Boeing’s UK Rotorcraft Support has initiated flight testing for the first Chinook Mk4. As part of Project JULIUS, Boeing and its Defence UK unit conducted the helicopter’s first flight on Dec. 9 in Hampshire, England. The project involves modifying 38 Mk2/2As into the Mk4/4A configuration and upgrading eight Mk3s into Mk5s. Subcontractor Vector Aerospace is updating the helicopters at its Gosport Fleetlands facility, including installation of Thales’ TopDeck avionics and a third crew seat.
