\section{\ref{sec:VHE-LHC} Upgrade at higher energy : The VHE-LHC}  \label{sec:VHE-LHC}  Precision measurements constitute only one facet of a sound high-energy-physics project for the future. They need to be complemented with direct searches for new phenomena at an energy-frontier facility, to possibly answer fundamental questions that will unavoidably arise from these precision measurements. Both the $\epem$ Higgs factories discussed in Section~\ref{sec:Higgs} are accompanied by high-energy upgrade projects. For the ILC, it is foreseen to double its length to reach a centre-of-mass energy of 500 GeV, and it is not yet excluded to extend it by another factor of two towards $\sqrt{s} =$ 1 TeV. Another linear collider project, CLIC~\cite{cite:CLICDR}, could also take over for the high-energy physics programme all the way to $\sqrt{s}=$ 3 TeV.
