		The Iroqouis (Tribal) class, though not originally fitted with any major offensive or defensive missile armament, was successful by nature of the vessels' size, advanced sensors, and large helicopter.
		Between 1989 and 1992 the ships were given the TRUMP (TRibal Update and Modernisation Project) upgrade. This consisted of replacing the main gun and Sea Sparrow with a Mk41 VLS and 76mm Super Rapid. In addition, various sensors were also upgraded, turning these ships into quite self-supporting destroyers.
