"study would look at the feasibility of adopting or co-producing advanced hulls such as Japan's Mogami-class and South Korea's Daegu-class frigates" [Mogami-class]
The explicit consideration of adopting allied hull designs directly evidences the structural shift from domestic-only to allied co-production as a response to US shipbuilding incapacity.
Reasoning from this article
The article frames the US outsourcing study not as a one-off procurement decision but as a response to systemic domestic industrial failure—labor shortages, budget constraints, and repeated program cancellations. This generalizes beyond the US-Japan-Korea case: any advanced naval power whose domestic shipbuilding industrial base atrophies relative to a peer competitor faces the same structural dilemma of either accepting fleet shortfalls or ceding design sovereignty to allies. The cancellation of the Constellation-class frigate program is treated as symptomatic, not exceptional, reinforcing the structural reading.
