This is the AA 1/200 scale model of the Chinese PLAN Type 051 Luda-class destroyer Kai Feng.
I won this kit in a raffle in 2006 and don't know very much about it. Neither does my cat. 
I've never heard of "AA" models in any other context. 
The kit quality was not high; fit was terrible, lots of seams, sink marks, and flash, and most of the kit pieces were not well-detailed. I did my best to dress it up with bits of styrene and wire, and I added scuttles with small brass rings. I determined early on that it wasn't worth investing in a PE set for this one, so I used the styrene railings included with the kit. In 1/200, they're actually not too bad.
