The Savoia-Marchetti S.M. 79 was a three-engine medium aircraft developed by Savoia-Marchetti, also known as the Società Idrovolanti Alta Italia (SIAI) later SIAI-Savoia. Initially developed as a fast passenger transport aircraft, it was later adapted for use as a racing aircraft, and later as a medium bomber. From 1936 until 1939 it broke several records, both in the civil and military spheres with the Regia Aeronautica (Italian Royal Air Force), also becoming the fastest medium bomber in the world at the time. It was one of the most produced aircraft by Italy during the Fascist dictatorship and was used by 12 different air forces, both civil and military and remained in service until 1951 as a bomber for the Aeronautica Militare (Italian Air Force), and until 1959 as a bomber for the Lebanese Air Force.

History of the Project

During the 1930s, the Italian Air Force was among the world’s leading air forces, with cutting-edge manufacturing and designers.

Italo Balbo, a fervent fascist and Air Marshal, managed to break several records aboard several seaplanes of the Società Idrovolanti Alta Italia (Northern Italy Seaplane Company). In 1928 he made a bold request for the time, asking SIAI for an aircraft capable of taking off from Italy and reaching any location in Libya carrying 8 to 10 passengers. All in the shortest possible time.

It must be emphasized that the Italian fascist regime tended to support domestic efforts in any field or industry in order to bolster publicity and popular support, which is why Italo Balbo required a fast plane, to be able to outcompete French and British air transports on Africa-bound routes to Libya, Somalia, and Eritrea.

In early 1933, Australian nobleman Sir Mac Pherson Robinson created a challenge to reach Melbourne from London in a single intercontinental flight. In 1933 the SIAI decided to compete for the Mac Robinson Cup, and at the same time to satisfy Balbo. Seasoned engineer Alessandro Marchetti (1884-1966) was put at the helm of the project.SIAI put so much emphasis on the project, that Marchetti’s initial blueprints for the new S.79 were dated February 21, 1933.This cutting-edge project featured low wings, retractable landing gear, Handley Page flaps and three Isotta Fraschini Asso 750 engines of 900 hp each.

Subsequently Marchetti was forced to modify the blueprints, first with three FIAT A. 59 RC engines developed by the American Pratt & Whitney R-1690, finally ending up on Piaggio P. IX R.C. 40 engines of 610 hp developed from the French Gnome-Rhône 9K ‘Mistral’.

History of the Civilian Prototype

In May 1934, the last modifications to the project, and design of the first prototype were completed. The new plane was identified as S.79P or Passeggeri ( Passenger). It received the serial number 19001 and codename I-MAGO.

Through August and September of 1934, various parts of the aircraft were produced in SIAI factories in Sesto Calende in Lombardy, and were sent to the Novara Air Base in Piedmont . After being reassembled on October 8, 1934, and with SIAI test pilot Adriano Bacula and engineer Merizzi at the controls, the 19001 prototype made its first test flight.

The aircraft proved promising during the tests. There were excellent results as the aircraft had excellent handling, was easy to fly, and had a comfortable passenger cabin. On the other hand the engines, with only 610 hp at maximum power was not enough for SIAI and Alessandro Marchetti.

Piaggio sent one of its technicians during flight tests, engineer Risaliti, to try to increase the power of the engines, but he failed, managing to bring the aircraft to only 360 km/h at an altitude of 100 meters, and 390 km/h at 3,000 meters, while carrying 3 tons of ballast.

These results were impressive for the time, the Junkers Ju 52 for example had a top speed of 290 km/h, but not enough for a modern plane like the S. 79.

These problems forced the Italian technicians to change the engines with more powerful and reliable ones.

This decision was taken also because the Piaggio P. IX R.C. 40 engines led to two different incidents. The first occurred on 28 October when they attempted a record Novara-Rome route which had to be canceled due to engine failures and the plane returned to Novara.The second accident led to the fire of the engines which fortunately was shut down before the prototype was destroyed.

SIAI therefore decided to remove the Piaggio engines in February 1935, and replaced them with the 650 hp Alfa Romeo 125 RC.35, developed from the British Bristol Pegasus.

Due to the larger diameter, the engines received a new cowling, and finally, on April 5, 1935 Bacula and Merizzi took the re-engineered prototype into the air again.

