In September 1937 Fokker produced the new designs  Ontw.150
and Ontw.151.These had a radial-Bristol Hercules- and an
in line -DB 600H or RR Merlin - engine respectively.
These parallel and completely new designs attracted the
the interest of the ML and were soon referred to as D.22.

In  June 19 1939 a data sheet appeared mentioning a D.21
with a Bristol Perseus engine and six guns.
On June 22 , a D.24 data-sheet appeared with exactly the same information .
Notes on a drawing of Ontw.150 ( see drawing presented by Hesham)  indicates
that it could have been a modification of that type.

The D.24 should have been Fokker Ont.192.

So, any reason why Fokker was so left behind? The D.XXI was their best fielded fighter and it had fixed undercarriage. Was it because of lack of aluminium expertise, so they built wood- and fabric planes which didn't work well at high speeds? No advanced glues or Mosquito style mold built sandwich structures yet available at that point?

Hi,

the P.126 was a project of 1935 for low-wing three-seat
light bomber.

Thanks to Lark, speaking Dutch, I have been directed to the book "Fokker G-1" (Lanasta publication*). From profiles in it, I drew slanting views of the projects Ontwerp 179 (Design 179) of 1939. Much more is included, but out of my special scope on 1939-45 years (for updating my "forked ghosts" site http://cmeunier.chez-alice.fr/update_FG.htm ).

Hi,


T.6W  was a developed version of T.V,fitted with two Bristol Hercules engines.
T.7W  was a twin-engined torpedo recce floatplane,never built.
B.5     was a long range three-engined recce,torpedo and bombing flying boat.
D.24   was a single seat fighter,I spoke about it before.

Good find Hesham, can you tell us the source for further reading ?
To my opinion, the B.5 bears more than a superficial resemblance to the
Do 24, apart from the wing floats substituting the stub wings. Maybe for
patent reasons ?

Thanks for that link, interesting reading !
As it seems, the very similar layout really was just the result of the requirement.
And Fokker even had prepared a design with stub wings, so avoiding license fees
couldn't have been high on the priorities !

 In 1935 Fokker designed the B-V reconnaissance flying boat for the MLD (Dutch Naval flying service) as a replacement for the Dornier Wal. No aircraft were ordered and no aircraft was built.
