Worf used this weapon to shoot down a shuttle and stun an enemy attack group.
So, is there some reason why this weapon has not been researched as an addition to the Trek arsenal?
I'm assuming it's game mechanics more then anything, there is no current weapon along these lines.
Although, Champions Online has a rocket launcher skill with the requisite animations, so adapting that for STO can't be too hard.
And there is some crossover of the base code for animations between the two games.
An enterprising foundry author found a way to enable a couple of the CO animations by using a console, which would imply there is a "shared" animation base.
