t43562,
I'm afraid you don't get something for nothing.
There are indeed less personnel directly related to the launch and recovery of a B vice a C but you need more in other areas if we revert to B.
In order to produce the same effect as a C with a B, you will either need more aircraft (= more maintainers) or fly the same aircraft more often (= more maintainers).
And the training burden reduction inherent in C operations when compared with legacy (even the USN is looking at reducing the training burden with a C) will offer relative savings.
