Got around to testing it a bit. It seems really hard to lock onto distant targets (especially off-bore), mainly due to the digital inputs' high sensitivity. Surely IRL it would have an analog input or a cumulative effect for the digital input. I could look into implementing the latter.

EDIT: Zooming in thankfully makes slewing onto a target much easier. Unfortunately there appear to be some guidance issues when engaging distant targets moving at high speed. The missile tries at all costs to overfly the target before flying down onto it, but if energy is insufficient to do so, it will stall out and miss, instead of falling back to a pure-pursuit and maintaining a max range glide attitude.
