In a clear night sky above the shores of Odesa, the faint glow from missiles streaks over the Black Sea.

For much of the war, it was one-way traffic, with Russia using the occupied Crimean Peninsula first as a launchpad for its full-scale invasion and then as a staging ground for routine aerial bombardments.

Ukraine, now armed with American-made precision missiles, is for the first time capable of reaching every corner of Crimea — and the missiles are increasingly flying in both directions.

It is a new strategic push as Kyiv seeks to raise the cost for Russian occupation forces that have long used the peninsula as a base of operations just off Ukraine’s southern coast.

While it is unlikely to have much effect on the front line, Ukraine’s campaign with the long-range version of the Army Tactical Missile Systems, known as ATACMS, appears meant to force the Kremlin to make difficult choices about where to deploy some of its most valuable air defenses to protect critical military infrastructure.

At the NATO summit in Washington this past week, President Volodymyr Zelensky of Ukraine said the Crimean campaign would have limited effect as long as Moscow can move its bombers to the safety of air bases deep in Russia. He pressed the Biden administration to lift restrictions so Kyiv can extend its strikes deep into Russia.
