Naval Base Guam

Naval Base Guam at a glance

Naval Base Guam supplies the Pacific Fleet with logistics, operational support and maintenance services. Its public mission combines facilities and a dedicated workforce with support for personnel and families, making the base both a naval activity and an overseas military community. Its harbor setting and shore services sustain forces operating in the Pacific.

The base's history is connected to Apra Harbor and the rebuilding of Guam after the Second World War. Navy construction developed supply, ship repair and submarine support facilities as part of that expansion. Today the installation is part of Joint Region Marianas, which coordinates support policies and resources while the separate base commands retain their mission responsibilities. This distinction helps explain how Guam's naval, aviation and Marine communities work together.

Before you arrive

Use these questions with your sponsor or gaining organization. They are a starting point for planning, including assignments, courses and training periods that differ from a routine permanent change of station.

1. Confirm the organization, duration and reporting instructions shown on your orders. Ask which office handles your arrival.
2. Clarify lodging and housing arrangements before booking. Ask about availability, required approvals and how to handle a late arrival.
3. For an overseas assignment, ask your sponsor about family travel authorization, required documents, medical screening, pets and vehicle shipment before making reservations.
4. Coordinate household goods and personal travel with the appropriate transportation office. Keep orders, receipts and important family records together.
5. Make a short list of contacts for medical care, schools, childcare and family support, where applicable to your assignment.
