"Iran officially launched the production of the locally built submarine, claiming it was a stealth craft." LOL
they said stealth........lol, looks like a peice of crap that houses other peices of crap who drive it.
Most U.S Navy, and other nations ships, are painted 'haze grey' to make them less visible.
It seems that the Iranians missed this subtle difference and want their 'great' submarine to be seen.
