No you wouldn't replace them right now. You would replace them later timed with their phasing out in the absence of a SLEP. A short term increase in production would allow you to accelerate your recapitalization of the rest of the fleet freeing up out year deliveries to switch ANG squadrons that currently fly the F-15.

Old radar types never die; they just phased array
