I am trying to figure out why the first batches of PLAAF JJ-7 have a c/n with a 'A' (like A0718) and later batches have a c/n with a 'L' (like L1508).
But I recently found PLAAF JJ-7 with c/n A0607 and PLAAF JJ-7 with c/n L0607.
Could JJ-7 A0607 had a MLU (i.e. re-equipped with J-7E or J-7G systems?) and assigned the new suffix 'L'?
Wow ... you always learn something each day.
Even if by all i know early JJ-7 batches are called JJ-7 and later ones JJ-7A - as standard by the Chinese nomenclature - I never noticed this.
