This would be a cluster of four 150 kW thrusters. By
far the largest electric propulsion system ever to be
developed. I can't find any data describing the exact
thrust level or Isp.

It would be used on future cargo vehicles to the Moon
and Mars, and no doubt large planetary probes.

I want to see the power supply. One megawatt solar
arrays don't come cheap or compact.
