Boeing and MT Aerospace sign SLS contract

(17 Mar 2022) Boeing and MT Aerospace AG, a subsidiary of OHB SE, have signed a further contract to supply structural components for NASA's Space Launch System (SLS). Boeing is the industrial prime contractor for the development and construction of this heavy-lift launch vehicle, whose first flight is scheduled for spring 2022.

Boeing has now commissioned Augsburg-based MT Aerospace with the dome segments for the cryogenic hydrogen tank of the rocket's upper stage EUS (Exploration Upper Stage), thus expanding the existing co-operation between the companies. The EUS upper stage is intended for the exploration missions planned in NASA's Artemis programme. One of the goals of the Artemis programme is to create a sustainable presence on the moon.

MT Aerospace AG currently produces dome gore panels for the main stage of NASA's SLS. Tank systems represent a safety-critical element, which is why the highest quality standards apply to materials and manufacturing processes.

The Augsburg-based company is now also responsible for the holistic, high-precision 3D manufacturing process of the aluminium-lithium alloy dome segments for the cryogenic hydrogen tank of the EUS upper stage. The individual segments are joined in the USA to form the huge tank domes (diameter 8.40 m), which are then integrated into the launch vehicle.
