Title: M4 Firefly?
Post by: StokesAk on July 26, 2010, 03:30:35 PM
Why is it 20 perks when the gun on it sucks and it can get 1 hit by any tank from any angle?

The new M4A3(76)W is better that thing should have more of a perk.

Don't have the details in front of me, but if memory serves that 17lb gun on the Firefly is superior to the 76mm on M4A3(76)

*edit*
I was able to jump in game real quick and check the numbers,

The Firefly fires at 2900 ft/sec and can penetrate 178mm of armor at muzzle velocity and 0 degrees.  The Sherman 76mm comes in at 2600 ft/sec and 134mm.

I will take a Firefly in a stand up fight anyday.  The 17lber just hits a heck of a lot harder than the 76mm.

Stokes, the M4A4 (what the firefly was converted from IIRC) didn't have the wet storage. It was more prone to lighting up than the M4A3(76)W was.

And the 17lber is a great gun. Its even better than the tiger's at short-med range (of course the Tiger's gun is already overkill). At long range, the '88 out preforms the 17lber because it has more mas to maintain its kenetic energy.

The Firefly was converted from any type that would fit the 17 pounder (M4, M4 Hybrid, M4A3 and M4A4) while the M4A1, M4A2 and M4A6 were found to be completely unsuitable for use with the 17 pounder.  Depending on which variant was used and whether or not that variant delivered to the British was produced with the dry or wet stowage dictated whether or not that Firefly had wet stowage or not.  For example, if the Brits received some M4A4s or M4A3s that had dry stowage then that's how that Firefly was, if the tanks were delivered with wet stowage hulls, then that's what that Firefly had.

The Sherman VC "Firefly" has the same hull as the M4A3's, but it has a much harder hitting gun albeit a slower reload.  In a long range fight, only the Tiger can trump it and that is because mainly the Tiger has the armor to absorb some of the damage with the Firefly does not. 

The firefly is truly a beast and should not be used for anything other than a long range tank battle.

For what it's worth,  Mark Hayward's book on the Sherman Firefly, which is very good, says that despite some claims to the contrary, only M4, M4 Hybrids and M4A4s were converted to carry the 17 pounder.  No M4A3s were converted as the British only got seven total M4A3.

When I was searching around looking at different tank model kits, I stumbed onto this one that was a model of a US M4A3 Firefly, was going to dismiss it as a "what if" tank until I saw the name of the builder and read the captions.

Nice catch AKAK :)

The book is still a worthwhile addition with lots of photos and detail drawings.  I have Zaloga's early Osprey book on the Sherman.  His name is a familiar one.

Thanks for the link to Hayward's site too!

Interesting to note that the US conversions never saw combat.  Wonder if any are rusting away somewhere in the US. 

I have a half started Dragon 1/35th scale Firefly that's been sitting waiting to get finished for the last dozen years or so.  Got the turret done but this computer flying stuff always seemed to drag me away :)

I believe the individual you and I got into a discussion on whether or not any of the 76mm Shermans landed at the beaches on Normandy wasn't a big fan of Zaloga.  Of course that was probably because Zaloga's work showed this particular individual to be incorrect.

Because the US was already working on the M26 Pershing and felt the 90mm tank gun was just as effective as the 17 pounder.

actually, they are correct. Granted they give the maximum velocity and armor penetration the gun is capable of, not the measurments at combat ranges.

Maybe on paper, Most of those values are taken when compared everyone elses armour but the Germans. The Brits actually tested many guns on an abandoned tiger and found out just how over matched they where. I think it was in Tunisia, I'll check my books. A table I have uses the average results, that the 76mm M1A1  needed to get within 700m to penetrate the weakest of a tigers frontal armour. The 75mm had no successfull frontal armour penetrations and had to be within 100m to penetrate the 80mm side armour of the tiger. The 17lber worked at most ranges that the tiger could kill it at. As far as using IL2's on a tigers turret top and engine lid, after march 1944, they increased the armour from 25mm to 40mm. Do the math on the IL2's 37mm.  T/d,  40/37 the armour thickness over matches the diameter of the cannon, so these 1 pass tiger kills, to me anyway, are all fantasy (in the late war arenas anyway).

Im not so sure about the situations where the lone N1K1 flys by and does the oblique strafe and the tigers track just falls off and the tank lurches over on its side. Yeah right. Pull up some photos of a tiger track and see just how thick the plating is and how its hinged together. More fantasy IMO.  Unless the tank is moving, its not going to shed the track and keel over to one side even if a link is broken. I know its just a game, but man, could at least have a goal of 50%  reality. Everone should read the stories of these tiger tank commanders. Most of them sound the same.
Title: Re: M4 Firefly?
Post by: Nemisis on July 29, 2010, 04:41:20 PM
well Jamdive, seeing as the tiger is avaliable in MW, then we must have the tiger with the 25mm armor.


