Besides, what payload of 4 million pounds (2,000 tons) would fit into the
payload capsule?

That is the weight of a large WW II destroyer warship.

Good question. Maybe the military has thought of something. Why yes
they have: tungsten rods

The Air Force's 'rods from god' could hit with the force of a nuclear
weapon ? with no fallout

Imagine dropping 4 million pounds of tungsten rods on your enemy's
underground fortifications.

Interesting that you mention tungsten. It is a very dense material, 2.7 times
the density of iron.

Specific Gravity
Aluminum --- 2.80
Iron ------- 7.13
Lead ------ 11.34
Tungsten -- 19.25
Gold ------ 19.32
