When I posted this a few days ago I was providing a heads-up for
the launch. The arrow headed vehicle that is being thrust into
space has no engine itself and minimal control ability
(thrusters). The rocket that sent it into space provides the
speed while the delta is responsible for re-entry and then
control down through the atmosphere to the intended target.

The down range speed then is not new, it is escape velocity
provided by the rocket. The media apparently does not get that
part.
