An aerospace company has announced a £57m investment in aircraft maintenance facilities next to Prestwick Airport.

GE Aerospace is spending £30m on the expansion and modernisation of its maintenance, repair and overhaul (MRO) site in the South Ayrshire town.

This will include the construction of a new 55,000 sq ft (5109 sq m) building. The work is due to be completed by the start of 2028.

The project is being supported by £27m from the Ayrshire Growth Deal. Scottish Enterprise has also planned to invest £6m.

The investment is expected to create about 150 new jobs over the next five years.

GE Aerospace said the upgrade will boost capacity and "operational flow" at the site, enabling it to better support customers across the firm's commercial MRO network.

Andy Prow, site leader at GE Aerospace in Prestwick, said: "This investment reflects GE Aerospace's commitment to our customers and to the future of our Prestwick site.

"By expanding and modernising the facility with the help of government partners, we are improving capacity, operational flow and readiness for future demand, while helping hire and train additional workers from the area."

South Ayrshire Council leader Brian Connolly described the investment as a "major milestone" for the Ayrshire Growth Deal, which will "significantly benefit" the local and national economy.

GE Aerospace has also announced a donation of £75,000 to Ayrshire College to support new training equipment for around 150 students and apprentices, which it said would help secure the next generation of aerospace skills.

The money will also support the delivery of a course designed to prepare students for careers in the wider aerospace industry.

Deputy First Minister Jenny Gilruth said the "major expansion" would be a real boost for the local economy.

She said: "It is also a vote of confidence in Scotland's workforce, and our support for this expansion clearly demonstrates our commitment to build on the strengths of our advanced manufacturing and engineering sectors, as well as stressing the importance of the aerospace sector."

UK minister Melanie Ward said the UK government has also invested £32m in the Ayrshire growth deal to deliver a long-term future for Prestwick Airport.

Reuben Aitken from Scottish Enterprise said the investment builds on "decades of engineering expertise at Prestwick and the site's role within its global operations".

The US company also has bases in Cardiff and Hounslow.

In 2025, GE Aerospace also announced a £14.2m investment at its Wales site over three years, to improve infrastructure there.
