The Romanian Navy notes with some consternation that the Bulgarians have decided to also put guns that shoot up on their ships. This compels a hasty redesign of the last 4 units planned for the destroyer program into ships with guns that also shoot up.
Nice design btw. Gunwise right between my vr30 and 31. A fight between these guys and the v30/31 could be interesting ( you have a 1.5 knot speed advantage, but vr30 has 2 more guns 5mm smaller, and vr 31 has 3 less guns 10mm bigger).
Now I think I am going to build a Romanian Conrad
