Hi all, we all know the Savoia-Marchetti S.M.-series, but I have gaps...
If you can please tell me more about S.M.97 / 98 / 99 / 100.

Regards Maveric

I think it's up to me:

Sm-97 No data. COULD (emphasis) be the intended designation of an un-named four-engine, triple-fin, trycicle landing gear civilian transport dated from October 1943. An evolution of the SM-95 with a new fuselage.

Sm-98. No data/not assigned

Sm-99. This designation is found in the mid-war private notes of Ing. Ermanno Bazzocchi (of later Aermacchi fame) as a potential competitor of the design he was studying at that time of a two-three engines light-to-mid transport. Could have been a "fictional" designation for some sort of late transport/civilian version of the S-79 with new engines (like the ones sold post-war to Lebanese Air Force).

Sm-100. Not assigned. I personally sometime use it to designate a misterious design documented only by an unidentified model in the Agusta Museum in Cascina Costa. Evidently inspired by Miles "X" designs (particularly Miles X.2 from 1937-1938), figure it as an airplane with a fuselage with an airfoil section mated with the Sm-95 wings and engine nacelles. Actually it could be a "milesque" version of the supposed Sm-97.

Don't you think the SM.99 was twin-boom like the SM.88 or twin-hull like the S.55, S.66, SM.77? Something like a SM.79 twin (bifusoliera)?

The only thing it is "known" on the SM-99 is that Ing. Bazzocchi used that designation to indicate a potential competitor of his project. The use of similar end number or repetition of numbers (like the 55, 66 and 77 series) was used by Marchetti, but, for example, the first design of the SM.88 (designation already officially assigned at ministerial level) had a single tail... since it was an evolution of the SM-86W. More on this in the forthcoming Italian Secret Projects, naturlich. Marchetti designed a twin boom transport, but it had a designation totally unrelated with previous "repeated digit" type.

The SM.97 was a triple fin, 4 engine, tricycle gear airliner study, while the SM.99 was a 2-3 engine transport (https://www.secretprojects.co.uk/threads/forthcoming-italian-secret-projects.7394/page-3#post-137003).
