The '''Macchi M.12''' was a [biplane](/source/biplane) [flying boat](/source/flying_boat) [bomber](/source/bomber) designed by [Alessandro Tonini](/source/Alessandro_Tonini), and produced in small numbers by [Macchi](/source/Aermacchi) in [Italy](/source/Italy) in 1918.<ref name="JEA">Taylor 1989, 617</ref> 

==Design and development==
The M.12 had a conventional design, generally similar to an enlarged version of other Macchi designs of the period, and featured the [Warren truss](/source/Warren_truss)-style [interplane strut](/source/interplane_strut)s that had been introduced on the [Macchi M.9](/source/Macchi_M.9).<ref name="JAWA 19 390">''Jane's All the World's Aircraft 1919'', 390</ref> A major difference however, was its [twin-boom](/source/twin-boom) [fuselage](/source/fuselage),<ref name="JEA" /> each with a separate tailfin.<ref name="JAWA 19 390" /> An M.12 was entered in the [Schneider Trophy](/source/Schneider_Trophy) race of 1920, but did not compete.

The '''M.12''bis''''' was a civil variant with five seats and a wingspan extended to 18&nbsp;m (59&nbsp;ft), intended to carry passengers and mail.<ref name="JAWA 19 391">''Jane's All the World's Aircraft 1919'', 391</ref>
