For the ASW version
Inthinkable to see depth charge in "air" storage aft, simply on fligth deck (extremely dangerous).
Even a only one north korean snipper, with a powerfull good rifle (maybe a 12,7mm long caliber rifle), can be destroy this entire ship by ignitiate aft depth charge
They are not permanent placed there , the depthcharges them selfs are stored inside the ship;)
or i could build an cover over it .
Visby Class Corvette armament:
1 × 57 Mk3
8 × RBS15 Mk2 AShM
Mines and depth charges
There is no Vertical Launched missile with a DC in it?
