The Next Great Engine War Was Not What You Thought It Was

The author compares and contrasts the various "engine wars" starting with the F-15's engine competition, fifth-generation engine procurements (F-22 and F-35), and finally, adaptive cycle engine technology development. He emphasizes the value of competition and the need for clear requirements to drive technological investments, leading to recommendations including technology roadmaps to facilitate transition pathways and funding technology maturation programs to ensure healthy competition.
