Patriot has HOT launch system.
HOT launch system provide good results (vs. Cold launch system), but it is possible for a missile to malfunction and explode during HOT launch process (rare but happens).
On 16-05-23, Russia subjected a Patriot battery stationed somewhere in Kyiv to a very complex and deadly airborne assault composed of drones, cruise missiles, ballistic missiles, and hypersonic missiles. The Patriot battery shot down a total of 17 hostile targets but one of the interceptors might have malfunctioned in a launcher during this extremely stressful attack situation. This explains the "minimum damage" revelation which is FIXED by the way. This is incredible level of performance - something that was not predicted even in brochures.
Do tell me if (any) terrestrial Air Defense System can withstand this type of airborne assault. Best of luck.
If this was S-400 or even S-500 (systems that I do not underestimate), it would be toast.
