The Preparedness Plan (Russian: Gotovnost' Plana) was a plan instituted by the Russian Empire in 1939 as the threat of war with the Natso Alliance became apparent. The plan called for the production of 10,000 tanks, 7000 fighters and 5000 bombers in four years, as well as the trained crews to operate them. As well, production of modern rifles and artillery to re-equip the 1.9 million strong Standing Army, as well as new weapons for the 2.7 million Primary Reserve formations was given high priority. In 1940, with the fall of France, many factories and sometimes entire towns were moved to the east to protect them, though only about half the production slated to be moved was done so.
