Project Sabre II was a Pakistan Air Force programme, begun in 1987, to create a low-cost multirole combat jet by radically upgrading the Chengdu F-7M, the Chinese version of the MiG-21 that the air force already flew. The air force hired the American firm Grumman to assess the idea together with Pakistani specialists and the Chinese Chengdu Aircraft Corporation. The concept replaced the nose intake with a solid radome housing radar and avionics drawn from the Northrop F-20 Tigershark, moved the air intakes to the sides of the fuselage and swapped the Chinese turbojet for a modern turbofan, either the General Electric F404 or the Pratt and Whitney PW1120. It was meant to replace around 150 Shenyang F-6 fighters in service. The air force ended the project as unfeasible on economic grounds, and American sanctions after 1989 removed Grumman. Its ideas passed to the Super 7 effort and, from 1995, to the JF-17 Thunder, which was introduced in 2003.
