French patrol planes are scouring the seas off Scotland for a Russian submarine after Britain was forced to call on allies for help because it has scrapped its own sub-hunting aircraft, Joinfo.ua reports with the reference to Independent.
The Russian vessel has evaded detection for at least 10 days after it was detected off the coast.
The submarine is feared to be spying on Trident, the UK’s nuclear deterrent.
The search intensified over the weekend as a second a French Atlantique II maritime patrol plane and a Canadian aircraft joined the hunt.
The Royal Navy frigate HMS Sutherland, and a hunter killer submarine, are also patrolling the area.
But Britain’s allies were called on to search for the sub from the air as the UK scrapped its own Nimrod sub-hunting aircraft in 2010 following a defense spending review.
The Ministry of Defense has not commented on the hunt for the Russian submarine.
The spokesman of the Ministry said: “We can confirm that allied maritime patrol aircraft based at RAF Lossiemouth for a limited period are conducting activity with the Royal Navy.”
“We do not discuss the detail of maritime operations.”
