Project Kusha is a programme under the Defense Research and Development Organization (DRDO), for developing the Extended Range Air Defence System (ERADS), also referred to as XRSAM or PGLRSAM. The goal is to design a transportable, long-range surface-to-air missile system. The missile system will consist of at least three types of interceptors and is expected to be deployed by the Indian Air Force and Indian Navy by 2028–2029.
