The Panha 2091"Toufan" is an Iranian overhaul and upgrade of the BellAH-1J Sea Cobra light-attack helicopters purchased before the 1979 Islamic Revolution. The overhaul and upgrade program is known as project number 2091 of the Iranian Helicopter Support and Renewal Company (Panha).
The upgraded attack helicopter has a narrower airframe for greater flexibility and is armed with M197 3-barreled 20-mm "Gatling-type" cannon in the A/A49E turret. Its wing-stub stations carry a pair of 19-tube 70-mm rocket launchers. The rear section has a Vulcan-type 20-mm automatic cannon, and two clusters of 38 anti-tank 70-mm missiles.
Bullet-proof glass protects the pilot's cockpit and weapons officer station, internal avionics have been revamped with the addition of a GPS and receiver in the nose, and a warning radar attached to the rear, with four antennae providing 360 degrees coverage and all electronics systems integrated.
