The Delta 2 rocket
SPACEFLIGHT NOW/BOEING FACT SHEET
Posted: November 20, 2000
Boeing will use a Delta 2 7320-10 to launch the Earth Observing-1, SAC-C and Munin satellite for NASA.
Boeing manufactures Delta rockets in Huntington Beach, Calif., with final assembly in Pueblo, Colo. The 7320-10 two-stage launch vehicle has four major assemblies: the first stage, including main engine and three strap-on solid propellant rocket motors; interstage; second stage; and 10-foot diameter composite payload fairing. The Delta 2 is approximately 126 feet tall and eight feet wide.
An Aerojet AJ10-118K engine powers the second stage and burns Aerozine-50 fuel and nitrogen tetroxide oxidizer. Ignited at altitude, the engine has a vacuum-rated thrust of 9,815 pounds.
The Boeing family of launch vehicles is derived from the Delta family of rockets built and launched since 1960. In that time 281 Deltas have been launched.
Delta 2 rockets can be configured as two- or three-stage vehicles depending on mission requirements. The latest version, the Delta 2 7925 model, can boost 3,965 pounds (1800 kg) to geosynchronous transfer orbit (GTO).
Today, Boeing has a growing list of commercial customers, including Hughes Space and Communications International, Inc., Space Systems/Loral, and Motorola. Delta rocket were used to launch 28 satellites to form the cornerstone of the Globastar system.
To serve its commercial customers, Boeing has agreements with the U.S. Air Force and NASA for the use of two government-owned launch pads at Space Launch Complex 17, Cape Canaveral Air Station, Fla., and one pad at Space Launch Complex 2, Vandenberg Air Force Base, Calif.
Major subcontractors include: Alliant Techsystems, Magna, Utah, graphite epoxy motors for boost assist; Aerojet, Sacramento, Calif., second-stage engine; Thiokol, a subsidiary of Cordant Technologies, Elkton, Md., third-stage solid rocket motor; and L3 Communications Space & Navigation, Teterboro, N.J., Redundant Inertial Flight Control Assembly (RIFCA) provides course and attitude control.
