The 102/35 su Fiat 634N was an emergency gun truck developed by the Italian army during the North African campaign; a total of seven were built.  The vehicles mounted 102mm 102/35 model 1914 cannons, taken from the Benghazi defensive battery, onto Fiat 634 trucks, the largest truck available to Italian forces at the time.  These cannons had served as the primary armaments of Italian destroyers and also as deck guns on Italian submarines during and after WWI, and after their retirement from naval service had been repurposed as anti-air guns.  The trucks were designed for multiple purposes; it was hoped that they would be effective tank destroyers, support artillery, and mobile anti-aircraft guns.  According to accounts the vehicles performed well in all of these roles; in the First Battle of Bir el Gubi, a group of five 102/35 su Fiat 634N trucks destroyed 15 British tanks from long range.  However, it was still an emergency design, and was plagued by multiple problems as a result, including a complete lack of armor, a gun shield, or crew protection, a high profile, poor off-road performance, and poor reliability (the weight of the cannon would wear out parts of the truck over time).  None survived the North African campaign, although one was captured by the British and photographed.

 

Reasons I'd like to see this vehicle in the game:  

-It has a larger cannon caliber than any gun truck currently in the game (current record-holder is the 8.8cm Flak 37 Sfl. flaktrack).

-It isn't going to be any more vulnerable than the YaG-10 (29-K), which is also an unarmored truck with a large cannon in the back (and despite its poor survivability is a good vehicle in my opinion, especially as a sniper).  

-Unlike the YaG, this vehicle can lower its gun and fire directly ahead (nothing is more annoying when driving the YaG than someone killing your driver, parking in your blind spot directly in front, and then leisurely slaughtering the rest of your crew).  

-Who doesn't want another naval cannon to use against tanks?  

-Most importantly, this vehicle provides something that Italy sorely lacks in tier 1-3 (where this gun truck would be placed):  a combination of one-hit kill potential with a 360-degree traverse.  Italy already has a ton of tank destroyers at this tier, but they're all casemates of some kind or another with poor traverse (both angle and speed), poor armor, and unimpressive reloads and post-penetration damage.  The cannon on this truck is more or less guaranteed to one-hit kill anything that it shoots, and it can cover a much wider area than the casemates can, which require a decent amount of time to turn the chassis towards a new target and then wait for the gun to settle on it.  It of course comes with a big downside, namely that the vehicle has absolutely no protection and can be eradicated with a one-second machine-gun spray across it.  However, it would be a long-range sniper vehicle capable of covering a large area and reacting quickly to threats.  I think the Italians could really use a vehicle like this and that it could shine with proper support.

I did.  I had to try this one, it's the most ridiculous of the gun trucks.  Biggest gun, least protection.

I have bad news about those vehicles...

1. The modified P26/40 turret was never installed on tanks;

2. The M13/40 with telemeter uses a fake wooden cannon;

3. I don't think the 149mm howitzer can really fire in such configuration... Unfortunately :D

 

Anyway, I think the 102/35 would be a great addition in the low tiers. It's slow and vulnerable, but at least it carries a very powerful gun to help the Italians dealing with Kv1, Char B1, Matilda and Churchill tanks.

I'd like to see this in game, as well as a mechanic where vehicles that need to be grounded can be grounded, to prevent transmission/engine damage. (Also engine damage if it's moving and shooting :P)

Hi @Milocat,

I'll add here everything that I found on the 102/35 su Fiat 634N, please, feel free to add anything that you deem usefull to your original post.

Hope this could be helpfull:)

 

BRIEF HISTORY (not that brief):

Spoiler

The history of the 102/35 begun in 1915, as an independent initiative by Ansaldo, which tried to convert a naval gun into a field gun, trying to cover the heavy demand of the Regio Esercito for a new heavy field gun.

 

This resulted, in 1915, in the birth of the first real “Autocannone” of the Regio Esercito, a 102/35 cannon, made to be equipped by destroyers, mounted on the chassis of the SPA 9000.

 

The machine was used, like every other autocannone until late 1941, as an anti-air battery piece, completely ignoring the great anti-tank capabilities of the gun.

The machine, being the first one of its kind, was filled with problems that compromised its performance , like the rear axle of the car being destroyed by the power of the 102/35 gun, and many thought that the 102/35 gun would never see any use outside of the naval scenario.

 

It was instead the Regia Marina itself, in 1941, that commissioned to the FIAT’s factory at Tripoli the construction of a new autocannone, built on the widely spread chassis of the FIAT 634N, that would mount the 102/35 piece on it.

 

The result was a highly mobile truck armed with a powerful naval gun, for which was also added a new anti-tank round.

Seven pieces of this machine were built and were then distributed between the 1st and the 6th batteries of the Milizia Marittima di Artiglieria (Maritime Artillery Militia) or MILMART ( 3 units to the 1st, 4 to the 6th).

 

Then the 1st battery and some units of the 6th battery where added to the “Ariete” armored division and, under it, the 102/35 pieces showed amazing performances in the battle of Bir el Gobi, where the great caliber of the gun and its high initial muzzle velocity granted it great long range performances, surprising the British troops, and claiming at least 15 medium tanks during the duration of the battle.