The new tests yielded very favorable results and the plane claimed several records, the first was to be the first three-engine civil transport to break 400 km/h, and the second to travel from Novara to Rome (500 km) in just 70 minutes, which they accomplished on May 10, 1935.

In Rome, Adriano Bacula had the opportunity to familiarize some Italian pilots on the S. 79. Interestingly a delegation of French aviators led by Minister of the Air Denain with the aces Mermoz and Rossi was in the Italian capital. The French pilots admired the new three-engine plane for its modern design and maximum velocity.

Among the Italian aviators who tested the aircraft there were Maggior Biseo and his colleagues, elites of the 1st Experimental Center who expressed much praise for the Chief of Staff of the Regia Aeronautica, General Valle, on the new vehicle.

Returning to Novara to receive some modifications, such as increased range, on May 26, 1935 the S. 79 was back in Rome with all the required changes including 2 new tanks in the wings for a total of 820 liters of fuel.

The aircraft was registered by the Royal Air Force MM. 260 (Matricola Militare /Military Serial Number) and assigned on June 14 to the 1st Experimental Center.

On August 1, 1936 General Valle flew from Rome to Massawa, Eritrea in just 12 hours of actual flight with a stopover in Cairo for refueling, and returned to Italy 4 days later.

On October 3, 1935 the Kingdom of Italy start the invasion of the neutral Ethiopian Empire to colonize it. The Savoia-Marchetti S. 79 prototype was deployed as liaison plane by General Valle.

The second flight was made on January 6, 1936 when the plane carried General Valle, Biseo, Tondi as well as technicians and specialists Gadda, Ghidelli and Bernazzani.

During the representative trip to Ethiopia which ended on January 18 in Grottaglie, Puglia, the plane traveled 15,000 km proving to be very fast and efficient.

The prototype, MM. 260, was assigned to the Experimental Center but was employed by the 12° Stormo Bombardamento Terrestre (12th Ground Bombing Wing), and was modified to carry 6 100 kg bombs. It was tested on 20 May 1936 by Lieutenant Colonel Biseo and Captain Lippi on the Furbara shooting range.

The tests were repeated with captains Paradisi and Moscatelli of the 12° Stormo who demonstrated that the aircraft was an excellent platform for bombing.

Bomber Variant

In December 1935, SIAI-Savoia proposed a military version of the S. 79 powered by the powerful Gnome-Rhône 14K Mistral Major 14 cylinders with a output of 725 hp at 2,000 rpm, hence the name of the prototype S. 79K. However, the General Staff of the Regia Aeronautica rejected the idea of powering their bombers with foreign engines, and ordered 24 S. 79Ms (M for Militare / Military) to be equipped with Italian-made engines.

S.M. 79 Racing Aircraft or Medium Bomber?

From the first batch of the S.M. 79M, 5 aircraft were modified during production to be used in the civil field, and initially renamed Savoia-Marchetti S.M. 83C, and then returned to the designation Savoia-Marchetti S.M. 79C for Corsa (Racing).

The Savoia-Marchetti flown by pilots Tondi and Moscatelli

This variant flew without armament, the observer gondola and bomb bay also lost its characteristic hump to increase the aerodynamics of the fuselage.

The autopilot system was then enhanced, the on-board instrumentation adjusted, the door on the left side replaced by a smaller hatch above the wing, and its range was increased by adding tanks instead of the bomb bay for a total of 7,000 liters of fuel.

Other improvements concerned the compressors which, when upgraded, allowed the use of 100 octane petrol Also the transceiver system was replaced with a Telefunken model of greater power and reliability. The propellers were substituted with new variable pitch propellers produced by the French Ratier. New larger radiators were added to better cool the engines and finally, the landing gear was fitted with tires capable of withstanding the maximum weight of the plane fully loaded.

This version was created to participate in the tender organized by the French Aero Club for August 1937 which was to fly to the Istres (Southern France) – Damascus – Le Bourget (near Paris) route for a total of 2,900 km.

For the race it was planned to involve a Caproni Ca. 405 ‘Procellaria’ and two FIAT B.R. 20 but due to delays the Ca. 405 could not participate and the SIAI-Savoia produced a sixth S.M. 79C.

