The '''Loire 70''' was a 1930s [[France|French]] long-range maritime reconnaissance flying boat produced by [[Loire Aviation]].
 
==Design and development==
[[File:Loire-70 mg 7862.jpg|thumb|leftright|Wind tunnel model of the Loire 70]]
The Loire 70 was designed to meet a 1932 [[French Navy]] requirement for a long-range flying boat for [[Surveillance aircraft|maritime reconnaissance]] and [[Bomber|bombing]]. The prototype first flew on 28 December 1933.<ref name="green v5">{{cite book |last= Green |first=William |title=Warplanes of the Second World War, Volume Five, Flying Boats |year= 1968|publisher= Macdonald|location=London|pages= 6–9 |isbn= 0-356 -01449 -5 }}</ref> It was an all-metal [[monoplane]], with a heavily braced high wing, with three [[radial engine]]s mounted above the wing, two as tractors and one as a pusher. The original engines, three 500&nbsp;hp (373&nbsp;kW) [[Gnome et Rhône|Gnome-Rhône 9Kbr]] 9Kbr radials, were not powerful enough and were replaced with 740&nbsp;hp (552&nbsp;kW) Gnome-Rhône 9Kfr radials. Seven production aircraft were produced.
 
==Operational history==
The seven production aircraft and the prototype were all delivered to the French Navy, serving with ''Escadrille E7'' at [[Karouba]] in [[Tunisia]]. During the early days of the [[Second World War|war II]], the aircraft carried out patrols in the Mediterranean. In an [[Aeronautica Nazionale Repubblicana|Italian]] air raid on their base on 12 June 1940, three of the four surviving aircraft were destroyed.<ref name="green v5"/> ItThe isremaining notLoire known70 whatwas happenedone toof thea lastnumber of aircraft that were requested to be scrapped on 4 October 1941.<ref>Bousquet May 1992, pp. 53, 55</ref>
