What Guns Do the Navy Use?
When it comes to naval warfare, firepower is crucial in order to protect ships, sailors, and the nations they represent. The main guns used by the naval forces of various countries can vary depending on the region, enemy threats, and the role of the fleet. In this article, we will delve into the common types of guns used by navies around the world, exploring their characteristics, capabilities, and significance in modern naval warfare.

The Standard Naval Gun (SG), also known as the Common Main Battery (CMM), is a widely-used, standardized gun caliber on naval ships. The US Navy, for example, uses the 5.8-inch (14.7 cm) Mark 45 Mod 4 cannon, which is mounted on the Arleigh Burke-class guided-missile destroyers. Similarly, the Royal Navy employs the 113 mm (4.46 in) Mark 8 gun on its Type 45 destroyers, while the French Navy uses the 76mm (3 in) DRBC 32 gun on its Horizon-class destroyer.
Table: Comparison of Standard Naval Guns
| Gun Caliber (mm) | Country/Navy | Ship Class/Type | Characteristics |
|---|---|---|---|
| 5.8-inch | US Navy | Arleigh Burke-class | High firing rate, long-range capacity |
| 113mm | Royal Navy | Type 45 | Enhanced anti-air capabilities, better armor penetration |
| 76mm | French Navy | Horizon-class | Multi-purpose gun, decent anti-air and anti-submarine capabilities |
Anti-Torpedo Guns
Given the growing threat of Anti-Ship Missiles (ASMs) and Towed Lateral Obstructing Device (TLOS) anti-torpedoes, navies need specialized guns to counter such threats. The 15.2 cm (6 in) Mark 63 gun is used on US Navy LCS-class littoral combat ships for anti-torpedo and anti- surface warfare. Similarly, the 40mm Bofors RWS (Remote Weapon Station) is used on Danish Navy Iver-class frigates as an anti-torpedo and anti-air defense gun.
Table: Comparison of Anti-Torpedo Guns
| Gun Type | Country/Navy | Ship Class/Type | Characteristics |
|---|---|---|---|
| 15.2 cm Mark 63 | US Navy | LCS-class | High-tech anti-torpedo weapon, modular design |
| 40mm Bofors RWS | Danish Navy | Iver-class | Lightweight, maneuverable, and effective vs. TLOS |
Shore-Based Guns
Many navies also employ ground-based guns for coastal defense, amphibious operations, and counter-terrorism. Examples include the 130 mm (5.12 in) Coastal Defense Gun System used by the Chinese Navy for coastal defense duties and the 76.2 mm (3 in) field gun deployed by the US Marine Corps’ Amphibious Assault Ship (MV-22 Osprey) for amphibious support.
Table: Comparison of Shore-Based Guns
| Gun Caliber (mm) | Country/Navy | Purpose | Characteristics |
|---|---|---|---|
| 130 mm | Chinese Navy | Coastal Defense | Long-range, high-destructive capacity |
| 76.2 mm | US Marine Corps | Amphibious Support | Lightweight, versatile, multi-role gun |
As naval gun technology advances, navies are adopting more advanced platforms, such as rail-guns, laser guns, and advanced conventional guns, to improve their firepower while reducing maintenance and logistical constraints. The US Office of Naval Research (ONR) is developing advanced gun technology, including Railgun technology, which combines electric propulsion with advanced artillery. The French Defence Procurement Agency (DRASSM) is actively exploring advanced gun technology options, such as the innovative DGA-25 railgun.
Conclusion:
Naval guns remain a vital component of sea-based military power, influencing naval operations, tactics, and strategy. From coastal defense to amphibious and anti-torpedo firepower, each gun type possesses unique characteristics, capabilities, and roles. As advanced gun technology continues to unfold, naval forces will inevitably adopt these innovations to achieve a more effective and robust defense capability.
