JAJ - you are quite correct that the range and accuracy on the 27mm is often overlooked. Even on the GR1 we 'ceased' at a similar range as the Aden users 'opened'. The velocity at the target was similar to what the Aden achieved at the muzzle. It really was a step-change in capability and poorly understood by those who only knew the old 30mm Aden.
