Why a naval 5-inch gun is too large for a normal tank

Could a naval 5-inch gun be adapted into a universal artillery and tank weapon on land?

It is technically possible, but the vehicle needed to carry the naval gun and ammunition would grow far beyond the scale normally desired for a tank.

The naval weapon's barrel, breech, recoil forces, and ammunition impose a much larger installation than the caliber number alone suggests. A later comparison contrasts a roughly 29.5-foot naval 5-inch weapon with an M1 tank gun installation of about 18 feet. The naval gun unit is put near 21.7 tons, roughly a third of the stated mass of an entire M1A2 tank. A specialized artillery vehicle might carry it, but an ordinary tank would have to become substantially larger and heavier. The adaptation conflicts with the mobility and size requirements of armored warfare.
