We used to go down to the irrigation ditch when we were kids and watch the Water Skippers.
I have since learned that they could ride atop the water because of something called Surface Tension.
They were quite fast.

And can be had for the low low price of trillion dollar earmark. Looks like the JSF for the water.

Not even close.

The vessel is also capable of operating in wave heights of up to 2.4 m (8 foot). Tops out at sea state 4?

This design might work at sea, but would fail in “brown water” (near the coast or in rivers), because of submerged obstacles, e.g. water logged timber. One good hit by a water logged tree branch could ruin one of the “propulsion units” and cripple the boat. This happened to one of the Navy’s hydrofoil boats in the 1970s and completely totaled it.

It looks like the boats would be better suited for Coast Guard patrolling.

Those were ground effect craft. This is a different critter.

They’ll need years of development before the USN considers them. The structure is extremely complex, with multiple stress risers subject to cracks etc. Engineering components in the struts and the pods will be extremely difficult to access, so maintenance will be a nightmare. If they are sent to distant areas like the Persian Gulf, they will soon fall out of service, one at a time, requiring total refits back in the USA. Compared to these, the Pegasus hydrofoils were simple and bulletproof, and the Navy dropped them after about 15 years.
