Rudram-IV is designed to achieve hypersonic speeds exceeding Mach 5, a range of 1,000–1,500 km, and a lightweight design for integration with multiple IAF platforms, including the Sukhoi Su-30 MKI, Mirage 2000, and potentially the Rafale.
After Operation Sindoor, India has been working non-stop to upgrade its defense systems i.e. from missiles and drones to fighter jets and air defense technology. The Defence Research and Development Organisation (DRDO) is developing next-generation missiles that are far more advanced and deadly than before. Built with cutting-edge technology, these missiles can even dodge traditional radar and defense systems.
One of DRDO’s most ambitious projects is the Rudram program, under which it is developing the Rudram-4 hypersonic missile. This missile will travel at speeds of over Mach 5 (more than 6,000 km per hour) and will have a range of 1,000 to 1,500 km. This means that most parts of Pakistan would be within its reach.
Rudram-4 is considered one of DRDO’s biggest achievements
The Rudram-4 is considered one of DRDO’s biggest achievements so far. It is an air-to-surface hypersonic missile designed to greatly boost the strike power of the Indian Air Force (IAF). Its biggest strength is its incredible speed, which makes it almost impossible for conventional radars or defense systems to detect or intercept. Experts say that the missile gives the enemy only a few seconds to respond, making a successful hit almost certain.
Rudram-4 missile features
The Rudram-4 missile is being designed for pinpoint precision strikes. It won’t just suppress enemy air defense networks (known as SEAD) but can also completely destroy them (DEAD). Its strike power will be strong enough to take out enemy radars, bunkers, and communication hubs, targets that regular cruise or ballistic missiles often fail to destroy.
Early reports suggest that the Rudram-4 will have a strike range between 300 and 1,500 kilometers. It is expected to feature a dual-speed hybrid propulsion system starting with a solid rocket booster for the initial phase, followed by a scramjet or ramjet engine. This will allow the missile to maintain hypersonic speeds over long distances.
Its lightweight design makes it versatile enough to be mounted on different fighter jets. Initially, it will be integrated with the Sukhoi-30 MKI, but tests are also being considered for Mirage-2000 and Rafale aircraft. The lighter build will let aircraft carry more missiles, significantly boosting strike capability.
For accuracy, the missile is likely to use a combination of Inertial Navigation System (INS), GPS updates, and an Imaging Infrared (IIR) seeker in its final stage. This advanced guidance system will make the Rudram-4 capable of hitting targets even in heavily jammed electronic warfare environments.
Rudram-4 missile seen as next evolution of the Rudram series
The Rudram-4 missile is seen as the next evolution of the Rudram series, advancing beyond the Rudram-III. Unlike its predecessors, which were mainly anti-radiation weapons, the Rudram-4 will give India a full-fledged hypersonic strike capability. Together with the BrahMos supersonic missile and the upcoming BrahMos-II hypersonic project, Rudram-4 will help build a multi-layered strike system.
Defense experts believe this capability is crucial, especially with advanced air defense systems like China’s S-400 in the region. Global think tanks, including the Carnegie Endowment, note that India views such weapons as both a strong deterrent and a counterbalance against potential threats.
The Rudram-4’s development is closely linked to DRDO’s Hypersonic Technology Demonstrator Vehicle (HSTDV) program and its ongoing scramjet engine research. While the exact timeline for its operational induction remains classified, prototypes are expected to undergo testing in the coming years.
