|T-51b Power Armor|
The T-51b Power Armor is a rare variation of Power Armor found in Fallout 3. With a Damage Resistance of 50 it was the strongest armor in the game until the third DLC pack Broken Steel was added, now it shares the spotlight with the Enclave Hellfire Armor.
The T-51b Power Armor is much more durable than regular Power Armor, however there's no other armor to Repair it with. The only way it can be repaired is through a Caravan Merchant or someone else with repair skill. Wearing this armor will add +1 to your Charisma and +25 to your Radiation Resistance.

There's only one set of this armor in the game and it's found in Fort Constantine during this quest. You will need to obtain a key from 3 different people in order to get the armor. Dave, Dukov and Ted Strayer all have the keys that you'll need.
- T-51b makes excellent armor for a companion to wear especially if you are playing Fallout 3 "Vanilla" (Fallout 3 without mods).
