It was previously operated by the military until 1994. They now operate largely in tandem with other nations. They run a spaceport and rocket launch site both in Brazil. They built the VLM small satellite launch system in tandem with Germany. The VLS-1 was intended to be a primary launch vehicle for the BSA, but it failed 3 times and was canceled. They have restarted work on the system in tandem with the Russian Space Agency.",
