An SAI-modernized C-130 in flight
SAI Legacy Since 1987 · Independent Aerospace Engineering

Proven engineering
for the world's workhorse.

Snow Aviation International modernizes, re-engines, and re-certifies the C-130 and other heavy aircraft — nose to tail, under one roof. Prime-contractor capability, without the prime-contractor timeline or price.

The Challenge

Built to compete
with the primes.

Fleets don't need a clean-sheet aircraft and a twenty-year acquisition cycle. They need more range, more payload, modern avionics, and decades of additional service life — delivered now.

SAI was founded on a simple proposition: assemble the engineering, prototyping, and certification capability of a major prime into one focused, fast-moving house — and apply it to the platforms operators already trust. The result is prime-level work, fielded faster and at a fraction of the cost.
