The Tupolev Tu-155 is a modified Tupolev Tu-154 (СССР-85035) which was used as an alternative fuel testbed, and was the world's first experimental aircraft operating on hydrogen and later liquid natural gas. The similar Tu-156 was never built.
My idea of this that this aircraft can be a convertible aircraft ingame, just like how experimental variants of normal aircraft (ex: F-15 ACTIVE, etc)
