The Soviet space station programs, Almaz and Salyut, both envisioned further generations of space stations which would have long-term crews and be regularly stationed for years. The biggest limitation to the early Salyut stations (1, 3, 4, and 5) and the American station, Skylab, was that the ability to resupply them was very limited. The ability to resupply these early stations was limited to space in each of the manned vessels that visited them. If stations were to be manned by larger crews for longer durations they would need to be regularly resupplied from unmanned logistics craft. The Progress spacecraft was the easiest choice for an initial unmanned logistics craft since it was simply derived from the already developed and flown Soyuz-T. The initial Progress 7K-TG model flew between 1978 and 1990 and over the course of its lifetime flew 43 resupply missions to Salyut 6, 7, and Mir.

The Prohres 7K-TG is an approximation of the Progress 7K-TG and is meant to resupply long-term space stations in LKO (Low Kerbin Orbit). It primarily carries 63-108 units of liquid fuel, 77-132 units of oxidizer, and up to 100 units of monopropellent. It’s assumed that some of that range is used by the Prohres during rendezvous and docking with its target station. Like the Sangh 7K-T it lacks solar panels so its orbital mission prior to docking must be kept efficiently short.

Built in the VAB in KSP version 1.3.0.
