So have we seen, the war in Ukraine is providing a real-time testing ground for nations defending against drones.

But unidentified drones are also a concern here in the United States.

Liz Landers is here with more on a recent incident at a military base in Louisiana.

John, the week of March 9th, a swarm of drones repeatedly hovered around Barkstale Air Force Base in northwest Louisiana.

A spokesperson for the base tells PBS NewsHour that it was unauthorized and criminal activity

that's now being investigated by both federal and local law enforcement.

ABC News reported that the drone flights lasted four hours at a time, deliberately maneuvered within the airspace over the

base, and appeared to be jam-resistant. Marksdale is a key facility for the U.S. in the ongoing

fight with Iran, housing B-52 bombers and nuclear weapon storage facilities. For more on this,

we turn to retired Air Force Lieutenant General Dave Deptula.

He is now the dean of the Mitchell Institute for Aerospace Studies General.

Thank you for joining us this evening.

You bet, Liz. Good to be here.

We just saw in Simon's story how advanced Ukraine's counter drone technology is.

And yet, the U.S. is having trouble stopping all these drones that Iran is launching at its neighbors.

How is it that Iran is so advanced here and that the U.S. is not?

Well, what I would tell you is that with respect to Ukraine, who are the real experts, with respect to defense, is they're much better at defending against drone

attacks because for them, this is an existential fight.

Russia is trying to eliminate Ukraine as a sovereign country, erase its people, identity,

and culture.

So when a nation is facing that kind of threat every day,

it adapts with extraordinary speed and seriousness.
