Kosmos 11 ({{langx|ru|Космос 11}} meaning Cosmos 11), also known as DS-A1 No.1 was a technology demonstration satellite which was launched by the Soviet Union in 1962. It was the eleventh satellite to be designated under the Kosmos system, and the fourth spacecraft launched as part of the DS programme to successfully reach orbit, after Kosmos 1, Kosmos 6 and Kosmos 8. Its primary mission was to demonstrate technologies for future Soviet military satellites.{{cite web |url=http://www.astronautix.com/craft/dsa1.htm |title=DS-A1|last=Wade|first=Mark|publisher=Encyclopedia Astronautica|access-date=25 May 2009|url-status=dead|archive-url=https://web.archive.org/web/20120617154230/http://www.astronautix.com/craft/dsa1.htm |archive-date=17 June 2012}}
