Boeing in export discussions for AH-6i

Boeing is currently engaged in discussions with a number of potential Middle East, South-Asian and Asia-Pacific customers regarding its AH-6i Little Bird light attack/armed reconnaissance helicopter.
The company's AH-6i Capture Team Leader, William Jernigan Jr, told Jane's at the Singapore Air Show on 5 February that it is looking at a Middle East & South Asian market of 24 helicopters per customer country and expects similar numbers for the Asia-Pacific region. He declined to specify who these customers might be.
Jernigan feels that the AH-6i will be a cost-effective solution for many countries, particularly as several could be purchased for the price of any one of the current heavier attack helicopters.
Boeing has been able to keep the unit price low by utilising many of the Block III Apache's systems (there is 80 per cent commonality in the display consoles of the two platforms), although Jernigan declined to state what the exact unit price might be.
He added that, beyond the military market, there is potential for unarmed AH-6is to be sold to civil authorities, given the capabilities of the integrated electro-optic/infrared (EO/IR) L-3 Wescam MX-15Di sensor system, which could be used for surveillance or search-and-rescue missions.
The AH-6i features a Rolls-Royce C30R/3M engine with 850 shp, giving it a better payload capability than the existing MH/AH-6s currently in US military service. The AH-6i's more powerful engine will also enable it to cope better with the high temperatures of the Middle East and Afghanistan.
The AH-6i's armament options include 7.62 mm or .50 cal miniguns, 70 mm (2.75 inch) rocket pods or Lockheed Martin's Direct Attack Guided Rocket (DAGR) and AGM-114 Hellfire missiles. Jernigan stated that, if required, the AH-6i could carry Stinger missiles for self-defence and also that it could easily be modified to carry any non-US helicopter weapon systems.
Also installed is a laser pointer that can be seen by ground troops with night-vision goggles, in order to overcome the disparity between having vision enhancement for ground personnel and IR for the aircraft. In addition, the MX-15Di has a laser designator and laser rangefinder as well as an eye-safe laser for training purposes.
To enable the fitting of additional avionics systems, the AH-6i's nose is more pointed than that of the standard variant, providing extra space between the display console and the front of the airframe. Valuable cabin space has been saved by a reduction in the number of system boxes required to control the wing-mounted stores, from four in the older aircraft to one in the AH-6i.
The new Little Bird variant features a 'glass cockpit'; the aircraft's main flight control and sensor information is presented to the pilot on two L-3 Communications multifunction displays mounted in the centrally located display console, which is accessible to both pilots. Boeing has not installed a standard radio fit on the AH-6i as the company has found that its international AH-64 customers usually opt to use their own radios. Two multiband commercial radios, which can easily be replaced, have therefore been fitted as a stop-gap measure.
With the additional avionics fitted in the nose of the aircraft, the rear cabin bay remains empty and can accommodate two people. Alternatively, the cabin can be used for additional ammunition or auxiliary fuel tanks.
In addition to the ballistically tolerant 62-US-gallon (235-litre) main internal fuel tank, the AH-6i can be fitted with up to three more tanks of different types, to increase its range and/or time on station. The 'T-tank' (27.5 US gallons), Goliath tank (62 US gallons) and side-mounted external tanks (two tanks each holding 31 US gallons) are already proven on the aircraft and are in use with US special forces on the MH-6 helicopter.
For increased survivability the AH-6i is configured to carry the AN/AAR-47 missile approach warning system (MAWS) and countermeasures as well as Wulfsberg RT5000/C5000 and LN251 INU/GPS enhanced communication and navigation equipment.
Although an in-service date (ISD) has not been announced, Jernigan previously told Jane's that, with the production line for the commercial MD500 variant already up and running, a launch customer for the AH-6i would be able to take delivery of its first aircraft within 21 months of signing a contract.
