Why do modern ships only have one gun?

Distance travel, survival of fierce sea states, and other considerations had to be added to modern Naval sea power calculations. As others have previously answered, guns have mostly been replaced by missiles for anti-shipping missions and anti-air defense.

Do destroyers have armor?

Destroyers have never had armor belts, one reason destroyers also are known as “tin cans.” “Speed is among their defenses,” Paul Stillwell, director of history for the U.S. Naval Institute in Annapolis, said of destroyers, and the weight of an armor belt would slow them down.

Are warships still armored?

The emergence of guided missiles in the last part of the 20th century has greatly reduced the utility of armor, and most modern warships are now only lightly armored. Naval armour consists of many different designs, depending on what the armour is meant to protect against.

Why do modern ships have so little armor?

The reason that ships have little armour nowdays is because ships have become more expencive to build and fill with electronic equipment, gone are the days of 8 inch thick steel to stop 14 inch shell’s, today we fire a volly of missiles so in comparison firing a 14 inch shell would be like taking a pea shooter to a cannon.

Is armarmour worth it?

Armour is just useless. SS-N-19 and 22 are heavy anti ship missiles they have warheads 4 times the size of harpoon and exocet and go faster and further. These missiles can be fitted with nuclear war head’s but they are confined to conventional for now.

How effective is spaced armor against shaped charges?

Experience with HEAT hits on tanks also shows that if the warhead doesn’t hit a fuel tank or ammo storage, the tank can usually be repaired, which is much less often the case with kinetic hits. Furthermore, again, spaced armor has proved quite effective against shaped charges, and there’s a lot more room on ships for spaced armor than on AFVs.
