Little (No?) equipment is "Made in the UK" in any real sense.
Take the Challenger 2.
Made in Newcastle right?
Assembled in Newcastle.
The fire control computer was made by a Canadian company, now owned by General Dynamics.
The commanders sight is French, made by Sagem.
The gunners sight is made by Thales, also French.
The Engine was American, CAT via Perkins
The Gearbox was American, Textron via David Brown.
Both are now German, MTU and MAN (Renk)
Shells are made in Belgium.
