Info:
http://www.diecastaircraftforum.com/modeldatabase/detailview-16502.htmlChina was receiving aircraft and technical help from the USSR. When Egypt and China
seemed to be looking to the US for assistance, relations with the USSR ended. To keep
aircraft development going in China, Egypt sent a Mig-21MF in return for a Romeo Class
SSK sub. China reverse engineered the Mig-21MF and developed the J-7C/D. Externally
the J-7D was almost identical but had some improved avionics and weapons controls,
many J-7Ds were just upgraded J-7Cs. This J-7D originally was an operational night
fighter under the Beijing MR (Military Region) at Huairen Air Field.
Aircraft 30168 was originally assigned to the 10th Air Corps, 15th Air Division, 43rd
Regiment, 1st squadron had 15 J-7Cs used as spares and 2nd squadron had 10 J-7Cs
operational. 3rd squadron had 10 J-7Ds operational and 4th squadron had 10 J-7Ds
operational as a night fighter under the Beijing MR (Military Region) at Huairen Air Field.
There were a total of 6 Regiments 4 night fighters and 4 training regiments with 10
aircraft. All the J-7Ds were modified versions of the J-7C and were given a new light grey
paint scheme for the night fighting role.
Trying to improve the shortcomings of the J-7C a more powerful WP-13F1 turbojet
(7,300kg w/ afterburning) was installed to improve the maneuverability. Avionics were
upgraded as well, which include more reliable JL-7A J-band fire-control radar, HK-13A
HUD and fire-control computer, JD-3II TACAN, 563B INS, and RKL-800 integrated ECM
system, 941-4A chaff/flare dispenser. J-7D can be distinguished by a new set of 930-4
RWR antennas on top of the vertical tail-fin. The aircraft also features an improved weapon
management system for the new PL-8 IR homing AAMs.
