Nearly half of revenues at QinetiQ - the former research arm of the Ministry of Defence - now comes from the US. More than 60% of its 22% increase in pre-tax profits to £46 million in the half-year to the end of September was due to North America. The group, which has been parodied as being manned by Q-type figures from the James Bond films, has high hopes for its new Dragon Runner, a mini-version of Talon that can be carried on a soldier's back.
