No, but I have heard of a U.S. Attempt at a forcefield, I believe decades ago. I believe the original blueprints includes extremely accurate radar;
whenever any type of weapon was detected a weapon of equal or greater force would be fired in response and stop that weapon like a "forcefield".
These were a failure, but I doubt that has stopped the U.S. and other countries from continuing the efforts.
