Soyuz MS-14 is a Soyuz spaceflight to the International Space Station planned for September 2019.[1] It will carry no crew members, as it is intended to test a modification of the launch abort system for integration with the Soyuz-2.1a launch vehicle.[2] Unlike the traditional Soyuz-FG launcher which is turned on its launchpad to set azimuth of its flight, Soyuz-2 performs a roll maneuver during its flight to change direction. The maneuver may trigger the analog launch abort system designed for Soyuz-FG. Soyuz MS-14 will test a solution for this issue. The 14th flight of Soyuz MS will be the 143rd flight of a Soyuz spacecraft. If all goes well, future crewed missions will use the new configuration starting with Soyuz MS-16 in early 2020.[1]

Besides testing the integration of the new launcher and the abort system Soyuz MS-14 will also test an upgraded navigation and propulsion control system.[3] The results of the testing will be used in the design of Soyuz GVK, an unmanned cargo delivery and return spacecraft, tentatively scheduled to be launched for the first time in 2022.[3] Soyuz GVK is being designed to be able to deliver 2,000 kg to orbit and return 500 kg back to Earth. Unlike preceding and future Soyuz MS spacecrafts Soyuz MS-14 will lack various crew support systems. This will allow Soyuz MS-14 to bring several times more cargo to the ISS than would be possible otherwise.
