TheDelta 4000 series was an Americanexpendable launch system which was used to conduct twoorbital launches in 1989 and 1990. It was a member of theDelta family of rockets. Although several variants were put forward, only the Delta 4925 was launched.^[2] The designations used afour digit numerical code to store information on the configuration of the rocket. It was built from a combination of spare parts left over from earlier Delta rockets, which were being retired, and parts from theDelta II 6000-series, which was just entering service.

Configuration

[edit]

The first stage was theMB-3-III poweredExtended Long Tank Thor, previously flown on the1000-series. NineCastor-4A solid rocket boosters were attached to increase thrust at lift-off, replacing the less powerfulCastor-4 boosters used on the 3000 series. TheDelta-K was used as a second stage. AStar-48B PAM-D was used as a third stage, to boost payloads intogeosynchronous transfer orbit.

Launches

[edit]

Two Delta 4000 launches occurred fromLaunch Complex 17B atCape Canaveral. The first launchedMarco Polo 1 forBSkyB, and the second launchedINSAT-1D for theIndian Space Research Organisation. Both were successful.^[3]^[4]^[5]
