How many cannons does a destroyer have?

Answer 1

Cannons in older ships were primarily for ship-ship combat, which hasn't been a factor in naval warfare since the missile age arrived after WWII. Bow cannons today on Destroyers are primarily for dealing with smaller vessels, though they can do significant damage.

With today's modern Destroyers, typically only one bow cannon; most Destroyers today are DDG's (Guided Missile Destroyers) , and will use guided missiles as their primary means of ship destruction rather than a cannon.

Answer 2

A destroyer typically has multiple cannons, commonly known as naval guns. The specific number and size of the cannons vary depending on the class and design of the destroyer. Modern destroyers generally have various types of cannons, including smaller caliber guns for close-in defense and larger caliber guns for long-range naval gunfire support.
