HMS Bellona was a Boadicea-class scout cruiser constructed for the Royal Navy, launched on 20 March 1909 and completed in February 1910. Displacing approximately 3,350 long tons, the vessel measured 405 feet in length with a beam of 41 feet 6 inches and a draught of 14 feet. Powered by two Parsons steam turbines generating 18,000 indicated horsepower from 12 Yarrow boilers burning coal and fuel oil, Bellona could reach a maximum speed of 25 knots, designed to serve as a flotilla leader for destroyer groups. Her armament comprised six 4-inch (102 mm) breech-loading guns positioned for optimal coverage, supplemented by four 3-pounder (47 mm) quick-firing guns, and two submerged 21-inch torpedo tubes. During wartime, her firepower was increased with four additional 4-inch guns and a 3-inch anti-aircraft gun, later replaced by a 4-inch gun in 1918. Her light protective deck, only 1 inch thick on the slopes and 0.5 inches on flat surfaces, reflected her role as a fast scout, with a conning tower armored with four inches of protection. Constructed at Pembroke Royal Dockyard, Bellona was initially assigned to the 2nd Destroyer Flotilla and later transferred to the 1st Battle Squadron, serving prominently during World War I. She participated in the Grand Fleet at Scapa Flow and was present at the Battle of Jutland in 1916, though she did not engage in combat. In 1917, she was converted into a minelayer, conducting four sorties to lay mines in the Kattegat, laying a total of 306 mines. Her service concluded with her transfer to reserve in 1919, and she was sold for scrap in 1921. Her career highlights the Royal Navy’s emphasis on fast, lightly protected scout vessels during the early 20th century, though her relatively slow speed and limited armor underscored the evolving nature of naval warfare during this period.
