Mazagon Dock Shipbuilders Limited (MDL) is set to submit a price bid next month for the construction of three follow-up Kalvari class submarines equipped with an indigenously developed Air Independent Propulsion (AIP) system. This advanced propulsion system is expected to significantly enhance the underwater endurance of the submarines.

The Indian Navy has already issued a letter of intent (LOI) to MDL for the procurement of these three submarines. The LOI also calls for increased indigenization of critical components and the replacement of obsolete systems. The estimated cost of each submarine with the AIP system is around $1.2 billion, bringing the total value of the project to approximately $3.5 billion.

MDL is optimistic about the prospects of securing the contract and hopes to conclude negotiations by next year. If the contract is awarded, work on the submarines is expected to commence in 2025. All three submarines are scheduled to be delivered within five to six years of contract signing.

The AIP system is a crucial technological advancement that will extend the underwater range and operational capabilities of the Kalvari class submarines. This system allows the submarines to operate while submerged for extended periods without relying solely on batteries, significantly reducing their need to surface for refuelling.

The increased indigenization of critical components for these submarines aligns with India’s strategic goal of self-reliance in defence manufacturing. By utilizing domestically produced components, India can reduce its reliance on foreign suppliers and strengthen its domestic defence industry.

This project represents a significant step forward in India’s efforts to modernize its naval capabilities and enhance its maritime defence posture. The AIP system, coupled with increased indigenization, will further strengthen India’s position as a major naval power in the Indian Ocean region.
