Its max range in DCS appears to be ~150NM. Units with perfect SA refuse to fire it outside of that range. Beyond that, no comment.
They’re terrifying. Oodles of fun and terrifying. You can interdict them with F/A-18, but you have to be in a relatively advantageous position (they need to be coming to you), and ricky ticky tick on your reaction otherwise you don’t have to speed to catch them before they shoot, and you have no chance of catching them after. If the planets align and you’re in position, you can wreak some havoc. Right now the obstruction is without TWS, you’re limited in how much you can send down range in an extremely time constrained scenario.
All that said there’s a reason I’ve been sitting on that particular MP mission until the Tomcat comes out, and it’s not the Bug’s studly prowess as a fleet defense asset.
