Well bro airdefence is Iran's top prioty so it's no suprise we have so many projects. But we can split them (generally speaking) into two groups: IRGC projects and Katam al binya air defence base projects.
Katam al binya air defence base has these indigenous projects that we know of:
Bavar-373 (range >200km) consisting of sayyad-4 missiles or perhaps other missiles too.
Talash air defence (range 60-200km)consisting of sayyad 2 and 3 missiles.
IRGC has:
Ra'ad which consist of 3rd of khordad and Tabas. They use medium ranged high altitude Taer missiles. 50km range and 25km altitude.There are different versions of Taer missiles.
They are also working on a 100km and 200km ranged missiles of which the sadid-630 may be one of them.
Now these units are not isolated. The IRGC works with Katam al binya air defence base.
And of course Iran has countless indigenously designed radars like OTH ghadir, sepehr, kayhan. And so many others radars like Nazir etc.
So we can say, Iran's integrated air defence is truly of the best in the world without a doubt.
Bavar-373 will start mass production next year. Next year's parade you'll see it for sure. Don't worry, we're all eagerly waiting its final arrival
