ARCA kept work on the project secret and decided to reveal it to the public in a press conference that took place at BRD headquarters in Bucharest in December 2010.

Another factor that went into the decision was the fact that Romania has no unpopulated areas above which to safely test the aircraft to high altitude flights.

The aircraft has diamond-shaped wings to reduce weight, and lower drag at high speeds; "V" tails were chosen to avoid contact with the water on take-off and landing.

The aircraft will be powered by the new Executor liquid-fuelled rocket engine, under construction at ARCA, which will use kerosene as fuel and liquid oxygen as oxidizer.
