X-01 Power Armor

"The X-01 power armor. Lily ordered the X-01 power armor to be built, as ordered, while me and the Preschool Girls were fighting here... in Mambajao."

--Su Ji-Hoon, Mambajao

An X-01 power armor is a set of power armor that appeared from Fallout 4.

Background
The X-01 power armor is a set of power armor created shortly before the bombs fell.

A variant of the X-01 power armor was still in testing phases with the scientists at Nuka-World as a part of a cooperative initiative between the United States Armed Forces and Nuka-Cola Corporation when the bombs fell. This unique variant is known as the Quantum X-01 power armor, and can be found at Starport Nuka.
