ABOUT US

MRAS is a world leading manufacturer of complex aerostructures including nacelle systems and specialized structural components of the airframe. It supplies and supports these products for engine makers, airplane manufacturers and aircraft operators.

Located on Maryland’s Chesapeake Bay near Baltimore, MRAS has a 1.4-million sq. ft. facility situated on 180 acres – where the company and its predecessors have designed, built and equipped civil and military aircraft for 95 years.

In addition to MRAS’ design, development and manufacturing capabilities, the company provides technical support, spares and other services for its products. This includes the company’s authorization as an FAA/EASA Part 145 Repair Station for the maintenance, repair and overhaul (MRO) of nacelle systems on CFM International CFM56-7B and International Aero Engines V2500 engines, which power two widely-used single-aisle category jetliners: Boeing’s 737NG and the Airbus A320 family, respectively.

In 2019, MRAS was acquired by ST Engineering North America, the U.S. affiliate of Singapore-based ST Engineering – becoming a part of its global network of aerospace facilities and offices. With the ownership change, the company was renamed Middle River Aerostructure Systems.
