NF-14D doesn’t have to be the best version, least not long term. F-14D with the software upgrade that was planned put in to the tech tree, where it belongs right next to the F-15C GE, could have the top of the line of missiles, with the NF-14D having one stage down.
So - for arguments sake, and the lack of 9X on aerial platforms, let’s say this premium, renamed NF-41D, sticks with AIM-9L’s, AIM-7M’s, but get’s access to the AIM-120B as an option besides the AIM-54’s, leaving an option for 14A-65 to run the the 120A’s which would be the most accurate to it, and then in the tech tree, you have the F-14D with the software upgrade that they shifted the funding for as the true ‘last stage’ of the Tomcat’s development around 2006 running 9M’s, 7P’s, and 120C-5’s (since that’s the most advanced C model in game, unless they want to give it the C7). Which also leaves the proper F-14D available for the tech tree with the improved AIM-54C, and the Rebuild D’s can become a squadron vehicle or the like (alongside possibly 14A-65, but something like that feels like an event vehicle like the XF5U).
Not knowing if the 14D(R)'s had any model differences that they can’t be copy pasted from either the D or A model, at that point - you’ve got the money put in to developing the F-14D model for the game and all, NF-14D with AMRAAM’s is likely going to sell more than base 14D just because of performance, let alone if people rebel and actually boycott it, and you can literally copy and paste that model for the software upgrade and toss the new missiles on, which if it doesn’t further encourage the sales might generate some income on people throwing GE at it to get to the better missiles and all faster, similar story with the F-14D, but also having the F-14D(R) as the squadron vehicle with whichever version of AIM-54 they want could generate further sales in people buying GE to get it now instead of at best like 2-3 months from now. While still leaving open further copy/paste in the original F-14A+ as a possible lower BR premium (granted it might be slightly better than the tech tree A cause of the engines) and the 14A-65 as an event vehicle most likely, if not a squadron vehicle, which as a premium and event vehicle respectively allows them to generate even more money with lower production cost off both vehicles for a higher profit margin.
AMRAAM tomcat will sell a lot more, they can then more cheaply throw the real F-14D and the software patch one in to the tech tree at significantly lower costs, and generate a squadron vehicle - of which those last 3 will generate some income though not as much as the NF-14D, but all of which will likely help encourage the purchase of the NF-14D. They get the money they want, we get the Tomcat’s we want with the capabilities they had/we want based on what could and should have been, everyone wins.
