Italian firms D-Orbit and Group of Astrodynamics for the Use of Space Systems (GAUSS) as well as U.S. companies Momentus, Northrop Grumman Innovation Systems and Spaceflight Inc. have developed, manufactured, tested or flown orbital transfer vehicles. Seven additional companies are preparing to enter the market with initial flights scheduled in the next three years. The companies are: Atomos, Exotrail, Firefly Aerospace, Launcher, Space Machines, Exolaunch and Impulse Space.
Most orbits that would make the extra cost of a smallsat launcher acceptable, would be too much for a space tug to get to from another orbit IMO. Space tugs could be better used as mission extention vehicles.I do think both will service very small markets, and that seems to me the main reason why they claim that constellations, the only market segment with considerable growth at the moment, would be their main customer. In reality, constellations will not make extensive use of either smallsat launchers or space tugs.
Russia could build a batch of 150 space tugs to be launched into space aboard the Soyuz-2.1a to dock with derelict Soviet-era communications satellites in order to deorbit those satellites.
