A new £100 million "state-of-the-art" facility for the RAF's anti-submarine aircraft fleet has been handed over to the Ministry of Defence (MOD).
The facility at RAF Lossiemouth has taken two years to build and can hold up to three of the Air Force's eventual nine P-8A Poseidon aircraft.
It is more than 33,000 square metres in size and also has training and mission support facilities, including advanced simulators that are due to be delivered later this summer, and accommodation for two squadrons.
Minister for Defence Procurement Jeremy Quin said: "The new Poseidon fleet will reassert the UK in the maritime patrol arena.
"It will play an invaluable role in our national security for decades to come.
"The state-of-the-art Lossiemouth facility provides the fleet with an ideal base while helping to create and sustain jobs in Scotland."
The facility - a joint investment by Boeing and the MOD - was designed and built by the aerospace giant.
More than 300 people were involved in the building work at the peak of the project.
About 470 additional personnel will be based at RAF Lossiemouth in support of the Poseidon air fleet - taking the total number of personnel on the base to around 2,200.
Once the facility is fully operational, Boeing expects to have more than 200 employees focused on maintenance, training and support at the base.
Air Commodore Rich Barrow said: "The strategic facility at RAF Lossiemouth is going to be an outstanding working environment, optimised to support the RAF’s new Poseidon Maritime Patrol Aircraft.
"But more than that, it is going to be the home of our new capability where our crews, engineers, mission support staff and contractors will work together to deliver this essential defence output."
Both are flying from nearby Kinloss Barracks until the facility and new runway at Lossiemouth are formally opened later this year.
In April, the RAF announced one of the aircraft was ready for deployment.
The nine aircraft will cost the UK £3 billion in total and are expected to be in the UK by the end of 2021.
