Washington DC, 31/8: The US Army has grounded its entire fleet of Chinook helicopters, a battlefield workhorse since the 1960s, over the risk of engine fires, a media report said on Tuesday.
The Wall Street Journal, which broke the story, said such an extreme step was taken out of abundance of caution.
India has about 15 CH-47 Chinook helicopters. Over the past few years, they have emerged as one of the major military tools for airlift operations in places like Ladakh and Siachen glaciers to assist Indian forces deployed in these regions.
