Why Do SMALL HOLES on Aircraft Carriers Constantly Release Water?
Вставка
- Опубліковано 16 бер 2024
- Between the runways for jet fighters and the constant buzzing of activity on the flight deck, hides a small but intriguing detail that is often overlooked: a small hole that incessantly discharges water. What could be the function of this mysterious hole? Is it merely a drain for rainwater, or does it conceal an engineering contrivance essential to the operation of the ship? #usnavy #aircraftcarrier

Over 360,000 illegal aliens jumped the USA border this year. Does anyone monitor or care about the environmental impacts and discharge of that sludge... I would say that about 10 Aircraft Carriers could take a great big giant dump in the middle of Manhattan and not even close to equal that....
😊😊
😊😊
Not with these poorly scripted, super repetitive, void of quality information videos bro. Y'all need to write better scripts. Even if the information being shared is limited, it can be presented in a way that will cause your viewers to want toe stch to the end.
Knew the question posed, would take forever to reach. My guess is that it's cooling water for the nuclear propulsion systems.
Jesus, explain the point of the video without talking endlessly about aircraft carriers.
What?!
They need to waste time. Explaining the holes would take about 2 min.
Facts I still don’t know what they’re for and I wanted to know
Left after the first minute and a half. Couldn’t take it
Que extensa la explicación de que es un porta aviones! Muy pesado!
Why don't you get to main point. Holes drains in the aircraft carriers? You waste our time by talk talk talk.
Hahahahahahahahaha
It's a Navy production. What did you expect.
I agree with you 100%.
Thanks :) I skipped the video after 1min bc i realized its gonna be a time grab. So your 2 sentences helped me skip this video. Also reading comments and writing this long text was worth my time more than watching this video that just does not come to the point. Thanks.
That's the point - pad the content, sound more impressive, and allow more ads. If they got to the point, this would be a youtube short.
That seawater is used to cool more than just machinery. I was on the Forrestal in 82, as a radar ET. The radar I maintained had a water cooled transmitter. Of course, you can't use seawater to cool electronics. The radar had a distilled water loop that cooled it. However, that just transfers the heat away from the radar transmitter and into its cooling unit. There was a freshwater loop that cooled that cooling unit, transferring the heat from the cooling unit to a neighboring pump room. In that pump room, that freshwater loop was cooled by a constant flow of water from the fire main. Which is fed by seawater, as are most things that don't need freshwater. So, ultimately, that water flowing out of those small holes also completed the cooling cycle for my radar, transferring its heat into the ocean.
I once had the radar shutdown, overheated. Found that someone doing maintenance on the valve that connected the fire main to my pump room had closed the valve and forgot and left it that way. Which meant no saltwater to cool my freshwater loop. So, the freshwater loop could no longer cool the distilled water loop. So, heat accumulated and the radar shutdown. Thankfully, no damage done to the gear. I think we added a tag to the valve identifying it as belonging to a critical radar system.
Also back then, trash disposal while at sea was simply over the side in bags.
That is a lot of info. Thanks.
SPS-30? I was a 30 tech in the late 60's and early 70's. on Chicago (GG-11) and Forrestal (tho I did not actually work on that one.)
So...the perpetrator that did that is still alive I presume?😅
@@steveurbach3093 SPS-43A, actually. Its antenna was the one on its own platform hanging off the outboard side of the island. Biggest one on the ship, with a grid about 10 feet tall and 30 feet wide. Long range air search. My cruise was its last. We went to SLEP right after that, in 83, and it was replaced by a SPS-49.
I don't actually remember a SPS-30, to be honest. There was the SPS-37 in its dome at the back of the island. Also on its last cruise that year.
Cute story: The tech that took care of the 37 pretty much "lived" in the dome. The only time you found him in his rack, was when he was sick. The dome was nicknamed, "Freddy's penthouse", since his nickname was "Fast Freddy". Near the end of the cruise, as a joke, he submitted a request chit to have that 37 dome moved to his mother's house in Jax, FL (homeport). Everyone up the line played along with the joke, adding comments about "the emotional impact of separating him from the dome", etc. It actually came back approved and was hilarious to read.
