Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.

An analysis by multiple experts of new video and satellite images suggests that at least 11 Russian bomber aircraft and one large transport plane were badly damaged or destroyed in Ukraine's drone attack on Sunday.

Russian ballistic missiles have been launched toward Ukraine from multiple directions, the Ukrainian Air Force said on Telegram Friday.

Ukraine says that a large Russian drone-and-missile attack has targeted the eastern city of Kharkiv, killing at least three people and injuring 21.

Drones are “ubiquitous, because they are quite useful, and they're demonstrating that every day in Ukraine,” one analyst told NBC News.

The Pentagon notified Congress last week that it will be diverting critical anti-drone technology that had been allocated for Ukraine to US Air Force units in the Middle East, according to correspondence obtained by CNN and people familiar with the matter.

Both sides are now using large numbers of attack drones controlled via fiber optic cables which are immune to radio jamming making them effectiveley unstoppable.

Ukraine unleashed more than a hundred drones smuggled deep into Russia in what it called its most damaging attack yet.

Former Rep. Chris Stewart, a former fighter pilot, says the U.S. isn’t prepared for this change in modern warfare.
