New Delhi (Sputnik) — India’s scorpene class submarine project has been left high and dry due to delays in the development of indigenous vital components of the Air Independent Propulsion (AIP) system by the Defence Research and Development Organisation.
"We will do it as a retrofit," says Vice Admiral G S Pabby, Controller of Warship Production and Acquisition, Indian Navy.
This can be retrofitted into old ships to enhance the survivability of the submarines. It uses a limited amount of stored liquid gas which ultimately is used to charge the sub's battery, increasing the time they can spend down below. Otherwise, submarines have to come back to surface to charge their batteries.
The Indian government has also not been unable to find a heavyweight torpedo for the submarine. Manohar Parrikar, India’s Minister of Defense had directed officials to search for an alternative to the Black Shark Torpedoes in May this year due to the manufacturers’ parent company's involvement in the 556 million euro VVIP AgustaWestland Helicopter bribery case. Black Shark Torpedoes were to be an essential part and primary weapon of India's six new scorpene submarines.
India is building six scorpene class submarines at cost of $3.5 billion under Project 75 which is already delayed by four years.
