Currently the country's air force operates a fleet of US F-16s, French Mirage-5s, Chinese F-7s and Sino-Pakistani JF-17s.
Earlier, Moscow and Islamabad clinched a deal on the delivery of Mi-35M transport and attack helicopters to Pakistan, and the contract could be expanded.
While the media are discussing the PAK FA, F-35 and J-20, the fifth-generation aircraft being tested in Russia, the US and China respectively, the fully operational Su-35 seems even more reliable for the moment. It has been touted as "4++ generation using fifth-generation technology", rendering it superior to other fourth-generation fighters under development.
The Su-35, NATO reporting name Flanker-E, is a multirole fighter that is capable of engaging several air targets simultaneously.
