Iron Will

The Iron Will is a spacecraft from the Prime cartoon portion of the Aligned continuity family.

If you squint, it could still be the Steelhaven.

As Optimus Prime's lieutenant, Ultra Magnus needs a spaceship capable of withstanding the rigors of war. The Iron Will possesses great maneuverability thanks to its variable geometry, and is both well armored and well armed. Though small, it's roomy enough to accommodate a modest force of Autobots and has a formidable arsenal of weapons both large and small.

Fiction

Prime cartoon

Ultra Magnus traced a huge energy surge to Earth, landing his ship in front of Arcee and Jack Darby. Searching for Bulkhead and Wheeljack led Magnus to take the ship into battle against the Predacon which the Decepticons had unleashed. It shrugged off the hits from the ship's main guns and grabbed on to the top of it. Magnus attempted to shake it off, and eventually managed to dislodge the beast by flying the ship close to the sides of a canyon. He set the ship down near the Harbinger, to rendezvous with the Autobots sheltering there. Prey

He utilized the ship during the battle against Darkmount, managing to trick the Predacon into going through a GroundBridge. When the stealth team failed to penetrate the fortress, he set the ship's autopilot and went in himself, later using the ship as a getaway vessel once Optimus Prime turned up and took out the base's defenses.

The ship was useful transport for getting Ultra Magnus, Bulkhead, and Wheeljack to Scotland. It was also explored by Starscream and two members of his Seeker armada, but surprisingly wasn't disarmed, disabled or confiscated by the devious Air Commander. Chain of Command Wheeljack later recalibrated the engines to get more thrust. Evolution

Optimus Prime and Wheeljack took the ship to Theta Scorpii to retrieve the AllSpark. Though they succeeded, the ship was damaged, disabling the transmitter, and thus they couldn't respond when the Autobots back on Cybertron sent a warning that Unicron was back. On their return to Cybertron, Unicron damaged the ship further, causing it to crash. Predacons Rising
