I have 4 submissions for the challenge.
First, KAAB Anka. It's a normal air superiority fighter with a delta wing and a healthy amount of air-to-air missiles.

Second, KAAB Fishbed. It might or might not have been inspired by MiG 21 from Human Space Program. The trick is it's VTOL. Start the main engine with 1 and the VTOL engines with 2. It kinda lacks wing area so it's not as good as Anka in normal air combat, but it can also serve as a helicopter (it has air-to-ground armament).

Now to more effective but less orthodox designs.
KAAB Laser. From the name you can tell what's going on, and yes, it has lasers. To accommodate for two lasers that cover both hemispheres it was given two engines. It's not as maneuverable as Anka, but it kind of doesn't need to be - it has a 5km death sphere that no aircraft survives for long in. It doesn't have Sidewinders because lasers cover plenty of distance, and thus it can carry some air-to-ground armament too.

And finally, KAAB Hummingbird. If you look at it, it looks strange - it has weird wings, weird rudders, weird everything, it almost looks like a boat. It was all on purpose though. It you look at the RCS calculator you will see an average cross-section of 3m^2 - it means that the normal air-to-air radome only detects it at about 2700m, which is already basically gun range. It doesn't have many AMRAAMS and instead opts for Sidewinders for close air combat. Don't forget to extend landing gear when taking off!
