OK bro, I apologize for misunderstanding you. I have to be hawkish since some Indian posters are just as hawkish, I reckon you are a reasonable dude. Let call it even?
Accepted. No further issue.
'People' 'often' refer to a single large ship as a 'white elephant', a possession which its owner cannot dispose of and whose cost, particularly that of maintenance, is out of proportion to its usefulness. I can see how that would apply to a smaller navy that acquires a single major unit e.g. Thailand with its mini-carrier, but it could also be PN with a single 055.
Clearly, this does not necessarily reflect poorly on the qualities of the ship in question. More likely is that that navy cannot properly support that main vessel operationally with other ships, without ending with no ships available for other duties than carrier escort. So, effectiveness of the
fleet is reduced, the cost aspect of operating and maintaining the major vessel aside.
This is clearly not the case with 055 for PLAN, as more than a couple are apparently planned, and this is in line with addition of carriers, smaller destroyers and frigates as well as AOEs.
As for a large ship like 055 automatically being better than a smaller ship, remains to be seen. A larger ship means usually that more ordnance is carried and/or that the variety of ordnance is increased. Also, more or more powerful sensors. This together translated to greater stayingpower and/or ability to deal with more complex situations.
However, to the detraction of this may be that weapons, sensors - while effective - are possibly not as small as they could be. So, older Soviet ships tended to be larger then their US counterparts, because their main systems were bulkier, for a given capability. If able to miniturize and integrate functions and systems better, one may end up with an equally capable yet smaller ship.
In sum, one has to be very carefull with generalizations and look at the specifics of designs before making sweeping statements or judgements. I have no doubt both P15A and 055 are capable ships IN RELATION TO WHAT THEY ARE EXPECTED TO BE ABLE TO DO BY DESIGN (i.e. a relative not an absolute measure). That doesn't mean they are equivalent or identical. Or that they need to be.
