STRATEGIC BOMBERS OF BETWEEN THE WARS:  1918-1939.  The period between the World Wars saw rapid development in aviation technology, translating into the capability to carry heavier bomb loads further distances, moving military aviation into truly strategic reach with destructive power sufficient to significantly damage infrastructure, industry, and population centers.

General Notes To All Tables:  Aircraft listed below, in some cases, served in the air forces of a variety of countries or may have only been built for export.  Dates for these aircraft reflect their service as bombers in squadron service in all variants (not necessarily the variant for which data is provided), although they may have continued in service past these dates in other roles (for example, as transports, maritime patrol, glider tug, etc.).  Dates may reflect service in other air forces beyond squadron service in the manufacturing nation's air force.  Speed unless otherwise listed is cruise speed.  Ceiling unless otherwise listed is service ceiling.  Range data is subject to great variation based on load, altitude, and speed and should be taken only as an approximate measure of maximum flight distance, not as an operational radius within which aircraft could execute attacks.
