AN operation designed to test the response of Nato against missile threats has begun off the Outer Hebrides.

The first ever “live fire” exercise of its kind in European waters will see Nato forces test their defences against incoming ballistic missiles. The US 6th Fleet is leading the exercise, the second time this year that US Navy ships have taken part in exercises off the coast of Scotland.

Nato announced yesterday that Operation Formidable Shield got under way successfully on Sunday at the Hebrides Range, a large area of sea used for testing missile systems which was recently used to test a new Royal Navy air missile defence system. Operation Formidable Shield will merge into the annual UK-led Joint Warrior exercise which starts later this week.

The operation involves ships and aircraft from the USA, UK, Canada, France, Germany, Italy, the Netherlands, and Spain. Some 14 ships, ten aircraft and around 3300 personnel will be involved in the exercise.

Nato stated yesterday: “Formidable Shield will see Allied ships detect-ing, tracking and defending against a range of anti-ship and ballistic missiles using Nato command and control procedures.

“Drills will include sharing a common tactical picture, conducting joint mission planning and engagement co-ordination. The live-fire naval exercise will be the first time in Europe that Allies practice defending against incoming ballistic missiles with no prior warning.

“Maritime patrol aircraft and Nato AWACS surveillance aircraft will provide aerial over-watch and ensure that the airspace is clear.”

Among vessels reported to be taking part are the Dutch navy’s HNLMS De Ruyter which is being given the task of tracking weapons fired from a US guided missile destroyer.

The much larger Joint Warrior exercise is set to begin this weekend.

Operation Formidable Shield is the latest piece in a missile defence jigsaw which Nato began to put together seven years ago.

The organisation stated: “Nato missile defence links Allied sensors and weapons together in a single system. Major components of Nato missile defence include four US Navy destroyers with the ‘Aegis’ missile defence system home-ported in Rota, Spain and a US operated land-based system in Romania known as ‘Aegis Ashore’.”
