na 6pdr i 17pdr APDS je uvedena 1944 godine
Citat:
The ultimate answer was the APDS shot, or Armour Piercing Discarding Sabot. This was similar to the APCR, except that the light-alloy sleeve was designed to break up and fall away from the shot as soon as it left the muzzle, so the velocity was sustained over a much longer range. The technical problems were considerable (and accuracy was never as good as with conventional shot) but, once solved, APDS became the standard tank AP ammunition until the development of the fin-stabilised round. The muzzle velocity of the 6-pdr tank/anti-tank gun rose from under 3,000 to over 4,000 fps with APDS; the succeeding 17 pdr APDS also hit nearly 4,000 fps, enough to penetrate even the 68-ton King Tiger tanks at 1,000 yards. The British 105mm L7 gun, optimised for APDS, became NATO's main tank gun through the 1960s and 70s, with a muzzle velocity of 4,800 fps.
