Direct link to the 3D model: Exchange3D media store More details: This is a very detailed model of the Delta II Launch Vehicle and supporting Launch Pad. It includes internal components, color and bump texture maps. The supporting geometry includes the grounds immediately around the launch pad (as rendered). Mission The Delta II is an expendable launch, medium-lift vehicle that is primarily used to launch Navstar Global Positioning System (GPS) satellites into orbit, providing navigational data to military users. Additionally, the Delta II launches civil and commercial payloads into low-earth, polar, geo-transfer and geosynchronous orbits. Features The Delta II stands a total height of 125.9 feet. The payload fairing – the shroud covering the third stage and the satellite – is 9.5 feet wide to accommodate the GPS satellite. A 10-foot wide fairing also is available for larger payloads. Six of the nine solid-rocket motors that ring the first stage separate after one minute of flight, and the remaining three ignite, then separate, after burnout, one-minute later. Background The Delta launch vehicle family began in 1959 when NASA's Goddard Space Flight Center awarded a contract to Douglas Aircraft Company to produce and integrate 12 space-launch vehicles. The Delta used components from the U.S. Air Force's Thor intermediate-range ballistic missile as its first stage and the U.S. Navy's Vanguard launch-vehicle program as its second. The first Delta was launched from Cape Canaveral AFS May 13, 1960, and had the ability to deliver a 100-pound spacecraft into geostationary transfer orbit. In January 1987 the Air Force awarded a contract to McDonnell Douglas for construction of 18 Delta IIs to launch Navstar GPS satellites, originally programmed for launch on the space shuttle. Since then, the order expanded to accommodate 28 GPS satellite-dedicated launch vehicles. The first Delta II was successfully launched February 14, 1989, at Cape Canaveral. There are two primary versions of the Delta II (6925 and 7925). The Delta 6925, the first version, carried the initial nine GPS satellites into orbit. The Delta program has had more than 245 successful domestic and foreign military and commercial launches, and has accomplished many firsts over the years. These include the first international satellite, Telstar I, in 1962; the first geosynchronous-orbit satellite, Syncorn II, in 1963; and the first commercial communications satellite, COMSAT I, in 1965. The Delta II is launched primarily from Cape Canaveral AFS, Fla., but is also launched from Vandenberg AFB, Calif. Members of Air Force Space Command's 45th Space Wing, headquartered at Patrick AFB, Fla., and 30th Space Wing, Vandenberg AFB, Calif., are responsible for the Delta II's military launch missions..
