The Iroquois- class , also known as the Tribal class , was a class of four destroyers in the Royal Canadian Navy . They were put into service in the 1970s, initially with submarine hunting as their main task. In the 1990s, the destroyers were completely overhauled and also expanded for extensive air defense . On March 10, 2017, the HMCS Athabaskan was the last unit of this class to be decommissioned by the Royal Canadian Navy.

Original concept

The ships were designed as long-range destroyers. The range is approx. 8300 km. The Iroquois class represented a new development in the history of the Canadian Navy. There is enough space on the flight deck for two CH-124 Sea King helicopters. The larger flight deck made it possible to maintain the helicopters better than in the past. For underwater battles the helicopters supported the destroyer, each of which was equipped with two triple torpedo tubes for Mk.44 and Mk.46 Mod. 5 torpedoes . They also had Limbo Mark 10 depth charges and a fully automatic 127/54 Compact ship gun. An eight - fold launcher for RIM-7 Sea Sparrow , a radar-controlled air defense system, was available for air defense.

Modifications in the Gulf War

The HMCS Athabaskan (DDG 282) was deployed to support the international coalition in Operation Desert Shield and Operation Desert Storm . She was the flagship of the Canadian Naval Task Group and was quickly modified for the new tasks. The modifications took place in the CFB Halifax in 1990 and included the installation of a mine avoidance sonar , a Phalanx CIWS above the Limbo Mk.10 depth charge launcher and the equipment with portable anti-aircraft guided missiles of the Blowpipe and Javelin types . The modifications made the depth charge thrower no longer usable.
