Russia's surge in missile strikes in Ukraine is partly designed to exhaust Kyiv's supplies of air defenses and finally achieve dominance of the skies above the country, a senior Pentagon official said on Saturday.
Russia has been hammering cities across Ukraine with missile strikes over the past week, in one of the heaviest waves of missile attacks since Moscow began its invasion nearly nine months ago.
Ukraine says the strikes have crippled almost half of Ukraine's energy system, creating a potential humanitarian disaster as winter sets in.
Colin Kahl, the Pentagon's top policy advisor, cautioned that Moscow also hoped to deplete Ukrainian air defenses that have so far prevented the Russian military from establishing dominance of the skies above Ukraine.
"They're really trying to overwhelm and exhaust Ukrainian air defense systems," Kahl told reporters during a trip to the Middle East.
"We know what the Russian theory of victory is, and we're committed to making sure that's not going to work by making sure that the Ukrainians get what they need to keep their air defenses viable."

Russia fails to overpower Ukraine's air force and air defenses
Following Russia's invasion of Ukraine on Feb. 24, Western military experts widely expected the Russian military to try to immediately destroy Ukraine's air force and air defenses. That is a core element of modern military strategy, allowing better support for advancing ground forces.
Instead, Ukrainian troops with surface-to-air rockets and other air defenses were able to threaten Russian aircraft and the skies above Ukraine remain contested to this day.
That critical, early failure has been a core element of Russia's troubles in Ukraine as it presses its failing invasion, at tremendous cost in lives and military equipment.
"I think one of the things that probably surprised the Russians the most is how resilient Ukraine's air defenses have been since the beginning of this conflict," Kahl said.
"In large part, that's because of the ingenuity and cleverness of the Ukrainians themselves in keeping their air defense systems viable. But it's also because the United States and other allies and partners have provided a tremendous amount of support," he said.
US focuses on air defense supplies for Ukraine
Last week, US Defense Secretary Lloyd Austin focused on air defense supplies for Ukraine at a virtual meeting he hosted from the Pentagon. Ukraine's allies have been providing everything from legacy Soviet-era systems to more modern, Western ones.
For the United States, this includes newly US-provided NASAMS air defense systems that the Pentagon says so far have had a 100% success rate in Ukraine intercepting Russian missiles.
"We've been transitioning the Ukrainians towards the NATO standard equipment across the board, but not the least of which includes air defense systems like the NASAM," Kahl said.
The United States has provided more than 1,400 Stinger anti-aircraft systems along with counter-artillery and air surveillance radars to Ukraine.
