NonCredibleDefense

Too credible

Until you realize that interference with the "timeline" means many of the battles never happen, new tactics can be countered, and modern logistics require strong communications - you have info on the wrong war.

A boomer with non-gps ICMS would literally make a world of difference. Hell, transporting a modern university and all its research, staff and equipment could make a world of difference. Include climate change results.

I don't think modern Rangers hold significant advantage over WWII rangers. I think they would actually be a detriment, as the WWII rangers were familiar with the technologies available in that time period. Those modern rangers do carry more radios than the entire invading force had during D-Day. But, any base you send will have plenty of radios to issue.

My first thought was Norfolk. They've got enough ASW assets to stop the U-boats that were decimating the convoys. Yeah, they won't be able to rearm modern weapons or repair/replace certain damaged systems, but with the U-boats out of the way, the original fleet would have been much more successful. Even after the modern weapons are exhausted, the C3/ISR capabilities of the future fleet will greatly enhance the operations of the past.

My second thought is Wright Patterson AFB, home of the US Air Force museum. Designers get to tear apart aircraft that wouldn't be built until after the war, but not so advanced that they exceed the past nation's ability to produce. They get turbine engines 4 years early, and figure out all the transonic effects thet kept them from breaking the sound barrier. Turboprop-powered heavy bombers, flying higher and faster than anything the Axis can throw at them. Turboshaft powered submarines, destroyers, PT boats, helicopters, tanks

Third thought is to skip straight to the endgame and try to accelerate the Manhattan project. It might be a bit of a stretch to call it a "military base", (and it's not on the list above) but we could send them the Savannah River site. They get more plutonium than they know what to do with. With enough plutonium, they can afford to drop demonstration bombs in unpopulated areas of both the Asian and European theaters, possibly without needing to bomb Hiroshima or Nagasaki. We can avoid the need to invade both Japan and Germany.

Any base we send would have modern computers and some programmers. The German Enigma code could be brute-forced in a matter of hours on a modern computer. That alone is going to shorten the war in Europe by months to years.

Blinkov's Battlegrounds did a detailed thought experiment: what happens if a single F-15 is transported to 1941 Pearl Harbor. What could it do?

He also did a thought experiment along similar lines in a different video, if an entire modern supercarrier was transported back to WWII. Both videos are some of my favorites.

They could, for a little while. You'd have a very hard time refining petroleum fuel in 1942 to the quality necessary for the jets, so you'd be limited by however much was stored on the base.

I'm also not sure how you'd deploy those aircraft across the Pacific or Atlantic other than disassembling, shipping and then reassembling them.

just because Russians, Moscow.

Leningrad looked at me funny, I swear.

Moscow

Just nuke Moscow, and send a message to the Germans and Japanese to surrender, or they'll be next.

Boomers and SSGNs are stationed at either Kings Bay, GA or Naval Base Kitsap in Washington.

Why attack Russia? Aren't they our friends now?

I like your style.

The engine in the Abrams is actually a "multi-fuel" engine. It's probably cleanest and most efficient on jet fuel, but it can run on marine diesel which is basically trash fuel.

Jet fuel is basically kerosene, which was invented in 1846 and available from refineries long before diesel (1894) and gasoline (1892). Refineries were producing fuel that jets could burn long before jets existed. Most military aircraft can burn diesel or ordinary kerosene if jet fuel isnt available, they just need to be careful to avoid gelling, which can occur in the cold air at high altitude.

GPS is needed for a certain degree of precision in standoff weapons. Without it, they have to rely on laser or TV guidance, or dead reckoning. The ring laser gyros and accelerometers they use in their inertial guidance systems are far more accurate than the guidance systems used aboard V1 and V2 rockets, which were themselves surprisingly effective.

GPS is not required for navigation of manned aircraft: they can rely on terrestrial radio beacons or dead reckoning with their own inertial navigation systems.

I can't think of a weapons system that actually requires Internet access.

I had to look up castras and now, I must subscribe to your newsletter.

Now known as Cavazos. The country decided to maybe not name bases after traitorous losers.
