A military exercise involving 55 warships and submarines, 70 aircraft and around 13,000 personnel will take place off the west and east coast of Scotland next week.
The massive bi-annual exercise involving the Royal Navy, British Army and Royal Air Force is set to take place across various UK locations.
There will be significant naval and aerial activity off the west and east coast of Scotland, including amphibious landings on the west coast.
Part of the exercise will be training in temporary radar and communication jamming.
GPS jamming will be limited to a confined area in the north west of Scotland and the relevant authorities, including aviation and maritime communities, have been consulted and procedures are in place for any unforeseen activity that might arise.
Aircraft will operate from locations including RAF Brize Norton, RAF Waddington, RAF Marham, RAF Leeming and RAF Lossiemouth.
Elsewhere there will be aerial and ground activity including airborne landings around Salisbury Plain in England and several other Defence Estate areas in Scotland, northern England, south Wales and central England.
