Converting that extra finding into trained personnel is going to take a decade given the challenges of the recruiting system, throughput of the schools, shortage of instructors, etc. It's not an overnight problem that money can solve. Especially for tech trades which take 12-24 to reach OFP.
I just don't get the obsession with a specific airframe vs. capability. Airlift is undergoing a massive expansion as is, with the 330s, more than the doubling the output of the outgoing Polaris fleet. And probably getting even larger. Airlift has grown so much, they are starting to run out of room in Trenton. If we end up with more Hercs and C17s, they might have to move out the 330s, which would be entertaining after they spent/are spending a billion dollars to make Trenton ready for them.