 

This performance inspired the Italian engineers to build the more iconic Autocannone 90/53 on Lancia 3Ro trying to match it.

 

As rapid and game changing was their creation, as rapid and brutal was their end.

By the end of the same 1941, of the 7 original machines, 5 were destroyed in intense bombing raids and 2 were abandoned due to mechanical failures, one of them being found by the British soldiers themselves, that also took some photos of it.

 

And so, because the 102/35 pieces were again deemed for naval use only, their story ended as quickly as it started, but not before inspiring what would be the most iconic gun trucks based on the 90/53 cannon.

ENGINE AND CHASSIS:

The chassis chosen for this machine was the one of the reliable Fiat 634N, powered by a Fiat 335C with 80Hp at 1700 rpm, capable of pushing it at 43Km/h on the road and around 18-20Km/h off-road.

The machine, due to the presence of the 102/35 cannon, had quite a big silhouette compared to its contemporaries in the Italian army, this made it an easy prey for allied bombers when they retaliated after the battle of Bir el Gobi.

Another note to add is that the machine, to maximize its effectiveness, sacrificed all its protection for firepower and mobility, this was made with the idea of quickly deploying the long range 102/35, when needed, in mind.

Here’s a picture of the chassis of the 634N:

And one of its engine:

THE CREW:

The machine had 6 crew in total, one drive, a co-driver, a commander, a gunner and 2 loaders.

The four crewmembers on the back of the vehicle usually sat on a makeshift bench near the ammo boxes, but here, they’ll be always manning the gun.

No protection was given to the crew by the machine, as it was initially created as a long range gun able to be rapidly deployed thanks to the truck on which it was mounted.

 

ARMAMENT AND AMMO:

Now for the gun.

 

MASSIVE EDIT IN THIS PART:

After talking with @_Condottiero_, @BlueBeta and @qwert96 it came to light that I misunderstood the ammunition part of this gun as I was searching infos about this machine.

The main mistake was misidentifing an old AA shell as an AP shell from another gun, making this gun more powerful than it was in real life.

Below I'll list the correct shells for it, with some new infos collected during that talk.

 

 

The guns mounted on those seven guntrucks were stripped, as an emergency measure, from the Tobruk defence system and some armored trains, where they were serving as anti-ship and heavy anti-air defences.

Because engeneers had no time to make major changes to this system it operated the same way as originally intended, as in an heavy AA cannon and a mobile heavy artillery piece on the battlefield.

 

Being it originally designed for naval combat the initial velocity of its pojectiles was quicker than standard artillery pieces in the italian army, this meant that the gun itself was both easier to man and more precise than its counterpart on the battlefield, leading to more direct or disabling hits.

 

The gun was mounted on a chandelier in the center of the vehicle, this granted a 360° of rotation on the horizontal axis and an elevation from -5° to 80° on the vertical axis and, to ensure this, the canopy of the cabin was removed during combat, to allow frontal and direct fire.

 

Problem quickly rose as soldiers noticed that the sustained fire of the gun was slowly breaking its own elevation mechanism and the chassis of the truck itself.

This was mostly due to the emergency nature of the system itself, that could not sustain long duration tests before being employed in the battlefield.

 

 

Here you can see the maximum elevation (the canopy here is not lowered because they were fighting bombers):

Spoiler

1060122535_maxelevazione.JPG.bb81cbc9272

 

As WWII came along this gun discarded its old WWI army shells to revert back to its navy rounds, only adding a new HE shell.

Those rounds were:

-a 13,750 Kg HE round, 1.3Kg of explosive mass, fired at 750m/s

-a 15Kg Shrapnel shell, time fused, 210g of explosive mass, fired at 750m/s (no more in production, in limited numbers)

-a 14,427Kg HE, unknown explosive mass, fired at 750m/s [1] (the new HE shell used by the army, this round also was in limited numbers)

With a rate of fire of 8 rounds per minute.

 

The ammunitions of the machine consisted in 20 rounds, stored in two separate ammo boxes of 10 rounds each on the back of the machine, here’s an image that can show it:

IN WAR THUNDER:

I think that the 102/35 su Fiat 634N could place itself at low Brs

That’s because, albeit not having any sort of protection, it still has a great amount of crewmembers (6) and an incredible long range gun

Mobility wise it will be a bit on the slow side, with only 43K/h on road and 18-20Km/h Off-road, but its main playstyle would not be similar to a frontline tank, but instead more similar to a long-range artillery, as it did in real life.

Some may already have recognized it, maybe those brave pilots (and by brave, I mean completely crazy) that brought the Piaggio P.108A in ground battles, as the gun on the Autocannone 102/35 su Fiat 634N is the sister gun of the one on that machine.

The gun was mounted on a chandelier in the center of the vehicle, this granted a 360° of rotation on the horizontal axis and an elevation from -5° to 80° on the vertical axis and, to ensure this, the canopy of the cabin was removed during combat, to allow frontal and direct fire.

