force fleet, the TF33 powers NATO AWACs and KC-135s for Chile. Over the past six decades, it also has powered the C-135, C-141, EC-135, RB-57, E3A, C-135, KC-135, VC-137 and EC-18 ARIA.
