The company ULA (United Launch Alliance ) launched on 11 March at 23:38 UTC rocket Delta IV M + (4,2) (mission D353) from the ramp SLC-37B Air Force Base in Cape Canaveral. The charge was the secret military satellite NROL-27.
NROL-27
The NROL-27 is a satellite of the National Reconnaissance Office (NRO). All the features of the mission are classified, but is believed to be a satellite of the military network SDS (Satellite Data System ) . The constellation of communications satellites SDS is bringing back to Earth according to data from other NRO military satellites (such as KH-11B). It is also believed that connect different bases and air force units. Today is the third service generation satellite system, SDS-3, consisting of five units. Two satellites are positioned in geostationary and other Molniya-type orbits. The NROL-27 will carry out its mission from the geostationary orbit. The latest satellite SDS was launched in 2007.

Delta IV M + (4,2)
The Delta IV M + (4,2) is a pitcher for the Delta IV series with two stages. Has only CBC (Common Booster Core) in the first stage, a second stage of 4 feet in diameter, a cap also 4 meters and two solid rocket SRM (Solid Rocket Motor ) GEM 60 . The Delta IV mployment hydrogen and liquid oxygen in two phases and, as the Atlas V uses a modular design to accommodate various payloads. These modules are called CBC (Common Booster Core ). In total there are five versions of the Delta IV.

The Delta IV family (ULA).
The first stage uses the cryogenic engine RS-68 (manufactured by Pratt and Whitney Rocketdyne). The RS-68 was designed during the 90's and has a vacuum thrust of 3312 kN, much higher than the SSME (2278 kN) of shuttle. Hydrogen engine is the most powerful liquid oxygen and history.
The second stage of the Delta M + (4.2) is based on the Delta III and uses a motor RL10B-2, also manufactured by Pratt and Whitney Rocketdyne, with a thrust of 110 kN and a specific impulse of 462 s. This engine is based on the venerable RL-10 developed in the late 50's and has been used also in the Atlas rocket and the Centaur stage.

The Delta IV M + (4,2) SRM uses two manufactured by Alliant Techsystems, also known as GEM-60 (Graphite-Epoxy Motors ) , based on the GEM-46 Delta III. Work for 90 seconds and are 1.5 meters in diameter, a thrust of 826.6 kN and a specific impulse of 275 s each.
