India’s advanced next generation submarines, Scorpene data leak case has taken a big form. This is detrimental to Indian national security, even though government, navy and a bunch of old navy men think tanks would want to think otherwise. This leak also poses a threat to the commercial interests of French contractor DCNS, the manufacturer of these submarines. This could lead to questions being raised against standards of data protection in the firm. Their contract for manufacture of similar submarines in Australia is under lens as well.
