Some machines are meant to compliment each other. Maybe they don't work directly alongside one another, but they were built with the other in mind.
Two (four?) great examples would be the F-15/F-16 and the Su-27/MiG-29. One is a long-range heavy fighter, while the other is a shorter range, cheaper fighter.
These pairs need not necessarily be military (or even aircraft). An airliner manufacturer building both a long-range and cheaper short-range aircraft design to fill in for the other would also be this.
This is all assuming that the two machines are of roughly similar generation.
To lead into the question, do you have anything of this sort?
From Graingy there's the GLF-80 "Imp", a highly maneuverable and lightweight dogfighter (arguably too maneuverable, actually), and the GHF-79 "Archfiend", a large and extremely powerful heavy fighter with enormous engines and huge missiles... which is also rather expensive.
GHF-79A "Archfiend (Note: Unreleased on SimplePlanes.com due to technical issues)
These weren't our only jet fighters from this time period, but they were designed in conjunction.
So, how about you? Do you have paired products?
@DeeganishCountryball My bad, I thought the aircraft were different airframes. Didn't realize they were derived from the same base.
@Graingy In terms of Model Names, we just take CLF-16, if its the first version, its the CLF-16A, if its the third, CLF-16C, If its the fifth, CLF-16E, you get the drill
as for the nickname: We just take the main role and put it behind the word "Faucon" (Unless its the A Variant)
@DeeganishCountryball I see. How does the nomenclature work?
@Graingy
A Model
B Model
@DeeganishCountryball Care to link?
In my Raxrian Aircraft, there is the CLF-16A, and CLF-16B
The A Model is a Cheap Lightweight Fighter
The B Model is a Expensive Heavy Attacker
