WWII saw surface to air missiles in development but I don't think they were ever fielded. But shortly afterwards several nationa developed effective ground-based anti-aircraft missile systems.

Since Tin has almost no airforce as of now (they have no friendly nations to purchase the aircraft from) yet I mentioned that the government poured money into one or two military projects (one being the development of good submarines) I figured I'd have anti-air missiles be the other project. Granted this would make Tin relatively advanced in the category of anti-aircraft technologies, but that makes sense considering how badly they need that. With almost no fighter craft and their enemies in Avalia having a really good air force, it makes sense that Tin would have freaked out and came up with a way to mitigate their lack of air superiority.

So what I'm asking for is permission to have (slightly) advanced technology in this specific area. I think that in the real world missiles that could be fired from the ground and shoot down planes were developed by the early 1950's so this isn't too far from the general tech level.

And if this is fine, [@Hael] since your nation is also lacking in the air department do you want to have an international ballistics program between Tin and KalMea? That way we could both have oversized fireworks that can shoot down those pesky airships.
[/quote]WW2 had used anti-air missiles but your issue would be pretty much that they're unguided.
Anti-air missiles are also pretty far in the "aviation tech tree".
I can understand that you try for balance and to avoid being overwhelmed by the superior tech of others but actual guided missiles would be pretty much a gamebreaker.

If you want effective air defenses then invest in cannons on anti-aircraft mounts.
It also makes a lot of sense because Avalia pretty much sports a huge fleet of airships.
Such monstrosities would require you to use big anti-aircraft cannons to effectively bring down.
Something like the famous 88mm Flak 40, for example.
Side benefit that they are also pretty damn good fixed anti-tank defenses.
You can also try to cover anti-fighter defense by using quad-mounted AA machineguns.
These are all fine and reasonable for your nations. And should mostly do the trick.

...And man, you'd [u][b]need[/b][/u] AA defenses if I we actually face each other in battle. V-1 like flying bomb attacks can be nasty and that's what my airships can do.
