This is how massive Navy ships get their fresh water

When ships deploy out to sea, it's important they bring the fuel and spare parts they need. The ship's crew also needs to be supplied. While food is often transferred to these ships, there's also the pressing need for the crew to drink.


Although they're surrounded by water, the ocean upon which these ships float isn't exactly the best thing to drink. The National Oceanic and Atmospheric Administration points out that if you drink sea water, you get more dehydrated and, ultimately, dehydration kills people. Drinking seawater brings about other health problems that can cause problems on board ship, specifically the head.

It used to be that ships had to carry water that was safe for drinking. This made crossing oceans difficult to say the least. The sailing frigate USS Constitution (ex-IX 21), one of the original six frigates built for the United States Navy, had a crew of 450. Humans need to drink nearly a gallon of water a day, according to the Mayo Clinic, which, as you can imagine, meant carrying a lot of fresh water as cargo.

Well, today, making sure the sailors have plenty of fresh water for all their needs is much easier. The Navy can do this thanks to the Light Weight Purification System. It just takes one sailor to operate, and it can handle anything from sea water to fresh water. According to a Marine Corps document, this system can purify 75 gallons of water per hour.

The Navy, of course, has other systems that can handle larger amounts, but the Light Weight Purification System is very mobile, which becomes very useful for Marines on the front lines. Learn more about this system in the video below:

It's been 10 years since the Air Force retired the Nighthawk

It's been 10 years since the United States Air Force retired the F-117 Nighthawk (an aircraft so secret, Nevada folklore labeled it a UFO).

"The Nighthawk pilots were known by the call sign 'Bandit,' each earning their number with their first solo flight. Some of the maintainers were also given a call sign," said Wayne Paddock, a former F-117 maintainer currently stationed at Holloman Air Force Base, New Mexico.

7 types of people you meet in a deployed 'tent city'

You'll never get a more true-to-life snapshot of the other branches than the one you get when you begin your deployment. Everyone from every branch (and occasionally every allied nation) is crammed in together in a transient barracks — also known as a "tent city."

It doesn't matter what type of unit you're in, everyone gets put in the same tents and the results are hilarious. Here's who you'll meet in these temporary towns.

NASA just discovered what Uranus smells like

Even after decades of observations and a visit by NASA's Voyager 2 spacecraft, Uranus held on to one critical secret — the composition of its clouds. Now, one of the key components of the planet's clouds has finally been verified.

A global research team that includes Glenn Orton of NASA's Jet Propulsion Laboratory in Pasadena, California, has spectroscopically dissected the infrared light from Uranus captured by the 26.25-foot (8-meter) Gemini North telescope on Hawaii's Mauna Kea. They found hydrogen sulfide, the odiferous gas that most people avoid, in Uranus' cloud tops. The long-sought evidence was published in the April 23, 2018, issue of the journal Nature Astronomy.

This new guided-missile frigate packs a lot of punch

USS Freedom (LCS-1), the lead of the Freedom-class of littoral combat ships, brought some much-needed positive attention to the LCS in 2010 when it carried out a deployment in Southern Command's area of operations. In just seven weeks, it made four drug busts while accomplishing a host of other missions.

It's no secret that the development and deployment of the Littoral Combat Ship has been rife with problems. This big success was exactly what the class needed to secure an export order. Well, to be more specific, a modified version of the Freedom has found an international buyer.

Mattis may see himself as the president's 'babysitter'

Defense Secretary James Mattis reportedly views himself as President Donald Trump's "babysitter," and his efforts to restrain the bombastic leader apparently created tensions with former White House national security adviser H.R. McMaster.

McMaster sought to provide Trump with an array of military options against North Korea, but the defense secretary allegedly refused to put all the options on the table in front of Trump, McMaster aides told The New Yorker. Meanwhile, the president reportedly did not pick up on Mattis's alleged attempts at stonewalling, and McMaster declined to expose his colleague.
