Description

In this episode, Mike sits down with Dan Jablonsky, CEO ofUrsa Major, to discuss solid rocket motors and how Ursa Major is doing it differently.

Once dominated by just two suppliers, America’s SRM propulsion base has been stretched thin—leaving gaps exposed by today’s conflicts.

Dan explains how Ursa Major is tackling that challenge withmodular production, 3D printing, Highly Loaded Grain propellants, and advanced manufacturing using what they’ve learned from their liquid motor product lines.

We also talk about the big picture: hypersonics, cruisemissiles, and upcoming programs with RTX (Raytheon), the U.S. Navy (SM-2, SM-3, SM-6), the Army, and Stratolaunch.

If you want to understand why missile production is one of the biggest defense challenges of our time—and how new entrants like Ursa Major are building solutions—this episode is for you.
