Bristling with missiles systems, radars and anti-aircraft weaponry, Cardiff Bay from today is set to become home to an unusual vehicle parking arrangement.

Lined up in Roath Basin will be warships from six different countries collectively displaying billions of pounds worth of weaponry.

Yesterday, US military helicopters were seen circling the skies of South Wales ahead of the Nato Summit on Thursday and Friday.

Costing £1bn alone, the Royal Navy’s newest Type 45 destroyer, HMS Duncan, will arrive in Roath Lock, Cardiff Bay, at at around 1pm.

The M-05 Viesturs ship from Latvia, a minehunter, is currently already docked at the site.

It is set to be joined by Dutch minesweeper HNLMS Urk, a superfast missile patrol boat decked out in camouflage colours called HNoMS Skudd from Norway, German-built minesweeper LNS Kursis from Lithuania and the latest French vessel to hold the historic name La Motte Picquet.

La Motte Piquet is one of the most famous names in the French navy having been held by four ships named in honour of the 18th Century admiral Count Toussaint-Guillaume Piquet de la Motte. The current vessel to hold the name is an anti-submarine destroyer.

The Royal Navy’s HMS Biter patrol boat and HMS Express fast patrol boat will also be part of the contingent.

Cardiff Bay and HMS Duncan is set to be the location for one of the three working dinners taking place in the capital on Thursday evening.

Fences similar to the one erected in Cardiff City Centre have also appeared around Roath Lock, with residents reporting seeing armed and non-armed police in the bay area.

The bulk of the business of the summit will take place in the Celtic Manor Resort in Newport.

Yesterday people in Cardiff were given a surprise when a number of helicopters, including the vehicle that acts as Marine One when it carries the US president, were seen hovering over the city and landing at Bute Park.
