On May 31, 2019 four United States Marine Corps MV-22B Ospreys departed Lajes Air Base in the Azores enroute to Caen in France to support the forthcoming visit of President Trump to Europe.
The four MV-22Bs belong to HMX-1 (Marine Helicopter Squadron One) and used callsigns "Knighthawk51-54":-
168302/06
168339/12
168324/09
168332/10
They were supported by three VMGR-252 (Marine Aerial Refueler Transport Squadron 252) KC-130Js:-
165810/BH
168071/BH
168069/BH
Other HMX-1 helicopters arrived in the UK a few days earlier in the shape of VH-3D Sea Kings which were air freighted into RAF Mildenhall, later flying on to Biggin Hill.
