<p>A point that I think it’s important to talk about is SAMs and the effectiveness (and cost) thereof. There are some pretty bad SAMs in the game, but the one that I want to focus on is the <a href="https://www.reddit.com/r/worldpowers/comments/3e468y/news_avengers_shield_low_frequency_samads/">Avenger’s Shield</a> system in use by the EF, mostly because I’m in the EF and see a lot of it. I’ll use it as an example of what’s wrong with the common conception of SAM systems in operation, use, and deployment, as well as the physics inherent to the problem.</p>

<p>To understand a lot of the justification for the rest of this, you first have to understand why SAMs have ranges at all. As everyone knows, a missile will stop eventually (mostly, it won’t be able to stay airborne anymore). However, an interesting consequence of this is that as a missile slows down, the amount it can actually turn goes down, as the fins on