Flying the six aircraft were all pilots of the 205ª Squadriglia da bombardamento “Sorci Verdi” of the 12° Stormo Bombardamento Terrestre, the only Italian pilots who had received a pilot’s license for this aircraft.

Apart from the eight Italian aircraft, there were four French aircraft, a Bloch M.B.160, a Farman F.223, a Caudron C-640 and a Breguet 470 Fulgur, the only English one, the De Havilland D.H.88 Comet.

All took off from 1725 hrs on 20 August 1937, the first plane to land in Damascus was the I-FILU after 6 hours and 51 minutes at an incredible speed of 426.42 km/h.

Partial ranking in Damascus
Pilots Aircraft Name Racing Number Qualified Average Speed
Biseo and Mussolini I-BIMU I-5 Terzo
Cupini and Paradisi I-CUPA I-11 Secondo 415 km/h
Fiori and Lucchini I-FILU I-13 Primo 426.42 km/h
Lippi and Castellani I-LICA I-7 Ottavo 352 km/h
Rovis and Trimboli I-ROTR I-12 Quinto
Tondi and Moscatelli I-TOMO I-6 Quarto

The partial ranking podium was all Italian, in fact in Damascus five to six of the S. 79Cs arrived before the other aircrafts, the sixth and seventh were the FIAT B.R. 20s with an average speed of 299 km/h and 382 km/h.

I-LICA had problems with the constant pitch of the right propeller forcing the drivers Lippi and Castellani to travel the Istres-Damascus route for another six hours with only two engines.

The ninth plane to arrive in Damascus was the De Havilland D.H.88 Comet with an average of 356 km/h while the first French plane landed with an average speed of 305 km/h.

During the stop, the planes refueled and fixed the propeller. Due to bad weather it was decided to change course for the return and to fly in formation, thus loading an additional 500 liters of fuel.

One of the six S. 79Cs refueled at Damascus, though unfortunately it’s impossible to determine which one it is. In the background the French four-engined Bloch M.B.160 is visible. [modellismoitalia.altervista.org]
During take-off, one of the two FIAT B.R. 20 experienced rudder damage while the unfortunate I-LICA ended up hitting a pothole on the runway with the left wheel, breaking the landing gear and yawing violently to the left and making take-off impossible.

One hour after departure, the I-TOMO reported that it had a deficiency of 2,000 liters of fuel, while I-ROTR reported that it had to land in Ronchi due to excessive fuel consumption.

It was therefore decided to have the three remaining SM-79s arrive in Paris in formation. The plan was about to succeed, in fact I-BIMU sighted I-FILU and the I-CUPI but due to the lightning storms masking the transmissions, they could not make radio contact.

Biseo and Bruno Mussolini then decided to overtake the other two S.M. 79 to be recognized and make the formation, but when they reached the Alps they had to climb to 6,500 meters. However in doing so, they were forced to reduce the pitch of the propeller, and during the movement the central propeller went to the minimum pitch and jammed.

The two pilots then decided to land in Cameri where there were technicians who could repair their Ratier propellers. However, after a careful examination, during which the plane was refueled, the two pilots were informed that the propeller problem could not be repaired quickly. It was therefore decided to bring the central propeller to maximum pitch and the plane that had stopped for about 30 minutes took off again towards Paris.

The I-ROTR was unable to reach Ronchi due to lack of fuel and had to land in Pula where, after refueling, it was unable to restart because the electrical circuit of the starter magnet of the central engine had been damaged by hail.

Having repaired the fault, the plane continued the next morning to Bourget and was classified in 8th and last place.

The I-TOMO was unable to reach Ronchi and, again due to bad weather, had to land at the Lido of Venice where it ran aground, as the field was reduced to a quagmire by torrential rain, but thanks to the joint efforts of the airport staff and crew, the aircraft was able to leave after refueling.

The two FIATs also had to land due to problems.

Despite the bad weather and the unsatisfactory reliability of the propellers, at Le Bourget there were three S.M. 79s in the first three positions. The I-CUPI arrived at 1547 hrs on the 21st and circled up to 1602 hrs before running out of fuel, waiting in flight for the I-BUMU as the victory of Benito Mussolini’s son would have been a great benefit for the fascist propaganda. Then it was the turn of the I-FILU which landed at 1617 hrs, and finally at 1637 hrs Biseo and Mussolini arrived who, despite the stop, took a significant third place.

