The bunker is sealed by a password that can only be obtained through Arcade Gannon's companion quest, For Auld Lang Syne. The station was placed on standby mode decades ago, and is in good working condition despite the time that has passed. According to Judah Kreger, the bunker is an old Enclave vertibird refueling station. Some members of the Enclave took refuge in the bunker, while others integrated into other towns and settlements.
Sometime after the destruction of the oil rig, the New California Republic sacked Navarro, spreading the Enclave across the wasteland.
