Progress 13 (Прогресс 13) was a Soviet uncrewed Progress cargo spacecraft, which was launched in May 1982 to resupply the Salyut 7 space station.

Spacecraft
Progress 13 was a Progress 7K-TG spacecraft. The thirteenth of forty three to be launched, it had the serial number 114. 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 was also used to adjust the orbit of the space station.

The Progress spacecraft had a dry mass of 6520 kg, which increased to around 7020 kg when fully fuelled. It measured 7.48 m in length, and 2.72 m in diameter. Each spacecraft could accommodate up to 2500 kg of payload, consisting of dry cargo and propellant. The spacecraft was powered by chemical batteries and could operate in free flight for up to three days, remaining docked at the station for up to thirty.

Launch
Progress 13 launched on 23 May 1982 from the Baikonur Cosmodrome in the Kazakh SSR. It used a Soyuz-U rocket.
