Biden's decision to supply F-16s to Ukraine raises questions and boosts Kyiv's military capabilities.

The US will allow Western allies to supply American-made F-16 fighter jets to Ukraine and train Ukrainian pilots to use them. However, the details of how many jets will be supplied, how quickly, and what weapons they will come with are still unclear. The F-16s are a step up from Ukraine's Soviet-era fighter jets and have advanced capabilities such as longer-range radar and precision bombing. However, training and delivery will be a challenge for Ukraine, and they will need many aircraft and support assets to effectively use them.
