Com­pare Switch­blade 300 to the Sovi­et 82mm mortar:

Weight: Sim­i­lar, per missile.

Range: 3x greater

Accu­ra­cy: Sup­pos­ed­ly, they rarely miss. You could dive-bomb some­one in a fox­hole, as I under­stand it. While with a mor­tar, your chances of hit­ting some­one in a fox­hole are slim.

Cost: The cost of $6000 per mis­sile, means that even with, say, 50% accu­ra­cy, you could take out 100,000 tar­gets at the cost of just $1.2B. Unguid­ed mor­tar shells are cheap­er, but you need a lot more of them, plus the trans­porta­tion costs.

There was a lot of talk about the Switch­blade a while ago, but then they just dropped off the radar, like some news fad.
