Yes, and what a weapons system in its' day.
Will always remember the reaction of the crowd at a firepower demo in Epi Bay - the pair of polystyrene rafts had already been attacked by Buccs with BL755 when we went down the dive as a pair in line abreast each firing 300 rounds of 23mm ball from the SUU-23. 6000 rounds per minute each picked both rafts out of the water, spun them around and left little bits floating.
Also the Skywatch demo for the BBC on Salisbury Plain when our leader loosed off a long burst into the MT coach primed with petrol.
The odd Skyflash firing off a QRA scramble proved quite reassuring too - in those days we had a weapons system that worked almost straight out of the box. Never catch on!
