This embed is designed to nudge SD towards a better fighter jet solution. Is it perfect? Far from it. I've yet to get something that is spot on and at best it produces something "fighter jet-esque" but it does seem to work better than just putting in "fighter jet" alone.

As with most things, your model and seed will really impact this. The images here were created using Deliberate 1.1 in Automatic1111, save for the last image, which was done in A1111 and Invoke with a lot of inpainting.

As always, your mileage may vary. Posting here in case it helps someone.
