Zelenskyy says Ukraine had to change faulty air-defense equipment from a European ally 'again and again' because it didn't work

• Ukrainian President Volodymyr Zelenskyy said a European ally provided a faulty air defense system.

• He said Ukraine had to "change it again and again." Zelenskyy did not say which country provided it.

• Zelenskyy also told the AP that Ukraine is still waiting for the US Patriot system to be deployed.

Ukrainian President Volodymyr Zelenskyy said a European ally provided Ukraine with a faulty air defense system, although he withheld which country was responsible.

Since Russia's invasion in February 2022, Ukraine has received billions of dollars worth of security assistance from Western nations. This includes anti-armor systems, artillery weapons and rounds, as well as air defense systems.

Some countries rushed to supply equipment, some of which dated back many years.

One air defense system provided by a European nation failed, resulting in Ukraine needing to "change it again and again," Zelenskyy told the Associated Press.

Zelenskyy also noted that some of the weapons promised to his war-torn country have yet to materialize.

European nations have contributed billions in military aid to Ukraine, with the United Kingdom, Poland, and Germany being the largest donors from the region.
