Rocket Lab develops and launches GALS electric propulsion thruster with 200-unit production line operational, targeting to break industry bottleneck in EP supply
Peter Beck· Rocket Lab· Space· 2026-05-15· about Rocket Lab (RKLB)
“We unveiled our new electric propulsion thruster for satellites called GALS at Space Imposem last month, with a 200 unit production line already established and units delivered to ourselves for some of our own constellation programs. We've been inundated with inquiries from programs in need of hundreds of units each and we're ready to break the bottleneck on electric propulsion.”
Why it matters
Rocket Lab identifies and addresses a critical supply constraint in the satellite industry. Electric propulsion has been a persistent bottleneck limiting constellation deployment cadence.
Investment implication
GALS production addresses a market need estimated at hundreds of units annually. Competitors and customers (constellation operators, satellite manufacturers) face reduced pricing power if Rocket Lab captures significant market share. Traditional EP suppliers (e.g., Busek, Aerojet Rocketdyne legacy products) may face margin pressure.
