Russia and Ukraine are producing ever larger numbers of innovative aerial weapons, hoping for a breakthrough as ground combat is largely frozen.

Ukraine's defenses have held the line on most fronts, but there's one glaring weakness -- Russian ballistic missiles. Ukraine is desperately short of U.S.-made Patriot air defense missiles needed to defend against the Russians.

The long-range munitions are an important part the military's arsenal, allowing accurate strikes from a safe distance. US-supplied ATACMS have played a key role in the war in Ukraine, allowing Ukrainian forces to attack targets inside Russia.
