Those are cool. The wing modifications they had to make to get it to work at high altitudes were significant.

A bog standard F-15 of any type. Pretty easy when you've got power to spare.

And how

Just look at this thing. It's specifically designed to mock the entire field of aerodynamics. Just MOAR POWER your way through any problems.

power to weight ratio is a bit messed up

For the arrow
> nine instrumented free-flight models were mounted on solid fuel Nike rocket boosters and launched from Point Petre over Lake Ontario while two additional models were launched from the NASA facility at Wallops Island, Virginia, over the Atlantic Ocean. These models were for aerodynamic drag and stability testing, flown to a maximum speed of Mach 1.7+ before intentionally crashing into the water.[35][36]
>Experiments showed the need for only a small number of design changes, mainly involving the wing profile and positioning. To improve high-alpha performance, the leading edge of the wing was drooped, especially on outer sections, a dog-tooth was introduced at about half-span to control spanwise flow,[37]
Then googling dog-tooth wing leads us here
https://en.m.wikipedia.org/wiki/Leading-edge_extension
>A dogtooth is a small, sharp zig-zag break in the leading edge of a wing. It is usually used on a swept wing, to generate a vortex flow field to prevent separated flow from progressing outboard at high angle of attack.[1] The effect is the same as a wing fence.[2] It can also be used on straight wings in a drooped leading edge arrangement.
