Esterline Belgium (formerly Barco Defense & Aerospace) signed an agreement with Lockheed Martin as part of the F-16 Replacement Program’s Essential Security Interests. Through this agreement, both companies will seek to develop further long-term partnerships if the Belgian government decides to choose the F-35 as successor for its F-16s. This partnership will mainly concern avionics and rugged display products.

In September 2015, Esterline Belgium, together with Ilias Solutions, Sabca and Sonaca, concluded an initial agreement with Lockheed Martin to seek further collaborations in the framework of the F-16 replacement program.
