Coal bunkers are used as extra armour; oil sprayers are used for extra speed or to raise steam quickly.

Includes one collapsible crane, floatplane hangar(1) and two floatplanes(one in the hangar, one on deck), and a catapult built into the deck forwards.

Armament -
28cm/50 SK L/50
10.5cm/45 FlaK 45
Becker M2 2cm Flakvierling

The aft 10.5cm triple superfires over the 28cm turret, which is mounted on the lower aft deck.

Forward torpedo tubes are fixed, 2m below waterline in the outermost compartment, and have no provision for reloads, minimising the downsides of having torpedoes on a warship.

The forwards armament is a bit anemic, but she's not designed to chase anything bigger than herself, and the 10.5cm guns are long ranged for their calibre.

Tiger is definitely designed this to take on the Izumo and win.
