Eventually, the Pakistan Navy began its wartime deployment in Middle Eastern countries through the Persian Gulf and deployed its war assets in Saudi Arabia in support of the U.S. Navy's fleet in wake of the events involving the Iran–Iraq War and tensions with Libya. In 1982, the Reagan administration approved US$3.2 billion military and economic aid to Pakistan with Pakistan acquiring eight and frigates from the United States Navy on a five-year lease in 1988. A depot for repairs, followed the lease of these ships in April 1989. This was done due to the Zia administration's co-operation with the Reagan administration against the Soviet Union's invasion in Afghanistan.
