NovaScotiaBoy has beaten me to it. The helicopter appears to be some form of Sea Hawk, judging from the horizontal stabilizer & the position of what I think is the tail-wheel. The Korean Navy has no Sea Hawks, just Blackhawks (UH-60P); they were considering the Romeo a few years ago, but bought AW159 Wildcats instead.
The boxes 40degS is referring to are the ones outboard & slightly forward of the crane, and at the forward end of the amidships TEU block. In the original graphics, they are open-topped & covered by tarpaulins (not as obvious on the model). I don't think they are 'bi-cons'. I assumed they were stowage areas for the equipment associated with the crane (ie a frame to help with lifting containers, plus strops, lines, slings, cargo nets, maybe spare pallets, perhaps hoses if they intend to use the crane as a refuelling rig). The boxes are all within easy reach of the crane. Perhaps they hold bulky items like fenders - but like 40degS, I'm just guessing. I doubt they contain boats or life-rafts.
Other changes noticed in the model:
- The sides of the elevated walkway are now enclosed. This perhaps creates an ice-free access-way fore-and-aft on the deck under the walkway.
- The winches for the RAS system have been moved a deck lower. Again, I expect this is to do with ice-protection.
- The elevated TEU deck (meccano deck) has been extended out to the sides of the ship.
- the forward TEUs now seem to run fore-and-aft lengthways. Previously they were athwartships
There are probably others. Anyone?
