The modified FREMM considered for Portugal is judged a reasonable variation on the Italian design. FREMM construction also provides an established production background. The American Constellation programme is used as an example of extensive modification. In this assessment, those changes took the American ship so far from the original FREMM that little of the relationship remained.

FREMM variants and the extent of Constellation's redesign
The Portuguese FREMM variation receives a favourable assessment, while Constellation illustrates how extensive changes can weaken a design's connection to its parent.
