Islamabad (Reuters): Pakistan have signed a memorandum of understanding with Turkey for the sale of four Turkish-made corvette warships and 52 Pakistan-made training planes for Ankara's armed forces, Turkey 's defense industry undersecretariat said on Wednesday.

Karachi Shipyard (KS&EW) will buy four corvettes made under Turkey 's MILGEM warship program, aimed at designing and building locally a fleet of multipurpose corvettes and frigates that will replace older ships.

According to Turkish defense undersecretariat, the final deal was expected to be signed on June 30. The statement did not provide any financial details.

Turkey will buy 52 Super Mushshak training planes from Pakistan Aeronautical Complex - Kamra, to replace the T-41 and SF-260 planes currently in use, a statement by Ankara's defense undersecretariat said.

The statement added that this would be the first time a NATO country has used Super Mushshak planes.

Two warships built under the MILGEM project so far, named TCG Heybeliada and TCG Buyukada, were delivered to the Turkish navy in 2011 and 2013. Construction is ongoing for TCG Burgazada and TCG Kinaliada, which are expected to start active duty in 2018 and 2020, respectively.
