The propelling machinery was of British design.The Ottawa is an anti-submarine frigate and was officially classed as a major warship; as such she was one of the first to be designed in Canada. Built mainly for the detection and destruction of modern fast submarines, she has a long range sonar and improved armament and electronic equipment. She was also designed so that in an emergency the class could be produced rapidly and in quantity.
Details of the ship are as follows: displacement 2,260 tons standard, 2,800 full load. Length 366 ft. beam 42 ft. draft 18.2 ft. She carries one antisubmarine helicopter. Original armament: four 3-in 50 cal. AA. guns (two twin); two 40 mm. AA. (single) and two "Limbo mortars".