And how many 20mm rds do you think it would take to sever one of the connecters? The niki has 4x 20mm's, what is the ROF for them? And how many rds will hit the track assuming a 3 second burst?
Title: Re: M4 Firefly?
Post by: BigKev03 on July 29, 2010, 05:23:08 PM
I think the perks for the Firefly are due to the gun capability more than anything.  The armor on the Firelfy is slightly better on the turret but other than that it is what an average sherman would have.  But that 17lb gun is very good.  Though as another poster stated at longer ranges it does lose its kinetic energry faster than the 88mm but it still is a dangerous gun and has to be repsected.  I think the perks are about right.

If the convergence is perfect, and if the point of impact is exactly where it needs to be, and if there are multiple hits on the exact point of the weakest part of the track... then yes.  But, imo... a bunch of 20mm HE rounds, regardless of where they hit, should be of little concern for any tank in the game.  The worst should be the loss of the top MG and some scraped up paint.  The .50 BMG rounds, when massed, and when impacting on the top of the engine compartment or weakest part of the track should have far more capability to harm a tank than most any air to ground HE in AH.

Post by: Nemisis on July 29, 2010, 08:46:59 PM
Loon, while that is true, we have players emptying their guns at tanks (I've even had my tiger strafed by a Spit I), rearming, and doing it some more. While I think its more an act of defiance and a release of frustration than a serious attempt to damage them, with all those bullets hitting the tracks, someone is going to score a lucky hit.


As to the .50's damaging lightly armored components of a vehicle, I think the reason we can't is that compounding damage to the armor from rounds that failed to penetrate isn't modled (15mm of armor plate may stop a .50, but can the weakened and thinned armor (it will likely create a dent, which means the metal must strech, making in thinner) stop the second round, or the 3rd round?). Personally, i would love to see this modeled upto a point (the M8 shouldn't kill a tiger regardless of how many rounds are fired).

So your saying a 20mm round can penetrate a 56mm steel plate and then break a 28mm pin after it some how went through a 1/2" track guard?  Whats a 20mm good for? On a good day and a perfectly flat shot at 100m or less maybe 25-27mm of plate steel. Where do you think your goin to get a perpedicular hit on the track? Even with the wide combat tracks there is very little track exposed. Even if a wheel is knocked off it still has 2 more per axil and would still be able to move. I seriously doubt youd get multiple rounds hitting in the exact same spot diving in with an airplane on a strafe to support your theory that the cannon will just bore a hole with multiple hits.

427 of the 1,349 Tigers produced were made between March 1944 and August 1944, when production shut down. So, the 40 mm roof armour applies to less than a third of Tigers made.

The NS-37 used the IL-2 was tested as good for 48 mm / 500 m / 90 degrees. Source is Tony Williams: http://www.quarry.nildram.co.uk/tankbusters.htm

Another figure I've seen published quotes 52 mm/ 200 m / 90 degrees.

Muzzle velocity is typically quoted at 880-900 m/sec.
 
Add an extra 85-100 m/sec from an Il-2 doing 300-350 kph and this adds up to quite a formidable round.

First of all, you have to be carfull when looking up production numbers on the tigers. Every time there was an update, such as a new track system, gun sight, retro-fitting, ect. they counted that as a new tiger produced in some tables. More more readings, (if your really interested in actualities) look up some of the data on the percent of tigers operational vs. the panzers. Its the same if not better. The tiger, dispite its weight, could operate on softer terrain than most tanks. When looking up the armour thicknesses, youll see one of the thin hull armour displayed. Dont forget to add 25mm x 3 for the number of interlaced bogie wheels. There is also very little clearance to allow a shell to actually hit the turret ring. The round would be halved by the time in made it to the ring. Allied shells also had a problem of being to soft, at certain high velocities the shells would shatter instead of sticking to the target and making penetration. If you dont belive me on this, fire a 30-06 at a tub of water and see if it makes it out the other side, then do the same with a 12ga. slug and compare the results. Same principal. Ive contacted my friend who is history major for the civil war and WWII in Virginia to see if he has any actual data on what these weapons did vs. the calculations of some twidget with a slide rule. Reading some of these tank commanders memoirs, these tables and the actual accounts are in large conflict.

OK Jamdive, let me put it this way: Realism has to take a back seat to game play.

Either convince HTC to make the VH's require 6000lbs of ord to destroy, make it so killing ammo bunkers only cuts the ord you can take in half, or accept that (for reasons of game play) planes NEED to be able to track tanks.

for your tiger thing: since they are avalable in MW, then clearly we don't have the tigers with the increased top armor or any of the modifications made after '43.

And based on your comment about the tigers armor being thicker than the diamater of the Il-2's gun, it seems you think that armor penetration is based on the gun's caliber. Clearly that isn't so, other wise the '88 couldn't penetrate more than 88mm. I don't care if you have 70mm of armor, if you get a 37mm round going fast enough, then it will punch through that armor.
