Dear All

In recent discussion re. the Italian bomber projects, Hesham mentioned two requirements for fighter aircraft -

1) single seat fighter:Macchi MC-300,Fiat G-58, Piaggio P-125,Reggiane Re-2005.

2) twin engined fighter reconnaissance:Fiat CR-25,Romeo Ro-53 ,Caproni Ca-150;Ca-160;Ca-401 and Breda Ba-94

Now thanks to other members we know about the G.58 and the Re-2005, but does anyone have information and drawings/plans of these other un-built projects?


Actually, the first competition...never was. There were successive spot requests from Regia Aeronautica to individual companies and some unsolicited proposal from individual companies regarding twin boom fighters, both original and derivative. Time span is from mid-1941 to first half of 1943. As for the MC-300, it never existed. The proposed (on exploratory request fro RA) coupled-fuselage derivative of MC-205 didn't even receive a numeral. An MC-301 did exist, but was earlier, and part of the Caccia Combattimento competition of 1938-39. The Piaggio P-125 is another entry in the Caccia Combattimento and the Bombardiere Normale competitions (two designs very similar); it was designed by Capt. Santangelo of the Genio Aeronautico (DSSE). The bomber version was outsourced to Piaggio for prototype production but the company did her best to NOT do it (succeeding...). So, the P.125 wasn't even a fighter strictu sensu. In the end, the only twin boom fighters built issuing from the above mentioned spot requests were SM-91 and SM-92, the latter NOT a derivative of the former. I'll illustrate the complex histories of those (and more) in my forthcoming book for Giorgio Apostolo Editore. Consider this as an official announcemnet. Publication date: March 2009.
Surely Reggiane 2005 and Fiat Cr.25 was built ! ;D
My dear Skybolt,

for the Macchi MC-300 and the competition,please see;
The built Re.2005 was the regular one. The Re.2005 hinted is the twin-fuselage Re-2005 (for want of a name)....
Cr-25, sure, but I didn't talked about that competition.
And, sorry Hesham but that competition is pure fantasy. For one, the original SM-91 was CANCELLED in July 1941, and resurrected in late 1942 as a zerstorer version of the SM-88. The Corsaro is much later, late 1942-early 1943 and competed not with the cited projects but with another Caproni, and perhaps with a MArchetti project (SM-94, not the SM-94 of 1937, wich was a civilian airliner).
See here for the SM-91 story,2737.msg22100.html#msg22100
And here for the Corsaro's (plus the Ca-184) one:,2411.msg20201.html#msg20201
This forum has really a lot of info already published. Please use the search facility, is one of the proud point of the Mighty Overscan ;)
BTW, I know very well the source of the Polish guy.. and I prefer not cite it here for love of my fatherland... it is a person who disseminated a lot of personal speculations like documented truth.
Uh, forgot: it is probable that the night-fighter line of the late 1943 Regia Aeronautica would have comprised the Sm-91 and the often unmentioned BZ-303, another evolution of the Can Z-1018. The BZ-303 would have been called Leone III. Finally, the twin-fuselage early 1942 competition is a mere speculation, born from the fact that the SM-92, the G-58 and the Re-2005bifusoliera seem to share the same requirement. No one (me included) has ever discovered an actual piece of paper describing, or even hinting at an official requirement.
Skybolt said:
(...) and the often unmentioned BZ-303, another evolution of the Can Z-1018. The BZ-303 would have been called Leone III.

I've read somewhere, but I don't rember where or when, that the Cant Z-1018 Nightfighter (the nomclature BZ-303 is something new to me) was to be equipped with an Italian radar (Grifo??), please Skybolt can you confirm this particular, or it was only a flight of fantasy??

It is true that RA was equipped with a small number of Dornier and Messerchmitt nightfighters but any of them had radar?

