Guys,
Need your professional opinion.
Need your best estimate of PLAN's fleet circa 2020. Include all major and minor vessels if possible.
In service by 2020, my guess:
Corvettes:
~60 056/As
Frigates:
>24 054As (possibly 30+ 054As, but it's also possible some of those will be 054Bs)
2 054s
Some number of older 053H3s still in service as well
DDGs (aegis-type):
2-3 055s (with more in sea trial/fitting out/launched/under construction at that time as well)
>12 052Ds (probably more, maybe up to 18)
6 052Cs
DDGs (non aegis-type):
4 Sovs
2 051Cs
1 051B
2 052Bs
2 052s
(all 051s likely to be retired by 2020)
other ships like 022 FACs will probably still be in service as well... and there are of course non surface combatants that aren't listed.
edit: I also wrote a more detailed entry about this very topic a few months back on my website
