With one aircraft in International Falls (MN)undergoing cold
weather evaluation flights (and it doesn't get much colder than in
International Falls) and the other two conducting test flights at
the Patuxent River Naval Air Station (MD), the AH-1Z test fleet
exceeded 1,000 flight hours last week.
The AH-1Z Super Cobra is the attack helicopter component of the
Marine Corps' H-1 Upgrade program to remanufacture the existing
AH-1W SuperCobra and UH-1N twin-engine Huey into the 84 percent
identical AH-1Z and UH-1Y configurations.
