Makes some sense. Hypersonic missiles change the strategy. Need ships for sure but need other stuff too. I am sure Hegseth and team are all over it.
With the advent of relatively cheap loitering precision weapons and hypersonics, Mass as a principle of war, has regained prominence over maneuver at least until defensive measures catch up.
A couple really really expensive but very capable things can be overwhelmed by a large number of inexpensive things. The other factor is that if you only have a few of something eve if very very capable you will be very very hesitant to risk that thing, therefore it will never produce the full value that you expect on the battlefield. We have told ourselves that the "mass" of our precision fires will counter "mass" produced by lots of people or inferior equipment. Well, the bad guys now have precision fires too and in quantity because "good enough" is cheap(er) and easier to produce now.
The other thing that impacts is the likely approach that your enemy has to warfare. Western way of war has long focused on maneuver...seizing key terrain, centers of commerce and transportation or governance. However what you see in Ukraine is Russia has shifted from their initial maneuver based approach and has instead, shifted focus on waging grinding war of attrition. Terrain and maneuver is less important, the focus is on the enemy force and forcing it to engage and suffer losses. They decisive factor in this type of warfare is the ability to generate new forces / weapons and employ them well enough to continue to bleed your enemy until it can no longer sustain the fight.
US experience in the Civil War and to a lesser extent WWI has really made attritional warfare something that is not discussed, or planned for. It is just not the way we want to fight, and not what the American people expect of their military officers. Each individual life matters. But what of China?
A confllict with China will be initially very bloody. Once bloodied it's illogical to expect that a first-rate power such as the US or China for that matter would simply give up. Nope. A very likely outcome is that it would turn into a war of attrition. Are we prepared for that? Doctrinally? What about weapons stockpiles? Ships? Ability to draft mobilize and train manpower? Our industrial base?
