The JO3C (Joint Operations Configurable Combination Cart) provides power and air to multiple aircraft platforms. It follows a modular design concept that allows flexibility to select required cooling and power outputs for multiple aircraft platforms. Power modules can be removed and used as stand-alone units. Options include 400 Hz converter, 270 VDC converter, 28 VDC converter, servo air, diesel or electric powered (or both) and a lighting package. The power quality exceeds MIL-STD-704E and F-35 standards. The unit is transportable on a single C-130 pallet position.
