Progress 15 ({{Langx|ru|Прогресс 15|italic=yes}}) was a Soviet uncrewed Progress cargo spacecraft, which was launched in September 1982 to resupply the Salyut 7 space station.
Spacecraft
Progress 15 was a Progress 7K-TG spacecraft. The 15th of forty three to be launched, it had the serial number 112.{{cite web|url=http://space.skyrocket.de/doc_sdat/progress.htm |title=Progress 1 - 42 (11F615A15, 7K-TG)|first=Gunter|last=Krebs|work=Gunter's Space Page|access-date=26 November 2010}}{{cite web|url=http://planet4589.org/space/log/launchlog.txt |title=Launch Log|last=McDowell|first=Jonathan|work=Jonathan's Space Page|access-date=26 November 2010}} The Progress 7K-TG spacecraft was the first generation Progress, derived from the Soyuz 7K-T and intended for uncrewed logistics missions to space stations in support of the Salyut programme. On some missions the spacecraft were also used to adjust the orbit of the space station.
The Progress spacecraft had a dry mass of {{convert|6520|kg}}, which increased to around {{convert|7020|kg}} when fully fuelled. It measured {{convert|7.48|m}} in length, and {{convert|2.72|m}} in diameter. Each spacecraft could accommodate up to {{convert|2500|kg}} of payload, consisting of dry cargo and propellant. The spacecraft were powered by chemical batteries, and could operate in free flight for up to three days, remaining docked to the station for up to thirty.{{cite book|last1=Hall|first1=Rex D.|last2=Shayler|first2=David J.|title=Soyuz: A Universal Spacecraft|year=2003 |publisher=Springer-Praxis|isbn=1-85233-657-9|pages=239–250}}
