Submarines and aircraft carriers have been spotted by our Largs News Camera Club members over the past few days.
The submarine, accompanied by MOD craft, was captured sailing up the channel between Cumbrae and Bute.
The great snap was taken by photographer Francesca Pearce, and it was not the only military vessel on th Firth of Clyde this week.
The mammoth HMS Queen Elizabeth aircraft carrier was also spotted sailing in the area.
Camera club member Jack Boyle captured the Royal Navy's flagship vessel as it sailed past Largs.
A number of military vessels from different nations have been spotted along the Firth of Clyde in recent weeks due to a major exercise taking place in the North Sea.
Exercise Formidable Shield saw vessels, aircraft and soldiers from multiple nations train in the North Atlantic.
The exercise ran from May 8 to 13, and gave nations and units practice of working together with live fire exercises against ballistic and air targets.
