The VS-40 (Foguete Suborbital VS-40) is a Brazilian sounding rocket using solid fuel and stabilized aerodynamically.
The original version, VS-40, uses the S-40TM (4,200 kg) first stage engine and the S-44M (810 kg) second stage engine. This configuration corresponds to the upper stages of the VLS-1 rocket.
Version VS-40M used a S-40M engine for the first stage.
