Global Rank: #1 in hypersonic development.
Defense Budget: ~$300 billion (2nd highest globally).
4. Israel – Iron Dome, David’s Sling & AI Command
Israel may be small, but when it comes to defensive tech, it’s miles ahead.
-
Iron Dome: World-famous for intercepting short-range rockets with pinpoint accuracy — especially used during sudden regional conflicts.
-
David’s Sling & Arrow-3: These extend the shield to handle medium- and long-range threats.
-
AI-Based Warfare: Israel’s use of real-time analytics in defense response is unmatched.
Global Rank: Top 3 in missile interception success rate.
Searched For: “Iron Dome working system”, “best anti-rocket system in the world.”
5. India – S-400, Agni Missiles & INS Arihant
India is building a strong three-pronged defense: land, air, and sea — especially with China and Pakistan in its neighborhood.
-
S-400 Systems: Recently inducted from Russia, boosting India’s air defense game.
-
Agni-V Missile: Intercontinental ballistic missile (ICBM) with a 5,000+ km range. Nuclear-capable.
-
INS Arihant: Nuclear-powered submarine giving India 2nd strike capability.
