On 2 March 2007, the first consignment of two small-batch-production (SBP) aircraft arrived in a dismantled state in Pakistan. They flew for the first time on 10 March 2007 and took part in a public aerial demonstration during a Pakistan Day parade on 23 March 2007. The PAF intended to induct 200 JF-17 by 2015 to replace all its Chengdu F-7, Nanchang A-5, and Dassault Mirage III/5 aircraft. In preparation for the in-flight refuelling of JF-17s, the PAF has upgraded several Mirage IIIs with IFR probes for training purposes. A dual-seat, combat-capable trainer was originally scheduled to begin flight testing in 2006; in 2009 Pakistan reportedly decided to develop the training model into a specialised attack variant.
