J-10B for economic

The J-10B differs from the original J-10A model in several ways: active electronically scanned array (AESA) radar, integrated jamming pods, IRST sensor, diverterless supersonic intake (DSI), and an uprated AL-31FN Series III turbofan engine. These upgrades give the J-10B increased engine power, infrared detection against stealthy aircraft and increased jamming capability against enemy missiles. In particular, the DSI has two advantages over traditional engine intakes: it saves weight and is more stealthy against radar. The most important upgrade in the J-10B is its AESA radar, which features a longer range, frequency hopping to foil enemy jamming and higher power to track stealth aircraft (such as the US B-2, F-22, and F-35) at long range. The J-10B also possesses a strong multirole capability– it can carry both 100km ranged PL-12 air to air missiles and LS-500J laser guided bombs on the same mission. These advanced “4.5+ generation” features places the J-10B in the same class as the F-16 Block 60 (flown only by the UAE), French Rafale, and Eurofighter Typhoon.
