What is a High Capacity Shell and Did New Jersey Carry High Explosive Rounds Too?

1. Hey everyone, this is GMG2 Jason R. Pribyl. I was on both west coast battleships (New Jersy, Missouri). When I went to gun school at Great Lakes, IL in early '88, the rounds were called "High capacity-High explosive" for the reason that Adam stated. they were essentially the same round, just a fuse difference. And so when I made it to the real navy (on a ship, the Jersey) the rounds were called both names together as above. Of course they were called HE or HC depending on who you were talking to but rarely if ever was the names said to designate fuse type.

2. DARPA came up with some really interesting rounds for the Iowas. There were the nuke rounds, of course, along with extended range rounds with 50-100 mile range & anti-infantry cluster munition rounds that could clear out an entire BTG in one shot.

   You can for A LOT of shit into a 16” battleship round. Now multiply that by 9 & figure 2 rounds per gun per minute…

3. "There's a fire in the powder room!"
   Air Force: LOL
   Navy: PANIC!

4. Thanks!

5. Air Force calls it a powder room….nice. Navy Gedunk

6. “Powder room”. That’s awesome.

7. Scuttle-butt for bubbler

8. Navy Sailors have troop ID cards.
   Airforce personnel have club cards.
   Army soldiers have material accompanying notes.

9. Scuttlebutt!

10. Air Force and 'powder room'…..as believable as that is, i feel that Ryan is poking fun at the AF…

11. All of the shells contained a high explosive charge. The HC just had more capacity for said explosive, but it still retained substantial armor penetration ability (Not enough for full thickness battleships but more than enough for most other vessel and vehicle armor, at 8 inches tempered steel or 10 feet of 5000psi concrete construction).
    A purely explosive round has much thinner walls and no substantial armor penetration relative to its size, its effect is purely from the explosion.

12. During Vietnam war sailors called massage parlors a "steam and cream".

13. I was wondering if you could shed light on the giant brass battleship mark up at the rest area on the Atlantic City Expressway thank you

14. Mark so that they don’t confuse with “M” numbers

15. Navel vs Air Force powder room.

    Navy to Air Force, no you can’t smoke while in the powder room.

    Air Force to Navy, wash your hands when done.

16. There were a ton of different HC rounds developed during the Iowas last commission beyond just the WW2 HC round. That would make a good video I think.

17. I’ve always been fond of OOC. When I was active Navy on subs, it meant “Out Of Commission”. We even put it on the “bug juice” dispenser on the mess deck. Anything not working go an OOC tag. Including some sailors who were not motivated to work hard.

18. Army, kitchen = mess , yea it sure is for some of the ones I've been in . Army , Limousin = any type of transportation. In my basic training our first ride in a Limousin was a cattle truck. A 20min ride to the rifle range. Army, bullet stop = a 11-b infantry. The list goes on and on

19. "High Explosive" is a technical term describing substances in which the combustion front travels through the material faster than the speed of sound (as opposed to "low explosives", in which the combustion front is subsonic). This supersonic combustion front results in a shock wave with a virtually instant rise in pressure, qualifying as a "detonation" in and of itself. In contrast, "low explosives" don't detonate – rather, they are used to pressurize a container, to the point of structural failure of that container, and it is this sudden catastrophic failure of the container that constitutes the actual detonation of a low-explosive shell.
    As a consequence, whereas a low-explosive absolutely needs a thick sturdy shell to create an explosion in the first place, high explosives need a shell casing only to maintain shape during firing, and maybe as raw material for shrapnel.
    So a high explosive allows for a higher capacity in terms of explosive material.

    Technically, a "high explosive shell" would be any shell that uses high explosives, regardless of whether or not it is designed for high capacity / low fragmentation. However, the term seems to have acquired the secondary meaning of a shell designed for maximum explosive yield, at the cost of fragmentation, which is exactly what high explosives excel at.
    On the other hand, similarly, technically a "high capacity shell" would be any shell that uses an unusually high capacity in therms of explosives, regardless of explosive type. However, this almost inevitably requires high explosives.

    In other words, in practice the designations "high capacity" and "high explosive" seem to be older and newer terms, respectively, for the same thing: A shell designed to give the bigest blast possible for the caliber, with negligible effect in terms of fragmentation. The former term is technically the more fitting (and at its time of use the only correct one), but has subsequently been superseded by the latter after its secondary meaning in this sense had already established itself.

20. Air Force, powder room, love it ????
    The largest rounds I handled were 5 inch when my GQ station was the 5 inch magazine on my first ship. 70 plus pounds of blue dummies, HE, AP, and Willie Pete. I don't recall any of them being called HC. But I could just be old and forgetful.
