An intercooled cooling system (100) for a gas turbine engine (20) includes cooling stages (110,115) in fluid communication with an air stream (275) utilized for cooling. A first cooling stage (110) is fluidly coupled to a bleed port (145,165) of the gas turbine engine (20) to receive and cool bleed air with the air stream (275) to produce a cool bleed air. The intercooled cooling system (100) includes a pump (105) fluidly coupled to the first cooling stage (110) to receive and increase a pressure of the cool bleed air to produce a pressurized cool bleed air. A second cooling stage (115) is fluidly coupled to the pump (105) to receive and cool the pressurized cool bleed air to produce an intercooled cooling air. The intercooled cooling system includes an air cycle machine (190) in fluid communication to outputs of the cooling stages (110,115) to selectively receive the cool bleed air or the intercooled cooling air.
