Singh, who will head Tata Advanced Systems Ltd (TASL), joined the Tata group in 2003, and was a Director of TASL.
The appointment comes just weeks after it teamed up with Airbus Defence and Space, a division of Airbus Group, to bid for Indian Air Force's multicrore transport aircraft replacement programme.
Singh has led a range of new business opportunity development that required leveraging cross-linkages between multiple Tata companies in new geographies and new industries, among them aerospace and defence, sources in Tata said.
TASL's business scope includes aerospace, missiles, radars, unmanned systems, command and control, optronics and homeland security.
It has partnership with global original equipment manufacturers (OEMs) including Sikorsky, Lockheed Martin, Pilatus Aircraft, Cobham Mission Equipment and RUAG Aviation for their global requirements.
The Tata group has identified aerospace and defence as a focus area.
