Why do subs not have windows?

Submarines spent most of their operational time submerged and a window would do no good. When they do operate on the surface, they post men topside, both as lookouts and to navigate the boat. Windows would be a spot of weakness in the pressure hull.

Do any military subs have windows?

Military submarines travel underwater in an environment of total darkness with neither windows nor lights. Operating in stealth mode, they cannot use their active sonar systems to ping ahead for underwater hazards such as undersea mountains, drilling rigs or other submarines.

Can you have windows on a submarine?

No, Navy submarines don't have windows or portholes so the crew can watch undersea life. Submarines have only periscopes for outside vision, and those are only used close to the surface, a periscope depth (PD).

Why do some Russian submarines have windows?

The windows on the sail of submarines are used when it is on the surface as a windbreak and to be able to see what is ahead of you.

Why can't females be deployed on a submarine?

First, a submarine is almost never within six hours of emergency medical care. Medical evacuation rates for women have been found to be two-and-a-half times that of men on surface ships, but pregnancy complications would be even more serious in submarines.

Do submarines have toilets?

Pressurised seawater is used to flush the toilets on a submarine. A simple ball valve operates the flush on the toilet which enables the toilet to be 'plumbing free'. Once flushed, you then manually turn a valve next to the toilet to refill the bowl.

How do submarines sink if they are full of air?

When the submarine dives, water is pumped into the ballast tanks to replace the air. This makes the density of the submarine greater than the density of the water and the submarine sinks.

What is the longest a submarine has stayed submerged?

The longest submerged and unsupported patrol made public is 111 days (57,085 km 30,804 nautical miles) by HM Submarine Warspite (Cdr J. G. F. Cooke RN) in the South Atlantic from 25 November 1982 to 15 March 1983.

Do submarines have air conditioning?

In conventional submarines, the renewal of the air occurs with the use of the snorkel or when it is in the sea surface. The cooling machinery consists of two identical plants, one either side of the ship's center line, working in conjunction with the direct-expansion coolers in the diverse air conditioning units.

How long can you shower in a submarine?

There is also the etiquette of shower time -- three to five minutes being what these sailors constitute as being considerate of others since it is all about the "water run time" and the cycling out of dirty water for clean water these sailors must do.

Can you smoke on a submarine?

So the Navy banned smoking aboard submarines not with the stated purpose of curing the smokers, but of protecting nonsmoking submarine crew members from the threat of heart and lung disease from secondhand smoke.

Can you wear deodorant on a submarine?

In the enclosed atmosphere of the submarine, these pollutants can build up and pose a health risk. Therefore, aerosol cans (such as hair spray, shave cream, spray deodorant) are not authorized to be brought on board.

Do submarines get WIFI?

Submarines are sometimes equipped with on-board devices that can connect to the internet with higher data rates, including via satellite, but these can only be used when submarines rise to the surface.

Can a submarine survive a tsunami?

The ocean could be affected by high tsunami and/or pressure waves in the case of a large asteroid or comet impact. Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves.

How long could ww2 subs stay submerged?

The sub could stay submerged for 48 hours, and had a patrol duration of 75 days. Later classes of submarines improved depth and other features, but the speed and duration remained the same.

Has the U.S. ever lost a submarine?

Scorpion was lost with all hands on 22 May 1968. She is one of two nuclear submarines the U.S. Navy has lost, the other being USS Thresher. She was one of the four mysterious submarine disappearances in 1968, the others being the Israeli submarine INS Dakar, the French submarine Minerve, and the Soviet submarine K-129.

Has a submarine ever pulled down a fishing boat?

In November 1990 the pelagic trawler Antares sank in the Firth of Clyde with all four crew members on board all losing their lives. The loss of the vessel was immensely controversial as it emerged that the Antares was sunk when its nets became tangled with a Royal Navy nuclear submarine that passed underneath.

Can you run out of oxygen in a submarine?

A submarine is a sealed container that contains people and a limited supply of air. There are three things that must happen in order to keep air in a submarine breathable: Oxygen has to be replenished as it is consumed. If the percentage of oxygen in the air falls too low, a person suffocates.

What happens to toilet waste on a submarine?

Many spare parts are partially unpacked before being stored aboard. Waste that is discharged overboard must either be pumped out against the ambient sea pressure or blown out using pressurized air. Waste materials are collected and periodically discharged.

Can females serve on submarines?

Female officers have been going to sea in submarines since 2011. Three years later, the plan to incorporate enlisted women was announced, which took lessons from the past 40 years of integration of women into other Navy communities.
