Woodward makes the control systems that meter fuel, motion and combustion inside the world's engines. It rarely builds the engine or the aircraft — it supplies the fuel systems, valves and actuators that go inside them for GE, RTX, Boeing, Caterpillar and Rolls-Royce, then earns high-margin aftermarket revenue for decades. Roughly two-thirds of its ~$3.6B in sales is aerospace; the rest is industrial (power generation, transportation and oil & gas).

In simple terms

Woodward doesn't build the jet or the power plant — it builds the precise parts that meter fuel and move surfaces inside them. Metals and electronics flow in; Woodward turns them into fuel systems and actuators for GE, RTX, Boeing and Caterpillar; those go into engines and turbines that ultimately serve airlines, militaries and utilities.
