Metal Shark 40 Defiant
6 U.S. Navy type patrol vessels have recently been supplied to Ukraine. These are already active in the Black Sea where they face a much more powerful adversary in the Russian Navy. But the Ukrainian Navy is building a reputation as an effective asymmetric force.
These are the same 44 foot patrol boats the Navy has been buying.

These are not combat boats. They are patrol boats designed for force protection, not for attack
Not unlike USN PBRs. Might be useful on the rivers.
