Defence Ministry Inks Contracts for AIP Modules and Heavy Torpedoes for Scorpene Submarines

The Indian Ministry of Defence has recently signed two contracts valued at ₹2,867 crore concerning Scorpene-class submarines. The contracts focus on enhancing the operational capabilities of these submarines through advanced technologies.

Contracts Overview

The first contract, worth approximately ₹1,990 crore, involves the construction and integration of an air independent propulsion (AIP) module. This module is developed by the Defence Research and Development Organisation (DRDO) and will be integrated by Mazagon Dock Shipbuilders Limited in Mumbai. The second contract, costing about ₹877 crore, pertains to the integration of an electronic heavyweight torpedo (EHWT), which is also being developed by the DRDO in collaboration with Naval Group, France.

What is Air Independent Propulsion (AIP) Module?

• AIP is a propulsion system that allows conventional submarines to remain submerged for extended periods without surfacing.
• It enhances endurance, stealth, and operational capabilities of the submarines.
• The DRDO’s AIP module is expected to be fitted onto Scorpene submarines, with the first submarine, Kalvari, scheduled for refit in 2025.
• The integration of the AIP module is projected to generate nearly three lakh man-days of employment.

What is EHWT?

1. • Electronic Heavy Weight Torpedo (EHWT), also known as the F21 Heavy Weight Torpedo, is a state-of-the-art weapon system developed with advanced aluminum silver oxide technology.
   • The integration of EHWT into the Kalvari-class submarines will be a collaborative effort involving:
     • Indian Navy
     • DRDO (Defence Research and Development Organisation)
     • Naval Group, France
   • The use of aluminum silver oxide technology improves the torpedo’s range and allows for much higher speeds, making it a more lethal weapon compared to conventional torpedoes.
   • The integration will significantly enhance the firepower capabilities of the Kalvari-class submarines, boosting their operational efficiency and combat potential.

Future Developments

The fitment process for the AIP module is anticipated to take two to three years, expected to be completed by 2027 or 2028. This timeline marks step towards enhancing India’s submarine capabilities and overall naval strength.

GKToday Notes:

1. AIP Module: The Air Independent Propulsion module enhances submarine endurance. It allows prolonged submersion, improving stealth. Developed by DRDO, it represents technological advancement for Indian naval capabilities.
2. EHWT: The Electronic Heavyweight Torpedo is a modern weapon system for submarines. Developed by DRDO, it addresses previous procurement issues. Its integration marks a collaborative effort with the Indian Navy and France.
3. Kalvari: Kalvari is the first Scorpene-class submarine of India. Scheduled for a refit in 2025, it will undergo upgrades. This includes the integration of advanced technologies for enhanced operational capability.
4. Mazagon Dock Shipbuilders Limited: Located in Mumbai, this shipbuilding company constructs naval vessels. It plays important role in India’s defence sector. The company is involved in integrating advanced submarine technologies.
