Aircraft program
20 tonne hybrid buoyant airship (previously designated LMH-1) combining lighter than air technology with four thrust vectoring engines, previously proposed variants include LMH-2 (90 tonne), and LMH-3 (500 tonne). Originally conceived by Lockheed Martin who then founded AT² Aerospace to continue it's development.
The aircraft as engineered: what it is built from, the systems it flies with, and its configuration — each box a theme.
Technical reference compiled with AI research; a value appears only where two independent research passes and a web fact-check agree. Gaps are deliberate.
