What is a Navy sub tender?
Description. Submarine Tenders furnish maintenance and logistic support for nuclear attack submarines. These two forward-deployed ships are the vestiges of the previously large fleet of submarine and destroyer tenders and repair ships.
Why did the Navy get rid of tenders?
Naval tenders fell out of use during the late 20th century, as the speed and range of warships increased (reducing the need for advanced basing). By the end of the 20th century, all of the tenders in the U.S. Navy had been inactivated except for two submarine tenders.
Can submarines dock?
Here's how. KITTERY, Maine — Portsmouth Naval Shipyard leaders announced the finishing touches are complete on a $158 million super flood basin, allowing submarines to dock without buoyancy assistance, comparable to a navigational lock.
How do submarines get so deep?
Submarines float on the surface by using ballast tanks full of air. There are valves at the top of the ballast tanks that are opened when it's time for the submarine to submerge. As the air escapes, seawater comes in a the bottom of the tank. It makes the sub heavier, and then it submerges.
How many submarine tenders does the US Navy have?
twoCurrently, the U.S. Navy (USN) has two 1970s-built submarine tenders, the USS Emory S. Land (AS 39) and the USS Frank Cable (AS 40). Both are now home-ported in Guam as of 2018.

At what depth will water crush you?
Can a human be crushed by water pressure? Human beings can withstand 3 to 4 atmospheres of pressure or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot or one atmosphere per 33 feet of depth and presses in from all sides. The ocean's pressure can indeed crush you.
Why do submarines crush?
The pressure outside the sub, however, is determined by the depth. As a result, you have a tremendous difference in the pressure inside the sub (which pushes the walls of the sub outward), and the pressure outside it (which acts to crush it).
What are submarine tenders? What are their functions?
Description#N#Submarine Tenders furnish maintenance and logistic support for nuclear attack submarines. These two forward-deployed ships are the vestiges of the previously large fleet of submarine and destroyer tenders and repair ships. Although their sister ships were decommissioned after the Cold War, the two L.Y. Spear-class tenders Emory S. Land and Frank Cable are important assets intended to serve into the mid-2020s. Both ships remain commissioned U.S. Navy units and have hybrid crews of military and civilian personnel. MSC CIVMARs assumed responsibility in 2008 to man, operate and maintain the ships, while uniformed Navy personnel, under the command of a U.S. Navy captain, handle the mission roles. Both ships have been given modernization and habitability upgrades. The ships routinely deploy throughout the Western Pacific and Indian Ocean regions.

When will the USS Frank Cable be retired?
The USN plans to retire the USS Frank Cable in 2029, 51 years after its launch, and the USS Emory S. Land in 2030, 53 years after its launch. There’s an entry in the US Navy FY17 shipbuilding plan for an AS (X) submarine tender, but no funded placement is seen out to FY23.
What is a submarine?

What can subs be used for?

Where is the key point for a submarine to successfully dive?
However, the key point for submarines to successfully dive is actually located on its huge tanks, named ballast tanks. At the top of the ballast tanks, there are valves that will open up when the subs are about to dive. Therefore, as the air on the ballast tanks is released, the tanks will fill in the seawater.
How deep can a submarine dive?
Generally, submarines can dive deeper than 800 feet, and although they can stay under the water for long periods, they only limit the duration for 3 months due to the food and supplies stock they bring with.
Why does a cup sink?
Yup, of course the cup will sink. The reason is because when you put pressure on the cup, it will be filled with water. And apparently, the water adds the weight of the cup, causing it easier to sink. Taking the same principle, that's also how submarines work. However, the key point for submarines to successfully dive is actually located on its ...