And, no, he didn't actually get the dome. Just the chit as a memory.
@@JusticeAlways Presumably. All I can say for sure is, it never happened again. 🙂 I'm sure there were some choice words had between the EMO and their Dept head.
Pertinent info begins at 4:11
And ends at 4:12.
Thank You
You're a hero.
It came from the ship's galley. After cooking our tasty meals the cooking water was pumped overboard as a shark repellant. USS Constellation 1975-1980, VA-146.
That's funny! I never had bad food in the Navy except Treasure Island at "A" school. Used to chase carriers doing plane guard on a tin can.
When I looked at the huge portion on the dinner trays when showing the sailor eating 😊 that seemed to get a large food plate. But seeing the hard working flight deck ( Purple) shirts DRAGGING that big full line around, bet those poor soles build up an appetite 😊
@@rp1645 When I was in there was a ration on what you got to eat, no mater who you were. The "grapes " busted their rears fueling planes, But we all worked like dogs on the flight deck.
@@joemoore4027
YES you are Right SIR about the flight deck
And many moving parts that can KILL if you aren't completely in the game. Thank you
I was on a 45 foot Tug in the Army Reserve
(ST-2154) Time in 1975-1981 spent some cruises on FFGs and Destroyers. Got a tour of Trident Sub in DD at Banger WA.
LOL! :-)
Six minutes before even one reason for the "small holes." I gave up. Anybody have TLDR?
I only got to 3:30 or so then I momentarily lost consciousness
I've seen too many of these vids and gave up at 2 mins. Hoping a comment savior would have the answer or starting point.
I could not even watch that far ahead.
Hahahahahahahahaha
What’s your rating? “Small Hole Inspection and Treatment Petty Officer” or S.H.I.T. PO.
All ships have overboard discharges. Seawater is used for machinery cooling such as air conditioning, refrigeration, diesel engine cooling, just to name a few areas that use it. Also the CHT system goes overboard at sea.
Other areas needed for overboard discharges are in the scullery for the potable water overboard on the garbage grinder.
Seemed there was a lot of "repetition of information" phrases and content. Why?
To make the video longer, of course.
When you don't have much to say, say everything 3 or 4 times to fill up some time.
The non-stop babbling is because this channel is actually another outlet for Fluctus, which specializes in nonstop babbling and never giving any answers.
The hole that is made to drain water, drains water. Hoo yah.
1:26
It even drains SHIT . SO GROSS
The small guard "grids" over the small holes also serve as TIE DOWN POINTS for aircraft on the deck.
I build aircraft carriers at work. We been handling deck plates for Ford class carriers with the tie downs. We call them dimple plates. None that I've notice have had holes in them yet. Will keep an eye out for them now.
Those aren't drains, though. Just places for the crow's foot to attach to

@@offshorebear What does the X15 have to do with anything?!?
When channels will post videos like this that 17 minutes to explain what takes only less than a minute that’s whenever I block the channel
@8:03 & @ 9:11, These images present the operation of the Flight Deck Counter Measures Washdown System which IS intended to wash away any contamination or prevent the contact of any variety of sources before it can contact the surface of the ship>
I recall an aircraft carrier did this after contamination at Fuca Gima reactor meltdown and explosion of the coast of Japan..
Pumping/flooding voids with seawater to keep 4° list to port for landing craft.
The sea on recycle, keeping all safe.
Damn, this just goes on and on.
Poorly scripted video. I stopped watching.
The simplest and truest answer is Fire Main. You always have fire pumps running, as you use fire main water for other things than fire fighting, and you ALWAYS want fire main pressure. And since a centrifugal pumps needs water flow through it to avoid burning the pump up, you need to dump unused fire main water overboard.
