With the wooden PT boats being easy to build, it was natural for many to become part of the Lend Lease program which provided equipment to America's allies. The separate article on PT Squadrons and their boats contain data on those craft which saw serive in both the American and and other Navies, including those boats which were built in the USA for direct use by other countries.
