Meet the Navy’s MK45s. These large and terrifying rifles can shoot down almost any aircraft with just a single hit. They are fully automatic and shoots 5-inch bullets that cause unbelievable damage upon impact. Mark 45 Guns are mostly used against flying aircraft, although some land targets have been destroyed by them.
These turrets are mounted on almost every U.S. Navy vessel. It can shoot up to twenty shots per minute, and will easily tear apart even the most armored targets. Mark 45 guns are also much more economical than missiles, as each bullet “only” costs around $75,000 per shell, compared to the Navy’s missiles, which cost over a million dollars per unit.
The B61 Nuclear Bomb
The most terrifying weapon in the United State Navy's arsenal without a doubt, the B61 nuclear bomb. After the Cold War ended, Uncle Sam was left with more than 3,000 of these. They were promptly cached into an unused arsenal of weapons, often called The Enduring Stockpile. It contains about 23,000 deadly weapons from the time nuclear weapons were still legal.
The B61 nuclear bomb has a maximal yield of up to 340 kilotons. It weighs about 700 pounds and causes untold chaos. The United States is opposed to the use of them, and actively hunts down the last free remnants of these bombs.
The Phalanx CIWS
The Phalanx CIWS, otherwise known as Sea-Wiz, is a close-in weapon system that destroys hostile anti-ship missiles and helicopters. It’s the last line of defense for U.S. vessels and can save units from incoming missiles. They fire a rapid succession of bullets and use a computer-controlled radar to hit their targets automatically.
The Phalanx is outfitted on almost all of the U.S.’s Navy ships and usually holds the aforementioned M61 Vulcan cannon. The combination of these two creates an extremely potent defense system and helps save many lives.
The Mark 54 Lightweight Torpedo
The Mark 54 Lightweight Torpedo is a standard 12.75 inch torpedo used to destroy hostile submarines. It’s been in the Navy’s use since 2004, and is manufactured and sold by American defense contractor, Raytheon Systems. Each torpedo costs about $840,000 and weighs 608 pounds. They travel underwater at 46 miles per hour, making them faster than the world’s fastest submarine.
Mark 54 Lightweight torpedoes are currently in use by many modern Navy forces all across the world. These state-of-the-art torpedoes were developed due to various issues that were discovered in previous versions, namely the Mark 46 and Mark 50 torpedoes.
The M91A2
Another sniper-rifle often used by Navy SEALs is the M91A2. It is manufactured by Redick Arms Development. The M91A2 is one of DEVGRU’s most popular weapons, and countless terrorists have been put to sleep using this incredible tool.
The M91A2 weighs about 14 pounds, and is 43 inches long. Like the SOCOM MK 13, it can effectively shoot up to a range of 0.75 miles. Once shot, the bullet travels at about 2,500 feet per second, making it an extremely deadly tool for long-distance targets.