Four ground crew members ran to the I-11 S. 79C piloted by Cupini and Paradisi. [modellismoitalia.altervista.org]
Fourth was the De Havilland D.H.88 Comet which landed at 1701 hrs; fifth the Fulgur Breguet at 1737 hrs; then came the Bloch 160, but having started much earlier than the I-TOMO which arrived at 2002 hrs it was ranked seventh, while the I-TOMO was sixth. The others were all withdrawn or unclassified.

Final ranking in Paris
Pilots Aircraft Name Racing Number Qualified Average Speed
Biseo and Mussolini I-BIMU I-5 Third
Cupini and Paradisi I-CUPA I-11 First 350 km/h
Fiori and Lucchini I-FILU I-13 Second
Lippi and Castellani I-LICA I-7 Unqualified
Rovis and Trimboli I-ROTR I-12 Eighth
tondi and Moscatelli I-TOMO I-6 Sixth

On 29 August from 1500 hrs to 1530 hrs all the Corsa type planes and the I-MAGO, which had been brought to Paris to witness the triumph of the other S.M. 79 returned to Italy at the Littorio Airport.

From Damascus, however, on 22 August, the organization of the return of the I-LICA to Italy began. The plane was disassembled and the fuselage, engines, tailings and systems were recovered and sent to Beirut, Lebanon and embarked on a merchant ship bound for Italy. The wing, not transportable by road, and other material, was sold in Damascus.

The victory was celebrated in Italy as overwhelming as both the Savoia-Marchetti S.M. 79C and FIAT B.R. 20A were bomber aircraft adapted to racing aircraft while British and French aircraft were specially developed aircraft for air racing.

Despite the victory there were, especially abroad, those who criticized the planes, claiming that the Savoia-Marchetti S.M. 79C would not have been able to participate in the New York – Paris (race which was canceled in favor of Istres – Damascus – Paris).

The Decisive Test: Rome – Dakar – Rio

It was decided for various reasons to make a second record setting flight with the Savoia-Marchetti S.M. 79C. This was mainly to disprove some articles that appeared in newspapers and magazines of the sector of foreign nations that had stated that the S.M. 79 were:

“expressly built for a vain policy of prestige and therefore unsuitable for military uses, difficult to maneuver, excessively loaded, too delicate: in short, devices unable to withstand comparisons of practical use with similar foreign ones”

The French newspapers accused the Savoia-Marchettis saying that they could never win in a Paris – New York race due to limited range.It was also decided to test the possibility of transporting passengers and letters from Italy to South America with land based planes.The 3 S.M. 79Cs, I-BIMU, I-FILU and I-CUPA were taken and modified by SIAI-Savoia technicians, Direttorato Generale Costruzioni Aeree or DGCA (General Directorate of Aeronautical Construction) and the aeronautical military engineers.

The changes concerned the replacement of the propellers with the classic SIAI-Savoia propellers, a complete overhaul of the engines, an enlargement of the fuel fillers to reduce refueling time, improved radio, navigation aids, and autopilot.

The maximum take-off weight of the new version, now renamed Savoia-Marchetti S.M. 79T for Transatlantico (Transatlantic) was now nearly 14,000 kg, 3.5 tons more than the S.M. 79M.

After numerous test flights and tests carried up to December 1937, it was decided that the flight could be done.

The three aircraft were reassigned to different teams of pilots, Biseo and Paradisi took the I-BIMU now renamed I-BISE (MM. 359). Bruno Mussolini and Mancinelli took the I-FILU renamed I-BRUN (MM. 356) while Moscatelli and Castellani took the I-CUPA now named I-MONI (MM. 358).

On the morning of January 24th and at 0728 hrs, the three S.M. 79T took off from Guidonia airport for Dakar, the first leg of the Italy – Brazil.

The planes would have been in constant radio contact with Guidonia and Rio de Janeiro, periodically communicating their position.

At 0830 hrs the planes reported that they had flown over Capo Carbonara in Sardinia and at 0915 hrs they flew over Bona starting to fly over the mountains of the Saharan Atlas. At 1130 hrs the formation commander announced that he had slightly changed the planned route, turning north due to strong wind. At 1330 hrs the devices signaled strong wind with sand clouds and at 1530 hrs they communicated that they were within sight of the Atlantic at Villa Cisneros. At 1630 hrs they flew over Port Etienne and at 1745 hrs San Louis.

