So you think you're smarter than the planners who came up with DMO (of which the LAW is a key component)?
These guys also came up with Littoral Combat Ship, the Zumwalt "destroyer" and the Gerald Ford CVN.
All are unmitigated disasters that are costing untold billions yet actually decreased USN combat capability and put back warship development and production by decades!
And they are most definitely a return to the WWII LST – similar dimensions and performance except these can't carry tanks (and the Marines are getting rid of them anyhow)!
But then the new DMO and Marine Corps model seems to be based on Japanese strategies for invading islands in 1941.
Land small next to useless groups of men on undefended little atolls, give them some light anti ship missiles (2020 equivalent of small coastal artillery) in the hope the enemy stays away.
And if the enemy does come, then affix bayonets and prepare to sell your lives dearly cause a handful of missiles won't stop the enemy.
If they're aiming for islands close to China then the Chinese already totally screw up US maths here with their 80+ Type 22 missile boats, 44 Type 056 corvettes (and building more with a plan of 71 ships), 34 coastal gunboats and a plethora of coast guard type patrol ships which would be used to deter coastal infiltrators as well as increasingly numbers of MPAs, drones etc.
That's not including the major surface combatants, which China is churning out much quicker than the US.
Of course I doubt the Chinese will be looking at landing troops on Guam or Tarawa or Guadalcanal.
Oh and all totally useless for operations against the Russians who the Navy seem to have forgotten about.

I note the transit speed of these has been quoted as a measly 14 knots which is average speed for a bulk carrier. So they're slow.
I guess those zippy Chinese fast attack craft will just have to look the other way, whilst the Marines get into position.
