Onslaught attack ships are the mainstay of the Ork escort squadrons, being solid and well armed vessels for their size. The Onslaught's gun batteries are exceedingly powerful (if unreliable) but have a limited fire arc and their prow is heavily armoured giving them a good chance of surviving a head on attack.
The Onslaught Attack ship is ugly, difficult to maneuver, and lightly armored along its flanks and rear. It is only suitable for head-on attacks. However, as discovered by Admiral Sartus aboard the doomed Laertes, a swarm of Onslaughts can lay down a fearsome hail of fire from their multiple forward gun batteries. This is combined with thick frontal armor and shielding to protect them during their initial attack run.
Like all Ork attack ships, Onslaughts are capable of landing on planets as part of an invasion force and can carry a large Ork warband plus their vehicles and artillery.
