Could Germany have solved its frigate needs by building more F125s?
Short answerIt could have built more, but should not multiply a design optimized for peace and still missing the expensive defensive capability.
NotesF125 is effective only under assumptions that it will not face a major war. Its RAM launchers provide close-in defence but do not replace the more expensive wider air-defence layer. Building more of the same class would therefore add presence hulls without creating a balanced escort for contested operations. The answer separates fleet quantity from whether each unit carries the capabilities its likely conflicts require.
