Navarro Navarro refers to the area where a Poseidon Oil refinery and an Enclave military base are located , northwest of San Francisco , along the far western coastline . Background . Before the War , Navarro served as a Poseidon Oil refinery for the Oil Rig , where the Enclave headquarters is located . Adjacent to the oil installations , a government - funded military base was constructed , together with a satellite up - link station , as well as maintenance and repair facilities . Decades after the Great War , the base was commandeered by the Enclave , who converted it into their primary mainland outpost , establishing a refueling station for their Vertibird s . Due to the relatively short range of the Vertibird , as well as frequent malfunctions , especially in post - War conditions , Vertibird schematics were almost always present on site for necessary repairs and maintenance , but were prone to misplacement . Four were initially ordered , yet by 2241 , three had already gone missing . Some time in Navarro Dr . Henry and Dr . Schreber worked together , but they had different theories about the mutation in the Wasteland population . Henry was arguing with Schreber about the mutation problem once again when Schreber , in a fit of anger , told Henry he was going to recommend that Henry be transferred to another Enclave facility where he would be put to work on cybernetic maintenance . Henry took the threat very seriously , and within hours stole a cybernetic dog and slipped away from the Navarro facility . The Enclave , while not pleased with his attitude and the directions of his research , were not happy with his escape , as they needed all of their available scientists , as a result , several soldiers from Navarro were punished for negligence . In 2241 Navarro is relatively new and not fully staffed as of yet . When the Enclave was preparing to use the FEV , many replacements were coming to Navarro from other smaller installations . Chris is supposed to clear many of the new soldiers . At this time the Chosen One visited the base pretending to be a new recruit , who was sent here to assist in the staffing issue . Drill sergeant once caught him without his uniform . The Chosen One killed Schreber , freed Xarn , repaired K - 9 ' s motivator and took him to the New California Republic . He also stole the Tanker FOB from the base commander ' s locker , and used it to pilot the tanker and destroy the Oil Rig . Sometime after the destruction of the Oil Rig , Autumn Senior led the majority of Enclave forces east . Some years after that , as part of the NCR - Enclave War , Navarro was assaulted by NCR forces in order to remove remnants of the Enclave from NCR territory . The NCR won the battle and the Enclave forces scattered . Navarro was sacked , and the advanced technology left behind by the Enclave was recovered by the NCR , but it was too advanced in origin and makeup for them to understand . However , they noticed that the symbols found upon the technology ( American flag , silo stencils , etc . ) were identical to those that had been recovered at the Divide so a tie between the two was suspected . The NCR hired a Courier to take the item from Navarro to the Divide . Its loss was evidently unknown to the Enclave contingency on the East Coast , as ED - E ' s creator Whitley makes reference to " Navarro scientists " in his audio - logs , under the assumption that they will continue his development of the duraframe model eyebots . One of the " Fallout : New Vegas " endings for ED - E in which its memory is not wiped will show it traveling to Navarro and vanish ; ultimately leaving both its fate , and the current state of Navarro unknown . If you rescue ED - E ' s clone in the Divide and choose to launch Ulysses ' payload , it will continue its quest and eventually reach Navarro , however , it is never stated what the clone found or saw at Navarro . Location . Navarro can be found fifteen squares south of Arroyo . Layout . Navarro is divided into three districts . Gas Station . The station acts as a checkpoint for the Enclave ' s military base , Navarro - the sentry ' s role is to turn away any undesirables and receive replacement recruits from other mainland bases . He is supposed to clear them and direct through the minefield in the forest next to the station . Main Base . The surface houses the Vertibird landing pad , as well as a Vertibird hangar , maintenance workshop , air traffic control station , barracks and the drill sergeant ' s quarters , with adjacent kennels . Underground . The underground areas of the base contain the base ' s armory , mainframe , commander ' s office and the soundproofed science lab , operated by Dr . Schreber , participating in the deathclaw intelligence enhancement project . Appearances . Navarro appears only in " Fallout 2 " and is mentioned in " Fallout 3 " , " " , " Lonesome Road " and " Fallout Bible " . Fallout 3 mention - the Brandice Family , who lived across the street from Bryan Wilks and his pa in Grayditch , moved to Grayditch from Navarro .
