Textron Aviation took the opportunity at the Paris Air Show 2017 to showcase multiple defense and special mission aircraft including the French Customs Beechcraft King Air 350ER. The craft has a Beechcraft-built radome, a EO/IR lift, and ISR consoles. It excels at surveillance missions.
Other features include drop-hatches for releasing lift rafts, flares and markers. The 350ER also features a bubble window kit which replaces the aft-most windows with protruding windows allowing for better observation.
Beechcraft features detailed information of the 350ER at their website: http://beechcraft.txtav.com/en/king-air-350er
