The 110 is probably the attacker carrying the most destructive power in game.
2x500kg, 4x50kg, 750rds of 20mm and 255 rds of 30mm add up to a total destructive power equivalent of 8,512lb. Before the vehicle base layout was changed, a single 110 could shut down such a base by killing all three vehicle hangars all by itself.
Edit: It's not the number 1. B-25H carries a DPE of more than 10,000.
