I wouldn't trust those giant airships. If there is anything I learned from history and weapons development, bigger vehicles require more/bigger engines and more fuel.

You just got to love the Square/Cube Law: "When an object undergoes a proportional increase in size, its new volume is proportional to the cube of the multiplier and its new surface area is proportional to the square of the multiplier."

TL;DR, the bigger they are, the harder they fall.
