Earlier this month, I broke the news that Andral Industries is raising more money at double its previous valuation.

But it isn't the only defense tech start of garnering surging investor interest.

Autonomous shipbuilder Seronik is raising $600 million in a series C that quadruples its valuation in less than a year to $4 billion.

Serenic already makes three types of unmanned surface vessels and has worked with the U.S.

Navy since it was founded.

The new capital will mean it can make larger ships and build a futuristic shipyard called Port Alpha.

CEO and co-founder Dino Mavrucus says the plan is to bring shipbuilding back in a way the

U.S. hasn't seen since World War II.

Everything we do at CERONIC is built around speed.

I mentioned we brought three products to market in under two years.

We've raised $850 million in just about two years.

That's more private capital than any company has raised

that's focused on maritime innovation in the last 50 plus years. Everything we do is centered on

speed because we understand the urgency of the problem set. When we look at what has equated

to naval power in the past, it's really shipbuilding.

The Chinese have invested so heavily in their shipbuilding capacity over the last 30 years

that they can outbuild the U.S. in terms of shipbuilding capacity, nearly 250 to 1.

That's a very scary stat. That is a very scary stat.

They went from 5% of global shipbuilding capacity to nearly 50% over the last 25 years.

We don't have time to wait.

We're doing this now.

Military shipbuilding is hard.
