The Dome Gunnery Trainer on Pembrey Airfield was erected c1941 and used as a simulator to train air gunners in shooting down enemy fighters. The interior was originally whitewashed and lights projected on to the domed roof simulated aircraft lights, while a 'gun' was used to fire a light beam.

The dome is approximately 10m high, of concrete with rendered exterior. The entrance leads into a single domed chamber. The metal framework of a former screen above the doorway has survived, but the interior has been stripped of its original wall surfaces.

Listed in a high grade for its exceptional historic interest as the only surviving World War II air defence simulator in Wales.
Scheduled Ancient Monument CM248.
