well I heard this type of midget subs can be deadly to aircraft carriers, right?
The Japs & the Nazi's both had small, suicide-subs. Think of this as an underwater version of what hit the USS Cole.
I'll take a stab at it. I took as good of a look as I can at it, and it seems like it is designed more for a littoral role ( coastal- near coastal) than a deep ocean role.
Visibly, it has a snorkel mast, radar, vhf or uhf radio antennae, and periscope. The sail looks to be kind of cheaply built, and the superstructure appears to be built over the pressure hull.
I couldnt figure out what the round barrel shaped assembly was that appears to be welded to the forward deck, but it looks a lot like a life raft cannister.
I cannot see any weapons systems visible, but that doesnt mean it doesnt have any. They may have the torpedos arranged external to the hull or carry them internally, depending on space. They may also have shoulder fired weapons for self defense stowed inside the vessel.
My bet would be on it being a copy of some type of a North Korean mini-submarine design. They probably will use it for personnel insertion/extraction, shipping attacks in coastal or near coastal waters, and intel gathering. I dont think it is useful or well designed enough to operate in the deep water arena
Looks like a tiny little toy diesel boat to me :)
One MK 48 will make mincemeat out of it :)
