Few questions of my own

there is another thread where I answered these very same questions in detail so I will just summarize here.

Q) When Stingray is on quiet while Orlando is hunting them, surely Stingrays radar/sonar operative would not be able to hear coins falling and get it right, even if he could hear it, theres no way he could tell how much it was to the last cent.

A) What I enjoy about Down Periscope is that while comical and shown in an exagerated and fictional way, many of the tactics shown in the film are real.
This is a perfect example. Submariners do not wear the normal uniform boots most other navy sailors wear. they do wear soft rubber soled shoes. Modern military sonars are so good that non-natural sounds (called mechanical transients) can be heard from one sub to another. Now could sonar have heard and counted the exact coins dropped by the Orlando sailor? LMAO! No. Thats the fictionally exagerated comic bit. But a banged hatch, a dropped wrench, a pot dropped in the gally? Yes they could have heard it.


Q) Next, again when on silent, would the Orlando sonar really hear the fat fella farting in the galley?

A) Again see answer above. This is the same Q and A just with a different source noise. My answer is the same except to add that Low frequency sound travels a lot further without attenuation.

Q) What is a brushing incident? is it a collision with another vessel?

A) Yes. and it has happened in real life numerous times between US and Soviet subs.

Q)Can a Sub really be cloaked when hiding below a tanker, how does that work?

A) Gonna run out of time here but yes and no. Not in how it is shown on the movie but a contact on the same line of bearing as another contact can be masked by the louder contact until such range is achieved that the sub can seperate out the individual narrowband tone lines.

Q)I know the Stingray won the war game, but wouldn't the Stingray be sunk as the Orldando had a shooting solution, but Stingray had let off it's torpedos moments before.

A) yes it would have been sunk but think of the stingrays mission as a suicide mission, (Renegade sub) Even though they were sunk, they already fired their torpedo so they "Won" the mission even though they were killed.



I joined the Navy to see the world, only to discover the world is 2/3 water!

Just remember... this is a comedy!

Regarding the danger of transients - it's not a matter of "I just heard someone drop a pot in the galley" - it's just that it's an odd noise, and can indicate where to look harder.

Think about trying to find something making a noise in the basement at 2am. You stand absolutely still and just listen. Then you hear "something" - a rattle, a couple of taps, a little noise - you don't even know what you heard, but you heard it and you know where you heard it from. So you turn and head in that direction, still listening. You know where to look, which is a huge difference than just searching the whole basement.

It was a comedy. Everything was done for comedy effect. If this was done as a realistic movie it would be maybe the most boring movie ever made.
