The VLS-1 (Portuguese: Veículo Lançador de Satélites) was the Brazilian Space Agency's main satellite launch vehicle.^[2] The launch vehicle would have been capable of launching satellites into orbit. The launch site was located at the Alcântara Launch Center^[3] due to its proximity to the equator.

Associated vehicles include the Sonda I, Sonda II, Sonda III and Sonda IV, the VS-30, VS-40 and VSB-30.

The VLS was cancelled after decades of development and high expenditures with poor results and a failed association with Ukraine that slowed the program for years.^[4][1]
