Dwarves are arguable the technologically most advanced Man O’ War fleet. They use the equivalent of 19th century ironclad steamships and even manage submersibles! My fleet uses the same dark green and yellow scheme that I originally “invented” for my Mordheim Dwarf warband. The runes on the smokestacks are unique and tie each model to their ship card. Most of the ships also have other colour coding that is tied to their card (e.g. yellow rings on smoke stacks, etc.).
Man-o-War: The Dreadnought is the only official Dwarf Man-o-War class ship.
Independent: Even though they are independent ships, the Ironclads basically form the workhorse of the fleet.
The Nautilus submersible is another model that didn’t do so well in the “3 per set” packaging of Man O’ War. Worse, I ended up with two boxes somehow. I gave two models away but four submersibles is still three too many. Fifth model is a placeholder for dive runs.
Ship of the Line: Two squadrons of Monitors are the main formations of the fleet. While under-crewed and under-gunned (for Dwarves) , they are at least cheap enough to add mass.
Flyer: Gyrocopter and War Balloons are both iconic flyers for the Dwarf army in the Warhammer world.
