Kosmos 611 ({{langx|ru|Космос 611}} meaning Cosmos 611), known before launch as DS-P1-Yu No.64, was a Soviet satellite which was launched in 1973 as part of the Dnepropetrovsk Sputnik programme. It was a {{convert|400|kg|adj=on}} spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.{{cite web|url=http://www.astronautix.com/craft/dsp1yu.htm|title=DS-P1-Yu|last=Wade|first=Mark|publisher=Encyclopedia Astronautica|access-date=2009-09-01|url-status=dead|archive-url=https://web.archive.org/web/20120602211924/http://www.astronautix.com/craft/dsp1yu.htm|archive-date=2 June 2012|df=dmy-all}}
Launch
Kosmos 611 was successfully launched into low Earth orbit at 09:29:58 UTC on 28 November 1973.{{cite web|url=http://www.astronautix.com/lvs/kosmos2.htm|title=Kosmos 2|last=Wade|first=Mark|publisher=Encyclopedia Astronautica|access-date=2009-09-01|url-status=dead|archive-url=https://web.archive.org/web/20120618125001/http://www.astronautix.com/lvs/kosmos2.htm|archive-date=18 June 2012|df=dmy-all}} The launch took place from Site 133/1 at the Plesetsk Cosmodrome,{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|last=McDowell|first=Jonathan|publisher=Jonathan's Space Page|access-date=2009-09-01}} and used a Kosmos-2I 63SM carrier rocket.
Orbit
Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1973-094A.{{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1973-094A|title=Cosmos 611|publisher=US National Space Science Data Center|work=NSSDC Master Catalog|access-date=2009-09-01}} The North American Aerospace Defense Command assigned it the catalogue number 06952.
Kosmos 611 was the sixty-seventh of seventy nine DS-P1-Yu satellites to be launched, and the sixty-first of seventy two to successfully reach orbit.{{cite web|url=http://space.skyrocket.de/doc_sdat/ds-p1-yu.htm|title=DS-P1-Yu (11F618)|first=Gunter|last=Krebs|publisher=Gunter's Space Page|access-date=2009-09-01}} It was operated in an orbit with a perigee of {{convert|264|km}}, an apogee of {{convert|466|km}}, 70.9 degrees of inclination, and an orbital period of 91.8 minutes. It remained in orbit until it decayed and reentered the atmosphere on 19 June 1974.{{cite web|url=http://www.planet4589.org/space/log/satcat.txt|title=Satellite Catalog|last=McDowell|first=Jonathan|publisher=Jonathan's Space Page|access-date=2009-09-01}}
