Design and development

The Shahed 285 is based on the composite Shahed-278, which is a relatively light helicopter with 682 kg empty weight, derived from the Bell 206 Jetranger. Compared to the American OH-58 Kiowa which retains the airframe of the Bell 206, the Shahed 285 is a single-seater with a narrower fuselage, but retains the tail and powerplant / rotor structures, and is intended for military use. Although designed by the IRGC, this helicopter is scheduled to be produced by HESA.[1]

Shahed 285 comes in two variants. AH-85A which is a land based variant and AH-85C which is a naval one. AH-85A is armed with 14 2.75 inch rockets and a PKMT light machine gun either on a rotatable turret or on a static mount, or an NSV heavy machine gun in an underfuselage gondola (latest version). It also uses an EO/IR camera on its top.

Instead of the machine gun, AH-85C has a search and track radar on its chin to find and track enemy ships. Its range is estimated between 30–40 km. It either uses two Kowsar or eight Sadid-1 anti-ship missiles. To fire these missiles, AH-85C relies on a Multi-function display in its cockpit.[2]

gollark: Since you have to jump through hoops to install cabling etc., and lobbying apparently got municipal ISPs banned in many places.
gollark: Those are not, as far as I know, actually that competitive.
gollark: There's just a lot of waste on stuff like advertising and reinventing things done by competitors which is at least theoretically avoidable.
gollark: No, we have perfectly functional competitive markets for things like food and TVs and furniture and whatever.
gollark: Central planning instead of our competitive systems could be way more efficient, except the incentives don't really work and nobody can be trusted to do it.
