The Ironclad Strela was an 1880's russian warship shaped like a cone. The idea was that it would be able to deflect cannon balls, resulting in a strong warship. However, she soon became obsolete when armor piercing rounds became more common.
HOW TO OPERATE:
Make sure all air valves on the fireboxes are under 55% to insure the boilers don't explode.
In battle, lower the smoke stacks using the levers on them, raise the cannons using the hand cranks, and fire away.
TO SINK:
Set the air valves to max and wait for the ship to explode!
