French logistics company CMA CGM Group has firmed its provisional order for four Airbus A350 freighters.
The operator had previously agreed a memorandum of understanding for the Rolls-Royce Trent XWB-powered aircraft.
Airbus says the company has formally firmed the deal for the twinjets.
They will add to the CMA CGM fleet of four A330-200Fs and a single converted A330-200, plus a planned pair of Boeing 777Fs.
The company recently established its own air freight operator, CMA CGM Air Cargo, to branch into the sector.
Its A330-200Fs are being operated by Air Belgium.
Airbus secured its first agreement for the A350 freighter – which will have a payload capability of 109t – during the Dubai air show, when lessor Air Lease agreed to take seven.
It has since obtained agreements for another seven from Singapore Airlines plus four for Air France.
