Avro Lancaster - French users

Fifty-nine Avro Lancasters were overhauled by Avro at Woodford and Langar and were delivered to the French Aéronavale because due to the common defence treaty of the Western European Union, they could have them for training, anti-submarine wars and sea patrol between 1952/1953 (when they were delivered) until 1962. They served in two key locations of French colonies, New Caledonia and French North Africa.
In New Caledonia they served with four squadrons performing search-and-rescue and reconnaissance missions. They were painted white because most of the belonged to the B.Mk.I (FE) variant.
An anti-submarine and patrol squadron was based in Morocco, at the French aeronaval base of Port-Lyautey, in Kenitra. They served until 1960 when they were replaced by the Lockheed P-2 Neptune.
There was also another Lancaster squadron based in Agadir, Morocco, that was also equipped with Lancasters during 1961/1962 when that city suffered a vicious earthquake.
