There have been estimated at least 109 F5 tornadoes in the U.S. Since the introduction of the Enhanced Fujita scale there have been 9 EF5 tornadoes, which is essentially equivalent to an F5.
Note that this number should be taken with a grain of salt as it can be difficult to distinguish between F4 and F5 damage, especially in records that must be evaluated based on historical accounts.
