The Donald Trump administration has cut off vital support for Ukraine’s F-16 jamming capabilities, leaving the Ukrainian Air Force at risk of losing a critical air countermeasure. However, Ukraine has the option to shift the burden of air jamming onto French Dassault Mirage 2000 fighters, which are equipped with powerful jammers and radar warning receivers. The French Ministry of Defense has promised to install new electronic countermeasures on the Mirage 2000s before handing them over to Ukraine, showing strong support for the country. In the long term, Ukraine may need to refit their F-16s with non-American electronic countermeasures, but this could be costly and time-consuming.
