AARO's all-domain mandate — the substantive scope across airborne, transmedium, submerged, and space environments

One of the substantively distinctive features of the contemporary AARO framework — and one of the principal expansions over the predecessor UAPTF airborne-focused mandate — is the all-domain scope of the office's institutional engagement. The "all-domain" mandate substantively covers airborne, transmedium (objects that appear to operate across the air-water interface), submerged (objects that appear to operate in undersea environments), and space (objects that appear to operate in or near space environments) categories of UAP cases. The substantive scope is one of the principal structural features of the contemporary framework that distinguishes it from the historical Project Blue Book-era institutional engagement.

The substantive significance of each domain category

The airborne category is the principal historical and contemporary focus of UAP institutional engagement — the substantial majority of historical and contemporary cases involve airborne phenomena, and the analytical and investigative methodologies are most developed for this category. The transmedium category — objects that appear to transition between air and water environments — is a substantively smaller but distinctively important category. The most-cited contemporary cases in this category include the US Navy Roosevelt-era observations of objects that appeared to transition between airspace and undersea operations, and the historical Shag Harbour Canadian water-entry case of 1967.

The submerged category — Unidentified Submerged Objects, sometimes referred to as USOs in the historical literature — involves cases of unidentified objects operating in undersea environments and is substantively important because of the substantial classified US Navy operational interest in undersea environments. The space category — objects in or near space environments — is substantively important because of the substantial commercial and military space activity that the contemporary period has produced, and because of the unusual perceptual and analytical challenges associated with observations from or in space environments.

The all-domain expansion's substantive implications

The substantive implications of the all-domain expansion include several substantive features. The institutional engagement framework can now address cases that span multiple environmental categories — particularly transmedium cases that the airborne-only predecessor framework had substantial difficulty handling. The analytical methodologies can be developed across the broader environmental scope, with cross-category methodological insights that the single-category predecessor frameworks could not develop. The institutional coordination requirements across the relevant US military components (Air Force, Navy, Space Force, and other) are substantially more complex but the institutional capability for handling such coordination is substantially greater than it was prior to AARO's establishment.

The expansion also produces substantive challenges. The substantively different operational contexts of the various environmental domains require substantively different analytical approaches, and the institutional resources allocated to the broader scope operate across substantially expanded operational territory.

The mandate's continuing development

The all-domain AARO mandate is substantively distinctive in the international institutional landscape. The international peer frameworks (French GEIPAN, Brazilian FAB, Chilean CEFAA, Argentine CEFAe, and others) substantially operate within airborne-focused or aviation-focused institutional scope; the AARO all-domain scope is the broadest of the operating contemporary national institutional frameworks.

The continued substantive development of the all-domain capability across AARO's continuing operational life will continue to shape the contemporary US institutional engagement with the topic. The substantive expansion of analytical methodology across the broader environmental scope, the substantive operational coordination with the relevant US military components, and the substantive case-handling experience across the broader scope are all substantive trajectories along which the contemporary US institutional engagement is continuing to develop.
