Years ago a weapons system was experimented: a gas-
powered launch platform. This was scrapped because it
was not deemed precise enough, as it was difficult to get
the mix of gasses correct, thus messing with trajectories.
The other technology is in current development:
electromagnetic launching.
It is well within experimental
stages, as huge rooms are used to store the energy used,
among other impracticalities.
Why not combine the two technologies? Our sensor
technology is precise enough to detect slight variations in
velocity even at high speeds.
Sensors within the platform will allow for the detection of
velocity variances, and using this information,
electromagnetic forces can be used to either speed up, or
slow down the projectile, correcting the total force
applied.
Refining a system like this could provide more flexible
delivery platforms, being able to use different
gasses/mixtures, and using a widely varying range of
explosive forces (small forces for very short distances,
instead of facing your trajectory almost straight up,
subjecting your projectiles to wind forces).
