There have been NO new Purple Heart medals made since WW2. More than a million were ordered in anticipation of mass casualties had the US had to invade the Japanese Home Islands (other than Okinawa - which foretold the kind of hideous casualties that were to be anticipated if the invasion of the main islands were to be carried out. It's why the US dropped the A-Bombs). Thank goodness that the US military has not had that many casualties since WW2.
