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.
Flights VS40 performed the following flights:
A flight of VS-40M carrying "SARA Suborbital 2" was planned but eventually cancelled. A future flight of VS-40M carrying HIFiRE 8 is in development.

S-40 rocket engine The S-40 is a solid-propellant rocket motor developed and manufactured by Avibras Aeroespacial, a Brazilian aerospace company, primarily for use in sounding rockets. Different versions were used on several rockets:
S-40 - first stage of Sonda IV S-40TM - first stage of VS-40; third stage of VLS-1 S-40M - first stage of VS-40M; second stage of VLM
