I have attempted to clean up the three-view arrangements of the NC 270, 271, 280, 281, 290 and 300 until we can find better quality scans:

Very interesting find indeed, but I need someone to explain the combination of the inlet and
the shown forward view. Would the air be guided by a glass plate into the bifurcated inlet tubes ?

Hesham,
I only find a 3V of the SNCAC NC-1080 naval fighter prototype. But unfortunatly nothing on the NC-1090.
So just in case.

From "Les avions de combat francais 1944-1960" Jean Cuny Volume 1 "Chasse-Assault", Collection Docavia Editions Lariviere 1988

Each of the three desings that took part in the naval fighter competition (NC.1080, VG-90, Nord 2200) was to be armed with three 30-mm cannon. Do you have any idea what type of cannon was envisaged as their armament?
How were the guns to be installed in the fighters? My thinking is that there should be an assymetrical arrangement...

My dear Petrus,


all of them are from Hispano-Suiza kind.

For the VG 90, the type is said to have been the HS 602 (Jean Cuny "Les Avion De Combat Francais",
Tome I, Docavia).
For the NC 1080, the installation would have been under the cockpit floor, so, due to wheel well
of the nose wheel, certainly an assymetrical arrangement would have been needed.
The VG 90 had the ammo boxes in the central wing, so the guns would have been there, too,
assymetrical again.
Couldn't find an exact location for the Nord 2200.
Neither of those prototypes was ever fitted with guns, AFAIK, but for all a change to four
20 mm guns was contemplated.
It takes a long time, before all mistakes are made ...

Jemiba, thank you very much for your reply.

As for the NC-1080, I've taken a look at the document "Le projet PA 28 et les avions à ré-action français embarqués", which used to be available at http://www.hydroretro.net/ but it is not anymore (thankfully I downloaded it some time ago; if anybody would like to have it please send me a PM).
The document says: "La cabine pour deux hommes d’équipage doit être chauffée, étanche et dotée de respirateurs, blindée"... DEUX HOMMES means TWO MEN, so it suggests that the NC-1080 was (or was to be) a two-seater. On the other hand what may be seen in the pictures of the NC-1080 is a cockpit for apparently one man. Other contenders in the naval fighter competition (VG-90 and Nord 2200) looked similarily.
Elsewhere the document says that the naval fighter requirement to which the NC-1080, VG-90 and Nord 2200 were built foresaw a radar, which may correspond with the two-man crew arrangement.

All these pieces of information cause further doubts rather than certainty about the designs. Do you have any ideas how to clarify the doubts?

Installation of a radar not necessarily meant a crew of two. Think of the Sabre or MiG 17/19, they
were fitted radar as single seaters, too. Nevertheless, adding the role of a dedicated night fighter,
which back then was regarded as needing a second pair of eyes, may have been envisaged. But
SNCAC was offering the NC.1072 for that role, considerably bigger and certainly with a range and
loiter time those single engined designs couldn't match.

There migh have been projects for other variants, but the sole NC-1080 ever built, F-WFKZ, was definitely a single seater.  Look at this cockpit:

Tome I, Docavia).

In "Les chasseurs Dassault. Ouragan, Mysteres et Super-Mysteres" by Jean Cuny there is a photo of Hispano-Suiza HS-603 as well as a table presenting data on several aircraft guns of that period of time.
