Docking was originally to have been at Poisk, but the automatic docking mechanism at this port was malfunctioning.

This was an unmanned test flight to the ISS. It was intended to test a modification of the launch abort system for integration with the Soyuz-2.1a launch vehicle.

Traditionally, the Soyuz launcher is turned on the launch pad to set the flight azimuth. Soyuz-2 does this by performing a roll maneuver during its flight to change direction. Since this maneuver may trigger the launch abort system used with the older launcher, Soyuz MS-14 will test a solution for this issue. If the test is successful, the new configuration will become standard beginning with Soyuz MS-16.

Upgraded navigation and propulsion systems will also be tested. Several crew support systems will be removed to enable this test to carry more cargo than would be normal.
