- Steelhaven is a starship from the Marvel Comics portion of the Generation 1 continuity family.

Fortress Maximus grew tired of the never-ending war on Cybertron and planned to escape it. He and other Autobots who shared in his vision of peace built the Steelhaven, a lance-shaped Autobot starship. Its destination was Nebulos, a peaceful planet which was home to small, human-like organic creatures.

Marvel Comics continuity

When the Autobots neared Nebulos, they parked it in orbit and descended to the surface under their own power. Ring of Hate! However, the Autobots were followed by Scorponok and his Decepticon crew, and when the Decepticons joined the Autobots on Nebulos, a war broke out that culminated in the creation of Headmaster and Targetmaster technology. To spare Nebulos from further war, both sides fled to Earth. Brothers in Armor!! The Steelhaven remained in orbit there and served as that group of Autobots' base of operation for some time.
The ship had limited resources, and a chunk of it was used during transit to Earth for rebuilding Fortress Maximus to be bigger and more powerful. Trial by Fire! Even more resources were used to repair Fortress Maximus after his defeat at the hands of Shockwave, The Desert Island of Space! a new body for Goldbug, and creating Pretender technology. Pretender to the Throne! But by the time they needed to build a new body for Optimus Prime, the remaining resources on board the Steelhaven were insufficient.

Soon, the Steelhaven was introduced to the other Earth-bound Autobot ship, the Ark. A battle for Autobot supremacy followed, and both ships landed on Earth's Moon so that both sides could disembark and view the battle. Fortress Maximus saw this as frivolous, and so while everyone was distracted, he ordered Goldbug to take the Steelhaven and its skeleton crew back to Nebulos to build a new body for Optimus Prime. Totaled! The Steelhaven remained parked above Nebulos once again, while Optimus Prime and Goldbug's crew were rebuilt as Powermasters. People Power! On the way back to Earth, the Steelhaven intercepted a commercial from the Cosmic Carnival, and when it revealed that Sky Lynx was one of its stars, Optimus Prime and Goldbug investigated. The Cosmic Carnival!
