The Central Bureau of Investigation will question former defence minister George Fernandes and former naval chief Admiral Sushil Kumar in connection with Barak missile deal.
The questioning will take place soon, CBI sources said.
Both Fernandes and Kumar have been named in the FIR filed by the agency for allegedly ignoring the Defence Research and Development Organisation's opinion on purchase of Barak missile from an Israeli company.
The deal had been struck during the previous National Democratic Alliance rule.
