The information was unveiled by the French company on its website on April 2 without disclosing the contract's value.
The 31-crew submarines have six launch pads, a capacity of 18 torpedoes and missiles and 12-day underwater autonomy, according to the company.
The two 72m submarines are set to be made in Indonesia, with the Naval Group transferring its technological know-how and the Indonesian side conducting related management, operation and maintenance.
The agreement will create thousands of long-term, highly skilled jobs, said the company./.
