Question of the Day?
Good morning everyone, it's true, it's a very easy question, but I've noticed something.
I don't know if you're aware of it as well.
Within NATO, many navies (or rather, I'd say all of them) made no distinction between corvettes and frigates.
In fact, they were all designated with the letter F.
I remember the Italian Minerva class of corvettes (from F 551 to F 558, displacing 1,875 tons and 87 meters in length), contemporary with the Maestrale class of frigates (from F 570 to F 577, displacing 3,040 tons and 122 meters in length).
Both the Minerva class of corvettes and the Maestrale class of frigates are designated with the NATO designation F (i.e., frigate).
The Italian Navy no longer has corvettes but patrol vessels, designated by the letter P. Interestingly, the Thaon di Revel-class patrol vessels, 143 meters long and displacing 6,270 tons at full load (classified PPA), have a length of 143 meters.
In fact, I've noticed that since the 2000s, frigate tonnage has increased in all navies.
