The Macchi M.18 was an Italian-designed flying boat, created by Alessandro Tonini and manufactured by Aermacchi in the early 1920s.[1][2] Initially conceived as a passenger transport, it was ultimately produced as a bomber before later being marketed for civilian use, its original intended role.[1][2]
Design and development
Reflecting typical World War I design principles, the M.18 was a biplane flying boat featuring unstaggered wings of differing spans, supported by Warren truss-style bracing struts. The powerplant was mounted in a pusher configuration within the gap between the wings, while the pilot and observer occupied adjacent open cockpits. Additionally, an open gunner’s station was positioned at the bow.[2]
Alongside the standard military model, a variant with folding wings designated the M.18AR was developed for naval operations. This version served aboard the Italian Navy's seaplane tender Giuseppe Miraglia[2] as well as on the Spanish Navy's seaplane carrier Dédalo. The Spanish forces deployed these aircraft in combat against Moroccan insurgents.[3] Out of the twenty units acquired by Spain, six remained operational at the start of the Spanish Civil War, conducting attacks on Nationalist positions in Majorca and performing reconnaissance missions.[3] Portugal also procured eight examples in 1928 for their fleet.
In late 1932, Paraguay purchased two Macchi M.18ARs for its naval aviation branch, assigned serial numbers R.3 and R.5. These aircraft saw extensive deployment during the Chaco War (1932–1935), undertaking numerous bombing and reconnaissance sorties along the Northern Front. Notably, R.5 executed Paraguay’s inaugural night bombing mission on December 22, 1934. While R.3 was lost in an accident near the war’s conclusion, R.5 remained active until the mid-1940s.
Three civil variants were ultimately introduced.[1][2] The initial M.18 Economico (“Commercial”) closely resembled the military model; it was succeeded by the M.18 Lusso (“Luxury”), which incorporated an enclosed cabin.[2] The final version, M.18 Estivo (“Summertime”), returned to featuring open cockpits.[2] Approximately seventy civilian units were built,[1][2] with some acquired by sightseeing companies such as Switzerland’s Ad Astra Aero, while others were utilized by SISA to train flying boat pilots for airline operations over the Adriatic Sea.[2]
