Yes, they do. It became standard practice to add antiaircraft guns and autocannons to the defenses of naval vessels (which had previously relied solely on antiaircraft missiles) after lessons learned from the Falklands War, in which Argentine aircraft were able to attack British ships by flying extremely low at altitudes where they could not be engaged by missiles.
Then the various antiaircraft guns erupted, downing the plane within seconds.
The guns used in war to shoot down planes are called antiaircraft guns.
They used mostly antiaircraft guns and shot guns

That is a type of ship A small, fast, highly maneuverable warship armed with guns, torpedoes, depth charges, and guided missiles.
Most U.S. destroyers have at least one or two guns, several anti aircraft systems, surface to surface and surface to air missiles, As well as Anti submarine systems, either depth charge or helicopter based.
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.
After the terrorist threat, countries all across Europe had antiaircraft missiles armed and ready.
