They had pretty much all the attributes you don't want in a point defense system, which limited the Iroquois class' air defense capabilities.
Raytheon's RIM-7 Sea Sparrow surface-to-air missile—which was directly adapted from the AIM-7 Sparrow air-to-air missile—quickly became a huge success, serving with the U.S. Navy and many allied armadas after first entering into service 45 years ago. One NATO ally, in particular, fitted a class of surface combatants with a Sea Sparrow launcher system that was laughably bizarre and supposedly remarkably ineffective. Those ships were Canada's Iroquois class destroyers, also known as the Tribal class.
The Sea Sparrow system has evolved drastically in terms of capability and form over the decades. You can read all about its earlier and more basic version in this past article of ours. Now in its RIM-162 Evolved Sea Sparrow Missile Block II form, it still enjoys great success. The RIM-7 was designed as a fast-reaction point defense system used to swat down incoming anti-ship missiles and aircraft, some of which could pop-up with little notice as they skim low and fast over the water.
