Fighter-class
None given, but would be "FT" for a basic fighter
Corvettes, whose actual designation would be "CT" but MCV, MLC, etc is more intuitive
[V-]MLC = as with
UberJumper
[V-]MCV = Missile Corvette
[V-]LCV = Laser Corvette
[H-]PCV = Pulsar
[H-]FCV = Gunship
while both energy-weapon Corvettes could be given a similar notation for "energy weaponry" some provision is given for gameplay reference.
Frigates - FF for a plain military frig.
[V-]FF = Assault Frigate, which is a general-purpose gunboat/ship
Is a dogfighter
[V-]FFG = Heavy Missile Frigate, "G" for guided weapons
[V-]FFB = Battle Frigate
[V-]FFP = "P" for patrol/policing vessel
[V-]FFH = Denotes Heavy Frigate class, which is specifically FFB and FFP above.
[V/H]FFM = Specialized "boarding assault" vessels, "M" for Marines, used for both Marine and Infiltrator ships
[H-]FFE = Escort Frigate - reconfigured for general-purpose gunship/gunfire support duty, "Flak Frigate" model
Is a dogfighter
[H-]FFT = Torpedo Frigate - but in actual case should use "G" designation as well, T is better for gameplay reference.
[H-]FFI = Ion cannon Frigate
[H-]DFF = Defense Field Frigate, did not use "FFD" as it would mean "Drone Frigate" in this mod.
[H-]FFS = Support Frigate, "S" for easy gameplay reference.
Otherwise inconsistent with "Strike vessel" below!
[H-]MTR = Monitor
Super/Capital class
[V/H]CV = Carriers
have variant designations after "CV" to separate them from Corvettes
[V-]CVS = Strike Carrier
[V-]CVSR = Strike Carrier, long-range reconnaissance loadout
[V-]DDG = Destroyer, whose primary weapons are guided missiles, hence "G" designation.
[V-]DDL = Destroyer flotilla leader
[V-]BCFG = VBC: "F" = denotes heavy [primary] gun or plasma weaponry as used in ST:SFC on large capitals,
but in RL would mean "fast" as in the case of PCFG, inconsistent, yes.
[H-]DD = Standard destroyer
[H-]DE = Destroyer Escort
[H-]BCI = "I" refers in this case to its main armament of ion cannons, as with FFI.
[H-]CVR = Scout carrier
[H-]CVED = Escort carrier, that deploys and controls drones.
This is just added here for a bit of a different POV regarding ship class designators for HW/2.
