How long ago are we talking for Old Fashioned? I was a midshipman starting in '06 (unable to commission for medical) and definitely learned it as conning tower from the LT.

Which navy? I’m not fussed, but conning tower was when there was an chamber in it for the conn

U.S. College program midshipman at U of SC.

And that LT served on boomers.

Interesting Was ‘sail’ also used on your submarine?

Not that I recall.

In 1950s when USN & RN started streamlining it they switched terminology to sail/fin, partly to emphasize the change I think

Curious, in spanish, the word "kiosco" or "quiosco" is used when refering to newsstand/paper shop business

Kiosque in french is a little structure. You can find them in public gardens where some musicians can play for instance. It is also a little structure where people sell stuff (newspaper, flower, whatever). And the submarine's top structures. (But I'm not sure while it would sound old fashion 😅)

Here in spain "kiosko" means the same for 2 of the 3 cases, for the submarine top structure, is called the "vela" (sail) of the submarine.

The Spanish choice might simply be because after WW2 they got subs from America before later adopting French subs

In Swedish it is, as far as I understand, "torn" i.e. tower or turret.

35. Anyone who wants to seriously argue, or worse belittle others, based on the use of these terms is a plank and best avoided

Isn't it tragic how no WW1 submarines survive? Those boats had real conning towers. I mean, U-1, but that was a training boat only, already obsolete in 1914. Kerosene-powered attack submarine...

Yes See post .38

36. LNG tankers are probably a lot harder to blow up than most people imagine (Admittedly I’ve never tried)

I'd guess the second torpedo hit would do the job. The first opens a tank and aerates the gas, the second ignites it. If this is a scenario, there is probably also a time component, as you need sufficient time for the gas to deliquefy.

Then again, liquid gas is heavier than air, so normal ship destruction processes apply. Open a hole big enough underwater in the hull and normal fluid dynamics start doing their thing. (This is an interesting question. I'm at least one navy has researched it.)

37. The holy hand grenade of Antioch, only bigger

38. The German UC-1 and follow-on UC-2 classes were the most successful submarines ever, but they are largely forgotten. They sunk ships by laying mines.

Mines are just underrated in general. There's a reason we Aussies keep a decent stockpile of Stonefish around.

The Germans didn't really go for (the smaller) sub minelayers in WW2. Any idea why? Maritime patrol aircraft? Payload considered too small? Focus on convoys?

39. The Soviet Ushakov flying submarine was a terrible idea. Only famous for fanboy reasons

Now that is something I would have drawn as a kid.

40. The VA-111 Shkval rocket powered supercavitating torpedo is much overrated. It’s interesting but nowhere near the superweapon the internet makes out

Could you please elaborate about that ? I heard it was fast but very noisy and nearly impossible to change direction. That once fired and despite being fast, targets could nevertheless evade it if quick enough. Is that it ?

It is supposed to work as a self-defense weapon: Russian sub hears enemy sub firing torpedoes and fires much faster Shkval at it in response. Noise is irrelevant in this scenario, since the enemy already knows the location. But how/if this can work in practice, is a really good question.

No direction change : can only be useful at short range, no ?

I read about it having some sort of terminal guidance, but I have no idea how can this work in practice. As originally conceived it had a small nuclear warhead and this version could be practical.

Are they available in a conventional version, or only with a nuclear warhead?

41. The Royal Navy's Coastal Motor Boats (CMB) from WW1 were incredible works of art. See a beautiful replica at Boathouse 4, Portsmouth.

Stunning! 😮

42. The WP-18 interceptor is probably the fastest naval vessel (some claim faster but.. ) speed 65 knots +

43. Interceptor boats built by Irish company Safe Haven Marine are also wicked quick, but they are also specialised for particularly heavy seas. If they roll over, they self-right.

👀

44. Admiral Sir Sidney Smith is the forgotten British hero of the Napoleonic Wars. A contemporary (and sometimes rival, later friend) of Nelson, he deserves far greater recognition than he gets (or got at the time, at least by the establishment who largely resented his conspicuous success).

Are we talking current or historical? SES-100B hit at least 75 knots (wiki says 96 knots in trials, but doesn't source that).

oops
