TGK PG (Russian: Транспортный Грузовой Корабль Повышенной Грузоподъемности (ТГК ПГ), lit. 'Cargo vehicle with increased payload capacity') is an automated cargo spacecraft project to replace Progress-MS as the Russian logistic vehicle to the ISS. It was requested for development to take advantage of the increased lift capacity of the Soyuz-2.1b.[1][2] The initial development contract was awarded to RSC Energia by Roscosmos on December 11, 2015. The spacecraft is not expected to fly before 2020.[3][4]
