"Ukraine's Air Force Gains Momentum as Russia's Aerial Power Wanes"

Ukraine claims to have shot down 15 Russian planes in two weeks, prompting a reduction in Russian aviation activity in eastern Ukraine, according to a US think tank. The decrease in flights follows a series of Ukrainian successes in countering Russian air dominance, including the use of tactics to target Russian combat jets. Russia's use of glide bombs, which require flying at higher altitudes, may be making its aircraft more vulnerable to Ukrainian defenses. Meanwhile, Ukraine is facing ammunition shortages as Republicans in Congress block $60 billion in aid, allowing Russia to intensify its attacks.
