So playing around to convert real ships into BT equivalents . . .
Primary Armament
Long Tom Artillery- Battleship guns (12-16 inch)
Sniper Artillery- Cruiser guns (6-8 inch)
Thumper Artillery- Destroyer/Frigate guns (3-5 inch)
Arrow IV Artillery- ship to ship missiles
needs scaling/differentiation
Cruise missiles- surface to surface
Subcap missiles- surface to surface
Secondary armament
4+ inch guns- UAC/10, AC/10, ERLL, PPC/ERPPC or LRM15/20
3 inch guns or less- UAC/5, LL, LRM10
AA armament
LB-5X AC
Any torpedos
LRT racks
The only thing is, converting real warships will be slower than some canon- like the Jormungand that is 6/9 while most IRL would be 3/5 or 4/6. The other would be, for example the ship I saw, the BB35 Texas had ten 14 inch primary guns. It was also a older battleship, but gives it 10 Long Toms while something like the Jormungand only has 6 or 9, I cannot remember. But we also have destroyers like the Andryusha which has one or two Long Toms.
What would be some rules for conversions?
