Four new RAF F-35 Lightning stealth fighter jets have landed in the UK.
The jets, which cost £92m each, made the 3,000-mile journey across the Atlantic from a US Marine Corps base in South Carolina.
The supersonic planes will be based at RAF Marham in Norfolk, where they are expected to be in operation by the end of December.
The UK's military has committed to purchasing 138 of the US planes from aviation company Lockheed Martin.
A fifth jet which set off from the US Marine base returned to South Carolina after the aircraft took fuel from an airborne RAF tanker.
The planes had been due to fly to the UK on Wednesday, but the mission was postponed due to adverse weather conditions.
They will be part of the recently reformed 617 squadron - nicknamed The Dambusters after one of the squadron's missions during World War Two.
