Bringing death and total destruction from the depths of the ocean, the "Merlin II" Nuclear Submarine is more than capable of leveling armies, cities or both. In it's offensive capabilities, it contains 9 Tactical Nuclear Missiles, 12 Torpedoes, and 14 Sea-to-Ground Attack Missiles. When surfaced it can keep up the attack with STS Cannons and AA Cannons. In a defensive role, it can jam enemy radar and equipment with an ADJA. The rest of the general equipment are ACA, Double Screw Drive and AVD.
Equipment list: STS Cannons, ACA, AVD, Double Screw Drive, ADJA, AA Cannons, Torpedoes, SGAMs and TNMs.

I suggest drawing the guns a bit more detailed, not just "thick lines" like that, especially the turrets : a little extra details make a lot differences to them.
Other than that, it looks cool :D
