High attrition
Perhaps the argument that the Afghans are not capable of training on American aircraft is a cover-up. Besides being two to three times as expensive as the Russian ones, American military helicopters have suffered numerous blowouts in both Iraq and Afghanistan. The high altitudes of Afghanistan have played havoc with helicopter equipment. For instance, in June 2013 a hailstorm damaged more than 80 US military helicopters, wrecking rotor blades, shattering windows and grounding aircraft for weeks.
Russia vs US: Comparable choppers
The Mi-17V5 is the export model of the Mi-8 – the most produced (12,000) and exported (3000) helicopter in the world. The chopper can be used as both a transport and gunship helicopter. It not only has an auxiliary engine but also an extra door on the right side, improving survivability.
The Russian chopper is nearly twice the size and weight of the equivalent American model, the Bell UH-1, although it only hauls about 50 per cent more cargo. But the additional weight constitutes a thicker skin and overall more protection from small arms fire. Earlier this year a Syrian Air Force Mi-17 was hit by an air-to-air missile fired by a Turkish Air Force fighter aircraft but the helicopter survived long enough for both Syrian pilots to bail out in their own airspace and avoid capture.
According to Strategy Page, while the American military replaced the UH-1 with the UH-60 in the 1980s, the Russians "just kept adding better engines and electronics" to the Mi-17's basic frame. And with the Russian aircraft costing about half as much as a UH-60, "if you want mobility for the least cost you get the Mi-17".
In fact, the push for the Mi-17 came from the very top of the US military establishment. Asked why the US doesn't supply the Afghans with American-made aircraft, US Joint Chiefs of Staff Chairman Gen. Martin Dempsey told Congress last summer: "There's no way we can put them in anything other than that helicopter."
