HMS B10

HMS B10 was a Royal Navy B class submarine, built at Vickers, Barrow-in-Furness, launched 23 March 1906 and completed 28 April 1906.

B10 was deployed to the Mediterranean soon after the outbreak of World War I. Due to the lack of spare parts this group of submarines were not used after September 1915.

On 9 August 1916 B10 was sunk by aircraft of the Austrian Naval Air Service (Kaiserliche und Königliche Seeflugwesen) while under repair at Venice. She was lost as she was tied up after taking part in the blockade of Pula alongside the Italian cruiser Marco Polo, which was acting as a depot ship. B10 was the first submarine to be sunk by an aircraft.

An attempt to repair the bomb damage was abandoned after a welding torch ignited a fuel tank resulting in further damage. The submarine was then sold to be broken up.
