After the South American War, the FAB (Força Aérea Brasileira) was in very poor shape, having gone from a high of 709 combat aircraft prior to the war in 1934, to around 50 serviceable aircraft, most of which were obsolete biplanes. Several promising aircraft designs had been halted by the war, and once production resumed in 1937 were nearly obsolete. The EMBRAER EMB-38 is perhaps a prime example of this, which while it was a decent design in 1934, the rapid pace of development in the late 1930's meant it was near obsolete when it first began entering service in 1937.

The story of the Sienar V-31 is an interesting one, as it is a naval fighter for a country that does not yet have an aircraft carrier afloat. Design of the aircraft began before the SA War began, and although the design work was completed before the end of the war, the Sienar V-31 didn't see combat due to production being delayed due to the war. Production commenced in early 1937, even though there still wasn't a Brazilian carrier for them to fly off of, they equipped 4 land based squadrons in FAe IV for a total of 64 aircraft produced. Production ended in 1940.

Another aircraft designed prior to the SA War, its story is similar to that of the Sienar V-31, being designed for a carrier, but having no carrier to operate off of. Production began in 1937, with 2 squadrons in FAe IV for a total of 32 aircraft produced.

More to come.

It's good to see these getting airtime (pun intended).

Nice write-up with some good pictures too.

Brazil seems to have been affected but I'm sure they'll catch up with some better designs. Making do with what you've got is worth extra points when its home built and you can point and say "we designed and built that for our air force."

True, the EMB-39 (P-43) should hopefully close the gap somewhat, and the EMB-40 (P-47) will likely close the gap completely. The Brazilians will be making some export orders for aircraft, starting in 1939 mainly bombers, and transport aircraft although the Brazilians do like the I-02.

Does anyone have a reasonable estimate on how many aircraft Brazil can produce in a year in WW?

Now that is a very important question.
It looks like in WW a piss poor country like Poland managed to build 300 tanks throwout 1936-1937 period with RL production was under 150 in years 1936-1939.

It looks like any one can make there factories work at capacity and no one voices there objections.

The airframes are not that hard too build.
What is usually a problem are engines, avionic , pressurized cockpits and folding landing gears.

Even relatively small countries OTL were able to build a few hundred aircraft a year, like Marek said armament, engines and landing gear were often the bottlenecks

Have you considered the Seversky 2PA as an light attack companion to your P-35? Or replacement for the V-19

This is a RL order from Poland in 1939
Keep in mind the failing delivery dates and producing half what was ordered were common.

PZL
124 PZL 37 Los bombers. To be delivered by 1.IV.1939,
from that number half was ready with 40 nearing completion and 20 to be assembled while company was moving from Okecie to Mielec.
-160 light recon bombers PZL 46 Sum first prototype was undergoing testing second prototype nearing completion.
-500 pursuit planes P.50 Jastrzab, first prototype waiting for landing gear second for an engine first 50 was in production.
Deliverers awaited in Autumn 1939
LWS
200 LWS 3 Mewa recon planes. In production. delivery expected August 1939
65 RWD 14 Czapla series nearing end.
PWS
130 twin engine trainer PWS 33 Wyzel, 2 prototypes ready serial production is being set up.
150 acrobatic-trainers PWS 35 Ogar bi-planes.
two prototypes ready and tested production preperatin in infant stages.

Keep in mind that this is a country on war footing throwing money at the problem and on a short trip to bankruptcy.

FMA welcomes Brazil's interest in the I-02 and can arrange some test flights in pre-production machines later on this year. FMA could deliver the first Brazilian fighters late 1939 (I'm assuming Spartan will build Atlantis' fighters and ENEAR Chile's so FMA will be building the rest).

Brazil is also welcome to trial the carrier-fighter version but that won't fy until 1940 and under the agreements Spartan will be building all the I-02N fighters. (Spartan knows more about this than FMA, that's why the I-01N is so overweight!)
