No, no, never, that would be far too war like
Ever since I first heard of the Hyuga I have been a fan of these ever improving ships and have thought them to be ideal for the RAN. Actually they are not dissimilar to the RNs aborted Escort Cruiser of the 1960s in concept, hence what the Invincibles were originally seen as.
There was a very good piece by a retired Japanese admiral explaining the origins of these ships. Basically during the 50s the reconstituted Japanese Navy the JMSDF determined that they needed hunter killer groups built around ASW carriers, CVS but were never able to obtain any so developed an alternative group intended to consist of a pair of DDHs and eight destroyers, two DDGs and six DDs. There were four groups but only ever four DDHs, now these groups have evolved to consist of a through deck DDH, an AEGIS DDG, one or two non AEGIS DDGs and five or six DDs. It was all about the number of helicopters required, one on each destroyer and the rest on the DDH, the larger ships permitting MCM helicopters and other specialist support types to be carried, as well as providing deeper level support for the destroyer ships flights.
