0:30 Sturgeon class? Albacore class? I swear, underwater shots of submarines passing by make me giddy. So gad dang cool. That opening sequence of shots is flippin' mint. Maybe they're just practical models... but I don't think so. Thanks PeriscopeFilm! As always, amazing that you make this stuff available. I watch a few of these everyday.
Fr the sound of a sonar underwater is like 200dB. Kinda hard to believe that you can test that thing in air and it’s not loud at all, but underwater, it’s life threatening
Mk 84 is still in service, but not the Mod 0. Newer versions have 5 code settings, and the sea water activated battery is now in the nose section, with the electronic section in the rear. Battery is sealed with foil seals that rupture on impact, so the battery is environmentally sealed until use, this makes it far more reliable.
The Mk 64 was more fun. It was an explosive predecessor to the Mk 84. It contained 31.18 g of the explosive 2,4,6-Trinitrophenylmethylnitramine, commonly referred to as Tetryl. They had two depth settings. Tape a couple together and you got a submarines attention quick.
Surprising to see the axial-lead components mounted vertically above the board; I would think this would make the device sensitive to failures on water-entry shock/
Thing is, any smart Soviet commander would have known already that carrier battle groups don't go anywhere without a sub screen. This is a useful tool for rapid communication with subs supporting a surface group without waiting on a scheduled rise to periscope depth to copy the radio broadcast, especially if the pre-briefed signals correspond to useful commands like "come to PD and standby for further orders", "redeploy to fleet's flank", "sub detected within firing range of fleet, begin active search, locate, and neutralize", and so on. The surface groups already generate enough of an acoustic and electronic signature to announce its presence, even without active SONAR blasting away. If it's a lone-wolf attack sub operating on a detached mission, then yes, this would be an unnecessary risk.
I've chucked a couple of these from the SH-60B. Mostly, we just heard stories about our elders (our H-2 forefathers) peeing in them and putting them in toilets and swimming pools. Maybe that actually worked, maybe it didn't.
That IS NOT A SONOBUOY. I dropped hundreds of that little SUS bastards out of the P-3 freefall chute. Sonos are a five inch diameter about a yard long and have have hydrophones and transmitters to pinpoint underwater targets. SUS are explosive or non-explosive such as the MK 84 SUS. They are used to signal via sound. The first MK 84 has 4 signals, the later ones had five.
Can Your aircraft has dropped enough sonar buoys so that a man could walk from Greenland to Iceland to Scotland without getting his feet wet. Now, shall we dispense with the bull?
Another snap shot in time, both interesting and amusing, in an informative way. Thanks again Periscope Film, thumbs up 👍.

Permit (Thresher). These sail planes are almost on the top of the sail, its typical for that class.
the sound must drive the sea life crazy

That P-3 rotated like a boss @8:24
i buy things that still have that exact humidity indicator card.
Wow thanks sir! This very informative content

Hello my fellow MPRA people. P-8 guy here 😀

@@hoaxial2090How’s the maintenance on these? PITA?

Oh, I know why UA-cam suggested this old video now.
5:01 "DON'T HIT SUB" Honestly it would be most impressive if you did. They're not big targets for an aircraft, particularly one doing level bombing.
More chance of dropping into a whales blow hole then hitting a surfaced sub

Downside is that would tell the other side we have a sub in the area.......
Or at least let them think so...

I dunno, sounds pretty SUS
lololool
Heh heh. Nice!

What exactly do the sounds represent?
I'm more interested in what unauthorized items you've released from the freefall chute... Do people use it for disposing rubbish, and/or as a toilet?

One ping only please
Mmmm, bull dispensers.... Like PEZ, but rowdier.

A mk 84 is a gp bomb
I was an aircrew ordnanceman bullshit!
