Diehl Defence GmbH & Co. KG is a German weapon manufacturer headquartered in Überlingen. It operates as a division of Diehl Stiftung and specializes in the production of missiles and ammunition.

Diehl BGT Defence was established in 2004 through the merger of Bodenseewerke Gerätetechnik GmbH and Diehl Munitionssysteme GmbH & Co. KG. In February 2017, Diehl BGT Defence and Diehl Defence Holding were integrated into Diehl Defence.{{cite press release|url=http://www.diehl.com/en/nc/diehl-defence/press/defence-business-under-single-roof.html|title=Defence business under single roof|publisher=Diehl Defence|date=1 February 2017|accessdate=6 February 2017|archive-url=https://web.archive.org/web/20170217173005/http://www.diehl.com/en/nc/diehl-defence/press/defence-business-under-single-roof.html|archive-date=17 February 2017|url-status=dead}}

In 1960, Bodenseewerke Gerätetechnik became the lead contractor for producing the American Sidewinder AIM-9B air-to-air missile in Europe.{{Cite journal |last=Donnelly |first=Micky |date=1988 |title=Tony Bevan, Orchard Gallery Derry 31 March - 26 April 1988 |url=http://dx.doi.org/10.2307/25557326 |journal=Circa |issue=40 |pages=40 |doi=10.2307/25557326 |issn=0263-9475|url-access=subscription }}

Building on the knowledge gained from the Sidewinder's infrared homing technology, Diehl Defence developed the seeker system for the IRIS-T short-range air-to-air missile. Introduced in 2005, the IRIS-T has been adopted by 13 countries as of October 2022."Germany tees-off with Iris". Archived from the original on 10 September 2017. Retrieved 11 June 2014.
