Which units in the Gundam 00 universe are confirmed to have/use GN composite armor?

I only know of the Plutone and Full Armor 0 Gundam.

Yes only those two are officially confirmed.

The generic GN armor (at least for Exia gen and beyond) is implied to be GN Field on the surface, much like how the physical GN Shield usually works.

So, all Gundams (all factions) from Exia onwards have GN armor?

Do any of the non-Gundam MS/MA have GN armor?

Not stated, but there's very little reason to believe they don't if we take the assumption that Ptolemaios 3rd Gen Gundams and Trinities Gundam Thrones have them. Most of the future Gundams are stronger than these two series and there is no mention of a defensive downgrade.

any of the non-Gundam MS/MA have GN armor?

Again not stated, but they pretty much have all the other aspects of GN tech so there's very little reason to think they don't.

Thanks for the replies, SonicSP.

So, minor update but while discussing and researching a different 00 tech topic with someone, came across a chart in the Final Mechanics book that links GN Drive and GN Drive Tau with "Armor" usage. Basically the chart explains the typical energy flow of Original/Tau Drive MS.

I drew a chart in text with basically the translation of it, although I had to move some positioning around/compress some things together.

Basically, alongside Beam and Thruster, Armor is a general category that GN Drives also power in MS.

It doesn't really 100% confirm that all GNMS have full body GN-based armor or anything since just one part of the MS, like the shield for example, can still be enough to count. However it does add more credence to the idea that some level of GNMS armor strengthening is standard.

Not exactly sure what Electrical Drive (駆動用 電気/Kudō-yō denki) means, but in English engineering it seems to refer to Electrical motors and actuators apparently. So frame and joint movements I guess.

Also "Hybrid" in the Pseudo Drive chart refers to a category of Tau MS equiped with both a Pseudo GN Drive and a seperate Battery (they both power the Electrical Drive, based on the chart arrow direction). Currently only the Ahead is confirmed to be a Hybrid type, while the circa 2314 new generation Tau units are only ones confirmed to be full stand alone types (not requiring a seperate Battery).
