The Defence Research and Development Organisation (DRDO) is creating a naval version of its indigenous Project Kusha long-range surface-to-air and anti-ballistic missile system. This maritime variant is designed to provide improved air defence capabilities to Indian Navy vessels, allowing them to counter a growing range of aerial threats at seaThe naval system is intended to intercept both low-altitude sea-skimming missiles, which are notoriously difficult to detect, and high-velocity anti-ship ballistic missiles (ASBMs), which can operate at high speeds during terminal approach. Combat engagement parameters include deflecting incoming weapons at speeds greater than Mach 7By preparing to repel threats at hypersonic speeds, the naval variant addresses one of the most deadly types of missile attacks. The ability to engage ASBMs during their terminal phase significantly improves capital ship survival rates in contested zones.
Sea-skimming missiles take advantage of radar blind spots by flying only a few meters above the sea surface, whereas ASBMs’ steep, high-speed drop makes interception difficultTo address these issues, the naval Kusha system includes modern tracking radars, high-energy missile interceptors, and rapid-response command systems.
The development is a direct response to regional rivals’ increasing deployment of ASBMs, such as China’s DF-21D and DF-26B series, which are capable of targeting large warships at long range. A locally created approach enhances India’s marine deterrence while minimizing reliance on foreign missile defenseOnce deployed, the naval variant is expected to become a core component of layered maritime air defence, complementing existing systems such as the Barak-8 and close-in weapon systems (CIWS) aboard frontline destroyers, frigates, and aircraft carriers.
