Avio’s Space Propulsion Test Facility at Perdasdefogu, Sardinia, is a private industrial rocket-engine test site in the Salto di Quirra range. Avio’s official facility release describes a liquid-rocket-engine test bench for development and qualification of cryogenic liquid-oxygen/liquid-methane engines and a subsequent carbon-carbon component production phase. The current Avio site listing names the Perdasdefogu facility, and an independent mapped footprint is named Space Propulsion Test Facility di Perdasdefogu and tagged as an Avio rocket-engine test area. This is a fenced industrial and range site; the reviewed sources do not establish general visitor access, so contact Avio and the relevant range authority before planning a visit.
