An E-6B Mercury aircraft, which serves as the US Navy's air command post, landed in Iceland on February 28.

It is noted that while in Iceland, members of the aircraft's crew met with the US ambassador and other diplomats and military personnel, Caliber.Az reports citing the US European Command’s Twitter page.

The E-6B Mercury is a US military strategic control and communications aircraft and the US Navy's air command post. It is also called a "doomsday aircraft".

It is designed to communicate with nuclear-powered strategic submarines that carry intercontinental ballistic missiles. These are Ohio-class submarines. Each submarine can carry up to 24 Trident II D5 missiles capable of carrying nuclear warheads.
