Ork Assault Boat
The Orky version of the Imperium's Shark Assault Boat. They resemble a bit like the Dreadclaw Assault Pod but more Orky and a tad bit bigger.
Orks make use of assault boats for boarding actions during space battles. More or less equivalent to other races' counterparts, they basically are an Ork-filled armoured shell with a piercing beak at one end and a great big engine at the other. Resembling Boarding Torpedoes almost as much as they do Attack Craft, these machines are quite effective at delivering their deadly cargo to a target despite their simplistic nature.
Battlefleet Gothic Armada 1 & 2
In Battlefleet Gothic Armada, Ork Assault Boats behave the same as the other factions' assault boats, with the only difference being an aesthetic change.
