Iran's helicopters
Permalink Closed


TheZafar 300 attack helicopter, looking cheap and ugly as ever.

The Zafar 300 is an Iranian attack helicopter based upon the American Bell Model 206A Jetranger utility helicopter, adapted for a military gunship role. It is armed with a General Electric GAU-2B/A Minigun rotary six-barrel machinegun in an under-nose turret, and disposable stores on two hard points. The Zafar 300 is manned by a crew of two comprising a pilot and gunner seated in tandem.

In AirInternational recently a photo of the HESA Shahed 285 was shown.
Probably not a game changer on the battlefield, nevertheless an interesting
type, clearly based on the Bell Jet Ranger:

It was this one from AirInternational:
And sorry, I wasn't aware of the already existingn thread about Iranian

Thanks for the scan. I wish I could merge the threads but its not an available ActiveBoard feature yet. I should send them another request.

In order not to make things even more complicated, I'll post the sideviews of another
variant of the attack/recce version (with another, probably turnable gun installation)
and the 285C/AH-85C naval attack variant here:

Interesting, this reminds me of Cardoen's work on the armed Long Ranger variant.

AH-64 could blow those out of the sky easily. Poorly armed and cheaply built aircraft losely based on western utility design.

Avoid pointless replies like this. If you have more to say than just "yeah" or I agree", please post.

Like the Zafar 300?

Keep in mind it was only a prototype made during the war. It was never to be put into production.

The role of course going to theShahed 285 (here) instead, but its no prize either.

It miht be early to verbally trash the aircraft, I mean it looks like a cheap homemade chopper but it could be as agile as the OH-6 for all we know. Has it been test flown with success?

Zafar 300, definately no agility in comparison to the Hughes/MDD helicopters or even the Bell 206A it was based on.Shahed 285 on the other hand I just discovered thanks to the 'other' Iranian helicopter thread, but might actually improve upon the design of an assault platform like the Z-300 in terms of performance.

Regarding the side view of the Zafar 300, that thing looks like such an easy target for a RPG.

Here is the Shahed 274, a very unusual (though not very handsome) design. There is no reason to believe it was taken beyond the prototype stage.

This is the Shahed 278, a local type based upon the Bell Jet Ranger I think.

And finally, the Shahed 285, another Jet Ranger-based type but this time as a small armed helo:
