original Brennan Torpedo is exhibited at the Royal Engineers Museum in Chatham, Kent. However, traces of the installation at Fort Camden in County Cork are visible to this day. The launching rails at Cliffe Fort in Kent are crossed by the public footpath and though heavily rusted are very easy to get close to. There is also a display at Lei Yue Mun Fort in Hong Kong which shows a replica Brennan Torpedo with the side cut away so the workings are visible.
