The Mark 39 (XXXIX), also known by it's name as "Starboost", is a Sub-Orbital suit and was one of the many newly built suits created by Tony Stark, sometime after the events of The Avengers.[1]

It was featured in the movie Iron Man 3, and makes it's debut in the movie when Tony ordered J.A.R.V.I.S. to initiate the "House Party Protocol" in which it was activated along with all the other suits to aid him in his fight against Aldrich Killian.

The suit earned it's name the "Starboost", for having the ability to travel into sub-orbital ranges and for venturing into space, as it is derived from it's name. It was built with an armor that could stand the cold temperature and radiation in space and was built in with an oxygen tank to allow Tony to be able to breathe while he was in space.

Tony's motive for creating this suit can be seen at the end of The Avengers. As Tony goes through the portal with the atomic bomb that would destroy Manhattan, his suit powers off. Stark then falls through the portal and is saved by the Hulk.

Armor DesignEdit

The Mark 39 has a white, black and silver color scheme designed to suit space travel. The suit is made of a special alloy that absorbs Tony's arc reactor signal. Attached to the back are removable secondary thrusters to get through the atmosphere.

It also has a unique Arc Reactor design, with three lines from each corner of the triangular reactor joining together in the middle. Additionally, the gold coloring of the face mask extends futher up the forehead than most armors, implying a larger field of vision equivalent to astronaut helmets.

Armor CapabilitiesEdit

Extreme FlightEdit

The Mark 39 has the unique and special ability to fly at extremely high altitudes, and even reach into space. The armor is advanced enough to go out into the sub-orbit of Earth and the very vacuum of space itself.

Iron Man 3Edit

The Mark 39 was activated by J.A.R.V.I.S. along with all the other armors in the basement of Tony's Malibu Mansion, after Tony gave the order of the "House Party Protocol". It then flew towards the the Roxxon Oil Rig, together with all the other 35 armors.

When the Iron Legion arrived, the Mark 39 was one of the first seven armors to appear on the scene, together with the Mark 17, Mark 35, Mark 15, Mark 33, Mark 40 and Mark 28. It surrounded the rig, along with all the other armors and waited for Tony's orders through J.A.R.V.I.S. As Tony finished up, he told J.A.R.V.I.S. to "Target Extremis heat signatures. Disable with extreme prejudice." The Mark 39 then started targeting and attacking the Extremis Soldiers after. It fought off the soldiers during the battle with the help of the other armors.

During the middle of the battle, when Tony was ordering J.A.R.V.I.S. to give him an armor to use, the Mark 39 could be seen flying to a crate and deflecting a metal pole that was thrown at it. Right after, the Mark 22 was destroyed by another metal pole that was thrown at it, just as Tony was about to jump into the armor.

The Mark 39 then continued battling the Extremis Soldiers in the rig along with the help of the other armors.It was seen again when a pole was thrown at it. It dodged the pole firing a repulsor blast, knocking over a extremis soldier causing their body to break a cable moving the shipping container Pepper Potts was held in. It is unknown what happened to it, as it may have been destroyed in battle or blown up by Tony's order of the "Clean Slate Protocol" as his devotion to his girlfriend Pepper Potts.
