"A gust of wind, a black sky, a crater where the mountain once stood."
Did someone say... artillery? As suggested by MechWARRIOR57.
At a glance, the PROJECT: Heavy Vortex may merely appear to be a scaled-up vortex cannon. However, it is much more destructive. It fires three scaled up vortex rounds simultaneously.
Like the original vortex cannon, the explosions created oscillate. Compared to most artillery, PROJECT: Heavy Vortex is also quite light, which makes it ideal for flying warships. It is also mirror-friendly, which makes installation easy.
Press 1 to fire. Use VTOL and trim to aim.
