Can't think what else the royal canadian artillery would use that looks like that other than a priest.

E: Wait, no, looks more like a sexton: It's missing the ridges around the vision slots for carrying stuff and the gun's on the wrong side, also no MG cupola. And it's got that sticky out bit in the middle around the gun.

There's a good reason BB shells had so much other *stuff* in them instead of additional explosive - it was needed to punch through the armor plate. Mortars and HE artillery rounds often had significantly more explosive power then the best antiship shells.

While I don't know a whole lot about modern antiship missiles (or torpedoes which I'd imagine are pretty potent now) I'd love to hear about it! I've got to imagine they're either using incredible velocity or HEAT shaped charges.

Bear in mind that armor (designed to resist the high-velocity kinetic forces induced by a shell impact) tends to be brittle under explosive loading. You see this being a problem sometimes during WWII with torpedo impacts, as in the case of HMS Indomitable: An Italian aerial torpedo struck at the bottom of the side armor, pieces of which broke off and passed through the torpedo protection system and into a boiler room.

Wasn't there also one tank design that had two machine guns fixed directly to the front hull with no traverse in any direction whatsoever? That's downright orky, just spraying bullets in the general cardinal direction of the enemy.

Yeah, the M2 light tank and early versions of M3 Stuart did this. 5 machineguns altogether.

M2 Medium Tank however had nine machineguns, including two rear-facing machineguns with deflector plates so that when the tank would cross trenches the bullets would be deflected down. I suspect this tank was designed by Browning Arms Company to boost sales.

Subsurface explosive effects are extremely different (and quite a bit more destructive than) explosive effects in air.

The strv m/42 originally had a forward facing hull machine gun mounted to the right of the driver, where the radio operator in a Panther would sit. Except... there was no such crew member in the m/42. It's just a machine gun with nobody there to fire it - there's not even a seat for it, the only thing under it is an ammo rack. To fire it, either the loader has to slide down from the turret and lean over the ammo rack, or the driver has to lean way over from his seat to handle it.

As far as I can tell from minutes of meeting it was concluded that the tank should have four machine guns, and that a hull machine gun had been useful on the WW1 era strv m/21-29, but that adding a fifth crew member would add at least another 100 kg to the tank, and their strict weight budget didn't allow for that. So... they voted on it and said yes, it should have four machine guns, and four crew members. And there it went, four machine guns it had when it was delivered (the fourth one is pointing backwards in the turret). The hull MG was rarely mounted on field exercises though and it disappeared entirely within a few years, and the port where it had been was welded over.

Considering that the thing was basically designed by cargo culting committee in a few months in 1941 it actually turned out surprisingly well, but you still got a few oddball issues like this one.

By "other stuff" you mean hardened steel -- a 2700-pound AP shell was 98% hardened steel, a sheetmetal aerodynamic cover, a soft steel nosecap, and 50lb of RDX.

And it's moving at about the speed of a .30-cal rifle bullet. That's 355Mj muzzle energy. I can't easily find a comparison, but y'know how TV shows frame things in car crash equivalents? It's like a smallish car going 1700mph. The bursting charge is just a "gently caress you" afterthought once it lodges inside the ship.

For comparison, HMS Victory's entire broadside was about half the weight of one shell from a 16" gun.

Cliff notes (:v:) of the story is the RN were having a tiff with France (something about Napoleon but frankly like the RN needs an excuse to shoot the French) near Martinique. Diamond rock sits off the coast at the western arm of the large southern bay of the island and overlooks the strait between Martinique and St Lucia.

The RN sends a fella by the name of Commodore Hood to blockade the place and generally annoy the French, again not entirely sure the Napoleonic wars were necessary for this but supposedly that's the rationale they used. So Hood sails about in his ship Centaur generally being a dick. He's visiting the rock because it's got some greens that the crew can eat to keep the scurvy away and eventually decides to lug a pair of 18lb cannons up onto the rock and fortify it. He commissions it as a sloop of war and assigns his second lieutenant to command it. They also stick a few 24lb cannons in caves around the rock and basically decide to pre-enact the movie Guns of Navarone, shooting up anything passing between the rock and Martinique proper, and using the high elevation of the rock to take potshots at anything that tries to get near them from the south.

Having fortified the rock and stashed a good amount of supplies on it (including some goats) he writes to the admiralty telling them about his awesome new "ship" and it basically becomes a thorn in French-controlled Martinique's side for about 18 months, as it makes it a right pain in the arse to get around the south side of the island. The French try to set up a mortar battery on Martinique to shell the poo poo out of the rock, but a group of slaves tells the garrison about it, they lead a sortie out and capture the only engineer on the island so that never happens.

Eventually, French high command gets really sick of this bullshit and sends 16 ships out to get the drat rock back. Alas, the actual battle also goes rather like the Guns of Navarone in that the French assault goes pretty well because the garrison runs out of ammo and water very quickly and surrenders. Also they had 16 ships blowing the crap out of the rock as well.

The guy in charge of the rock is court martialed for "losing his ship to the enemy" but they acquit him on the grounds that it's fairly reasonable to lose 16 to 1.

All in all the French didn't try much to attack the place and when they finally took it they mostly did so by besieging it. It's more funny for the idea of a rock being treated like a ship than anything though the RN does this sort of by habit with a lot of their land installations. Though as the RN also once upon a time did a lot of their home operations on hulked ships moored permanently in port that does make a certain sense, they just kept their names when they moved them onto land, and it saved on updating the legislation too.

But the court martial didn't acquit one of the other officers for the unforgivable act of eating a meal with the ship's company rather than in the 'wardroom' (a tent a few yards away). He was reprimanded but his field promotion to lieutenant was substantiated and he was later given command of a brig so there was some leniancy.

RN ships passing Diamond Rock still dip their ensigns and man the sides in salute to this day. I'm pretty sure the rock is no longer considered 'in comission' these days, though.
