In 2008 the size of the National Barrier Asset was tripled to meet expected demands. It came to prominence for the 2014 NATO Summit, when it was erected around the Celtic Manor in Newport and in parts of Cardiff. In June 2015 it was announced that around 2 miles (4 kilometres) of the asset would be sent to Calais to help prevent illegal immigration to the United Kingdom. In 2017, Police Scotland deployed the asset in Edinburgh ahead of the Fringe festival.
