HMCS Terra Nova (DDE 259) was a that served in the Royal Canadian Navy and later the Canadian Forces from 1959 until 1997. After her final refit, she was a guided missile destroyer. She was the sixth ship of her class and the first Canadian war ship to bear the name Terra Nova. The ship's badge honours the Terra Nova River in Newfoundland as well as an earlier civilian ship, , which gained fame during a scientific exploration voyage to Antarctica. They are represented as a river and the Antarctic (symbolized by a penguin) on the ship's badge. Design and description Based on the preceding design, the Restigouche-class ships had the same hull and propulsion, but different weaponry. Initially the St. Laurent-class had been planned to be 14 ships. However the order was halved, and the following seven were redesigned to take into improvements made on the St. Laurent-class ships. As time passed, their design diverged further from that of the St. Laurent-class ships The ships had a displacement of , at deep load. They were designed to be long with a beam of and a draught of . The Restigouches had a complement of 214. The Restigouche-class ships were by powered by two English Electric geared steam turbines, each driving a propeller shaft, using steam provided by two Babcock & Wilcox boilers. They generated giving the vessels a maximum speed of . The Restigouche-class ships were equipped with SPS-10, SPS-12, Sperry Mk 2 and SPG-48 radar along with SQS-501 and SQS-503 sonar. Armament The Restigouche-class ships diverged from the St. Laurent-class ships in their weaponry. The Restigouche-class ships were equipped with two twin mounts of Vickers /70 calibre Mk 6 dual-purpose guns forward and maintained a single twin mount of 3-inch/50 calibre Mk 22 guns aft used in the preceding class. A Mk 69 fire control director was added to control the new guns. They were also armed with two Limbo Mk 10 mortars and two single Bofors 40 mm guns. However the 40 mm guns were dropped in the final design. The 3 in/70 mounting was placed in the 'A' position and the 3 in/50 mounting was placed in the 'Y' position. The destroyers were also equipped beginning in 1958 with Mk 43 homing torpedoes in an effort to increase the distance between the ships and their targets. The Mk 43 torpedo had a range of at .
