HALO Home     02 Apr 2015

Welcome to the HALO homepage. These web pages are currently undergoing a major overhaul. We will be restructuring existing information and add more information on current and planned projects and missions with HALO. For the time being (April 2015) you might find a few broken links or empty pages. This will be corrected as soon as possible.


The High Altitude and LOng Range (HALO) Research Aircraft is the new research aircraft for atmospheric research and earth observation of the German Science Community. HALO was funded by the Federal Ministry of Education and Research, the Helmholtz-Gemeinschaft and the Max-Planck-Gesellschaft.

HALO is based on a production G550 business jet from Gulfstream Aerospace Cooperation. Gulfstream was responsible for the construction of the green aircraft. Modifications to transform the regular business jet into a research aircraft were made by Gulfstream as well as the RUAG company in Oberpfaffenhofen.

The aircraft is operated by the Flight Experiments facility of DLR (Deutsches Zentrum für Luft- und Raumfahrt; German Aerospace Center) in Oberpfaffenhofen.

HALO arriving on January 24, 2009, in Oberpfaffenhofen.
