Answer

Patriot systems

Russian strikes on Kyiv increasingly combine ballistic missiles, which travel at speeds that only the most advanced systems such as Patriot can reliably intercept, with large numbers of slower attack drones intended partly to saturate and exhaust air defence resources before the more dangerous missiles arrive. Ukrainian officials have described this combined approach as deliberately designed to force a choice between depleting scarce, expensive interceptors on drones or leaving faster ballistic threats more likely to get through. Reports from the latest strikes suggest that dynamic playing out again, with residential buildings among the sites hit.

• Patriot interceptor production remains limited by a small number of specialised manufacturing facilities in the United States, with output constrained by component supply chains as much as by assembly capacity.
• Allied governments have pledged additional systems and interceptors over the past year, but delivery timelines routinely run into many months given global demand from multiple countries.
• Ukraine has invested in domestic drone-interception systems as a lower-cost complement to Western air defence, though these are less effective against fast ballistic threats.
• European stockpiles of comparable systems are themselves limited, reducing how much can be redirected to Ukraine without depleting other countries’ own defence reserves.
