Wrong Term ...

 ... "shelved" is not the applicable term. More like removed into the deep recesses of archives of naval curiosities, never to be shown to public again in order to avoid embarrassment. I always stress--it is sometimes even painful for me seeing mighty US Navy, with its glorious heroic history, becoming a butt of jokes around the world, and not only because of the obsolete carrier-centric concept, but this:

The US Navy’s Trump-class battleship will be 'quietly shelved'. Summary and Key Points: The proposed Trump-class “guided-missile battleship” (BBG(X)) is pitched as a revival of American sea power, but the concept clashes with how modern naval war is actually fought. The platform is missile-centric—more like a bloated destroyer than a true battleship—while remaining highly vulnerable to submarines, long-range missiles, and ISR-driven targeting. Exotic add-ons like railguns and shipborne lasers are power-hungry and still unreliable at sea, while bigger hulls simply create bigger, pricier targets. Worse, U.S. shipyards are already strained, meaning BBG(X) would likely crowd out submarines and logistics ships that matter more in a China fight.

Child-emperor loves expensive shiny toys and he doesn't care, nor can grasp modern warfare, naval or not.

This is the thing which many US generals (and Admirals) still cannot grasp--the opposite side has as good ISR as the US. ISR means targeting and firing solutions, after that--all bets are off. Salvo Model rules and real serious militaries plan and fight based on model, some of them being in the process of constant update and modifications, 24/7 literally. This is how Russian General Staff operates, its GOU--Main Operational Directorate. Same goes for Main Staff of the Russian Navy. And the author correctly states, when it comes to China and her PLAN--the US Navy has only one avenue to pursue--submarine forces which still (emphasis on "still") maintains a sizeable, generational, lead over PLAN's submarine force. In terms of surface fleet--US Navy's readiness is a huge question mark. But in the end, it is not just arithmetic of MK41 VLS, it is what is in those VLS which makes all the difference.
