The challenge

Building a stronger, more innovative Defense Industrial Base

The defense industry is facing two compounding problems: a constricted supply chain and propulsion technology that hasn't meaningfully advanced in 50 years.

A fragile, shrinking supply chain

Solid rocket motor production depends on a vanishingly small industrial base, with long lead times that leave the United States exposed at exactly the moment demand is accelerating.

Aging propulsion technology

Solid rocket motors cannot throttle or restart in flight — once ignited, they burn on a fixed profile with no mid-course control. They detonate on impact, creating real risk for the troops who store, transport, and fire them. And no amount of new capacity changes the underlying architecture, which hasn't meaningfully evolved since the 1970s.

Why it matters now

The Department of Defense has placed $4.1B in replenishment orders since October 2024 alone — but every unit coming off an expanded production line still depends on a fragile supplier base and 1970s-era propulsion architecture. Capacity is being rebuilt. Capability and resilience are not — and defense primes face mounting pressure to deliver mission-critical systems faster, more affordably, and without dependency on a supply chain that isn't theirs to control.

How vaya solves it

A vortex-hybrid engine. Non-explosive fuel. Built entirely on American soil.

Vaya's vortex-hybrid engine throttles from 0–100%, has demonstrated restart capability in 11 tests, and uses a non-explosive HDPE fuel grains that burn instead of detonating. Itt's demonstrated a 35% range increase over current long-range missile systems, confirmed through active Army testing and validated by industry primes.

Every engine starts as recycled plastic in Cocoa, Florida, and ends as a tested propulsion system without ever leaving Vaya's hands. No single-source suppliers. No overseas dependencies. No waiting on someone else's schedule.

Performance

Capability the SRM base cannot deliver

Full-authority throttle, restart capability, 35% range increase, and non-explosive fuel — in a drop-in form factor for existing military systems.

Manufacturing

American workers. American supply chain.

3D-printed and metal additive manufactured fuel grains, in-house CNC machining, and on-site test infrastructure — every step performed by Vaya's own engineers and technicians at one Florida location.

Vaya went from clean-sheet design to a live 5 inch-class tactical engine test in five months. The traditional industrial base measures that timeline in years.

WHY DOMESTIC MANUFACTURING MATTERS

Manufacturing isn't just an
operational capability. It's a
strategic advantage.

Every Vaya engine is designed, manufactured, and tested in Florida by American engineers and technicians who answer to no foreign supplier and no overseas timeline. In an industry that has relied for too long on a global network of more than 200,000 suppliers, controlling production end-to-end is more than just a cost savings. It's vital to our national security.
