This paper presents the results of a systems analysis which examines the potential for advanced propulsion technology to enable a family of modular expendable launch vehicles. By combining strap-on boosters with a high energy core vehicle, payload capability to low earth orbit (LEO) can be extended to a range from 40000 pounds to over 150000 pounds. In this study a new two stage core vehicle is sized to deliver 40000 pounds to LEO, assuming an easterly launch. Payload enhancement is achieved by adding two or more strap on boosters. Core vehicle configurations that were studied include storable, hydrocarbon, and hydrogen fuels. Boosters studied a similar set of liquid propellants as well as hybrid and solid fuel options. Gross LIft Off Weight (GLOW), inlet weight, and payload capabilities are assessed.
