Technology Maturation and Risk Reduction
What it actually means
The acquisition phase between Milestones A and B dedicated to maturing critical technologies, reducing integration risk, and firming requirements before committing to full development — prototypes and competitive demonstrations live here. Its exit test is honest: are the technologies really mature, or does the program just need Milestone B?
Where you'll meet it
The A-to-B phase of the major capability pathway.
