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).
The Delta II is an expendable launch, medium-lift vehicle that is primarily used to launch (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.
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.
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 Commands 45th Space Wing, headquartered at Patrick AFB, Fla., and 30th Space Wing, Vandenberg AFB, Calif., are responsible for the Delta IIs military launch missions.
