Heckler & Koch HK416 is widely known for its use by Navy SEAL units. It’s one of a SEAL’s main weapons, and was recently used to kill Osama Bin Laden. An HK416 weigh 6.5 to 8.5 pounds and can be bought by U.S. civilians all across the United States.
Almost every division of the U.S. government and military force uses the Heckler & Koch HK416, including the CIA, FBI, Marine Corps and even the NASA Emergency Response Teams. The weapon has become quite popular due to its lightweight, high reliability, and easy customization.
The Glock 19
It costs over a million dollars to train just one Navy SEAL, so you’d expect them to get only the best when it comes to weapons. In 2006, Navy SEALs decided to ditch their standard SIG SAUER P226 handguns in favor of the Glock 19. This switch caused a massive bump in Glock handgun purchases.
Glock 19's weigh 1.5 pounds when unloaded, making them about 50% lighter than the SIG SAUER P226 MK25. The biggest benefit for Navy SEALs when using a Glock 19 is that they're much easier to handle than their previously issued handgun. This helps improve aiming skills, drawing skills and more.
The Evolved Sea Sparrow
The RIM-162 ESSM, also known as the Evolved Sea Sparrow, is a stronger and more advanced version of the aforementioned Sea Sparrow Missile. These upgraded missiles feature counter supersonic maneuvering abilities, making them very hard to intercept in mid-flight.
Evolved Sea Sparrows work in tandem with the Aegis Combat System, which holds up to four of these at once. Such advanced missiles don’t come cheap, as each one costs a million dollars. This means that your average fully-loaded Aegis Combat System is carrying about four-and-a-half million dollars’ worth of equipment.
The AIM-9 Sidewinder
The AIM-9 Sidewinder is a series of short-range missiles that are the primary weapon for U.S. aerial warfare. Sidewinders are credited with more than 300 take-downs of hostile aircraft. These missiles highly cost-effective, and exist in a large and abundant supply for the United States Military.
It’s been reported that the military has amassed more than 110,000 units of these. The AIM-9 Sidewinder uses state-of-the-art heat-seeking technology that helps guide the missile towards its targets. Another major feature of the Sidewinder is its on-board infrared sensor, which enables it to accurately track its targets.
The Trident II (D5) Missile
UGM-133A Trident II missiles are some of the Navy’s most important and deadly ballistic weapons. A single Trident II missile can annihilate a small country, or cripple a larger one. They're one of the reasons why nobody ever goes to war with the United States. Such powerful missiles aren’t cheap, as each Trident II costs around $30 million.
Trident II missiles are extremely heavy, and weigh around 130,000 pounds. The U.S. Navy currently has fourteen Ohio and four British Vanguard-Class submarines that carry the Trident II. Each Ohio has twenty-four of these loaded, and each British Vanguard has sixteen.
