Each eagle strafing round bullet does 350 AP 5 damage. One burst fires 100 of them. The armor plates are armor level 5, so there is a .65 damage modifier that reduces the damage dealt to 22,750. 25% of those rounds explode with 350 points of AP6 explosive damage. That adds an extra 8750 points of damage. All combined that's 31500 damage.
A 500kg bomb inflicts 2000 points of AP7 damage on a direct hit and an additional 1500 AP6 explosion for a total of 3500 damage. The armor plates though only pass 10% of any damage received on to the lord's 150k HP pool, so just assume any damage is being reduced by 90% until you finish cracking open an armor plate.
The exposed flesh underneath the armor plate is 100% immune to all explosive damage because swedish realism :^)
