SIAI-Marchetti traces its roots to the Societa Idrovolanti Alta Italia, founded in 1915 at Sesto Calende. The company became associated with the Savoia-Marchetti name through interwar aircraft production and later adopted the SIAI-Marchetti identity.
For this catalog, the most relevant SIAI-Marchetti line is the SF-260, a Stelio Frati-designed trainer and light-attack aircraft that Leonardo describes as having first flown and been certificated by Siai Marchetti before becoming an Aermacchi product in 1997.
The company was absorbed into larger Italian aerospace groups: Museo Agusta and Treccani document Agusta control from 1969, while Museo Agusta, Leonardo, and Volandia connect the later transfer/acquisition to Aermacchi in 1997.

SIAI-Marchetti is defunct and does not have a current standalone corporate website. The profile website points to Leonardo's official SF-260 background page because the cataloged aircraft line continued through Aermacchi, Alenia Aermacchi, and Leonardo.
