Are there any US States with no non-National Guard military bases?
Minnesota is one. New Hampshire has Portsmouth Shipyard but I believe it’s falls within the borders of Maine.
In case you didn’t notice, the three states missing are IA, MN, and VT.
(It took me ages to figure out that VT was missing from the list in the link!)
I would say that New Hampshire counts too. The shipyard is on the border with Maine and New Hampshire and is named after the nearest city in New Hampshire but it’s located in Maine. It’s physical location is an island next to Kittery Maine.
I was just going off the list in @Saint_Cad’s link.
Me too. I clicked on a few that sounded like they might not fit.
Indiana is pretty sparse. Camp Attabury is a National Guard post. Then they have a AF Reserve base. I was unaware of NSWC Crane. Reading up on it I see that it definitely qualifies as an active duty post. Reading up on its mission I suspect it has a ton of civilian employees working on various systems but it’s still an active duty post.
I didn’t even look at it. I saw it answered the OP’s question and offer it as a resource for them to do the research.
New Hampshire has the New Boston Space Force Station(formerly the New Boston Air Force Station).
You say no Guard bases, but what about Reserves? Those don’t appear in Saint Cad’s link. There’s an ARS in Minneapolis, for example. Not sure about IA or VT. There’s also a distinction between a station and a base but I’m not sure if that’s important to you.
The map linked-to above doesn’t work for me. However, I’m sure there are no active duty bases in Oregon.
I don’t know how you define “base.” There is a Coast Guard air station at North Bend and the Navy has a bombing range near Boardman (Naval Weapons Systems Training Facility Boardman - Wikipedia) with a permanent staff of six people.
It’s also how you define “military”. The Coast Guard operates under the Dept of Homeland Security in peacetime, which this is, and not the Dept of Defense. So if “military” is restricted to DoD people, it doesn’t count.
As for the bombing range, I knew about it but didn’t know there was anyone assigned to it who actually worked in Oregon.
The bombing range in Boardman, OR is actually part of NAS Whidbey Island in Washington. While I was stationed at Whidbey, folks (both military and civilian) from my assigned shop would fly down to Boardman every 60 days or so to perform maintenance on the equipment there. The squadrons would send there own people down when practicing bombing runs. The civilians that worked at Boardman were actually from the nearby Umatilla Depot. The Wiki page says it still part of NAS Whidbey.
The Umatilla Depot has been transfered to the state of Oregon. So obviously that’s changed the status of anyone working out of there.
I’ve had some professional contact with the Naval Surface Warfare Center - Crane and, being familiar with Indiana’s coastal geography, was first a bit incredulous that any Navy research was really happening there. Pork barrel military spending, right? Nope, it’s the real deal with science and everything.
I’m assuming It’s along the lines of Lakehurst NAS with a different focus. Lakehurst is an active duty base (actually part of a Joint Base now) but there is a heavy emphasis on research and development. Much of that is performed by civilians. A family member has worked there for years. Although eventually they answer to a Navy captain everyone else they work with is civilian.
Duluth Minnesota has a Coast Guard Station. They do water rescues, run an ice breaker, handle international vessels that are docking at the Duluth/Superior port, etc. Probably not what must people would think of a military base, since there is no on-base housing.

Duluth Minnesota has a Coast Guard Station.
I’ve already pointed out that the Coast Guard is not part of the DoD, so probably doesn’t count as a military base. We’ll let the OP decide if he wants to count them.
I’ll also note that West Virigina only has two CG bases according to the website @Saint_Cad posted above. So it’s another state with no military bases.
Note that the info on that map is not up-to-date. I asked it for Oregon bases and it only listed the Umatilla Depot and claimed that chemical weapons were stored there. (The chemical weapons were all destroyed over 10 years ago and, as I said above, the Depot has been transfered to the state for other purposes.) It did not list the CG Station at North Bend nor did it have the CG Station in Duluth.
There is a Navy Reserve Center in every state. There are also recruiting centers in every state.
So I guess it comes down to how you define ‘base.’
