In the right-half of the sector at the top, you should find a terminal that unlocks a door. Behind this door are two rooms, one of which has weapons and supplies, the other having boxes blocking the climb.

Create the Velocithor V2-10. Climb up and blast a few boxes behind a wall that will prevent you from making your jump.

Now, climb up.

The supercharge is behind a glass window in the bottom-right section of the map. Hit the glass with a splintergun to break it.

Alternatively, use a nuke.
