The '''Delta G''', or '''Thor-Delta G''' was an American [[expendable launch system]] used to launch two biological research satellites in 1966 and 1967. It was a member of the [[Delta (rocket family)|Delta]] family of rockets.

The Delta G was a two-stage derivative of the [[Delta E]]. The first stage was a [[PGM-17 Thor|Thor]] missile in the [[Thor DSV-2|DSV-2C]] configuration and the second stage was a [[Delta E (rocket stage)|Delta E]]. Three [[Castor-1]] [[solid rocket booster]]s were clustered around the first stage. The solid-fuel upper stage used on the Delta E was not used on the Delta G.

Both launches occurred from [[Cape Canaveral Air Force Station]] [[Cape Canaveral Air Force Station Launch Complex 17|Launch Complex 17]]. The first was from pad 17A on 14 December 1966 at 19:20 GMT, with [[Biosatellite 1]]. At 22:04 on 7 September 1967, [[Biosatellite 2]] was launched from pad B on the second Delta G.<ref>{{Cite web|last=Wade|first=Mark|title=Delta|url=http://www.astronautix.com/lvs/delta.htm|url-status=dead|archive-url=https://web.archive.org/web/20080724064027/http://www.astronautix.com/lvs/delta.htm|archive-date=2008-07-24}}</ref><ref>{{Cite web|last=Krebs|first=Gunter|title=Thor Family|url=https://space.skyrocket.de/doc_lau_fam/thor.htm|url-status=live|access-date=2021-12-21|website=Gunter's Space Page|language=en|archive-url=https://web.archive.org/web/20070806202728/http://space.skyrocket.de:80/doc_lau_fam/thor.htm |archive-date=2007-08-06 }}</ref>
