Specifications

Everything BAE has released — and everything they haven't.

Brontanax was rolled out as a pre-production Operational Concept Demonstrator. BAE has intentionally kept detailed performance figures classified. What follows is drawn only from the Farnborough 2026 briefing and reputable defence-press reporting.
