btw. if that is too much water for you guys, some Army Merch came in today and I approved of the quality.

So sinking surface ships with torpedoes has nothing to do with armor/hull piercing munitions, but instead with the shockwave and "pocket" created in the water underneath the ship? So, torpedoes are just big high explosive bombs?


Guess you learn something new everyday, thanks MHV!

Great video, top explanation of a complex phenomenon - I reckon my brain expanded and contracted a couple of times while watching :).

[TheArmchairHistorian]

Absolutely fascinating, especially enjoyed the new graphics, and incorporation of scientific research.

Amount of quality and effort is evident. Excellent video

Key concept - air compressed easily, but “you can’t squeeze water”. Thus, the deeper the depth charge, the smaller the bubble created. Not to say that the blast front is lessened, but it dissipates faster and is moving 5x faster than it would in air

I know I read somewhere that in ww2 most sinkings from torpedoes are from flooding on one side causing it to capsize rather than breaking the keel

i have been learning about TBI and water explosions are the base of understanding the brain damage, so i appreciate your presentation, thank you

Modern Heavy Weight torpedos on SSNs and SSKs are a guaranteed kill on any surface target...Huge warheads with a deep terminal dive and its Endex...

[octasteve]

So, that's why depth charges work so well. Nifty stuff.

I came here to learn how the Korean vessel got sunk, thanks for explaining it.

I will still prefer torpedoes than mines.
Because mines are more like HE shells underwater and torpedoes are actually hard to recover once hit.
Because torpedoes also brings the water in the ship, and huge mass of water comes in at high speed, creating very little time to react.

It's just a little thing to emphasize: The efficiency of explosion in the depth decreases drastically, its power decreases proportionally with water pressure. So any submarine is safer in the deep depth, there must be the explosion much closer to be effective, than in lower depth.

[dextertreehorn]

A bubble can not "touch" the hull more than one time while "pulsating". It's simply impossible - think for yourself (The answer is in the question "why is the bubble pulsating?")

[johnyricco]

Given advances in active protection systems for tanks, one has to wonder how far such defenses against torpedos have developed under secrecy.

[MakeMeThinkAgain]

It's also worth noting that most of the energy of a bomb explosion on an armored deck or turret dissipates into the air whereas a near-miss can transmit more of the energy, through the water, to the hull or keel of the ship.

Also, under the heading English is nuts: "bow" rhymes with "Dow" not "Go."

[hllboi]

would the wsaer pressure 100s of meters down affect the radius of the shockwave tho, cause ud have higher pressure squeezing against the higher pressure of the charge and the water pressure, sonin theory the further down u go the more condensed the explosion

[gabszi]

You should do a video about Black Army of Hungary

[PsychoMan]

Are you going to do more division of hoi4?

It's "bow" like "cow"...not like a bow and arrow. In the word buoyancy the stress is on the first syllable.
