Airbus Defense and Space (the aerospace conglomerate formerly known as Astrium) is considering incorporating partial reusability into future Ariane rockets.
The move is believed to be a reaction to competition from SpaceX.
Airbus would not recover the entire first stage, like SpaceX, but only the lower portion with engines, pumps, and electronics. Tanks would still be expended. Airbus says the recovered portion represents 80% of the cost of the stage. Building new tanks for each mission will limit the flight rate, however.
