Westinghouse Combustion Turbine Systems Division

The Westinghouse Combustion Turbine Systems Division (CTSD), part of Westinghouse Electric Corporation's Westinghouse Power Generation group, was originally located, along with the Steam Turbine Division (STD), in a major industrial manufacturing complex, referred to as the South Philadelphia Works, in Lester, Pennsylvania near to the Philadelphia International Airport. Before first being called "CTSD" in 1978, the Westinghouse industrial and electric utility gas turbine business operation progressed through several other names: Small Steam & Gas Turbine Division (SSGT) in the 1950s through 1971; Gas Turbine Systems Division (GTSD); and Generation Systems Division (GSD) through the mid-late 1970s.
