Winterized T-51b Power Armor

The special winterized version of T-51b Power Armor appears in the Operation: Anchoarage DLC for Fallout 3. It is used by NPCs in the simulation and can be obtained from the weapons vault after completing the Operation: Anchorage simulation. It appears to be identical to the T-51b in Fort Constantine other than having a lack of rust and the main body of the suit has only 45% damage resistance compared to the rusted version's 50%.

In at least one players game, the item could be worn before the player completed the necessary quests to receive the power armor training perk. It is unknown at this time if this is a bug, if it applies only to this armor suit, or if completing the DLC grants power armor training to the player.

Additionally, it has been reported that this armor does not have its condition decline while equipped.