Landing in Dakar took place regularly at 1845 hrs Italian time. All navigation took place at an altitude ranging between 4,000 and 5,000 meters where the engines gave maximum power.

The actual distance traveled by the aircraft was over 4,500 km in 10 hours and 50 minutes, the average speed of 419 km/h.

After refueling in Dakar the I-BISE it’s ready to start the transoceanic flight. [modellismoitalia.altervista.org]
On the morning of January 25 at 0910 hrs (Italian time) the three planes left Dakar for Rio de Janeiro with a wing load of 220 kg due to the greater quantity of fuel and lubricant transported.

The navigation was done in close formation, which took place at an average altitude of 3,800 meters, but was disrupted in the central area of ​​the Atlantic by thunderstorms, headwinds, lightning and sudden showers of rain that forced the pilots to instrumental flight.

The I-MONI, due to a failure of the usual propeller, was forced to continue the flight with only two engines for 2,000 km of the crossing, significantly slowing its average speed to 312 km/h.

At 1730 hrs I-BISE and I-BRUN sighted the Brazilian coast and continued towards Rio de Janeiro, arriving at 2245 hrs at Dos Afensos airport in the midst of a crowd of people who arrived to celebrate the event.

Following a direct order from the commander of the I-MONI formation it headed to Natal where it landed at 1919 hrs for the necessary repairs. It should be noted that the plane could have made it to the finish line without any problems but the crew, tired from the crossing, preferred to land and repair the plane.

I-BISE and I-BRUN had thus completed an effective route of over 5,350 km (of which 5,150 km offshore) in 13 hours and 35 minutes at an average speed of 395 km/h.

The Rome – Rio de Janeiro connection took place within 39 hours and 17 minutes with 24 hours and 22 minutes of actual flight for an average of about 406 km/h on a route of 9.800 km. The I-MONI departed from Natal at 1158 hrs on January 28, and arrived regularly in Rio de Janeiro at 1742 hrs on the same day.

This showed that the Savoia-Marchetti S.M. 79 were not “too delicate” aircraft as foreign press had claimed, capable of reaching South America even with a failed engine.

Photos of the crew of the three S.M. 79T that had made the transoceanic flight. Compare the propeller cap with the photos of the S.M. 79Cs and you could clearly see the difference from the SIAI-Savoia propellers and the Ratier ones. [modellismoitalia.altervista.org]
It should be emphasized that the crossing was not a mere move by fascist propaganda, in fact, it was specifically chosen to lengthen the journey going from Dakar to Rio de Janeiro (5,350 km) instead of Natal (3,150 km).

Another factor was the speed, an average of 406 km/h for 9,800 km had never been sustained, in a single crossing the S.M. 79T broke two records, the speed one on the Rome – Rio de Janeiro route and the highest average speed one on the 5,000 km journey.

Brazil

After the 24 January 1938 race, the three S.M. 79 Transatlantico were then presented to the Aviacao Militar Brasileira (Brazilian Military Aviation). On 27 April 1938 I-BISE, I-BRUN were bought and renumbered K-422, K-420 while I-MONI was donated by Italy and renumbered K-421.

On 9 May 1938 they were assigned to the Escola de Aviacão Militar (Military Aviation School), where Maggiore Nino Moscatelli acted as instructor on at least three flights on 28 June (serial not reported) and then 1 July 1938 with K-421 and 8 July 1938 with K-420 before to returning in Italy acting as a bomber pilot.

On 28 October 1938 K-420 (Italian military serial number MM. 356) was flown by Brazilian pilot Loyola Daher, experienced an accident during a take off but luckily was later repaired, for it was recorded as flying in September 1941. The K-420 retired from service from the Escola de Aviacão on 12 February 1943.

On 9 July 1939 an unidentified S.M. 79T flown by Major Rubens Canabarro Lucas set a speed record by flying from Porto Alegre to Rio in 2 hours and 50 minutes at an average speed of 423 km/h (263 mph).

On 29 June 1943 was the last flight of an S.M. 79T for the Brazilian Air Line made by K-422 piloted by pilot Maldonado.

