讲讲枭龙Block 1和Block2吧。

    JF-17 Block 1 – Production in China began in June 2006.[116] The first eight Small Batch Production (SBP) aircraft, using the second prototype configuration, were produced in China and delivered to the PAF's JF-17 Test & Evaluation Flight from March 2007[117] to early 2008. A contract between the PAF and CATIC for 42 serial production aircraft was signed in March 2009.[118] The first three Chinese weapons to be integrated are the PL-5E II AAM, SD-10 AAM and C-802K anti-shipping missile. PL-5E II integration was completed in mid 2010. The last Block 1 aircraft, with 58% of its parts produced in Pakistan, will be completed by June 2012.[119] The Block 1 avionics package has been stated to be a positive surprise to the PAF, performing "better than expected" according to Air Commodore Junaid.[120]

    JF-17 Block 2 – Ordered by the PAF in 2011, includes "enhanced features".[120] Believed to be fitted with a Chinese AESA radar, Infra-red search and track (IRST) system and improved electronic counter-measures (ECM) suite. Also believed to incorporate greater use of composite materials for reducing airframe weight and possibly a thrust vector control (TVC) engine.[76]

对于BLOCK 2的重点就是：使用有源相控阵雷达,红外搜索系统，增强ECM（电子反击措施）。并且使用更多复合材料减轻机体重量。并且可能会使用TVC。

Block 2的合同是2011年，也就是今年签署的。虽然说发财在性能上不是一流的，但是承蒙巴铁厚爱，得以发扬光大，对于我国航空事业发展以及小钱钱有着重大深远的影响：）
