Finished the book.
Lots of interesting tidbits in the book.
They abandoned the "tooth" design after flying the prototype. During testing they had to scale the radar wavelengths to the scale models. The exhaust had a significant radar signature so Lovick came up with the idea of ionizing the exhaust by way of a cesium fuel additive. I was pleased that the story carried on through the development of the F117 Steal Fighter, recon satellites and the Navy's Sea Shadow. Unfortunately it stopped there. There was no discussion of how they moved from facets to the curved surfaces of the B-2 and Raptor.
