The programs you mentioned were sole source awards and generally not nearly as expensive, hence less political.
As to the "more joint" solution to the CSAR fleet, it could mean as Buddha pointed out that the 160th would take over the RV portion; but that would mean many more aircraft and crews, and they already have problems with getting as many crews as they want, so still not a cheap option. It could also mean that the AF would get a "joint" HH-XX (just buy the MH-47, an HH version of an MH-60M/S, etc.) this would be an approach similar to the JSF.
Or I may be one of the last AF Helo pilots.