Thanks in advance.
AFAIK no "caccia scientifica" plane under the Regia ever used an airborne radiolocalizer n combat. I know that someone wrote a lot on this, with numerous flights of fancy. I'll check this night, though. I can confirm that the BZ-303 was to have a radiolocalizer onboard. The idea was probably to use two types of aircraft, one with radar and one w/o, vectored by terrestrial radars (the SM-91).
The CANT Z-1018 was to be a medium fast bomber produced by CANT, Breda and someone else (Anello Leone). When Zappata transferred to Breda, all evolution of the 1018 per se stopped. The BZ-301 was an high-altitude derivative, and the BZ-303 a night fighter.
This is fascinating information Sky...
Any articles (or a book) about in the planning phase ;D
Yes Paul, I'll insert some "scenario" info in the SM-91,92,93 book planned for March 2009 release.
Confirmed, no combat missions with radar onboard for Italian night fighters. In late spring 1943 Italy obtained a dozen of FuG 202 Lichtenstein BC. Two were destined to 1018s. The installation of the antennas was completed on July 8 1943. In parallel, there were developments at DSSE in Guidonia on national radars. First was the Argo, an experimental long distance localizer. From this derived the "Arghetto" (AKA "Vespa"), that was to be a naval search airborne radar (tested on an SM-79 and a 1018). The final development was "Lepre", a reduced-size "Vespa", targeted to night fighters. Had the war continued post-september 1943, this would have been standard equipment for night fighters.

here is the Caproni Ca.153 and Ca.365 fighter projects.

does anyone hear about Breda Ba.206 and Ambrosini SAI-402 fighter projects ?,
the Breda Ba.206 was developed from Ba.204 and the SAI-402 was lightweight
fighter as I know.

the Breda Ba.206 was a fighter/trainer and capable to be ground
attack aircraft project,developed with Ba.204 to the late of 1930s

does anyone hear about Breda Ba.207 Project ?.
From Aerofan 1/1980,

here is the Breda Ba.204,which was a multi mission aircraft,fighter,fighter-trainer and
turret fighter

My Dear Hesham,
i'm not familiar to the way of linking this post to another in the same board, but if you search C.208 you can find a sequel of post about it.
The C.208 is sometime referred as the Agusta AC.208 as was designed from Mario Castoldi, already retired from Aeronautica Macchi, for Agusta. The project was a primary trainer for one of the first postwar requirements of Aeronautica Militare, roughly in the same class of the Swiss Pilatus P.2. Later on, for an iteration of the same theme, the aircraft was redesigned by Eng. Filippo Zappata as the Agusta AZ.4.
As far as I know nor the C.208 neither the AZ.4 were built
Thank you my dear Nico,

and I know Agusta-Castoldi AC.208,but here the C.208 was a project for a fighter,intended during the WW2,
also the C.209 was a jet aircraft or not (in the article) ?.
Hi Hesham,
now I understand. In fact, in late seventies there were rumours about a post-war C.208 and C.209 designer by Castoldi as adviser for Macchi. If I'm right was late journalist Italo de'Marchi that published those information that I reported on later occasions.
In fact no proof of those project surfaced: the C.208 was described as a C.202/205 with Merlin engine, for competition with FIAT G.59. In reality an engine mount for a Packard Merlin on the fuselage of a 202/205 was developed by Macchi but when the engineering department was already directed by Ermanno Bazzocchi.
About a C.209 intended as a Macchi proposal for a first generation jet fighter, probably is a mere invention. Castoldi lacks any experience on jet propulsion and, moreover, the design office was already directed by Bazzocchi.
Thank you my dear Nico for your explanations,

and for C.209,all thing about it here;,7992.msg70317.html#msg70317

A G.55 with a more powerful DB 603 engine. Proved to be far superior to the Bf 109K and Fw 190D, but was not allowed for service by the Germans. Their own stupidity that helped us win...

I don't want to make a new topic to solve my long time problem with the designation of FIAT CR.25, it concerns Italian fighter projects in the end.
Question is why the FIAT CR.25 designed in 1937 has lower number than FIAT CR.30 which designing begun in 1930 ;
both machines were designed by Celestino Rosatelli, though.
Is it possible that originally designation of the aircraft should be FIAT BR.25 as it was intention to create a high-speed light bomber
and reconnaissance machine at the start, with the bomb-aimer place in the nose and full bombardment outfit ?
Dear friends,
here I share a pic about a wooden model of Caproni Ca.401 with single rudder.
Hope you'll enjoy!
