An AW101 undergoing VH-71 testing near the Lockheed facility in Owego, New York. Delays and engineering issues plagued the VH-71's development. [31] By 2007, the estimated cost of developing and modifying the aircraft had risen by 40% to $2.4 billion and had passed the $4.2 billion expected for the production of the fleet. [32]
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
In the late 1980s, GE also proposed a much larger turboprop, the T407/GLC38, with a five-stage axial/one-stage centrifugal mixed-flow compressor, an annular combustor with 15 burners; a two-stage compressor turbine, a three-stage power turbine, and max takeoff power of 6,000 shp (4,475 kW). The YT706 engine is based on the CT7-8A engine.

[ 15 ] [ 18 ] In June 2010, it was announced that AgustaWestland and Rostvertol would build a manufacturing plant in Tomilino , Moscow Region, where it was initially planned to ...
In August 2010, the Canadian Forces fleet of 14 CH-149 Cormorants passed 40,000 operational hours. The fleet had a higher flying rate than any other AW101 fleet and Cormorant 901, currently stationed at Canadian Forces Base Comox with 442 Squadron, has the highest number of airframe hours on any of the AW101s anywhere in the world.
