Ork Assault Boat
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 in function 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. Pretty run off the mill and used best at close range.
