Admiralty contractors were becoming increasingly discontented with the treatment that they were receiving from the Admiralty. AccessionNo.945. "H.M.S. "Hornet." Engineering, vol. 57, 2 March 1894, pp. 295-296. The twin-screw torpedo-boat destroyer Hornet built by Messrs. Yarrow and Co., of Poplar, for the British Government was the sister vessel of the Havock built by the same firm, the two being alike in all respects except with regard to their boilers and boiler fittings; that was to say the dimensions of their hulls and engines were alike throughout. Their armament consisted of one 12-pounder gun, two 6-pounder guns, one pair of 18-inch torpedo tubes on deck, and one 18-inch torpedo tube in the bow. Both vessels were fitted with two 18-inch by 26-inch by 39 and a half inch by 18-inch stroke inverted-vertical triple-expansion engines operating on steam supplied at 180 pounds per square inch by two marine locomotive boilers in the case of the Havock and eight Yarrow water-tube boilers in the Hornet.
