The Ukrainian military says its new weapon system, which launches antiaircraft missiles from a remote-controlled speedboat, has brought down two Russian jet fighters.

Ukraine’s shock drone strike on Russia’s strategic bomber fleet this week has generals and analysts taking a new look at threats to high-value United States aircraft at bases in the homeland and abroad – and the situation is worrisome.

A stunning attack in Russia highlights how small drones can be outfitted with new software and components to turn them into killing machines.

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

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.

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.

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.

French automaker Renault SA will produce drones in Ukraine, according to France Info. Renault will work with a small company to set up production lines dozens or hundreds of kilometers away from the frontline,
