Halifax-class Multirole Patrol Frigate

The Halifax-class Multirole Patrol Frigate is a class of warship in service in the Canadian Forces Maritime Command from 1991 onwards. The Halifax-class replaced the Restigouche, Mackenzie, and Annapolis class destroyer escorts. In late 2011, the Ministry of Defense authorized an extensive upgrade for the Halifax-class frigates to improve their capabilities.

The design of the Halifax-class frigates reflected many advances in ship construction, such as a move to a prefabricated unit construction method, where the ship is assembled from prefabricated units in a dry-dock instead of the traditional keel-laying. Furthermore, the design of Halifax-class frigates incorporated many new technical improvements. For example, these vessels were the first in the world to be equipped with the Integrated Machinery Control System (IMCS), which allows for a very high degree of computer control for the machinery plant.
