Is Boxer the vehicle still suffering from serious vibration problems?
Short answerAjax is the programme associated with those vibration problems. Boxer has a separate development and procurement history.
NotesAjax is the programme associated with the vibration problem raised in the question. Britain originally joined Boxer, withdrew to pursue another vehicle, and later returned after the alternative produced no vehicle. By then, it was buying Boxer from Germany. These are separate procurement histories, despite their overlap in criticism of British Army equipment programmes.
