Can any Brit on this site tell me when the Americans obtained the right to manufacture Chobham Armour.Did you not retain something? did they buy it or was it just given? Apparently the Sth Korean K1 MBT has the British Armour made in the U.S. How stupid is that? giving your competitor the main thing that seperates the Abrams and Challenger. The Challenger thus far has the better service record a lot of that is due to the chobham armour.
