30 Firearms Used by the US Navy

The United States Navy employs a range of small arms for the safety and security of its personnel and operations. While the guns the Navy uses may not see as much time on the battlefield as guns the Army or Marines use, they are still important in carrying out naval operations. As such, Navy service members are still trained in the use of these small arms.

At the start, the U.S. Navy typically relied a great deal on small arms, and each Navy soldier was outfitted and trained with pistols, rifles, and swords. Since its inception, first, as the Continental Navy in 1775, and in 1794 becoming what we have today, the U.S. Navy has evolved over the years and much has changed. Today, in addition to its cruisers, submarines, and aircraft carriers, Navy sailors and soldiers still use a large arsenal of small arms.

24/7 Wall St. referenced a catalog of U.S. small arms from Military Factory to identify the firearms used by the U.S. Navy. We ordered these guns by the time they entered the service and included supplemental information regarding the type of firearm, range, caliber, and manufacturer also from Military Factory. (Compare this list to the 26 guns in the U.S. Army arsenal.)

One of the Navy’s standard sidearms for at least a few decades is the Beretta M9. This semi-automatic pistol is chambered for the standardized 9x19mm Parabellum pistol cartridge. The M9’s effective range and large ammunition capacity make it an ideal choice for Navy personnel.

The Colt M4 carbine continues to be the primary service rifle across the Navy, much like some of the other U.S. armed forces. This compact variant of the M16 rifle is particularly effective in close-quarters and boarding operations. The M4’s reliability and modular options make it an ideal choice for various naval combat scenarios. Not just the M4 carbine, but over time, many of these weapons have been updated. (Also see: This military has the most guns.)
