H.M.S. REGULUS (J327) was an Algerine-class minesweeper built in Toronto in 1943 by order of the Royal Canadian Navy and originally to have been called HMCS Longbranch. Before completion at the shipyard she joined the 8 Navy Flotilla of the British Royal Navy. The ship sank on January the 12 in 1945 while on a mine sweeping operation after she struck a mine in the Southeastern part of Corfu. An attempt was made to tow the ship but the inflow of water continued and the ship sank approximately 45 minutes after the blast. One member of the ship was killed with many others reported injured. The wreck is situated between mainland Greece and the island of Corfu.

The wreck of the H.M.S. REGULUS is standing upright on a sandy bottom at a maximum depth of 63 meters. Although the mine struck the stern of the ship she remains in one piece with parts of the bridge and main superstructure covered by a large trawl net. An impressive site to witness are the 102mm cannon situated towards the bow and the two 20mm Oerlikon anti-aircraft guns situated towards the stern of the ship. The ships outer bridge is another impressive site including the compass which is clearly visible. Like with all wrecks after so many years the sea has done an excellent job transforming her into a reef. We would like to thank Deep Blue Divers and Alexandros Marketos for taking us to the dive site, helping us in our preparation, and ensuring the busy shipping lanes remained clear throughout the duration of our dive.
