1. BrahMos is very “famous” around the world. It is famous for its extremely poor reliability and low accuracy. According to NATO and Chinese military weapon system standards, it is a product that should have been phased out long ago.
2. India can only produce simple components and perform final assembly for BrahMos. They cannot produce the engine and guidance system. These components come from Russia. However, Russia cannot mass-produce these components either. Therefore, you can assess how many BrahMos missiles India actually possesses.
@Oscar has already explained the situation to you.
3. Years ago, Pakistan raised concerns with China regarding the BrahMos missile. China developed the CM-400 AKG based on an improved version of the YJ-12. It is much smaller than the BrahMos but has significantly higher reliability and accuracy. The Pakistan Air Force (PAF) has already purchased some CM-400 AKGs.
