In a groundbreaking advancement for submarine warfare, Thyssenkrupp Marine Systems (TKMS) and Diehl Defence have joined forces to develop the Interactive Defence and Attack System (IDAS). This cutting-edge technology allows submarines to defend themselves against airborne threats without needing to surface, thus preserving their stealth. This development has significant implications for navies worldwide, including India's, which is in the process of modernizing its submarine fleet.
Traditionally, submarines have been vulnerable to attack from aircraft and helicopters equipped with anti-submarine warfare (ASW) capabilities. To counter such threats, submarines were forced to surface, compromising their position and making them susceptible to further attacks. IDAS changes this dynamic by enabling submarines to neutralize aerial threats while remaining submerged.
The IDAS utilizes the submarine's existing torpedo tubes to launch a fiber-optic guided missile. This missile can be controlled from within the submarine, allowing for precise targeting and even mission abort if necessary. The technology is based on the proven IRIS-T air-to-air missile system, adapted for underwater launch and operation.
India recently selected TKMS, in partnership with Mazagaon Dock Shipbuilders Limited (MDL), for its Project-75I program to build six advanced submarines with air-independent propulsion (AIP). The potential integration of IDAS into these submarines could significantly enhance their defensive capabilities and survivability.
IDAS is a "globally unique technology" that is expected to be available to various customers of TKMS and Diehl Defence. This system could revolutionize submarine warfare by providing an active defence mechanism against aerial threats, making submarines less vulnerable and more effective in modern combat scenarios.
Germany to Debut IDAS on its Type 212CD Submarines
The German Navy is also investing in IDAS, with the system slated to be integrated into their new Type 212CD submarines. The German parliament recently approved a significant financing package for these submarines, with a portion dedicated to completing the development of IDAS.How IDAS Works
The key to IDAS lies in its ability to launch a missile from a submerged submarine and maintain control throughout its flight via a fiber-optic link. This link enables real-time data transfer, allowing the submarine crew to monitor the missile's trajectory, adjust its course, confirm targets, and even abort the mission if required.The process begins with the submarine detecting an aerial threat using its sonar. The target data is then relayed to the operator's console, and the missile is launched from a torpedo tube. The missile travels underwater towards the target and surfaces before engaging its booster and wings for flight. Throughout this process, the fiber-optic link provides the submarine crew with continuous updates and control over the missile.
IDAS for India?
Several countries, including India, have expressed interest in acquiring IDAS. With India's recent selection of TKMS for Project-75I, the possibility of incorporating IDAS into these submarines is a significant development. The Indian Navy has been seeking to modernize its submarine fleet, and IDAS could be a valuable asset in addressing the growing challenges in the Indian Ocean Region.While the acquisition of IDAS by India is yet to be confirmed, the potential integration of this revolutionary technology could significantly bolster the Indian Navy's submarine capabilities and enhance its operational effectiveness in the face of evolving threats.
