For example, the F-22, PAC-3, and ATIRCMS/CMWS programs had less than one-third of their engineering drawings completed at their critical design review, but each obtained the funding necessary to move onto the initial manufacturing of production representative prototypes.
The completion of engineering drawings is not essential to obtaining funding.
