these days, the kanwa article are normally piece of junk, but this article on the PGMs displayed in zhuhai is quite informative if it actually is true.
Let's see if I can translate the gist of this article.
says that it uses electronically controlled tail fin, glide wings use composite materials
bomb diameter is 377 mm
wingspan is 2740 mm
weight is 540 kg
warhead is 440 kg
release point at 8000 m, release velocity 250 m/s, range is 48 km.
release at 11000 m, range is 60 km.
It mentions of two tests, one test was carried out at 65 km range and was off target by 7.5 m and the second test was carried out at 75 km range and was off target by 5.3 m. So, falls well under the spec of 15 m CEP.
outside of LS-6, there is another classified bomb in the LS series under development using GPS/INS guidance with motor and has a range of over 200 km.
also, plaaf has already started to equip LS-6 with JH-7A, but it has yet to enter mass production. currently, it does not have a 2000 kg satellite guided bomb, because it simply doesn't have any 2000 kg dumb bomb. The current plan is to refit the existing dumb bombs.
also, can use a combination of 2 GLONASS satellites + 3 Beidou satellites to find positioning for LS-6.
another revealed PGM is LT-2, which has a CEP of 3 to 5 m, passive laser guidance of 20 s?, LT-2 laser seeker has a range of 4 km, the view is +/- 12.5 in one direction and +/-1 20 degree?
Also on FT series, shown FT-1 and FT-3 in Zhuhai as we know.
FT-2 is a glide bomb unlike the other two and has a range of 60 km.
FT-4 is a 100 kg SGB.
FT-5 is even smaller, probably for UAV.
can be fit on the bomb wracks of JH-7A and Q-5G
For FT-1/3, the test results achieved CEP of 20 m with JH-7A, but the specs are still 30 m, dropped from 5000 to 12000 m, drop speed mach 0.6-0.9, FT-1 is 500 kg, FT-3 is 250 kg, range is 18 km.
Carried out numerous tests, some failures, but mostly showing satisfactory performance.
