Description	This report is a presentation reviewing the external tanks which are used to provide the propellants for the space shuttle engines. The design of the external tank, and its lift capability improvements are reviewed. The configuration, materials, and key technologies of the super lightweight tank (SLWT) are also described. Among the key technologies which allow the SLWT project to succeed, are the successful development of an appropriate alloy. The reasons for choosing the alloy, Aluminum-Lithium 2195, and issues involved in welding are reviewed. Tests of the weld procedures, and pictures of the test results are shown. The External Tank Project has successfully made the transition from the LWT design to the SLWT design. The SLWT Provides two thirds of the weight savings required to place the Space Station in a 51.6 Degree Orbit.
