Airbus has confirmed that 1,100 jobs will be cut at its Filton plant near Bristol.
Most of the losses will be among support workers, and the posts will go over the next three years.
Job losses are also planned at the Broughton plant. In February, Airbus revealed plans to shed 10,000 jobs across Europe in the next four years.
Delays in the project to build the A380 superjumbo are set to cost the firm at least 4.8bn euros.
The plane's wings, landing gear and fuel management are all designed at the Filton site.
