Patriot vs S-300
MIM-104 Patriot
US air defense system, NATO standard, combat-proven
Proven ballistic missile and aircraft defense
S-300 (PMU-2)
Russian long-range air defense system, widely exported
Long-range area defense at lower cost
Short Answer
The MIM-104 Patriot is the US/NATO standard air defense system, combat-proven in multiple wars with PAC-3 MSE interceptors. The S-300 is Russia's workhorse long-range SAM, widely exported but with a mixed combat record. Patriot has better proven performance; S-300 has longer theoretical range.
Our Verdict
Patriot is combat-proven and continuously upgraded (PAC-3 MSE). S-300 has good specs on paper but an underwhelming combat record. Patriot has demonstrated kills against ballistic missiles; S-300 has not against a peer adversary.
