B-25H Cannon's ROF
#16

Now that I think about it, I can't see why the loader couldn't pull the next round out of the rack as the gun was firing, or at least already be reaching for it.

Well, he very well could. Thats what I've referred to as "Lap-loading". Briefly:

Crews in tanks that have ammunition stored in blast bunkers, such as that Abrams loader, do not lap-load. If the ammo goes off it will simply blow the top of the bunker off, unless you're holding it in the turret with you. The 120mm ammunition seen there also has a combustible case, which you won't want to hold where it can be ignited.

However, crews in tanks without blast bunkers, or in vehicles (or aircraft) with brass cased rounds, will probably lap-load. You've got no added risk by lap-loading but maybe getting that second shot off that much faster will keep you alive...

it took 7-8 sec.to load the 75mm but with only 6-8 rounds thay liked to fire it slower only win on target

I have been browsing for some of internal pictures of B-25s with 75mm inside to give all of you better idea of what its like being inside hull of B-25s gunship.

I'd like to know where your information comes from, because we already know that they carried more than eight rounds.

hello... Mr. Modder... are you out there?

recalling from a book I read, the firing procedure invloved getting out of the way of the shell ejecting against a peice of wood. It seems it was also quite smoky, and after a few runs, he was ankle deep in shell casings.

The chapter of the book in which this was written by a B-25H pilot, so I assume he knew what was going on, even if he wasn't the loader.

He also said that it was very bouncy in the aircraft, maneuvering on the deck.

It would seem to me, that although it would be possible, and likely for the gun to be loaded faster than 12 seconds a round, the 12 seconds a round is not unreasonable as a safe time.

However, even if it would be realistic, i don't think anyone is allowed to change the reload time.

I would really like to know how many of you guys have done anything under duress! Let alone that stress include death.

Here we are talking utter chaos an extremely stressful environment!

-You are being tossed around in an aircraft that's maneuvering to evade enemy fire in a close confined area.
-There is smoke in the cockpit from firing weapons and the buffeting from that as well added the smell of anything that might be burning at the time.

Not even close.

You guys might want to consider reading the evidence presented before commenting.

I'm with idonno on his. I would definitely like to see new slot B-25G and B-25H new slot planes with corrected 75mm rof. I thought I read somewhere about 12rpm was the practical rate, but I've been unable to confirm this. It's not like correcting the rof is going to make the plane uber or something. The film "Winged Artillery" seems to show variable rof, I don't have a stopwatch, but one B-25G appears to fire 2 rounds 6 or 7 seconds apart during one sequence. Same film also shows B-25G's with early style field-mod twin 50cal blisters each side of the cockpit.

Good points from all who posted here..

but, changing the ROF on this cannon would only cause more discussion and highly probable; more disagreement.

The thing is:
The cannon was handloaded. A ROF of 12 secs would be about the max it should take.
I can imagine that in a confined space of the B-25, under highly stressfull combat conditions, as a loader, i'd be slamming shells into the cannon as fast as i could.
(bet any loader would do so).
But in the meanwhile you're rocked because of turbulence - flakburst turbulence, the aircraft is possibly hit, it also moves to dodge incoming fire.

All that just adds up to the stress.

So, a ROF of calculated 3-4 secs, seems way to high for me, even with the loader lap-loading, it seems high.
Thus I assume that 3-4 secs is under ideal conditions.

Then again, remember; the cannon was hand loaded. Lots of things could go wrong, slowing the process down.
Therefore, i assume a reload time (minus possible cannon jamming etc.) would be somewhere between 6-10 secs, a variable, with 12 being the max and 4-5 being the fastest time.

It would be most/more realistic, if such a variable reload time could be coded into the game, but I guess it can't.
