Funny enough, when the Iowas were recommissioned in the 80s one of the rationales was they provided four more O6 SWO sea command billets.
The USN now has more O7s and above than they have ships.
Just sayin’
However there’s no way that the Zumwalts are “destroyers”. They are only called that because they were intended to replace the VLS\Land Attack Spruances with an Aegis-equipped variant that would have the CG designation and replace the Ticos.
IOW it was all PR and spin nonsense to help get and keep the program funded. Just like the F-35 light attack jet being called a “fighter”
“The USN now has more O7s and above than they have ships.”
That is pretty sad isn’t it. The bloat of bureaucracy everywhere, with more chiefs than indians in every part of life. Private sector included.
