To simplify it: pretty much. I'm no expert, and can't think of many BTT missiles that have entered service. So, don't take what I say as gospel, but, use the terms to further your research - if you choose to.
This. Active radar missiles sensors are even more expensive, to say nothing of the battery required to power their radars
Yeah, I forgot all about the battery limits. Like being able to "warm-up" the seeker for an hour straight, all the while being radiation hardened with the ability to survive 100G+ lateral loads, etc. Oh, and it needs to do this while the IR focal plane array (FPA) is getting hit with 5000psi of -300 degree F argon/nitrogen to cool it down. Most people don't realize just how complicated seeker heads are, and how much it costs to make a reliable one that works as intended when you need to.
do missiles spin to change direction?
no they fly
They fly now?
They fly now.
Just the opposite. These missiles have air driven gyroscopes to not spin.
Arent these went out of use in new designs due to creating too much drag?
AIM-9X is steered with rear wings instead of front so kinda, roll control is electronic now.
i still cant visualize how missiles maneuver in the air while flying speed of sound
Rolerons are incredibly sexy engineering.
some do, most just use normal control surfaces

But how does the missile know where it is?
By know where you're mom isn't
Some do, they're called Bank-to-Turn (BTT), as opposed to Skid-to-Turn (STT).
so BTT rotates the whole missile sorta like a plane would? and I assume STT kinda keeps the missile flat and yaws it around to turn?
I didn't know this, neat.

Wait, so every shitty MANPAD actually has alien-tier tech in it?
>So do we need some kind of advanced guidance algorithms or
Na son. Just hold this angle with the target.
>cost 300k
how can this cost that much? Raytheon monopoly?
Sensors. You are ALWAYS paying for the sensors, and they're not cheap. For some missiles, you're looking at $300k+ JUST for the seeker head.
