Hyperdyne Systems 120-A2

The USCSS Nostromo Science Officer Ash, (ID 111/C2/01X), was activated in 2118 and placed aboard on Thedus in 2121 for the return trip to Earth.  Mother, I-2037, recorded a weak signal on route to Thedus and the Nostromo's course was updated in Interface 2037 (Weyland-Yutani Report, page 69). 

​

The first Hyperdyne Systems series were constructed by the Weyland Corporation based on designs from the late Sir Peter Weyland's notes (Weyland-Yutani Report, page 35).
