That DH bonus is about to be insane. That's if PERS-41 will admit there's a problem, which they've always been reluctant to do. I was one of the last YGs to do the baby SWOS, 30 month tour w/ ASAT, then 18 month tour pipeline. That 30 month tour was rough on people. Luckily, my XO was a saint and worked to get me off the ship 6 months early. I can't imagine that this new move to promise near-endless sea time is going to be good for retention.
I really think we need to adopt a career path similar to the way the Royal Navy and many of our partner nations do theirs. You qualify as a jack-of-all-trades during your first tour and then choose operations/combat systems or engineering for the rest of your career. That way you get folks who are extremely proficient ship drivers and warfighters and folks who can run the plant and manage maintenance with their eyes closed. It takes two different mindsets and not everybody can do everything.
It's even more of a split than that.
The RN (and everybody else using their model) splits it into Ops, Combat Systems, and Engineering.
The Ops guys focus on ship driving and warfighting/tactics.
They have Weapons Engineering and Marine Engineering Officers to oversee C/S and Engineering.
Their enlisted sailors are also more firmly split between technicians/maintainers and operators/watchstanders.
