3:26 A JDAM bomb or a Joint Direct Attack Muniton bomb is a kit that is assembled onto un-guided bombs, like the ones dropped from planes, to convert them into Precision Guided Munitions (PGM) or just simply "guided bombs." The kit can convert loads of around 200 to 900 kg. And yes that can include some strat warheads, usually on the lower side though.
