==Almaz-T (uncrewed)== [[Image:Almaz radar satellite.svg|thumb|Almaz radar satellite (based on Almaz space station).]] Following cancellation of the program, the Almaz station was reconfigured as an uncrewed heavy radar-carrying [[reconnaissance satellite]]. Three such satellites were launched, two of which functioned successfully in orbit.<ref name="rsw-almaz-t">{{Cite web |last=Zak |first=Anatoly |title=Almaz-T spacecraft |url=https://www.russianspaceweb.com/almazt.html |url-status=live |archive-url=https://web.archive.org/web/20121009023810/http://www.russianspaceweb.com/almazt.html |archive-date=October 9, 2012 |access-date=August 30, 2012 |website=RussianSpaceWeb.com }}</ref> ===Almaz-T=== '''Almaz-T''' β The first Almaz-T blasted off from Baikonur on October 29, 1986. It did not reach orbit due to the failure of the first and second stages of the Proton launcher to separate. The safety system then destroyed the vehicle. ===Almaz-T2 (Kosmos 1870)=== '''[[Kosmos 1870]]''' β On July 25, 1987, Almaz-T2, the second Almaz-T spacecraft, successfully reached orbit with an inclination 71.92 degrees toward the Equator and it was officially identified as Kosmos-1870. The spacecraft functioned for two years, providing [[Imaging radar|radar imagery]] with a resolution down to 25 meters, until it was deorbited on July 30, 1989. It was the first <!--private {{dubious}}--> commercial radar satellite, according to Art Dula, chairman of [[Excalibur Almaz]], who worked in a company marketing the radar images gathered by the satellite.<ref name=mbEA1>{{cite web|title=Interview with Art Dula (Chairman Excalibur Almaz) β Part 1|url=http://vimeo.com/43503094|publisher=moonandback.com (vimeo.com)|access-date=4 September 2012}}</ref> ===Almaz-1=== '''[[Almaz-1]]''' β The third Almaz-T spacecraft was launched on March 31, 1991, under the name Almaz-1. After the launch a failure of the communications antenna designed to downlink the imagery via the [[Luch (satellite)|Luch]] relay satellite was noted. Also one of the solar panels failed to deploy completely, leaving the main radar panel of the spacecraft partially blocked. After 18 months of successful work the Almaz-1 was deorbited on October 17, 1992, over the Pacific Ocean.{{Clarify|date=March 2014}} [[image:Almaz-1A.jpg|thumb|Almaz-1A]] ===Almaz-2=== '''[[Almaz-2]] (Almaz-1V)''' β Not flown. It had a new radar that would have provided a resolution of 5 to 7 meters. In addition, an optical-electronic payload on the station would have been capable of producing imagery with a resolution of 2.5 to 4 meters.
