Kuwait has officially signed an order for 30 Airbus Helicopters H225Ms, with the heavy twins now in the airframer's firm backlog, FlightGlobal understands.
Although the Gulf state selected the Caracal in August 2016, the deal had not been finalised by year-end.
Speaking in late January, Guillaume Faury, the airframer's chief executive, indicated that the €1.7 billion ($1.8 billion) contract would be ratified "over the next few weeks".
FlightGlobal understands that the order was firmed up during the first quarter.
Airbus Helicopters declines to comment on the status of the deal, however.
The aerospace group is due to report its first-quarter results on 27 April, when more detail on the helicopter division's backlog will be revealed.
There will also be more clarity over the financial impact of the continued grounding of the civil H225 in Norway and the UK.
Those flight restrictions were put in place in the aftermath of a fatal crash on Norway's west coast almost a year ago, on 29 April 2016.
Norwegian accident investigators are due to give an update on the status of their probe this Friday.
