This unique dual cannon is set up to fire on targets in the rear 90 degree arc of the Patrol Escort Refit and Fleet Patrol Escort Refit, and defaults to the Rapid Fire I firing mode. Like other cannons, the Aft-Firing Tempest Tail Gun can be modified by Scatter Volley and higher rank rapid Fire bridge officer abilities. The Aft-Firing Tempest Tail Gun is fused to its own slot, preventing removal, but it does not fill one of the ship's three aft weapons slots.
