Delta III

Delta III was an expendable launch vehicle made by Boeing. Payload to GTO (Geostationary-Transfer Orbit) was doubled versus the Delta II but the consecutive failures of the initial Delta IIIs, combined with the more-advanced Delta IV program and the continuing success of the Delta II, left the Delta III as an interim vehicle. Under the four-digit designation system from earlier Delta rockets, the Delta III is classified as the Delta 8930.
