 The interval between waves of Russian missile strikes might be growing because Russia now needs to stockpile a critical mass of newly produced missiles directly from industry before it can resource a strike big enough to credibly overwhelm Ukrainian air defenses. UK Ministry of Defense announced it on Twitter. UK Defense Intelligence notes that on March 9, Russia conducted a wave of at least 80 long-range strikes against Ukrainian critical infrastructure. Russia deployed cruise missiles, air defense missiles in a surface-to-surface role, Iranian one-way attack uncrewed aerial vehicles, and an unusually large number of hypersonic air launched ballistic missiles during the attack. This was the first major wave of long-range strikes since February 16, 2023, and likely one of the largest since December 2022. Ukrainian officials reported at least 11 civilians killed. The interval between waves of strikes is probably growing because Russia now needs to stockpile a critical mass of newly produced missiles directly from industry before it can resource a strike big enough to credibly overwhelm Ukrainian air defenses.

Ukrainian President Volodymyr Zelensky and European Commission President Ursula Vonder Leyan condemned Russia's missile attacks on Ukraine on March 9 during a phone call.
