So German rockets in the Second World War.

And that's what war does.

You just have to speed up that process, correct?

Dennis says their weapons, which also include long-range drones, are already hurting Russia.

So it's making a difference what you're doing with the weapons here in the battle.

But can it win the war?

There's no game changer.

The only game changer we have is our will.

If we have the will to win, we'll have to tire a day later than Russia.

Before the war, Irina was an architecture student.

Now she's trying to dismantle the Russian war machine.

So your security guarantee is you producing your own weapons?

And do you think that can make a difference in this war?

Another factory at another secret location is churning out less complex long-range drones.

They've been behind 60% of Ukraine's deep strikes.

They're producing 200 a day.

And Irina says they're deliberately trying to avoid foreign components.

You don't use American companies.

Why?

Ukraine's long-range drone strikes, though, are having some success.
