If China are serious about operating a modern blue water fleet then it seems to me the construction is going a little slow.By the time these 054's are built (assuming A.man is correct) everything from the early Jiangwei II back, will be up for decomissioning or resale at least, as they will be more than 20 years in service.That leaves around 30 frigates,a drop of around 20 on current numbers( give or take a few).So building 18 054's is unsurprising in the sense that the PLAN seems very satisfied with this design, but still it is not enough.I think they need more ,whether they be 054's or a brand new successor.I'm basing my argument on China looking to emulate or get close to ,say the UK in terms of service life for their frigates.(15 years approx + SLEP. i think).This seems a serious headache for the PLAN actually,a big ask even for their quick construction times.Am i missing something ?