The gun was able to fire three types of ammunition:

-a 13,750 Kg HE round, 690g of explosive mass, fired at 650m/s [1]

-a 15Kg APHE, 80g of explosive mass, fired at 750m/s [2]

-a 14,650Kg Shrapnel round, unknown explosive mass, fired at 650m/s [1] (not used during WWII)

With a rate of fire of 7 rounds per minute.

The gun was considered extremely powerful by the Italian standards, almost competing with the famous German 88mm, being able to easily punch trough 100mm of armor at 500m.

The great performance of the gun, coupled with the fact that the 102/35 pieces were only provided to the MILMART in limited numbers (only 7), pushed the Regio Esercito to study new types of autocannone, bringing the 90/53 to life.

IN WAR THUNDER:

I think that the 102/35 su Fiat 634N could place itself at Br 3.3, right below the Semovente 90/53 M41.

That’s because, albeit not having any sort of protection, it still has a great amount of crewmembers (6) and an incredible long range gun, capable of facing any threat without fear of not penetrating its target.

Mobility wise it will be a bit on the slow side, with only 43K/h on road and 18-20Km/h Off-road, but its main playstyle would not be similar to a frontline tank, but instead more similar to a long-range sniper, as it did in real life.

yes. this is going to be a very good tank destroyer. 

weighing 7.9 tons and have an 80hp engine, means similar mobility performance to the ZiS-12 (94-KM) [7tons with 70hp] but with a lower top speed.

 

due to better mobility, better firing angles and better armour penetration then the YaG-10 (29-K) [BR 3.7] with only a potentially slower reload to counter these advantages I think it would be BR 3.7 minimum.

 

but its a +1 from me

That's an impressive top speed, but is it simply on paved roads? Also, what's the gun traverse speed on this thing? It looks quite heavy. Finally, I'd like to know the penetration stats of the gun/ammo.

 

I am leaning toward yes, but the first two issues might be make-or-break when it comes to trying to move around on snowy, muddy or hilly maps.

According to what I've read, offroad performance suffered significantly, which was a major flaw of the vehicle.  According to a source posted by Taffu92, the offroad speed is about 18-20kmh.  

 

The traverse speed would have to be quite slow, since I'm certain that the gun is hand-traversed.  I never saw any note of a mechanical traverse in the sources or any sign of it in the pictures and that would pile even more weight on the truck.  

 

As for penetration, I didn't find any sources with a specific number, but again according to Taffu92's source the APHE shell weighs 15kg, has 80g of explosives, and is fired at 750m/s.  According to this calculator (  Tank Archives: Penetration Calculator ) that offers a maximum penetration of 120mm.

Wow. 120mm seems...pretty unimpressive for a 100mm APHE shell. Hopefully some more documents surface on it.

 

Maybe it wouldn't be so bad on flatter maps and at a lower BR. Probably lower than the YaG-10 (29-K). So...3.0 tops, I guess, particularly since something even larger than the YaG-10 would be completely destroyed by post-Overpressure HE. But at least its own 100mm HE will allow it to give as good as it gets in that department. The verdict is a cautious yes from me.

The traverse speed would have to be quite slow, since I'm certain that the gun is hand-traversed.  I never saw any note of a mechanical traverse in the sources or any sign of it in the pictures and that would pile even more weight on the truck.

Hi, here to answer some doubts:)

 

Yes, traverse speed will be a bit slow (but not that bad as some diaries says that it was quite easy to put on target) as the gun was hand-cranked. This was a necessary solution as the machine was really riding on the edge of its maximum weight due to the installation of a naval cannon on a truck chassis (even if that chassis was quite impressive itself)

Non the less there are multiple reports that even those few guntruck suffered heavily due to the sheer force of the gun, one of them litterally snapping the entire rear section after firing for a prolonged time.

 

Mobility wise it won't shine off road, even there there are are reports of it being quite slow compared to other machines and its size made it quite an easy target.

 

Penetration wise you can find the same gun that it uses on the Piaggio 108A in the italian TT, if they keep the same penetration values it should have around 140mm of pen point blank.

Official sources of its performance against armored targets are really scarce, as the machine was literally an improvised solution to boost firepower on the frontline.

In another report it's said that, quoted "the gun was able to easily neutralize armored british tanks armed with 40mm guns at distances around 1 to 2Km".

As you can see the report is pretty vague, but we know that those guntruck were built in late 1941 to counter a new british threat that standard 47mm in the italian army could not face, so.....maybe they're referring to Matildas? (as they appeared in the african theater in 1941)

 

Still, as only 7 of them were build and were all lost due to heavy british bombing (as retaliation to the losses caused by those guns) or self destroyed by italian soldiers we don't really have extensive trials o test reports, they had an extremely short life and we are really lucky that both italian and british soldiers had the right idea to, at least, whrite some reports and snap some photos of them.

Santo cielo, I remember seeing that plane in action. I hope it's easier to hit targets with this truck; it'll be nice to have a vehicle that makes the 102mm gun enjoyable to use. The recoil will probably be something to behold.
