There are 8 regular active-duty Navy SEAL Teams in the U.S. Navy (Teams 1, 2, 3, 4, 5, 7, 8, and 10), plus several closely related special and reserve units often included in broader counts.

Quick Scoop

How many SEAL Teams are there, really?

When most people ask “how many SEAL Teams are there” , they usually mean the standard, numbered operational teams. The clearest, up-to-date public info points to this structure.

Core active-duty SEAL Teams

  • 8 conventional active-duty SEAL Teams:
    • West Coast: SEAL Teams 1, 3, 5, 7 (Coronado, California).
* East Coast: SEAL Teams 2, 4, 8, 10 (Virginia Beach, Virginia).
  • These are the “classic” SEAL Teams people are referring to in most articles, documentaries, and forum discussions.

Other units people count (or ignore)

Beyond those 8, there are additional units that complicate the simple answer “8 teams”:

  • Naval Special Warfare Development Group (DEVGRU), commonly known as “SEAL Team Six”:
    • A Tier 1 special mission unit, separate from the regular numbered teams.
  • 2 Reserve SEAL Teams:
    • SEAL Team 17 (Coronado, CA).
* SEAL Team 18 (Virginia Beach, VA).
  • 2 SEAL Delivery Vehicle (SDV) Teams:
    • SDV Team 1 (Hawaii).
* SDV Team 2 (Virginia Beach).

Some modern overviews describe this picture as: 8 conventional SEAL Teams, 2 reserve teams, DEVGRU, and 2 SDV Teams forming the broader Naval Special Warfare SEAL structure.

Why answers online differ

You will see different numbers depending on how the author defines “SEAL Team”:

  • “8 SEAL Teams” → counting only the conventional active-duty teams.
  • “10 teams” → sometimes meaning 8 conventional plus 2 reserve teams.
  • Mentions of “SEAL Team Six” → usually referring to DEVGRU, which is not a standard numbered team anymore but is still widely known by that nickname.

In short (today’s common framing)

  • If you’re asking in a simple, quiz-style way:
    • There are 8 primary active-duty Navy SEAL Teams.
  • If you include the wider SEAL ecosystem:
    • 8 conventional teams (1, 2, 3, 4, 5, 7, 8, 10)
    • 2 reserve teams (17, 18)
    • DEVGRU/“SEAL Team Six”
    • 2 SDV teams (1 and 2)
      all together form the modern SEAL team structure described in recent public sources.
