S-4 / Papoose Lake (alleged facility).
allegedgovernment_studyLazar / S-4 / Exotic Tech
Alleged secret subsidiary base near Papoose Lake, ~S of Groom Lake, where Lazar claims he reverse-engineered alien craft. No credible evidence it exists; real 'S-4' is at Tonopah.
Per Lazar, S-4 sits near Papoose Lake just south of Area 51, with camouflaged mountainside hangars holding nine flying saucers and security tighter than Area 51 itself. Never officially acknowledged. Researchers note the documented 'S-4'/'Site 4' is a Tonopah Test Range radar facility ~70 mi NW of Groom Lake, not south of it, and no facility has ever been credibly shown to exist at Papoose Lake.
