I realized that they wouldn't be able to fly in such heavy armor, so here's a writeup to provide an exception for that...
Heavenly Armaments (Su): An angel of wrath can be armed in an instant by magically summoning a suit of golden armor, shield, and sword. The sword functions as a +3 holy longsword, the shield as a lion's shield, and the armor as a suit of +1 light fortification full plate. This supernatural armor allows the angel to fly with no penalty. Upon the angel's death, or when separated from the angel, the weapon, armor, and shield vanishes. An angel of wrath can summon or dispel its own accoutrements as a free action.
Do we want to give them regeneration like the planetar and solar? If so, I'd recommend 5, as the planetar is 10 and solar is 15.
