At nearly 8,000 metres squared, the Central Training Facility will include a teaching block, classrooms, offices, craft workshops and welfare facilities.
Construction work has already begun at the site in Barrow-in-Furness, which is home to the UK’s submarine design and build capability.
The facility will also serve as a training facility for BAE’s wider workforce.

Tony Johns, managing director of BAE Systems Submarines, said: “The design and build of a nuclear powered submarine is one of the world's most complex and technically demanding engineering challenges.
“It's vital we have the right people with the right skills to deliver these programmes. This investment underlines our commitment to the future. The new facility will provide a modern learning environment to supplement the training our apprentices already receive."
Defence secretary Michael Fallon met with apprentices on Monday who are working on Britain’s new submarines and will benefit from the training facility.

Fallon said: "This investment demonstrates the benefits that our growing defence budget brings for highly skilled jobs in the North West and across the country.
"It will ensure we have people with the skills necessary to deliver one of the most complex programmes in the world that will help modernise our fleet of nuclear submarines."
