Description says: “Destroy 3 ships with kinetic weapons.”
Detailed notes say: “You must use any railgun to complete the task.”
Using the Kinetic Supercharger does not complete this contract. Suggest to either change the description to mention railguns only (which raises the issue that the Coil Mortar is categorized as a rail gun internally so it can be used) or better to change the mission to allow use of any type of kinetic weapon and adjust the detailed mission notes accordingly.
