Around 90% of Russia's drones and missiles fired in May were destroyed, the Kyiv Post reported. The bulk of Russia's munitions expenses stemmed from destroyed Kh-101 and Kh-555 cruise missiles, costing $1.48 billion, the Kyiv Post reported. The Kyiv Post also wrote that Ukraine used 401 Shahed-136 drones costing around $20,000 each, and that 362 were destroyed by Ukrainian air defenses. That failure rate eclipses earlier estimates from the US, which said in 2022 that as much as 60% of Russia's missiles never reached their targets. US Defense Secretary Lloyd Austin said in November that American NASAMS air defense systems sent to Ukraine had a 100% success rate of intercepting Russian missiles.
