Abstract : The need to launch large payloads (65,000 to 190,000 pounds or greater) into easterly LEO, payloads in excess of 65,000 pounds into near-polar LEO, and payloads over 15,000 pounds into GEO within the relatively near future has resulted in a joint USAF and NASA program to develop an Advanced Launch System (ALS) which will meet the required lift capability. The general concept of the ALS is for a liquid-fueled (liquid oxygen LO2/liquid hydrogen LH2 core vehicle with strap-on boosters added to increase payload lift capability. Boosters being considered include expendable liquid fueled (LO2/LH2) boosters, recoverable flyback liquid boosters, and solid propellant rocket boosters (SRB).
