"Herr Alvarez, it is good to hear that the new Silent Running systems are working perfectly, remember comrade that it is not a true cloaking device, but a specially designed system that automatically shuts down everything non-essential and puts all other systems into a power-saving mode, it'll keep you alive, however you cannot do much else.
Be warned Comrade, even though your ship may appear as background radiation that is prevalent in Sirius it is no substitute for a Cloaking Device, if they get close enough to see you out a window they will find you comrade.
Still once you've returned please forward a report to our Nachtsonne Lab immediately following a full testing of the systems."
