The Pakistan Navy will receive the refurbished USS McInerney frigate on 31 August under a $65m contract.
Pakistan will induct the Perry Class guided missile frigate into the country's naval fleet as PNS Alamgir.
The vessel will be handed over to Pakistan following the completion of a refurbishment which includes anti-submarine capability in January 2011.
Pakistan also plans to increase a squadron of eight Perry Class frigates.
The 132m-long and 14.32m-wide frigate has a displacement capacity of 4,100t, accommodation for 212 crew and a top cruising speed in excess of 28kt.
