The US has ended its support for Ukrainian F-16s, specifically cutting off vital support for their jamming capabilities. However, Ukraine may be able to shift the burden of air jamming to French Dassault Mirage 2000 fighters, which are equipped with their own powerful jammers. The French Ministry of Defense has promised to install new electronic countermeasures on the Mirage 2000s before handing them over to Ukraine. This development may help Ukraine maintain its air defense capabilities despite the loss of US support.
