By 2013, products produced by Diehl Aerospace were reportedly integrated upon all Airbus-built airliners, as well as most Boeing-built counterparts as well.

[7] The company has also been active within the military sector; Diehl has supplied elements of both the NHIndustries NH90 helicopter and Eurofighter Typhoon multirole fighter aircraft.

[2] By 2013, Diehl was reportedly keen to expand its aerospace work in light of declining activity in the defense sector.

[8] In early 2012, aerospace periodical Flight International reported that the company was well-positioned to handle scheduled ramp-ups in output by both Boeing and Airbus alike.

[9][7] However, the interior equipment specialist AOA was acquired by the firm during the following year; Diehl subsequently reiterated that its main focus was on organic growth opportunities rather than via further acquisitions, but would be encouraging second- and third-tier suppliers to consolidate wherever possible.

The company stated that it planned to remain heavily engaged in the sector and to make further investments in its aviation business.
