Operation Sindoor: How is Russia's S-500 different from the S-400 defence system?

In the wake of heightened regional tensions, especially after Operation Sindoor, missile defence has become a core concern. Post the success of Russian-made S-400 in repelling aerial threats during the operation, discussions abut next-generation systems—especially the upcoming S-500 Prometheus have started. Here is an in-depth comparison on how S-400 and the upcoming S-500 are different.

The S-400 has a maximum interception range of about 400 km and has the ability to detect threats up to 600 km away, while the S-500 air defence system pushes that envelope significantly. It can engage aerial targets up to 800 km away and ballistic missiles as far as 600 km, with detection capability stretching up to 2,000 km.

The S-400 is effective at intercepting threats up to 30 km in altitude. The S-500 extends its reach to near-space with interception capabilities up to 200 km, this further allows it to counter low Earth orbit satellites and high-trajectory ballistic missiles.

The S-400 defence system is not specifically designed for hypersonic threats or space objects. However, the S-500 is built to neutralise hypersonic missiles travelling at speeds close to Mach 20, and even space-based platforms. Hence, it marks itself as a response to newer and faster threats.

The S-400 uses a mix of 40N6, 48N6, and 9M96 series missiles, with speeds up to Mach 14. The next generation S-500 introduces advanced interceptors like the 77N6 series which are capable of hit-to-kill precision at greater ranges and speeds—up to Mach 20.

The S-400 has the ability to track 80 and engage 36 targets simultaneously with a response time under 10 seconds. The S-500 on the other hand, engages up to 10 targets at hypersonic speeds but with a faster response time—under four seconds.

S-400 is operational in countries including India, China, and Turkey. S-500 is still being inducted by Russia and is expected to see wider deployment in coming years. India has shown interest in potential co-development.
