Societa Idrovolanti Alta Italia (Seaplane Company of Upper Italy) was formed in 1915. Its first notable success was an S.12 that won the 1920 Schneider Trophy. Ing. Marchetti joined the company in 1922. His seaplane designs saw further success and established the company's growing reputation, particularly the incomparable S.55. Although re-named Societa Italiana Aeroplani Idrovolante in 1936, it was to become a major builder of large land-based transport and bomber aircraft instead. The S.79 Sparviero is perhaps their most celebrated, being Italy's most famous and popular WWII aircraft.

Savoia S.55. This iconic double-hulled flying boat captured the public imagination after the epic 1931/1933 Decenalle flotillas to North America, led by Gen. Italo Balbo. A highly successful publicity campaign and a hugely impressive achievement for the time. Earliy versions of the S.55 did see service as part of the Regia Aeronautica. The Delta2 S.55X kit was the only S.55 to appear in 1/72 but, unfortunately, was a very crude toy-like model, needing a lot of work to bring it up to today's standards. If there was ever an Italian aircraft that needed to be well represented in model form, it has to be this one and, happily, Dora Wings have released an all new 1/72 injection moulded kit. It is a vast improvement over the Delta2 kit. It appears to be a very well researched model that is loaded with accurate, nicely detailed parts. It is not known if they will be releasing a ‘X’ version, as used for the Decenalle flights.

Savoia Marchetti S.74. In its heyday, this 25 seater 4-engined airliner, flown by Ala Littoria, was one of the fastest passenger planes in service. Only 3 were made and all were commandeered by the Regia Aeronautica for transport use in the North Africa campaign. All were destroyed during service. Broplans 1/72 vacuform kit is quite easy to assemble thanks to the thin gauge plastic sheet, but the rear fuselage section is not very well designed. One fault shared by other Broplan kits is the poor quality cowling and engine detail. If possible they should be replaced. SEM Models have two SM.74 1/72 resin kits in their range in either the Ala Littoria or Regia Aeronautica markings.

Savoia Marchetti SM.75. Used extensively by the Ala Littorria civilian airline, most if not all were commandeered by the RA for transport use. It was from this aircraft that the SM.82 was developed. Broplan isssued three versions of this aircraft. Italiankits released a SM.75PD conversion to be used with the Italeri SM.82 kit as have SEM Models.

Savoia Marchetti S.M.78 is a medium sized 1930’s maritime biplane, but did not see widespread service due to the Cant Z.501 entering service at the same time. Choroszy Modelbud’s 1/72 resin kit is well worth considering, as are most products from this company. They are usually very well moulded, if a bit fiddly.

Savoia Marchetti S.79 Considered to be Italy's most historic and important WWII aircraft, it became a major morale booster for the Italians after repeated success as a torpedo bomber. It remained in full production throughout the war. It acquired the unofficial nickname of ‘Maledetto Gobbo’ (Damned Hunchback). Somewhat inexplicably, this aircraft was poorly presented in model form for some time. For a while only, the only worthy kit was the all resin 1/48 resin model from E.P.Originals (Vintage Models re-released it with a few extras at one time). Other kits included the inaccurate Airfix 1/72 kit and the very poor 1/48 SMER (ex-Artiplast). This situation was resolved with a series of Classic Airframe 1/48 limited run releases, covering both the early bomber and late torpedo versions. ItalianKits produced 1/48 & 1/72 Corsa conversion sets which included decals printed by Cartograf. Flashback re-issued the Classic Airframe kit as a limited run kit, with additional Eduard brass etch and resin parts. At more or less the same time, Trumpeter issued a 1/48 model. It is a worthy effort, but it is not quite to the same standard set by Classic Airframes. There is a very strange, over-scale fabric effect on the fuselage & tail surfaces. Cockpit detail is poor by comparison and the cowlings are not quite the right shape, nor are the stabilisers. One bonus of this model is the separately moulded control surfaces. A very welcome development were the 1/72 S.79 kits from Italeri, covering all major variants. As hinted at by the quality of their Macchi C.202 & 205 models, they are quite nicely detailed and are relatively easy to assemble and, in view of its relatively cheap price, they are also excellent value. This will enable multiple purchases to attempt some of the wide variety of schemes used on this aircraft. ItalianWings produced a SM.83 conversion for the old Airfix S.79 kit which could work on the Italeri kit. Pavla have also released a Corsa conversion, but requires surgery to the Italeri fuselage (the ItalianKits set includes a complete fuselage). One other interesting release is the Jumo powered S.79 by 1/72 Azur/Fromm, a variant that was built for the Romanian airforce. Needless to say, there are plenty of other after-market items for the S.79, including many conversion sets by Italiankits.

Savoia Marchetti SM.81. Italeri have re-released Supermodels SM.81 kit with improved, engraved panel lines and fabric detail. Falcon produced replacement canopy parts that can further enhance its overall appearance. For the Alfa Romeo engined version, the engine should be replaced by more accurate aftermarket versions as the kit parts are rather generic. Old Wings produced a resin conversion to an SM.73 and Tauro provide details on their Ala Littoria decal sheet on how to convert the Italeri/Supermodel kit.

Savoia Marchetti SM.82. One the finest purpose built transports of WWII. The Germans commandeered about half for use in the Luftwaffe. Based on the SM.75 airframe, the concept was the brainchild of Italo Balbo. Italeri have produced a 1/72 kit and is definitely worth adding to any Regia Aeronautica model collection. However the flaps and bomb bay doors are tricky to assemble in the closed position and the cowls are rather poorly shaped.

Savoia Marchetti SM.84. The SM.84 was to be the replacement for the S.79 but it was unpopular with its crews. Therefore the S.79 remained in service with the SM.84 used in a supporting role. Now OOP, the Aviation USK model was a decent enough kit, although not without the usual limited-run shortcomings. It has hardly any interior detail, although it doesn't matter really as all the windows are very small. The cockpit canopy comes in two halves which require careful assembly in order to get a good smooth join. The engine cowlings are a bit tricky to align. The decals are very nicely printed and Skymodels have produced additional markings. Jean Barby’s expert build of Alitalianes ambitious 1/48 resin kit, now OOP, can be seen on the stormomagazine website. SEM Models currently have a 1/48 resin in their catalogue but it is pricey.

Savoia Marchetti SM.85/86. The S.M.85 was Italy's only dedicated dive bomber design to have made it into service, albeit unsuccessfully... all were written off by 1941. RCR produced a 1/72 resin SM.85 and Alitaliane produced one in 1/48 scale. Both are OOP. LF Models issued 1/72 S.M.86 & SM.86W variants, both prototypes based on the SM.85, which were powered by Delta and Walter engines respectively.

Savoia Marchetti SM.87. A floatplane version of the SM.75 that saw service as a passenger plane by Ala Littoria. Only 4 built. Broplan released a 1/72 vacform model that was based on their SM.75 kit with the addition of floats and different engine detail. Aerofan #98 features an article on this aircraft.

Savoia Marchetti SM.89. A twin-engined prototype derived from the SM.84 trimotor, powered by Piaggio P.XII RC35 radials. Italiankits released a 1/72 resin kit of this aircraft under their Italian Wings label.

Savoia Marchetti SM.93. This is another one of Italy's dive-bomber prototypes, this one being somewhat unusual in that the pilot lay prone to prevent blackouts when pulling out of a dive. Tested by the Luftwaffe but abandoned in 1943. Legato issued a 1/72 resin kit but needed corrective work to get a accurate appearance. Aerofan #93 features an article on this aircraft.
