Gundam NT-1(Chobam Armor equipped)

Model Number: RX-78NT-1FA

Designed for the Gundam NT-1, the Chobam (Ceramics Hybrid Outer-shelled Blow up Act-on Materials) armor is a series of optional armor plates attached to the machine's main body. It is a composite armor developed as part of the Full-Armor System and Weapon System (FSWS) project for the RX-78 series. The materials used in its construction include a thin layer of Luna Titanium Alloy.

The Chobam Armor granted the Gundam superior defensive capabilities, allowing it to easily withstand a direct hit from the Kampfer's shotgun and protecting it from the explosion of the chain mine. However, it significantly increased the suit's weight, reducing maneuverability and mobility. To counteract these drawbacks, the armor plates on the rear skirt feature built-in thrusters, and certain sections of the armor have movable flaps to ensure that some of the mobile suit's thrusters remain usable.

This armor was later utilized in the RGC-83 GM Cannon II. When equipped with the Chobam Armor, the Gundam NT-1's model number and name change to RX-78NT-1FA Gundam NT-1・FA.
