Depends.

They’re gps guided 155mm artillery rounds. The electronics and guidance in them reliably survive the 50,000 g-force hell of being shot out of a cannon and then land (when used correctly) within a meter or 2 of their intended target over the course of a 20+km distance.

God knows how much was invested over the years to develop the system, and even once that’s recovered there is still an impressive amount of high precision manufacturing required to make a single one.

I’m positive they’re probably making $30k+ per round, but if it does its job is it worth it?

Genuinely confused by your first statement (in particular effective altruism). What does that have to do with the board?

Not an attack, just actually clueless.
