Hearing that, Tony glanced at Luke again. No wonder this guy had been in a hurry to round up so many 'players' and train them to fly the 'cannon fodder' fighter planes.
T'Challa nodded. "I have about 2,000 fighter planes. Including Bruce's, they should be useful enough."
As for the battleships, nobody mentioned them. These took time to make, and T'Challa and Luke knew very well how many there were.
Thanos's warship was equivalent to an 'air base' for fighter planes, while Earth's fighter planes were mainly land-based.
In terms of speed and agility in the air, the fighter planes couldn't compare with Thanos's warship.
In particular, Wakanda's vibranium fighter planes were lethal enough to destroy the warship's protective shield.
Thus, whichever side could destroy the enemy's fleet of fighter planes first could suppress the enemy's base.
Once the base was destroyed, the enemy would have lost 80% of the battle.
