Italian authorities are carrying out separate investigations into the alleged bribery scandal involving the supply of 12 VVIP choppers to India under a deal which has already been scrapped by the Defence Ministry.
The Italian prosecutors have sought the jail terms for Orsi and Spagnolini in an Italian court in Milan, according to Italian media reports.
The two officials have denied allegations of any wrongdoing against them.
The reports suggested that the Indian side also joined the Italian prosecutors in demanding conviction of Orsi and Spagnolini.
