Learn and Adapt, or Perish: The Case of the F35 Lightning II

We assess to what extent a (co)evolutionary macro level approach enhances our understanding of learning in governance processes. We ask the question: in what ways do actors learn to improve their chances of long-term survival in complex governance processes? We deploy a model of collective decision making moulded upon fitness landscapes to analyze a longitudinal case study of collective (political and administrative) decision making, namely the process of developing and acquiring the F35 Lightning II fighter jet. The study demonstrates that actors learn how to ensure survival over time but create a failing megaproject in the process.

Powering Out of Trouble

This article presents a study of Pratt & Whitney’s J58, till date the best and high-powered engine for manufacturing lessons required for the development of F35 Joint Strike Fighter. The J58 Blackbird engine is a variable cycle engine, a turbojet/ramjet combined-cycle engine. It is a conventional afterburning turbojet for take-off and transonic flight, and it approximates a ramjet during high-speed supersonic cruise. The power plant for the Blackbirds is a marvelous development on the part of Pratt & Whitney, as it is the only engine of its kind in the world. The noise and vibration from a J58 test was so great that it could rattle the side-view mirror off nearby cars. The engine was developed at an isolated research center in Florida. At take-off and low-speed flight, the J58 engine/afterburner provides most of the thrust. Both of the Blackbird’s twin nacelles contain an engine supersonic inlet, the J58 engine with its afterburner, and an exhaust ejector nozzle. All three components contribute to the Blackbird’s propulsive thrust in varying proportions, depending on flight speed.
