NASA’s Armstrong Flight Research Center (AFRC) in California is requesting information from qualified vendors for structural modifications to a Gulfstream V aircraft, supporting the agency’s Airborne Science Program. The project aims to adapt the aircraft (Serial Number 570) to accommodate scientific instruments requiring unobstructed downward observation of Earth.
The modifications will include the installation of two nadir
viewports—specialized windows allowing instruments to capture data from
directly below the aircraft. To ensure precision and efficiency, AFRC plans to
leverage existing technical data from a prior modification project on a
Gulfstream V with Serial Number 672. Design deviations will be limited to
maintain consistency with the earlier work, which also focused on nadir
viewpoint configurations.
Aircraft system relocations will be necessary to provide
clearance for the optical viewports, ensuring the performance of onboard
scientific equipment. These adjustments are critical for missions involving
Earth science, atmospheric research, and environmental monitoring, where
downward-facing sensors collect data on climate patterns, ocean dynamics, and
terrestrial ecosystems.
Firms with expertise in aerospace modifications, structural
engineering, or avionics integration are invited to submit capability
statements demonstrating their qualifications to undertake the
project. Interested parties must respond by Jan. 20 to be
considered. NASA emphasizes that no formal solicitation document exists at this
stage.
The Airborne Science Program relies on high-altitude
platforms like Gulfstream V to conduct research in support of NASA’s Earth
Science Division and other scientific initiatives. These aircraft serve as
airborne laboratories, enabling data collection in regions inaccessible to
satellites or ground-based instruments.
NASA detailed the work in a Sources Sought document released
this week. The announcement is categorized as a pre-solicitation synopsis,
intended for informational and planning purposes. Final contract decisions will
depend on evaluations of submitted capability statements and follow-up
discussions with prospective vendors.
