Liftoff will occur from Space Launch Complex-37 at Air Force Station (CCAFS), FL. manufacturing efficiency and streamlined mission and vehicle integration to meet customer launch requirements. The Delta IV Medium+ (4,2) The twin GSSAP , built by Orbital ATK, will be a space-based capability operating in the near- regime supporting U.S. Strategic configuration was used for the inaugural Delta IV flight and has become Command space surveillance operations, as a dedicated Space Surveillance Network (SSN) sensor, GSSAP satellites will support Joint Functional Component the most versatile in the Delta IV fleet, launching national security, Command for Space (JFCC SPACE) tasking to collect space situational awareness data allowing for more accurate tracking and characterization of man-made civil and commercial missions. orbiting objects. From a near-geosynchronous orbit, they will have a clear, unobstructed and distinct vantage point for viewing Resident Space Objects (RSOs) without the interruption of weather or the atmospheric distortion that can limit ground-based systems. GSSAP satellites will operate near the geosynchronous belt First Launch: Nov. 20, 2002 and will have the capability to perform Rendezvous and Proximity Operations (RPO). RPO allows for the space vehicle to maneuver near a resident space object Launches to date: 13 of interest, enabling characterization for anomaly resolution and enhanced awareness, while maintaining flight safety. Data from GSSAP will uniquely contribute to timely and accurate orbital predictions, enhancing our knowledge of the geosynchronous orbit environment, and further enabling space flight safety to include Performance to GTO: 6,160 kg (13,580 lb) satellite collision avoidance. Performance to LEO-Reference: 12,900 kg (28,440 lb)

GSSAP satellites will communicate information through the world wide Air Force Satellite Control Network (AFSCN) ground stations, then to Schriever Air Force Base, CO where 50th Space Wing satellite operators of the 1st Space Operations Squadron (1 SOPS) will oversee day-to-day operations.

Two GSSAP satellites were previously launched aboard a ULA Delta IV M+ (4,2) rocket from CCAFS on July 28, 2014.

Payload Fairing (PLF) The PLF is a composite bisector (two-piece shell), 4-meter diameter fairing. The PLF encapsulates the spacecraft to protect it from the launch environment on ascent. The vehicle’s height, with the 38.5-ft tall PLF, is approximately 206 ft.

Delta Cryogenic Second Stage (DCSS) The DCSS stage propellant tanks are structurally rigid and constructed of aluminum ring forgings and spun-formed aluminum domes. It is a cryogenic liquid hydrogen/-fueled vehicle, and uses a single RL10B-2 engine that produces 24,750 lb of thrust. The DCSS cryogenic tanks are insulated with a combination of spray-on and bond-on insu- lation, and helium-purged insulation blankets. An equipment shelf attached to the aft dome of the DCSS liquid oxygen tank provides the structural mountings for vehicle electronics. MISSION OVERVIEW

Booster The common core (CBC) consists of the RS-68A engine, the engine section and thermal shield, the liquid hydrogen (LH2) tank, the centerbody, and the liquid oxygen (LO2) – 33rd Delta IV Launch tank. The Delta IV booster tanks are structurally rigid and constructed of isogrid aluminum With more than a century of combined heritage, United Launch Alliance is barrels, spun-formed aluminum domes and machined aluminum tank skirts. Delta IV booster the nation’s most experienced and reliable . ULA – 110th ULA Launch propulsion is provided by the throttleable RS-68A engine system, designed and manufactured has successfully delivered more than 100 satellites to orbit that provide by Pratt & Whitney , is the largest existing hydrogen-burning engine and delivers critical capabilities for troops in the field, aid meteorologists in tracking 702,000 lb of thrust at sea level. severe weather, enable personal device-based GPS navigation and unlock the mysteries of our . Solid Rocket Motors (SRM) Two solid rocket motors, combined, produce an additional 517,085 lbs of thrust at liftoff. The SRMs are 5 ft in diameter and 53 ft long and constructed of a graphite-epoxy composite. Join the conversation: The SRMs are connected to the booster by two ball-and-socket joints and structural thrusters. AFSPC-6 will be the first Delta IV M+(4,2) flight supporting one fixed SRM and one vectorable SRM. ULALaunch.com
