VS-40

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.
