The Tariq-class destroyers are a class of guided missile destroyers of the Pakistan Navy. They were acquired from the British Royal Navy in 1993–94. The Tariqs were formerly commissioned in the Royal Navy's Surface Fleet as Type 21 (Amazon-class) frigates, a general purpose frigate in the Royal Navy. The British frigates were immediately acquired when the United States refused to renew the lease of the four Garcia and four Brooke-class frigates, due to the enforcement of the Pressler Amendment. requiring Pakistan to return the vessels to the United States at the end of their five-year lease.
