俄罗斯将用其雷达和导弹把印度空军的125～150架第二代的米格-21-93战斗机改装为第四代战术飞机,预计费用为4000万美元.这些米格-21将装头盔瞄准具和“标枪”雷达.“标枪”为X波段的多功能、多目标探测脉冲多普勒雷达,重3O1千克,采用50厘米的平板裂缝天线,能探测24个目标,跟踪8个目标,并能对4个最优先的目标进行自动扫描管理.改进后的米格-21将装备2枚R-27R1半主动雷达制导或4枚RVV-AE主动雷达制导空空导弹.另一种挂载方案是4枚R-73E短程红外空空导弹或6枚R-60空空导弹.它还能挂载反辐射导弹、反舰导弹、电视制导炸弹和火箭吊舱.驾驶舱将安装
Russia will use its radar and missiles to convert 125 to 150 second generation MiG-21-93 fighters of the Indian Air Force into fourth-generation tactical aircraft at an estimated cost of 40 million U.S. dollars. These MiG-21s will aim at the helmet With Javelin Radar, the Javelin is a multi-functional, multi-target, pulsed Doppler radar for X-band applications weighing 3lO kg using a 50-cm flat-panel slot antenna that can detect 24 targets and track eight targets. Automatic scanning management of the four highest priority targets.The modified MiG-21 will be equipped with two R-27R1 semi-active radar guidance or four RVV-AE active radar-guided air-to-air missiles.Another mounting scheme is 4 R-73E short-range infrared air-to-air missiles or 6 R-60 air-to-air missiles. It can also mount anti-radiation missiles, anti-ship missiles, TV- guided bombs and rocket pods.
