Savoia-Marchetti S.55

An epoch-making design in every sense, the S.55 prototype flew in 1925. In an era still committed to the biplane flying-boat, it had a revolutionary formula: a cantilever shoulder-wing monoplane with twin hulls and delicate booms supporting a twin-fin triple-rudder tail assembly. Side-by-side pilots' cockpits were located in the leading edge of the wing centre-section. Twin tandem engines were carried on struts over the wing. Originally these were 298kW Lorraines, but power was gradually increased to 559kW Assos on the 1933 S.55X.

Total production exceeded 200. The type formed the main equipment of Italy's maritime-bombing squadriglie for many years, 13 remaining on charge (but in reserve) in 1939. The S.55C and S.55P civil passenger versions operated Mediterranean routes for a decade.

The S.55 achieved great fame through spectacular long-distance flights: Lieut-Col the Marchese de Pinedo flew the Santa Maria from Sardinia to Buenos Aires and then through South America and the USA in 1927; later Brazilian, American and Russian crews achieved world headlines. The S.55 will be chiefly remembered, however, for the remarkable mass formation flights led by the famous Italo Balbo. The first began in December 1930 when specially modified S.55As covered 10,400km between Italy and Brazil. The second flight (three years later) was even more impressive: 24 S.55X machines overflew the Alps and continued in stages via Iceland, Greenland and Labrador to Chicago for the 1933 Century of Progress Exposition. The international press coined the phrase 'Aerial Armada' to describe the flights.

I have a large quantity of information on the S55 including facsimiles of the Chicago "Raid" program, engineer drawings, numerous photographs, and even a letter from one of the original Savoia-Marchetti engineers describing a flight over Lake Maggiore. I have written articles about this aircraft and been interviewed (via telephone) by the BBC. I am still very interested in this plane and am more than willing to share information with anyone who shares this interest. What I would really like to see is the construction of a replica aircraft which could then repeat some of the SM55's famous flights.

Ho ereditato da mio padre un modellino in rame dell'aereo Savoia-Mrchetti SM55 ed lo volevo restaurare ma di questo aereo non ho trovato traccia di nessun progetto. Mio padre ha svolto il servizio militare nel 1931 quindi penso che il sopra citato modello fosse motorizzato Fiat, a conferma di tutto cio' ho notato la mancanza dei rinforzi sulla parte finale dei tubi (nel mio caso ovali anziche rotondi) di sostegno dei timoni di direione e di profondita' e avrei anche delle foto da mandarvi. Vi ringrazio di tutto quello che potrete fare per me.

Quero construir um aeromodelo reproduzindo o Jahú, mas não encontro planta ou desenho. Alguém pode me ajudar?

I have a DVD made from an old 8mm film taken by my father in 1933 when Italo Balbo landed in Chicago. It shows the planes flying overhead and landing in the area north of Navy Pier. Other scenes show the crews attending mass at Holy Name Cathedral and the parade down Michigan Avenue.

Sgt.KAR98, 10.07.2009

This plane was used for military purpouses too?
I read they used one in the 1932 revolution.

walter civitico, cac_sabre=yahoo.com.au, 27.05.2009

I have a number of original photos of S-55s which I believe were taken during the Chicago trip. Sourced via a relation who was a photographer in the RA

Here's a link to a fascinating article about Francesco de Pinedo's S-55 which burned and sank in the United States in 1927:

I flew in the S-55 twice in one day when it visited Chicago. I was a high school student at the time. It was noisy in the hulls, partaiculaarly during take-off, which accented a thrilling experience.
The seaplane made a number of flights that day from the Navy Pier area with newspaper reporters, primarily, as passengers.

Steagall-Condé, thesign=sercomtel.com.br, 01.11.2008

Superb informations! I am doing technical-renderized drawings of the S-55 to a hobby magazine here in Brazil (hobbynewsDOTcomDOTbr) but I missing some points, like a detailled Isotta-Fraschine double engines views and, mainly, a logotype from the SAVOIA-MARCHETTI factory, please, if somebody know something about it, contact me.

I saw the armada July 1933 on the return trip New York to Shediac Bay as it crossed our farm about 10 miles from landing at Shediac. Does anyone have a good quality photo of the SM.55X that they can email to me.

Thanks

I have a vintage photograph of this aircraft from about 1928 in Los Angeles. My great uncle was news photographer at the time and the plane must have visited LA. The side of the plane read American Aeronautical Corporation and on the one of the pontoon is an insignia "S55P" two women are on the wing waving to the camera. It is an interesting view of the front part of the plane showing the pontoons, wing and engine.

It is the construction number.

Lydia Palisi, wlmburgA aol.com, 05.12.2006

I have a painting of one of these planes ... the number on the side of the plane is 10015 .... can you tell me what this number might indicate?
This small painting has been in my family for many years and I'm afriad that no one is left to answer questions about the plane or why there was a painting of it in our family... the painting is signed with the initials E D... with D being the larger of the 2 letters.... any info you can provide would be greatly appreciated... thank you.
