How far can a dreadnought fire its guns?

The range of a dreadnought's guns varies depending on the specific type and caliber of the artillery installed. Generally, early 20th-century dreadnought battleships, equipped with 12-inch (305 mm) or larger guns, could fire shells up to 15 to 20 miles (24 to 32 kilometers) effectively. Modern naval artillery on advanced battleships or cruisers can achieve even greater ranges, sometimes exceeding 25 miles (40 kilometers) with advanced munitions. However, effective targeting and accuracy decrease at longer distances.
