Ukraine needs drones not jets, Russia flying 20 times more sorties: US defense official
The Russians are flying an average of 200 sorties, military units, per day, while the Ukrainians are only flying about 10, a senior U.S. defense official told reporters Friday.
The official said much of the airspace above Ukraine is heavily guarded by both Ukrainian and Russian surface-to-air missiles, making air operations risky for both sides, but Russian aircrafts do not have to enter that airspace to do damage.
"You can launch cruise missiles from aircraft from a great distance away. And if your target is relatively close, you don't need to enter the airspace," the official said.
The Ukrainians have 56 functioning fighter jets available to them now and they are only flying them five to 10 hours a day, according to the official.
Noting Russia's vast umbrella of anti-aircraft capability over Ukraine and its larger air force, the official repeated some of the arguments we heard from the Pentagon earlier this week about the relative ineffectiveness of sending more aircraft to Ukraine.
"It makes little sense to us that additional fixed-wing aircraft is going to have somehow solve all these problems," the official said.
The official added, "What they need are surface-to-air missile systems, they need [man-portable air-defense systems], they need anti-armor, they need small arms and ammunition and they need these drones, because that's what they're using with great effect. And so that's what we're focused on."
Ukrainian forces are using drones to "terrific effect," especially against Russian ground movements, according to the official.
"They're trained on how to use them [and] they can fly below radar coverage by the Russians," the official said.
Russian troops have not moved any closer to Kyiv from the northwest since yesterday, still approximately 9 miles from city center. But, the U.S. has seen rear elements move up closer to those advance troops. Russians advancing on the capital from northeast are now 12 to 19 miles out, according to the official.
Mariupol is under increasing pressure on Friday as it is surrounded from the northeast and southwest, and is under heavy bombardment, the official said. But, Ukrainians are fighting back there.

Russians are "closing in on" Kharkiv, but the city is well defended and hasn't been taken yet, according to the official.
The Russians have now launched nearly 810 missiles against Ukraine -- almost half have been fired from within Ukraine using mobile platforms. The rest have been fired from Russia, Belarus, and a small number from the Black Sea, according to the official.
