The bunker is sealed by a password that can only be obtained through Arcade Gannon's companion quest, For Auld Lang Syne. 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 Control station Enclave, the New California Republic sacked Navarro, spreading the Enclave across the wasteland.
