Modern frigates judged against national doctrine

Which current frigates best fit the doctrine and roles required by their navies?

The Type 23 is a leading example, with Horizon, FREMM, Mogami, and Singapore's Formidable class also performing their assigned roles well.

The Type 23 receives special credit for evolving far beyond its original light ASW concept, a success the panel attributes partly to capable crews. Horizon, FREMM, and Mogami-class ships are also identified as strong matches for the roles their navies actually require. Singapore's Formidable class combines a flexible OTO Melara 76 mm gun with a compact frigate design built largely in Singapore. Its principal criticism is the split between short Sylver A43 cells limited to Aster 15 and longer A50 cells that can also take Aster 30. Standardizing all thirty-two cells at the longer length would have improved magazine flexibility for a modest additional cost and weight.
