A brief status review of the Advanced Launch System (ALS) is given. The use of electrical actuation integrated with a single-vehicle electrical power system and controls for all actuation and avionic requirements is highlighted. This technology will help attain the ALS primary goals of reduced costs ($300/lb Earth to LEO (low Earth orbit)) and improved operability by significantly reducing the launch operations and servicing requirements relative to current vehicle designs and practices. Six candidate government-supported programs that are involved in the relevant technologies or that could have significant applications for electric actuators and an integrated power-distribution and control system are listed with a brief explanation and description of noteworthy technology.<>
