Era
Latécoère Late 21
The first flying-boat produced by Latecoere was the Late 21, built for Aéropostale for its Marseille-Algiers postal and passenger routes. The prototype, first flown in 1926, had a parasol wing with lower stub wings which acted as stabilising sponsons. Two 313kW Gnome-Rhone Jupiter 9Ab radials were mounted in tandem on the wing, and the single-step hull terminated in a large single fin and rudder. Open side-by-side pilots’ cockpits were located in line with the wing leading edge and there was cabin accommodation for seven passengers. Successful tests with the Late 21 led to the construction in 1927 of five slightly modified Late 21bis and a single Late 21ter, with Farman 12We engines. The Late 21 bis spanned 22.00m, had a maximum take-off weight of 5730kg and possessed a maximum speed of 172km/h.
The Late 23 was an enlarged version of the Late 21, powered by Farman engines and spanning 28.00m.

Latécoère Late 19 / Late 20
From the basic Late 15 design was developed the Late 19 twin-engined two-seat night-bomber, which dispensed with the lower stub wings and had open defensive machine-gun positions situated in the nose and amidships. Two were built in 1926 for the Armee de I’Air, as was the sole Late 20, an ambulance variant.

Latécoère Late 15
The first successful Latecoere design was the 1924 Late 15, the prototype being flown in 1924 and being followed by nine series aircraft. The Late 15 had a parasol wing spanning 18.00m and a lower stub wing, landing gear with twin-wheel main units, and power provided by two 230 hp / 194kW Lorraine 8-Bd engines. Accommodation comprised an open cockpit for the pilot, just forward of the wing leading edge, with a cabin for six passengers to the rear.
The Late 15s were operated on the Casablanca-Oran stage of the air routes flown by the Latecoere airline subsidiary. The Laté 15M were 5 a/c equipped with twin floats for the Alicante-Oran run. One Late 15 was temporarily redesignated Late 15H after float landing gear had been installed, but was soon restored to its original landplane configuration. The initial success of the Late 15 was shortlived as the aircraft was soon found to be underpowered.
