Ah ha, I found my source. Combat Aircraft Monthly seems reliable to me, so I kinda took what it featured at face value...(Nov 2014 issue)
- Two 2000shp GE T700-GE-701D engines. More powerful, better fuel efficiency, able to hover in a wider range of conditions. Less power-limited.
- Capable of IMC operations
- Soon to be added to the E model: Link-16, improved missile warning system, improve sensors and UAV communication and control.
Sorry, I don't think this illuminates much in terms of the WAH-64D though...
