The Italian Guns.

[CharlesBronson]

I find one image of the Breda 37mm gun.

In Fiat Cansa FC 20 ter. The gun is laying in a side in order to be feed from above.



Quite impressive isnt ?

Ansaldo 102mm/40.



In late 1942 the Regia Aeronautica began to explore using its larger bomber, the Piaggio P-108B as a long rance maritime recce and attack aircraft, much like the way as the Fw 200 employment in the Luftwaffe.

For that task several types of armament were tested in this aircraft, including radio controlled topredos and armor piercing bombs. However the closeness to enemy Flak remained as a problem. An alternative to attack transport ships and destroyed was to employ heavy artillery piece.

Originally a 75 mm antitank cannon was to be used, but eventually the heavier 102mm was selected to arm the P-108A ( A for artigliere, artilleryman)

The Ansaldo fist tested the gun in ground shooting inside a mock up nose in october 1942.
In april 1943 2 P-108A were ready for test.

Ansaldo`s 102mm howitzer was emplaced in a solid nose aimed by the copilot with a Reflex San Giorgio gunsight with a line of fire tangent up to 4000 meters. It had weight of 680 kg, and was manually loaded from a revolving ammunition dispenser of 6 rounds. A total of 53 round could be carried in the frontal section of the aircraft, the complete gun ad related devices/ammunition weight over 1500 kilos. Some minor damage to the nose section forced to use a steel sheet to protect the structure from the muzzle blast.

The Piaggio P-108A was tested intensively until september 1943, the 4000 meters range was saw as excesive and most of the shots were carried out at 1500 metes for better view of the target. there is no information if this type entered in action. One was captured by the Luftwaffe and tested as well in Rechlin in early 1944.

I forgot to mention that the muzzle velocity of the 44 calibres 102 mm gun was 700mps. Armor penetration with apc projectile 165 mm @ 500 meters.

Are you sure about the 102/44 gun? If you have a look here then Tony Williams identifies it as a 102/35 weapon.

[CharlesBronson]

Nice picture ! I made a mistake when i put "44" it is a 40 caliber gun.

Not sure about Tony information, maybe the barrel was shortened a bit to be emplaced in the bomber.

[Vincenzo]

Italian measurament of barrel was different form germans i don't know for others standard

[CharlesBronson]

Teorically the usual measurement included the chamber.

More pictures of the Breda S.A.F.A.T 7,7 in manually operated double and single mountings.

This is a great thread and all those ordnance stickies are great too!
I can offer just one little correction:

I'm affraid that isn't so. Breda SAFAT and Browning hmgs look so similar one might think they must be similar internally too, but there the Italian gun was different from US one in every aspect. US M2 hmg bolt is locked by a lock sliding vertically in rear of barrel extension, while Breda SAFAT has it's lock in form of a 'hook' pivoted in rear of barrel. M2 pulls cartridges from belt and loweres them to feeding line in T-slot in face of bolt by pivoted extractor. In Breda SAFAT's bolt there are symetric extractors to pull cartridge from belt and it gets lowered to feeding line by a oblique ramp in receiver. Also belt and firing mechanisms of both guns are different. To sum up: Breda SAFAT is indigenous and as original as it gets and has nothing to do with Browning guns in it's operation, apart of course from the very basic principle of action of short barrel recoil.

afaik breda it's derivated from browning .30 not the .50

[Micdrow]

Interesting stuff guys, many thanks!!!

Both Browning guns were very similar and Breda SAFAT was completely different from both.

[CharlesBronson]

Thanks for the correction, I shall look at my sources again.
