A unique airborne electrical power and thermal management system and a unique aircraft having a unique airborne electrical power and thermal management system are provided. The electrical power and thermal management system includes a turbine, which may power loads, for example but not limited to, a generator and a refrigerant compressor. The turbine may be in fluid communication with a gas turbine engine bleed air source to extract power from bleed air for powering the loads. A combustor may be fluidly disposed between the bleed air source and the turbine. The turbine may be part of a gas turbine engine distinct from a propulsion gas turbine engine. In one aspect, at least a portion of the electrical power and thermal management system may be disposed within an aircraft external pod. The pod may be configured to appear similar to a conventional external fuel tank pod employed by the aircraft.
