Just out of curiosity, does anyone know anything about the P-48, swiss 4 engined jet fighter with 4 Sulzer D-45 engines
IT's from a book called: Der Schweizer P-16 by Hanspeter Strehler
If anyone happens to have something about it, i am burning to know more about it.

The Image says September 1947.

In addition the image mentions a couple of things:
Engines: 4x Sulzer D45
The fact that it has 6 guns, likely 6x 20mm guns considering the timeframe and the fact that it's likely connected to the P-25
And if we take a look at the Stollen image, it could also be easy to calculate the exact dimensions.
However i'm missing crucial information such as weight, top speed, stall speed etc.

Thank you Mizutayio,

but by that time there was no P-16,and the series itself was not suitable to this period,
maybe it came from F + W company ?.

It clearly was from FFA, as they were the only ones using the P-xx Designation, EFW aka. F+W used N-xx designations.

from P ?.

It's quite easy if you know their naming practice and why they went with the P-25 series first.

Well you might know that just after the war, Jet engines were rather weak, so it was best to use 2 jet engines instead of one.
Hence why P-25 came first.

And here we go to the naming:
the first digit means the amount of engines, the second digit indicates the plane design and the number after the dot (.) shows the variant.
So P-48 in this case is the eigth design of a four engined jet fighter.
P-16 is the sixth design of the single engined fighters. ( hence P-12, P-13, P-14, P-15, P-16 and P-17)
and P-25.11 is variant 11 of the fifth design of the 2 engined jets. (P-25, P-26)

And the P-2x and P-4x planes just happened to come before the P-1x when better engines became available.

Afaik, this naming rule does not apply to the EFW planes (as N-20 had 4 engines)

You may find it interesting that the book "Schweizerische Strahlflugzeuge und Strahltriebwerke" by Georges Bridel was from 1974 to 1977 published in ten parts in the "Schweizerische Bauzeitung" magazine. The magazine's content has been digitalised and is available for free at www.e-periodica.ch.

Here you've got links to all the parts of the book:

Probably a difficult request, but...would anyone here have access to a full-page back cover advertisement (yes, I know this may not be correct topic) that had appeared in Flying Review International circa 1963-64 featuring a dark-colored scale model of FFA P-16 in center? Perhaps it was from Hispano-Suiza? Don't believe the aircraft itself was even identified theron. (A memory from childhood.)

Yes, exactly, but that must be from a Swiss (or German) magazine. Thanks so much for almost immediate reply/gratification.

Real damn shame the P16 was not put into production. Was a really big missed opportunity for Switzerland, which honestly could've and should've been analogous to Sweden's; a small, yet skilled fully vertically integrated industry. Props to Pilatus for delivering some truly great aircraft, but the P16 would've given Switzerland the real experience to produce indigenous high end combat aircraft. While not practical these days for small independent countries, they would've been better poised to be a partner in developing new fighters with foreign companies.

Frequently, FFA-16 has been mentioned, as starting point in development of Learjet twin-engined business jet.
For eample Wikipedia article.

I wonder, how American industrialist Lear obtained rights (or possibility) to use FFA-16 parts for commercial aircraft? Or why Switzerland' government didn't involved in his company? Now we knew Pilatus as sole and successfull Swiss-based aircraft manufacturer. Perhaps, two compnies have been too much for small country?

The FFA company was a private company, not a government one. So the swiss government had nothing to do with the Lear-Deal.

Hello, Mustang59!

Thanks for details.
Perhaps, I wasn't clear in my answer.
I'd try to understand, could Swiss government participate in some way in transition of FFA technology to USA, in order to, say, compensate their expenses for failed P-16 program, or support another aircraft producer in Switzerland.
