Britain, France, and South Africa used the Maryland.
495 Marylands were sold to France. 75 (140) of them were delivered before the fall of France in 1940.
The Marylands had only a loss rate of 8%, which was the lowest for a bomber in French service.
After the fall of France, many of these were transferred to the Royal Air Force and Royal Navy. Others went to North Africa to the Vichy.
Use in Battle of France
The GB I/62 and GB I/63 were equipped with the Maryland during the Battle of France.
After the fall of France the 60 Marylands that were left went to the Vichy forces in North Africa and Syria. Some of these were to be later used against the Allies.
The Royal Air Force (RAF) took over the 50 French Model 167Fs and named them the Maryland Mk I. The United Kingdom ordered 150 / 225 Maryland Mk IIs. 72 of these were sent to the South African Air Force.
Defense of Malta
The No. 431 General Reconnaissance Flight received the first Marylands in October 1940.
The Marylands provided the reconnaissance of Taranto Harbor before the Swordfish attacked the Italian Navy.
Bismark and Prinz Eugen
The Fleet Air Arm (FAA) used Marylands for reconnaissance and one of them reported the departure of the Bismark and Prinz Eugen in May 1941 from their port.
