Every Major Type of WWII Naval Artillery Explained

From battleship main guns and Yamato's record-setting 18.1-inch rifles to Bofors autocannons, radar-directed fire control, and the U.S. Navy's forward-throwing Hedgehog and Squid mortars, this video explains every major type of naval artillery fielded during World War II. We break down the major types and show what made each one different: heavy battleship rifles, super-heavyweight guns, battlecruiser and pocket-battleship main batteries, French quadruple turrets, casemate secondary guns, British and American dual-purpose guns, heavy anti-aircraft guns, Bofors 40mm and Oerlikon 20mm autocannons, the late-war 3-inch/50, British pom-pom mounts, heavy and light cruiser main guns, destroyer guns, torpedo-boat cannon, escort-corvette and submarine deck guns, shore-bombardment and monitor-class guns, star shells, optical directors, radar-directed fire control, depth charge throwers, Hedgehog, Mousetrap, and Squid, landing craft gun and rocket support ships, coastal defense batteries, and defensively equipped merchant ships. The video also follows the engineering and tactical problems behind each type: why a heavier shell wasn't always the answer, how dual-purpose guns tried to solve two jobs with one weapon, why radar turned naval gunnery into a prediction problem before an enemy was even visible, how a forward-thrown mortar beat a depth charge dropped blind, and why the deadliest anti-aircraft answer of 1945 was more automatic barrels packed onto one mount rather than one bigger gun. Finally, we look at the tradeoffs each navy accepted: Japan's single decisive gun versus America's layered defense in depth, Britain's compromise dual-purpose mount, and the small, unglamorous weapons — Hedgehog, Mousetrap, DEMS guns — that quietly did some of the war's most efficient killing.
