If it is true that all of the 056s are going to be transferred to the coast guard, there are a few different ways of evaluating this news and most of these angles have been covered by other posters. Obviously, how we evaluate this news in terms of PLAN strength, doctrine, etc. depends upon what else is coming down the pipe, i.e. more 056A, an 056B, a new 057 light frigate, or the new 054As. At first glance, it does seem rather wasteful and lacking in foresight to produce a significant number of modern, reasonably capable vessels, only to discard them (from a PLAN perspective) with less than a decade of service. But if we ask ourselves what kind of circumstances could reasonably produce a series of events like this one, we would probably conclude that it most likely to occur in a highly dynamic environment, i.e. an environment experiencing significant change. Change in budget, in the broader inventory, in technology, in strategy and doctrine, in institutional relationships. And we can see that this dynamism readily applies to PLAN today, and in largely a positive sense, i.e. the dynamism is in the direction of growth. That is to say, whatever the specifics turn out to be in this transfer of 056s from PLAN to CCG and their hypothetical replacements in the PLAN inventory, in a broader sense we can see these events as an artefact of PLAN's underlying dynamism, akin to an adolescent growth phase.
Come on. With PLAN expanding so fast, that shouldn't be the decisive factor here.
I disagree. Personnel are the foundation of the Navy as with any other institution. In the past PLAN could probably afford to be rather lax in terms of allocating people in ways that maximise efficiency, because wages were cheap compared to the capital required for large warships with high-technology systems. That is to say, PLAN's capabilities were constrained by lack of capital and technology, not by personnel. But just as the capital costs of large warships with high-technology systems are becoming less challenging for PLAN, the cost of personnel is becoming more challenging as wages rise. We can expect PLAN to be taking an ever-closer look at the "bang for buck" that it is getting from its people, and over time this will almost certainly drive PLAN to larger, more capable multirole platforms. I don't want to overstate this trend: PLAN is decades away from confronting the kinds of labour costs that shape inventory trends in e.g. European navies, but the trend is there and we can expect it to exert some influence on the inventory going forward. Ultimately, that is to say that I don't find it
implausible that PLAN may have decided to swap 20 056s for 20 054As. I'm not saying that is actually what is happening, but it does seem superficially plausible.
