Korean look good but expensive.
as many state that this is not good war equipment, I state that this is one of the very good equipment for attacking land and sea target.
when Iran want to overwhelmed usa advance navy, its need every thing in mass number.
like Ghadir Class submarine, like rocket launcher, and missile launcher, and torpeduo launcher, and mix of these types.
these Bavar-2 is assume it as very fast Ya Mahdi Missile Boat.
Bavar-2 is much better and advance with respect to rocket launcher
see below:


even these fast boat with such a basic rocket launcher
in mass target a ship, the ship going to get and suffer from quit firepower from all the site.
Iran indeed could make more advance and much better looking flying boat, but they need it to be as cheap as possible and as fast as possible to produced.
and that is what Bavar-2 is look like.
I see a great advantage in the Bavar-2 compare to any other Fast
Iran already have: [faster 185km/h, more stealth, have the ability to use missiles, law altitude flying, very cheap and fast to produce]
