(
Persian
:
???? ???
) is a light

Design and development
[

The Shahed 285 is based on the composite
Shahed-278
, which is a relatively light helicopter with 682 kg (1,504 lb) empty weight, derived from the
Bell 206
Jetranger.
[1]
Compared to the American
OH-58 Kiowa
that 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
.

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 in (70 mm) 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 (19?25 mi). 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.
