Spanish frigates and Constellation's different mission requirements

How would buying 16-24 Álvaro de Bazán and eight Bonifaz-class frigates affect the US Navy, and would Spain order more Bonifaz ships?

No direct substitution is favoured because the designs serve different missions; additional Spanish orders are considered unlikely.

The proposed Spanish purchase receives a negative assessment because Álvaro de Bazán emphasises air defence while the intended American frigate mission places greater weight on ASW. The later F110 design receives a more favourable initial reaction as a starting point. A second panel member argues that it still cannot meet the full American mission, and the first agrees that adaptation would be necessary. The same distinction applies to Legend-class cutters, whose existing mission differs from the frigate requirement. Additional Spanish orders are judged unlikely.
