What I am trying to find out is if it has any capacity to fire at a sustained rate. Obviously it doesnt have a million rounds but does it even have a thousand?

It's a prototype.

"The reason for the 36 barrels was simply to indicate to ourselves and to others the future versatility of this system, in that with the 36 barrels we had 540 rounds on board and, based on the 45,000-round-per-minute rate per barrel, that gave us a maximum firing rate of 1.62 million rounds per minute," the inventor says. Prior to Bertha's well-deserved retirement, O'Dwyer used the demonstrator to achieve a 180-round burst of 9mm rounds (155 grain weight) at a rate of just over 1 million rounds per minute.
