HMS M30  HMS M30 was a Royal Navy "M29"-class monitor of the First World War. The availability of ten 6 inch Mk XII guns from the "Queen Elizabeth"-class battleships in 1915 prompted the Admiralty to order five scaled down versions of the "M15"-class monitors, which had been designed to use 9.2 inch guns. HMS "M30" and her sisters were ordered from Harland & Wolff, Belfast in March 1915. Launched on 23 June 1915, she was completed in July 1915. Upon completion, HMS "M30" was sent to the Mediterranean. Whilst enforcing the Allied blockade in the Gulf of Smyrna, HMS "M30" came under fire from the Austro-Hungarian howitzer battery 36 supporting the Turkish, and was sunk on 14 May 1916.
