The low-cost carrier has signed an agreement to lease two of the new aircraft with delivery due in spring 2018.
The news comes just a day after Norwegian announced a new Gatwick-Las Vegas route which launches on October 31, 2016.
Norwegian chief executive Bjorn Kjos said: “In order to offer customers more routes and make our intercontinental operation even more competitive, we need more brand new, cost-efficient aircraft.
“Our intercontinental operation is crucial to the company’s global growth and the creation of new jobs. The Dreamliner is a great airplane with high passenger comfort, long range, low fuel burn and reduced emissions.”
Norwegian currently operates eight 787-8 Dreamliners and two 787-9 Dreamliners.
Norwegian is also exercising 8 of its 100 Boeing 737 MAX8 purchase options. The group already has 100 such aircraft on firm order and is the European launch customer.
The Boeing 737 MAX8 is Boeing’s next generation short to medium-haul aircraft with longer range, enabling intercontinental flights.
