AX-9 Seraph / Sixth-generation air dominance

The sky,re-engineered.

Aethon designs, builds and flies sixth-generation aircraft. Tailless. Adaptive. Autonomous when it needs to be.

01Mission

We didn't upgrade the fighter jet. We started over: an airframe that thinks, an engine that changes its mind, and a skin that disappears.

Threeaircraft.One mind.

A crewed fighter, an autonomous wingman and a hypersonic scout, linked by ORACLE into a single nervous system.

Seraph

Crewed: 1 pilot + ORACLE

A tailless lambda wing wrapped around two adaptive cycle engines and an AI co-pilot that never blinks. Built to take the high ground, and keep it.

Wraith

Uncrewed: flies in packs of four

Attritable, autonomous and unnervingly coordinated. Four Wraiths fly ahead of every Seraph, sensing, jamming and taking the risk so the pilot doesn't have to.

A waverider built for the thin air between the sky and orbit. Solstice crosses an ocean in the time it takes to brief the mission.

An engine thatchanges its mind.

A third airflow stream opens and closes in flight, so one engine behaves like three: frugal on the long transit, relentless at supercruise, violent when it counts.