Even if nothing else was in play, you'd have fire main water going overboard. But you do have water ingress into any ship or boat. So you always have bilge pumps. That and every ship i have ever seen generate water you need to get rid of.
Amen. Someone who knows what these discharge streams are for. The seawater inductions for cooling of the turbine generator and main engine condensers cooling loops are fan below the waterline.
Explanation is at 9:44, aircraft carriers need to expel ballast water, water used for cooling, and they generate waste water. All ships that people live on have systems like this, not just aircraft carriers. Did this really require a 17-minute+ video to explain? This should have been a short under 1 minute.
4:09-4:16 is all the 7 seconds you need out of this ass long video.
Some of the holes that release water is also water that is used to cool the shaft bearings that drive the wheels. Thes bearings need to be replaced and repacked a couple times a year. As a Deckhand and a Mate, I have had to help the maintenance engineer with this procedure many times. There are other areas of the vessel that are cooled by water as well.
Thanks for sharing!
It always amazes me that an aircraft carrier can stay upright. They look so top-heavy and are so much wider at the top than at the bottom.
I am also impressed how they are able to soap up the entire deck all at once, and then scrub it with a line of personnel with brooms to make it look squeaky clean!!!
When it drys you would never know there were any fuel spills, hydraulic oil spills, or aircraft lavatory spills (aka poop & pee and the chemicals that break them down to a liquid) ( if they even have lavs on military aircraft). Happens every day at every commercial airport…
So now, these degreasers have cleaned the decks and are washed overboard to feed the fragile sea life.
Ok, the degreasers broke the contaminants down to their molecular or semi-molecular components.
I don’t bang on the military for doing this!!! We need them to be at “Tip Top Condition” with the utmost of safety for our boys and girls….
But this shi! Goes on in the corporate world 100x worse!!
We don’t see commercial carriers doing this with no constrictions…
De-icing…(Snow/Ice Climates) - Spraying thousands of gallons of “Antifreeze” to clear snow and ice off commercial aircraft…Heated ethylene glycol mixed with water…
Where does it wind up after application???
In the ocean, streams, rivers, or maybe in the ground where it eventually gets into the water that wells we pump out of!!
Are we allowed to flush our auto cooling systems by letting them dump into the storm drains? No
I know I’ve gone beyond the aircraft carrier subject, sorry
Very informative. Aspects about aircraft carriers I hadn’t considered. Thanks.
Heat exchangers there are several
Cooling of systems and heat exchangers ....you welcome
you outdid yourself wonderful great stuff.
The Carl Vinson used to be my home away from home. 88 / 90.
At PSNS Bremerton?
I worked in Water Treatment before. It really is amazing. We would treat Acid and when we were done it was clean as water. If we had a larger waste treatment system we could have taken it further to where it could be put back into the lake.
Very interesting video.
Unlike a battleship, the aircraft carrier appears to have more structure above the waterline, and that the hull below the waterline appears 'narrow' by comparison. This has given me the feeling that the aircraft carrier it 'top heavy'. Yet, when seen making powered tight turns, they don't tip over. Seeing one in drydock, the lower hull profile doesn't look like the CG would be low enough to offset the huge mass above, even with a compensating ballast. Sort of the concept of an upside down iceberg. What are the physics going on here?
Thank you
wow amazing video footage explaining the daily care and maintenace of a modern aircraft carrier.
Drain off reactor cooling water? Stabilize the side to side rocking of the vessel? Drain for the dishwasher and chef functionaries in the mess deck. They feed thousands every day
I had a feeling that if I read the comments that I would find the answer faster than sitting through a mind numbing explanation as to why aircraft carriers exist.
generators, a/c, and excess bilge water are discharged through the small holes. Sea water is chilled and discharged for the ship's a/c system. The generators that produce electricity require sea water to flow through their heat exchangers as a means to cool them. Finally, excess water in the ship's bilge is discharged through the small holes.
3:33 answer starts-TLDR; carriers include seawater intake for cooling machinery & propulsion drives, ballast, desalination, etc. and these holes are the discharge and runoff
The proper adjective for the amount of space of the flight deck is not ample it is either minimal or barely sufficient.
