Vega-C is a single-body rocket nearly 35 m high with that weighs 210 tonnes on the launch pad. As with Vega, its main elements are three solid-propellant stages, an upper stage powered by a reignitable liquid-propellant engine and a payload fairing. Vega-C's P120C first stage replaces Vega’s smaller P80 to provide a significant increase in thrust at liftoff. It is also used as boosters (2 or 4) for the Ariane 6 rocket.
