Yugoslav Helicopter Tech Tree


Post by @YugoSlav and @Black_Red_Baron

Today I would like to propose an independent Yugoslav helicopter tech tree.
It consists of helicopters that were/are used by the Yugoslav, Serbian, and Slovenian Air Force.

+1 because of unique helicopter armaments and had to be hard to find all different versions.

1 Like

You could add Croatian Mi-171Sh folded with Mi-17V5, to my knowlage Mi171Sh is export version of Mi-8AMTSh. In my short research i could only find pictures and text that mentions S-8 rockets, but if its really just a export Mi-8AMTSh(with out nose mounted 7.62) it could be added with all weapons of standard Mi-8AMTSh because as we all know that Gaijin does not care about historical armament, example F-4F with Aim-9J.

Question: why is OH-58 unused?

2 Likes

Because it doesn’t have a unique weapons loadout… Although the same can be said for Mi-35M, so I’ll most likely add the OH-58D after the Mi-17. Or maybe I should move Mi-35M after Mi-17 and add OH-58D after GAMA?

1 Like

What would be the loadout of the OH-58?

2 pylons with provisions to carry combinations of:

  • 1 x LAU-68 rocket launcher with 7 70mm Hydra 70 rockets
  • 2 x AGM-114 Hellfire missiles
  • 1 x 12.7 mm M3P heavy machine gun

It would slightly expand the tech tree, while it has no its own domestic srmament. If you think addition of OH-58 makes suggested Tech Tree more competitive then I believe such addition can be justified.

You know how gaijin is, they will add Mi-35M because they can just ctrl+c. And as we all know they will add as much helis they can(joke), but hear me out. Did you know that Serbia will get Mi-35P? You could add it to unused helis/folded with Mi-35M in TT.

Mi-17 → Mi-35M
GAMA → OH-58D
