The upgraded '''Progress M''' ([[GRAU]]: 11F615A55, manufacturer's designation: 7K-TGM) was first launched in August 1989. The first 43 flights all went to [[Mir]]; following Mir's re-entry, Progress was used as the resupply vehicle for the [[International Space Station]]. As of December 2020, there have been over 80 flights (over different configurations) to the ISS and more are scheduled.<ref name="Nasa Launch Schedule">{{cite web|title=NASA Launch Schedule and NASA|url=http://www.nasa.gov/missions/highlights/schedule.html}} {{PD-notice}}</ref>

The Progress M is essentially the same spacecraft as the Progress, but it features improvements based on the [[Soyuz-T]] and [[Soyuz-TM]] designs. It can spend up to 30 days in autonomous flight and is able to carry {{cvt|100|kg}} more. Also, unlike the old Progress crafts, it can return items to [[Earth]]. This is accomplished by using the [[VBK-Raduga]] capsule, which can carry up to {{cvt|150|kg}} of cargo. It is {{cvt|1.5|m}} long and {{cvt|60|cm}} in diameter and has a "[[dry mass]]" of {{cvt|350|kg}}. Progress M can also dock to the forward port of the station and still transfer fuel. It uses the same [[Space rendezvous|rendezvous system]] as the Soyuz, and it features solar panels for the first time.

In addition to the traditional Progress-M spacecraft, three modified "[[space tug]]" versions were built to deliver modules to the ISS. These variants lacked a pressurized cargo section and had a heavily modified tanker section. [[Progress DC-1]] delivered ''[[Pirs (ISS module)|Pirs]]'' in 2001, [[Progress M-MIM2]] delivered ''[[Poisk (ISS module)|Poisk]]'' in 2009 and [[Progress M-UM]] delivered ''[[Prichal (ISS module)|Prichal]]'' in 2021.
