A hybrid-electric propulsion system includes a motor drive and a rechargeable energy storage system electrically connected to the motor drive. The hybrid-electric propulsion system also includes a gas turbine engine operatively connected to the motor drive and the rechargeable energy storage system and an emergency power source operatively connected to the motor drive. A method for providing emergency power to a hybrid electric propulsion system includes determining whether one of an main engine power source and a rechargeable energy storage system are available for powering a motor drive. The method includes initiating a single-use emergency power source for powering the motor drive if the main engine power source and the rechargeable energy storage system are unavailable.
