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.

It was later engineered by remnants of the U.S. military after the Great War. It improves upon older suits by offering superior protective abilities

Characteristics
X-01 power armor provides the greatest defense among all models of power armor featured in Fallout 4. The power armor bears resemblance to an advanced power armor seen in previous Fallout games. Similar to the T-60, it appears to have a large blind spot (mainly due to the large shoulder plates) around the arms and back as they rise over the helmet. This is ironic as for a top-of-the-line combat armor it would be a great tactical disadvantage.