Right. If it was ample it would be too big! A waste of money and a bigger target.
That was a very informative video. I pretty much knew why the holes were there and what came out of them but I did not realize it was that involved. I have one question what is the diameter of those holes they look pretty small, but that’s a very large ship, so they could be very large that was a very informative and great video. Thanks for sharing information with us.
Water on deck was never a serious problem. Most those holes were machinery cooling and shitter flushing.
Those tiny holes are for pumping out water leaking through all the bad welds.
Interesting info
Aircraft carriers before drones: Woof ! Woof !
Now? Quack ! Quack !
..
I've seen 2 videos of yours talking about carriers. In both cases, when you talked about the hanger deck. You've used footage of a Mountain Home AFB, 389th Thunderbolts F-15E Strike Eagle, which is NOT carrier-capable.
The voice of "What If" 🥳
These drain holes, need to have air pumps installed to make fizzy (aerated) water, and draining out, provides such ship-water friction-water interdiction. Having air bubbles along the ship's surface, reduces/removes water friction, allowing the ship to go faster without water resistance !!! Already other commerical cargo ships are doing this technology of a water slipstream, and the US military should be considering this technology for all large naval vessels, increased speed, increased maneuverabililty, and decreased fuel use.
The reference question was about the small holes just above the water line that is seen constantly ejecting water, not about the holes in the flight deck, or for the anchor, or in the bottom of the hull below the surface. I would guess that the holes along the side are for the ejection of ballast water which constantly accumulates in the hull, mostly because of condensation.
thanks. that wasn't addressed.
Scuppers.
I think i know all about the small hole now!
The handrails in the Engine Room are water cooled, so they have pumps to deliver sea water to the handrails where it takes the heat away and is pumped out thru those pipes you see in the thumbnail.
I didn't want a history lesson and a engineering class on design of the carrier.. Why are the damn holes on the sides of the ship constantly spueing out water!?!?
all that "water" coming out is from the bathrooms
Yes the small hole in some places can be used as aircraft tiedowns.
It's an aircraft carrier Sweat. When they reproduce they release Aircraft carrier eggs, that are fertilized by mermen. They make submarines that grow up into Aircraft Carriers. The Marines taught me that.
You tell Hasbro so they can make some for G.I Joe and Cobra, the terrorist group determine to rule the world.
Marines can communicate??!! I thought they just ate crayons, grunted and rode in Navy equipment…
There was no mention of "The Big Holes"... Must be a different video.
Small holes; decontamination.. Other holes (sea chests) reactor cooling (secondary loop).
Just curious, how many folks work on the flight deck? How many work maintenance, etc, to keep the ship working?
This video could have been a UA-cam short
i like openings
I have a great idea how to protect the u.s. naval submarines... if they build a "shield like" unmanned drones that with the right use of navigation technology that can simply follow around with the convoy and when ever needed these devices will come up and protect precious cargo and hardware while being cheap and disposable units readily available for access and action on every battle front. Hopefully this brilliant pop-up idea can be recognized and perfected as a totally functional concept for defense strategies.. idk maybe just my wild imagination 😅..
The propeller/screw shaft has a tight o ring seal inside ship but ALWAYS leaks water inside and must be bilge pumped out 24/7
This video is like watching paint dry 😟 Why do the holes have water coming out of them 🤔🤔🤔🤔🤔 I think you don’t know yourself !!
Then go watch a kangaroo mate.
What about copious amounts of water for cooling the Nuclear Reactor?
Maybe the captain has a spitoon or a hot tub? Bless our Vets 🇺🇸🇺🇸
The holes are the drains from the urinals on board.
Do Naval vessels still carry Marines on board?
