Naval Weapons

Category Overview

Overview

Naval weapons are weapons systems designed for or primarily employed in maritime warfare. The constraints of the naval environment — salt water, limited space, the need to project force at sea — have driven distinctive weapons development separate from land warfare, though many technologies cross over. Naval weapons development is closely linked to warship design: the weapons a ship carries determine its function, and the need to carry specific weapons shapes the ship.

Historical Development

Ancient Naval Warfare (Bronze Age – Roman era)

• Ram (embolon) — The primary naval weapon of the Mediterranean; a bronze projection from the waterline of the galley; rowed at speed into the hull of an enemy ship; the trireme was optimized as a ram platform
• Marines and boarding — Soldiers aboard ships fought hand-to-hand after ramming or grappling; catapults and ballistae adapted for ship mounting

Medieval and Early Modern (500–1600)

• Greek fire — Byzantine incendiary weapon; pumped onto enemy ships; burned on water; decisive in several naval battles
• Crossbow and longbow — Naval archery; aimed at rowers and crew
• Grappling hook — Iron hook on rope; pulled ships together for boarding

The Age of Sail (1500–1850)

• Ship-mounted cannon — The defining naval weapon; arranged in broadside batteries along the ship's sides; a first-rate ship of the line carried 100+ guns
• Round shot, chain shot, bar shot — Solid ball for hull penetration; chain/bar shot for cutting rigging
• Carronade — Short-barreled, large-bore; fired heavy balls at short range; devastating in close action
• Mortar (bomb vessel) — Specially built ships carrying mortars for shore bombardment

Industrial Era (1850–1945)

• Naval gun — Steel breech-loading rifled guns; range extended to 20+ miles on WWI/WWII battleships
• Torpedo — Self-propelled underwater projectile; invented 1866; transformed naval warfare by threatening every warship regardless of armor
• Naval mine — Anchored explosive; denied sea areas; both world wars saw extensive mine warfare
• Depth charge — Anti-submarine weapon; barrel of explosive dropped or launched from surface ships
• Aircraft and carrier aviation — Rendered the battleship obsolete; the aircraft carrier became the dominant naval weapons platform
