Proper Air Force term for the glorious wonder is "Jammer" M1 and M2s when I was in, They are cantankerous and have more pinch points than a B- 52. engines are loud and knock quite frequently, probably because every weapons TOAD and crew chief ( sic Nose Picker) abused them as they beat them across the flight line , they are out there, BUT, AF never lets one go until it is absolute garbage
