Oh, caught you by surprise didn't I?
This is the Stogiy-class corvette, a small yet radical-looking stealthy Russian warship that made its first appearance in the 2011 IMDS exposition, as seen here from the gallery of awesome Russian blogger Vitaly Kuzmin[link]
It's a catamaran with a pretty large flight deck, armed with an automatic gun located in a stealthy emplacement ahead of the command center that splits open to reveal the gun; it's also armed with a whole lot of tubes for the Klub/Kalibr series of missiles and a Palash combined missile/dual-gun CIWS.
Drew it because it's so eye-searingly ugly I can't help but find it charming. It's like the AN-94 or the Su-25.
