Did some digging over the JA/AJ 37’s and noticed that they had a Central Navi-Computer, early models heralded a CK 37 system, and later a modification of the SKC-2037. This was in the Late 60’s, which was before the F-14, which makes me raise the question of was the F-14 really the first Micro-processing laden aircraft.
(The CK 37, known for being the first airborne digital computing system)
As for the second thing I noticed, and have noticed in game for a while, was a rear facing MAW (IR) system, while if warned the pilot of incoming IR missiles, however the pilot was required to manually deploy CM’s, this would be a great addition to all of the Viggen aircraft, and allow for better gameplay in hectic environments.
(The IR receiving block shown on the very rear of the aircraft in a dome shape, this is a Di model, but the JA37C is confirmed to carry it)
It also sports one of the first monopulse radar system on aircraft. This can send track and directional info with a single radar pulse, and have a much higher immunity to jammers. (These were tested, and had a 50/50 shot of tracking and F-4 phantom on the deck, with ECM systems)

It is also lacking a 50km BVR/ACM mode, which was present on the JA models, greatly improving its effectiveness and capability with the AIM-7E-2, which also had the ability to multi-slave the missile to two painted radar targets. Giving the ability to also track two targets while scanning and locking the AIM-7E-2’s. While all of this, it is also capable of using its terrain avoidance system, allowing extremely low flight and terrain mapping.
On another note, I opened a thread on the Viggen D weaponry, which I would like to restate, I’d like the addition of the RB-99’s, however, allow it to receive all of its systems, and put it at 13.0, and folder it under the current D, as the Di model.
