A Cessna Citation in military colours, moving staff between bases. Live UC-35 positions.
The UC-35 is the jet equivalent of the C-12: a straightforward business aircraft bought off the shelf to move small numbers of people quickly. The US Army and Marine Corps both operate them, and the appeal is simply that a jet does in ninety minutes what a King Air does in three hours.
Because the missions are administrative, the flying is predictable — short sectors between military airfields, usually in the mid twenties or low thirties, on weekday schedules. It is not a glamorous aircraft and it makes no attempt to be.
The C560 designator covers the Citation V, Ultra and Encore family, so civil examples appear as well.
The A is the Army's Citation Ultra and the D the Marine Corps' Citation Encore. Both are variants of the same Cessna family and both report as C560.
They are cheap, available immediately and well supported commercially. For moving a handful of staff between bases there is no advantage in a purpose-built military design.
Mostly not. They carry staff officers and urgent passengers rather than heads of state; that role belongs to the C-32 and C-37.
