I thought we were talking about the (lack of) need for a managed transition?!
I see no reason to expect a loss in capability. In fact, it will actually be enhanced by the new aircraft and facilities. The new bases will be stood up with the same standard as the bases very soon to be operating under GAPSAR. The contractor will be responsible for maintaining these standards. Surely that's enough? Or are the mil SAR aircrew suggesting that they, and only they, could be the future guardians of SAR standards?
