Port HHZ (original) (raw)

Port HHZ was a shore establishment of the Royal Navy during the Second World War. It was based at Loch Cairnbawn, Scotland, and was established in 1942. The base was heavily involved in the training for the X-Craft operations (Operation Source) to sink the German battleship Tirpitz. From July 1943, the craft worked up from HMS Bonaventure at Port HHZ. Capital ships of the Home fleet acted as target ships at Port HHZ. The Boom Defence organisation were also heavily involved in surrounding these ships with nets and providing net defences and equipment for the trials.