The service of the S.M. 79T as a training aircraft ended on 25 October 1944 when K-421 and K-422 were officially grounded by the Escola de Aeronautica.

Civil Service

The I-TOMO, I-ROTR and the reconstructed I-LICA aircraft were modified with a cabin for 4 passengers, the rest of the plane was used for cargo transport. They were used for the Rome – Rio de Janeiro route since 1939 by the Italian civil airline Linea Aerea Transcontinentale Italiana or LATI (Eng: Italian Transcontinental Airlines) part of the Ala Littoria.

The three aircraft, whose name does not seem to be clear since some sources call them Savoia-Marchetti S.M. 79C, others S.M. 79T and others S.M. 79I, were used mainly for the transport of mail on the route Rome – Seville (Spain) – Lisbon (Portugal) – Villa Cisneros (Morocco) – Ilha do Sal (Cape Verde) – Recife (Brazil) – Rio de Janeiro.

At least one was diverted to the Regia Aeronautica in June 1940 when the Kingdom of Italy joined the Nazi Germany in the Second World War. The aircraft, I-ALAN was requisitioned by the Regia Aeronautica and used to transport military equipment from Italy to Abyssinia (Italian name for Ethiopia) while maintaining its civilian livery.

Unfortunately only 6 days after the beginning of the war, on the 16th of June 1940 the I-ALAN had some problems during a take-off from Benghazi in Libya and was forced to abort the departure.

During re-landing the undercarriage collapsed and the aircraft crashed on the runway without causing too much damage and without casualties.

The aircraft, impossible to repair due to lack of parts, was moved to the side of the runway and probably cannibalized for spare parts to be used on other Savoia-Marchetti.

The carcass of the I-ALAN remained abandoned on the side of the runway of Benghazi for a long time and the British troops found it there in February 1941 when they conquered the Libyan city.

Not much is known about the other two aircraft, but they were probably used on the Atlantic route together with the Savoia-Marchetti S.M. 83 (civil version of the S.M. 79) and the Savoia-Marchetti S.M. 75.

At the beginning the crossing was carried out weekly: departure on Thursday from the Italian territory and collecting the Italian mail on the way, then, landing in the two Iberian countries, the Spanish and Portuguese mail was collected, arriving in Brazil, the Brazilian mail directed to the three European countries was loaded and the return journey was made.

After June 10, 1940, with the Italian declaration of war against France and the United Kingdom, the transatlantic flight had to be reduced to only one crossing per month. They were finally stopped on December 19, 1941 as a result of the entry into war of the United States, which controlled the Atlantic airspace and especially because the US government forced Brazil to break all diplomatic relations with Fascist Italy and therefore also to block the possibility of using their airports.

Camouflage and Markings

The planes were painted in a very flamboyant livery: Ruby Red with green and white lines.

The rudder had the Italian tricolor with the Savoia coat of arms in the center.

The lictor beams, symbol of the Italian Fascist Party, were painted on the engine cowlings, while on the fuselage, under the cockpit was written “S.M. 79. Savoia-Marchetti”.

In the center of the fuselage, the aircraft codes were written on the sides, inside a white rectangle with black borders.

Also on the sides were painted three green mice intent on laughing at each other, this was the symbol of 205ª Squadriglia da bombardamento “Sorci Verdi”, and in fact, in Italian, “Sorci Verdi” means green mice.

This symbol will then also be painted on the S.M 79M of the squadron during the Spanish Civil War and the Second World War.

On the Savoia-Marchetti S.M. 79T the livery was the same except for the codename written bigger without the white rectangle, and also because on the tail was added a small white rectangle with the codename of the aircraft during the first race.

After being delivered to the Aviacao Militar Brasileira, the aircraft were repainted green, with a yellow rudder. Brazilian serial numbers were then applied, painted in black on the sides and the “Brazilian Stars” on the wings.

The livery of S.M. 79C converted for civilian use was on an ivory white background with a blue line on the side.

Behind the cockpit was the inscription ‘ALA LITTORIA S.A. LINEE ATLANTICHE’, S.A. stands for “Società per Azioni” in English Joint-stock Company, the identification mark (in that case) I-ALAN and a Kingdom of Italy flag on the tail.
