Some background:

In the grand scope of World War 2 fighter aircraft there is a little-remembered French design designated the Arsenal "VG-33". The aircraft was born from a rather lengthy line of prototype developments put forth by the company in the years leading up to World War 2 and the VG-33 and its derivatives represented the culmination of this work before the German invasion rendered all further work moot.

 

The Arsenal de l'Aeronautique company was formed by the French government in 1936 ahead of World War 2. It began operations with dedicated design and development of a fast fighter type until the German conquer of France in 1940 after which the company then focused on engine production after 1945. Then followed a period of design and construction of gliders and missiles before being privatized in 1952 (as SFECMAS). The company then fell under the SNCAN brand label and became "Nord Aviation" in 1955.

 

The VG-33 was the result of the company's research. Work on a new fast fighter began by Arsenal engineers in 1936 and the line began with the original VG-30 prototype achieving first flight on October 1st, 1938. Named for engineer Vernisse (V) and designer Jean Gaultier (G), the VG-30 showcased a sound design with good performance and speed during the tests, certainly suitable for progression as a military fighter and with future potential.

 

Development continued into what became the VG-31 which incorporated smaller wings. The VG-32 then followed which returned to the full-sized wings and installed the American Allison V-1710-C15 inline supercharged engine of 1,054 horsepower. The VG-32 then formed the basis of the VG-33 which reverted to a Hispano-Suiza 12Y-31 engine and first flight was in early 1939, months ahead of the German invasion of Poland. Flight testing then spanned into August and serial production of this model was ordered.

 

The VG-33 was one of the more impressive prewar fighter ventures by the French that included the Dewoitine D.520, understood to be on par with the lead German fighter aircraft of the period - the famous Messerschmitt Bf 109.

 

Only about forty or so French Arsenal VG-33 fighters were completed before the Fall of France in 1940, with 160 more on order and in different states of completion. Despite the production contract, Arsenal' engineers continued work on the basic design for improved and specialized sub-types. The VG-34 appeared in early 1940 outfitted with the Hispano-Suiza 12Y-45 engine of 935 horsepower, which improved performance at altitude. An uprated engine was installed in VG-35 and VG-36, too. They utilized a Hispano-Suiza 12Y-51 engine of 1,000 horsepower with a revised undercarriage and radiator system.

 

VG-37 was a long-range version that was not furthered beyond the drawing board, but the VG-38 with a Hispano-Suiza 12Y-77 engine that featured two exhaust turbochargers for improved performance at high altitude, achived pre-production status with a series of about 10 aircraft. These were transferred to GC 1/3 for field trials in early 1940 and actively used in the defence against the German invasion.

 

The VG-39 ended the line as the last viable prototype model with its drive emerging from a Hispano-Suiza 12Z engine of 1,280 horsepower. A new three-machine-gun wing was installed for a formidable six-gun armament array. This model was also ordered into production as the VG-39bis and was to carry a 1,600 horsepower Hispano-Suiza 12Z-17 engine into service. However, the German invasion eliminated any further progress, and eventually any work on the Arsenal VG fighter family was abandoned, even though more designs were planned, e .g. the VG-40, which mounted a Rolls-Royce Merlin III, and the VG-50, featuring the newer Allison V-1710-39. Neither was built.

 

Anyway, the finalized VG-38 was an all-modern looking fighter design with elegant lines and a streamlined appearance. Its power came from an inline engine fitted to the front of the fuselage and headed by a large propeller spinner at the center of a three-bladed unit. The cockpit was held over midships with the fuselage tapering to become the tail unit.

 

The tail featured a rounded vertical tail fin and low-set horizontal planes in a traditional arrangement - all surfaces enlarged for improved high altitude performance.

The monoplane wing assemblies were at the center of the design in the usual way. The pilot's field of view was hampered by the long nose ahead, the wings below and the raised fuselage spine aft, even though the pilot sat under a largely unobstructed canopy utilizing light framing. The canopy opened to starboard.

 

A large air scoop for the radiator and air intercooler was mounted under the fuselage. As an unusual feature its outlet was located in a dorsal position, behind the cockpit. The undercarriage was of the typical tail-dragger arrangement of the period, retracting inwards. The tail wheel was retractable, too.

 

Construction was largely of wood which led to a very lightweight design that aided performance and the manufacture process. Unlike other fighters of the 1930s, the VG-38 was well-armed with a 20mm Hispano-Suiza cannon, firing through the propeller hub, complemented by 4 x 7.5mm MAC 1934 series machine guns in the wings, just like the VG-33.

 

The aircraft never saw combat action in the Battle of France. Its arrival was simply too late to have any effect on the outcome of the German plans. Therefore, with limited production and very limited combat service during the defence of Paris in May 1940, it largely fell into the pages of history with all completed models lost.

The kit and its assembly:

I found the VG-33 fascinating - an obscure and sleek fighter with lots of potential that suffered mainly from bad timing. There are actually VG-33 kits from Azur and Pegasus, but how much more fun is it to create your own interpretation of the historic events, esp. as a submission to a Battle of Britain Group Build at whatifmodelers.com?

 

I had this project on the whif agenda for a long time, and kept my eyes open for potential models. One day I encountered Amodel's Su-1 and Su-3 kits and was stunned by this aircraft's overall similarity to the VG-33. When I found the real VG-38 description I decided to convert the Su-3 into this elusive French fighter!

 

The Su-3 was built mainly OOB, it is a nice kit with much detail, even though it needs some work as a short run offering. I kept the odd radiator installation of the Suchoj aircraft, but changed the landing gear from a P-40 style design (retracting backwards and rotating 90°) into a conservative, inward retracting system. I even found forked gear struts in the spares box, from a Fiat G.50. The covers come from a Hawker Hurricane, and the wells were cut out from this pattern, while the rest of the old wells was filled with putty.

 

Further mods include the cleaned cowling (the Su-3's fuselage-mounted machine guns had to go), while machine guns in the wings were added. The flaps were lowered, too, and the small cockpit canopy cut in two pieces in, for an opened position - a shame you can hardly see anything from the neat interior. Two large antenna masts complete the French style.

 

 

Painting and markings:

Again, a rather conservative choice: typical French Air Force colors, in Khaki/Dark Brown/Blue Gray with light blue-gray undersides.

 

One very inspiring fact about the French tricolor-paint scheme is that no aircraft looked like the other – except for a few types, every aircraft had an individual scheme with more or less complexity or even artistic approach. Even the colors were only vaguely unified: Field mixes were common, as well as mods with other colors that were mixed into the basic three tones!

 

I settled for a scheme I found on a 1940 Curtiss 75, with clearly defined edges between the paint fields. Anything goes! I used French Khaki, Dark Blue Grey and Light Blue Grey (for the undersides) from Modelmaster's Authentic Enamels range, and Humbrol 170 (Brown Bess) for the Chestnut Brown. Interior surfaces were painted in dark grey (Humbrol 32) while the landing gear well parts of the wings were painted in Aluminum Dope (Humbrol 56).

The decals mainly come from a Hobby Boss Dewoitine D.520, but also from a PrintScale aftermarket sheet and the scrap box.

 

The kit was slightly weathered with a black ink wash and some dry-painting, more for a dramatic effect than simulating wear and tear, since any aircraft from the VG-33 family would only have had a very short service career.

 

 

Well, a travesty whif - and who would expect an obscure Soviet experimental fighter to perform as a lookalike for an even more obscure French experimental fighter? IMHO, it works pretty fine - conservative sould might fair over the spinal radiator outlet and open the dorsal installation, overall both aircraft are very similar in shape, size and layout. :D
