turbofan engine, FBW flight controls, day/night precision surface attack capability, and multi-mode, pulse-Doppler radar for BVR air-to-air attack capability. The sixth prototype, PT-06, made its maiden flight on 10 September 2006. Following a competition in 2008, Martin-Baker was selected over a Chinese firm for the supply of fifty PK16LE ejection seats. Production 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. In November 2007, the PAF and PAC conducted flight evaluations of aircraft fitted with a variant of the NRIET KLJ-10 radar developed by China's Nanjing Research Institute for Electronic Technology (NRIET), and the LETRI SD-10 active radar homing AAM. In 2005, PAC began manufacturing JF-17 components; production of sub-assemblies commenced on 22 January 2008. The PAF was to receive a further six pre-production aircraft in 2005, for a total of 8 out of an initial production run of 16 aircraft. Initial operating capability was to be achieved by the end of 2008. Final assembly of the JF-17 in Pakistan began on 30 June 2009; PAC expected to complete production of four to six aircraft that year. They planned to produce twelve aircraft in 2010 and fifteen to sixteen aircraft per year from 2011; this could increase to twenty-five aircraft per year. On 29 December 2015, PAC announced the rollout of the 16th JF-17 Thunder fighter manufactured in the calendar year 2015, taking total number of manufactured aircraft to more than 66. Later, a PAF spokesperson said that in light of the interest shown by various countries, it has been decided that production capacity of JF-17 Thunder at PAC Kamra will be expanded. Russia signed an agreement in August 2007 for re-export of 150 RD-93 engines from China to Pakistan for the JF-17. In 2008, the PAF reported it was not fully
