Forb, I helped out with your post. To say 3/4 (and I know you meant 3 or 4) could easily be read as three-fourths.50 Frigates yes but 3 or 4 are not combatants but used for training, test ofc disarmed, namely:
Two 053H, one 053H1Q and very possible the last 053H2G
This means 46 or 47 combatants Frigates in fact.
Why isn't the PN expressing more interest in the 054A type? Seems like it would make a very strong addition to their surface fleet, providing much needed medium range air defence to any PN fleet.
