Emerson Electric TAT Armament System.

From Arcforums:

The next two pictures are proposals by Emerson Electric. The first is of a potential 360-degree fire suppression system for the HH-3E, utilizing the TAT-102 series armament subsystem fitted to the helicopter's rear cargo ramp. The second is a proposal for the TAT-136 on the CH-53A. This subsystem involved the installation of one turret in each of the aircraft's sponsons, each fitted with one 20mm Mk 12 cannon, 20mm M24 cannon, or 30mm XM140 cannon.
