Union members representing workers at BAE in Brough begin a three day trip to Westminster today to lobby MPs for support.
They want the Government to bring forward an order for replacement Hawk jets for the Red Arrows to save hundreds of jobs at the site.
BAE Systems announced that it is planning to cut almost 2,000 jobs in its military, maritime and intelligence services to give it "sharper" competitive edge.
Around 40% of a new Hawk is manufactured at the company's site at Brough, East Yorkshire, and the rest at Warton and Samlesbury in Lancashire.
MP for Brigg and Goole Andrew Percy said MPs had come together to ask the Government for help. He added: "To be really honest about this the solution to the problems at BAE will only come from international sales, that's the nature of this business. We do believe keeping Hawk production beyond 2019 is really important for us as a country."