Within the skin of the ship space cooling systems (heat exchange) produce a lot of condensation. Excess condensation is supposed to be drained outside the ship via dedicated plumbing which works unless some dumb ass wields the drain hole closed. This happened to one of my electrical shop spaces before getting underway and didn't get corrected until the next port visit when some deck ape could be put over the side to remove the plug. The whole compartment kept flooding and ships company told us it was our problem and to use buckets. 🤬
So, when I asked my Vice-Admiral father that same question...and he responded, "That's how it pees" ...he was just joking??? I mean...I was 32 but still.
Its called a bilge to get rid of seeping water
On the Russian carrier, they're constantly pumping the bottom couple of decks.
How is the sewage disposal handled?
Dam tha EPA
Yeah Right! How else do they flush!!
If it Ain't broke don't fix it !
Yes I know what the holes are for
Same reason in ALL boats
Waste water needs to be treated before discharge.
What does your history lesson have to do with the topic?
what are those long poles that stick out the side?
Antennas for communication
I suspect it has multiple purposes-: grey water sewage and cooling for multiple devices; on aircraft carriers, many things need cooling. Is it a nuclear-powered aircraft carrier? A nuclear reactor needs a lot of cooling.
Why don't you get to the point why the pumping of water.
❤❤❤
They are there to drain rainwater and ocean water splashes up onto the decks you're welcome
I think I'll google it!
All cooling.
fire supression;; decontamination (N/B/C)
The jbd (jet blast deflectors behind the cats are also water cooled. The water probably isn't recirculated but just seawater pumped through and right back overboard
Well DUH, it doesn't take a rocket scientist to figure out that the nuclear reactors and other equipment need constant cooling.
Thankfully we have rocket surgeons such as yourself to help us understand the sealed nuclear reactors have a closed pressurized system in order to avoid leaking contaminated radiated water into the ocean. Naturally, they may come a time when contaminated water might need to be discharged to avoid a meltdown, but at the moment, that has never occurred in a US Naval ship.
I suspect that water discharge is for non-fish killing purposes such as air-conditioning or fan rooms or bilge discharge or scullery (dishwashing) and mess deck & galley discharges and of course, discharging treated wastewater.
On the flight deck, the ship has the ability to de-contaminate the ship in case of Bio-Nuke-chem attacks as well as releasing AFFF Actuating Fire-fighting Foam to lay down a film that snuffs out the oxygen in a fire by creating an airtight film layer prohibiting fires from spreading. They use animal guts to create the foam. They mix it with sea-water at a ratio of 19:1
Class A fires - Water, Class B - AFFF, Class C - Kill the electricity, Class D - AFFF, CO2, Chem Powder, Class K - Halon, CO2, AFFF for grease fires.
Chemical Powder is highly corrosive. Water is good for cooling but doesn't mx well with electrical current. Water can spread fuel, oil or grease fires. Bad choice.
Who here has their Surface Warfare (SW) or Aviation Warfare (AW) device? If so, tell the internet why this occurs. While you’re at it, get me a yard of shoreline!
ESWS and EAWS qualified here! OS1 USN Retired
No clue what an AW or SW "device" is, but I once answered to both those callsigns. I guess I just assumed the entire boat was a big portable AW device with a lot of moving parts...
@@scottalanclymer AW and SW are short for Air Warfare and Surface Warfare. Enlisted Navy personnel can qualify as Enlisted Surface Warfare Specialist (ESWS) and/or Enlisted Air Warfare Specialist (EAWS).

17 minutes of video that could have been done in less than a minute.
So there would be a lot of human waste coming from those holes!
If war breaks out all these environmental concerns will quickly go by the wayside. Winning the battle takes priority over a "Greenie wieney's" rainbow and unicorns wet dream!
Those are bige pumps.
Yak, yak, yak!!
Water coolers
Because sailors drink a lot of beer!
NBC contaminent
Probable a cooling system of the reactors that powers the craft
A lot of the water that comes out of these wholes is used for cool in the ships aystems.
Engine cooling
There are a lot of people on an aircraft carrier that need to pee. You can't have that pee stinking up the ship can you?
Come to the point!!!!!
