The VLM (Veículo Lançador de Microsatélites) is a proposed three-stage satellite launcher being developed by the Brazilian General Command for Aerospace Technology in collaboration with Germany. The project originated in 2008 as a simplified version of the VLS-1 rocket, using only the core stages. The first launch is currently planned for no earlier than October 2028

A version based on the S-50 rocket motor is being developed, with the objective of launching satellites of up to 150 kg into equatorial circular orbits at 300 km altitude.
