K-4 Missile Features

• The 12-metre-long missile weighing 17 tonnes has a two-stage solid-fuel system. 
• It has a range of around 3,500 km. It is a major improvement over the older K-15 missile, which had a much shorter range of only 750 kilometers.
• Payload: Up to 2 tons, including a nuclear warhead.
• One of its key features is its ability to be cold-launched from underwater, which allows the missile to be ejected from the submarine before the engine ignites.
• It is guided by an advanced inertial navigation system supported by GPS and India’s NavIC system.
• This combination ensures high accuracy, with a reported circular error probable of less than 10 metres. 
• The missile is also equipped with manoeuvring features that help it evade missile defence systems.
