J-8II Batch 02 (J-8IIB) : First flew in November 1989, improved J-8II with SL-8A (Type 208?) PD radar (70 km range). Powered by 2 x WP-13AII turbojet engines. Armed with twin-barrel 23mm Type 23-III cannon (copy of GSh-23L) and up to 4 PL-5 or PL-8 AAMs (or rockets/bombs). No BVR capability. Peace Pearl J-8 (J-8II) : During the Sino-US cooperation era, up to 50 J-8IIs were to be delivered to the US for upgrades and installation of AN/APG-66(v) radar and fire control system for US$500 million, under the Peace Pearl program. However, the project was canceled and onl y about 24 J-8II was produced.[3] J-8IIACT (J-8II-BW2) : First flew in 1988, fly-by-wire testbed and technology demonstrator

Improved all-weather version with SL-7A fire-control radar (40 km range), twin-barrel Type 23-III 23 mm cannon, & up to 4 AAMs (or rockets/bombs). Limited production. J-8E : Mid-life upgrade for J-8I. JZ-8 (J-8R) : Reconnaissance version of J-8 or J-8I. J-8ACT : First flew on 24 June 1990, fly-by-wire testbed aircraft. 2. J-8II (Finback-B) Series J-8II (Finback-B) : First flew on 12 June 1984. Improved J-8I prototype with redesigned nose/front section and fuselage. Replaced nose air inlet with solid nose and lateral air intakes, similar to those of the MiG-23 China indeed received several MiG-23s in the late 1970s from Egypt and the hinged ventral fin and lateral intakes shown reversed engineering of these MiG-23 features into the J-8II, in fact China followed a very similar development process to the Su-15 when from the Sukhoi T-5, the large T-58 (Su-15) was spawned, the MiG-23PD also has some similarities with the J-8II however the MiG-23PD is a single engined experimental fighter with direct lift engines, but the transformation of the MiG-21 into the MiG-23PD was mirrored in the J-8II. Equipped with Type 208 (SL-4A) monopulse radar (40 km range). J-8IID (J-8D) : First flew on 21 November 1990, modified J-8B with fixed refuelling probe and updated avionics such as TACAN navigation system. F-8IIM : Unveiled in Zhuhai Air Show 1996, export version of J-8B with Russian Phazotron Zhuk-8II PD radar (70 km range), R-27R1 (AA-10) AAM and Kh-31P anti-radiation missile. This aircraft is often mistakenly referred to as the "J-8IIM" with Kh-31A anti-ship missile (ASM) capability, but its radar lacked sea search mode for anti-shipping role. Failed to attract any export customers and no domestic orders. [4] Conversion from older airframe was reportedly much fewer than the 100 units of Zhuk-8II radar delivered, and the conversion might have onl y been an experimental program
J-8III (J-8C) : Upgraded J-8II with FBW system and 2 x WP-14 powerplants. Compared to the J-8II, the J-8C had a number of improvements including a new multi-mode pulse Doppler radar which was reportedly based on the Israeli Elta EL/M 2035 radar technology. The aircraft was also equipped with a digital fire-control system and a new ‘glass’ cockpit with multifunctional displays (MFD). The J-8C programme entered full scale development around 1991 and the aircraft first flew successfully in 1993. Development halted in favor of other version described below, but was used to test new radars such as Type 1471 (KLJ-1) and other avionics associated with FBW system. From this version on, electronic warfare pods such as BM/KG300G and KZ900, as well as navigational / targeting pods including Blue Sky navigation pod and FILAT become operational on J-8II. J-8IIH (J-8H) : First flew in December 1998, upgraded J-8II with new glass cockpit, WP-13B power plant, Type 1471 (KLJ-1) PD radar (75 km range) with look-down, shoot-down capability. Can use medium-range R-27 (AA-10), PL-11 AAMs, and YJ-91 anti-radiation ASMs. J-8IIF (J-8F) : First flew in 2000, J-8H with WP-13BII powerplant, in-flight refueling probe, and Type 1492 PD radar. Successfully test-fired PL-12/SD-10 AAM in 2004. J-8IIM (2006) : At Zhuhai Air Show 2006, a new variant "J-8IIM" was put on display with upgraded systems similar to the J-8H. The most significant improvement is the radar upgrade with a new Type 1471 domestic radar used by the J-8H. In comparison to F-8IIM's Russian Zhuk-8II radar, the Type 1471 radar has a number of performance enhancements
Type 1471 radar has 75 km maximum range for targets with 3 square meters RCS, in comparison to Zhuk-8II's 70 km maximum range against target of 5 square meters RCS.
Additional ability to handle sea-borne target that Zhuk-8II does not have. For sea targets with 50 square meters RCS, the max range is greater than 100/80 km for sea state 1/2.
Simultaneously tracking 10 targets and display 8 most threatening one s out of the 10 on displays, engaging 2 out the 8.
Air-to-Air modes: VS (Velocity Search), RWS (Recon./Search while Scan), TWS (Track While Scan), STT (Single Target Tracking), Air Combat Mode (ACM). AMTI, (aerial moving target indication) mode which is used to discover hovering helicopters can be added upon customer request, though this does not come as standard feature.
Air-to-Ground modes: Mapping (Real Beam Mapping RBM), Mapping Expansion/Freezing (EXP/FRZ), Doppler Beam Sharpening (DBS), Ground Moving Target Indication (GMTI), Sea Single Target Tracking (SSTT), Air-to-Ground Ranging (AGR).
An improved beacon navigation (BCN) and weather (WX) capability.
