# 7 of the most lethal Navy weapons in history

![](<https://www.wearethemighty.com/wp-content/uploads/legacy/assets.rbl.ms/17290091/origin.jpg>)

The Navy has the mission of [securing American interests on the ocean](<https://www.wearethemighty.com/mighty-history/uss-conestoga-navy/>), otherwise known as "most of the planet."

## Here are 7 of the most lethal Navy weapons in history

### 1. Tomahawk Land Attack Missile- one of the most dangerous weapons

At $569,000 apiece, Tomahawks are expensive cruise missiles that pack a huge punch. They fly at 550 mph and have a maximum range between 700 and 1350 nautical miles, depending on which version of the missile is used. They can carry either 166 bomblets, a 1,000-pound conventional warhead, or the W80 nuclear warhead with a 5-150 kt yield. The Block IV Tomahawk missiles can even be reprogrammed in flight to hit different targets.

### 2. MK 48 Heavyweight Torpedo

The [MK 48 heavy torpedo](<https://www.navy.mil/navydata/fact_display.asp?cid=2100tid=950ct=2>) has 650 pounds of high-explosives packed into its warhead. It can swim at 28 knots for more than 5 miles to reach its target, homing in on it with an advanced sonar system. The Mod 7 version has sonar and guidance for better engaging targets in both deep and littoral waters while getting past enemy countermeasures.

### 3. Trident II Ballistic Missile

Deployed aboard Ohio-class ballistic missile submarines, each [Trident II](<https://www.navy.mil/navydata/fact_display.asp?cid=2200tid=1400ct=2>) can carry 14 independently-targeted nuclear warheads. The warheads can be the W76 with a yield of 100 kt or the W88 which yields a 475-kt explosion. The submarines were built to carry 24 each. The number of nuclear warheads on a Trident II was limited to eight and the number of missiles on each submarine was limited to 20 by nuclear treaties.

### 4. Standard Missile (There's really nothing standard about this weapon)

The Standard Missile has a boring name but awesome capabilities. It's a family of missiles that are primarily for shooting down planes and helicopters but can also attack ships, cruise missiles, and ballistic missiles. One even [took out a satellite](<https://www.raytheon.com/news/feature/rms13_ftm22a.html>).

Currently, different missiles are needed for different missions. The [SM-2](<https://www.raytheon.com/capabilities/products/sm-2/>) can cripple an enemy ship while the [SM-3](<https://www.raytheon.com/capabilities/products/sm-3/>) focuses on ballistic missiles. The youngest member of the family may change that. The SM-6 has successfully engaged cruise and ballistic missiles and [may be ](<https://breakingdefense.com/2015/08/sm-6-can-now-kill-both-cruise-and-ballistic-missiles/>)[tested](<https://breakingdefense.com/2015/08/sm-6-can-now-kill-both-cruise-and-ballistic-missiles/>)[ against surface ships in the future](<https://breakingdefense.com/2015/08/sm-6-can-now-kill-both-cruise-and-ballistic-missiles/>).

### 5. MK 50 Advanced lightweight torpedo

While the MK 50 is much lighter than the MK 48 above, it still hits with an impressive 100-pound warhead and can swim at a blistering 40 knots. Designed to chase down and destroy double-hulled nuclear submarines, the [MK 50](<https://www.navy.mil/navydata/fact_display.asp?cid=2100tid=1000ct=2>) was created to get past torpedo countermeasures and kill the enemy, even in shallow water. It's one hell of a weapon.

### 6. Laser Weapon System

Yes, this weapon is exactly what it sounds like. Already deployed aboard the USS *Ponce*, the Navy's Laser Weapon System concentrates light into a fine point, heating a target until it burns or explodes. So far, the laser has only been used in tests but the crew of the USS *Ponce* is allowed to [use the laser to defend the ship](<https://www.stripes.com/news/us/navy-authorized-to-use-new-laser-weapon-for-self-defense-on-uss-ponce-1.318735>) from actual threats. The laser can fire at different targets in rapid succession. Since shots cost less than a dollar each, double-tapping is probably fine.

### 7. Railgun

Like the laser above, the railgun is currently serving on only one Navy ship. The USNS *Millinocket* carries the prototype weapon, essentially a cannon that uses magnets instead of chemical propellants to fire a round over 110 nautical miles. Because the round is moving so fast, it can bust bunkers and other hard targets without the need for explosives. Also, the [railgun is expected](<https://www.navy.mil/submit/display.asp?story_id=80055>) to be able to engage missiles, speedboats, and aircraft at a fraction of the cost of other weapons.
