I think more about a "container ship" version about the size of the carrier Enterprise or larger. Direct from China to any major city. Probably with 100-1000 individual LENR reactors and gas cells. Massive redundancy. Much faster and probably much cheaper (and safer) than any cargo ship.
The dockworkers and port cities will hate it.
But your vision is also correct. It doesn't have to be rocketry or jet speeds to be useful aeronautically.
While no one was looking we actually ran out of places to build ports for ocean going ships.
One solution was to run container trains day and night from Mexican ports to Indianapolis, and also convert the East Side airport (a major field) into a place for disgorging passengers on European super size airplanes. That would give Indy the position NYC has had for the last 4 centuries!
If you followed the I35 discussions on FR you probably thought they were going to run the lines to Kansas City ~ but since this system would replace current EAST COAST sites Indy would be needed to do the job. KCMO and KANKAN are simply too far West!
LENR solves a problem ~ we would no longer need as many ships.
