Cruise missile inspired by the Storm Shadow.
This is the ground launch version but you can easily convert it to air launch.
Open wings (AG1) before launch, they are only stowed so it takes up less space, more important for air launches. You can also fold them in a dive to gain a few more m/s.
Can go at like 320m/s at 7km, slightly faster at low level though.
Range is over 300km, haven’t fully tested that but it can go decently far.
