Bell 407AH

In 2011, at the Heli-Expo exhibition, the American company Bell Helicopter Textron Inc. unveiled the Bell 407AH, a multipurpose reconnaissance and attack helicopter designed for special operation forces (SOF). It represents an armed, civilian-certified variant of the Bell 407, modified for use by government and clandestine units.

Advanced Armament and Sensors

The helicopter’s armament can be mounted on two Universal Weapons Pylon hardpoints, similar to those used on the OH-58D Kiowa Warrior. This includes combinations of a six-barrel 7.62mm Dillon Aero M134D-T (Titanium) or M134D-H (Hybrid) machine gun, or a three-barrel 12.7mm GAU-19/A or B machine gun. It also supports an M260 launcher with 7x70mm unguided rockets (capable of firing APKWS – Advanced Precision Kill Weapon System missiles) and an HMP-400 machine gun pod with a 12.7mm FN M3P machine gun and 400 rounds.

For reconnaissance missions, the Bell 407AH is equipped with a FLIR Systems Introduces Ultra 9HD thermal camera in its nose, offering a resolution of 1920×1080 pixels and compatibility with night vision goggles.

Innovative Design and Market Outcome

The Bell 407AH features a four-bladed main rotor, originally developed for the OH-58D (Model 406). Its blades and hub are constructed from composite material with an indefinite service life, providing superior performance and flight comfort compared to earlier models. Vibration-isolating measures are integrated into the main rotor pylon, and similar measures are applied to the skid landing gear structure to eliminate ground resonance.

In 2013, the helicopter was offered to the Iraqi Army. However, the military ultimately chose the more advanced Bell 407GT variant, which was based on the Bell 407GX. As a result, the Bell 407AH remained a single prototype, bearing serial number 53989 and registration number N407AH.
