The Arrow would be a terrible, terrible aircraft for today's world.

It was built to shoot down Soviet bombers coming over the North Pole. It could not perform air superiority missions because it was too big to be agile. It could maybe be a strike fighter, but generally its reputation overstates just how good it would have actually been.

Something new please. We should be looking forward not pining for what could have been.

The future of air superiority, particularly with respect to sovereign defence is passive or quantum radar, autonomous A2/AD and directed energy.
