alternate history

I'm considering Kaiserreich-esque Alt Hist timeline where Canada + a bunch of British exile engineers have to build aero engines -- for speed of development, reliability, and simplicity they just develop the Bristol Mercury/Pegasus, avoid sleeve valves and stick with poppet valves, and also go...

Hi everyone, We have already discussed a shorter/no Vietnam scenario already so I will not ask for changes related to this. However, what I was wondering about is whether having a second JFK term (due to no assassination) instead of a Johnson term would affect 1963-1968 procurement in any way...

Now that TSR2 has been the subject of a conference of current experts on the subject, I am asking the BIG question. Could TSR2 have been made to work? By which I mean could it have been designed and developed in such a way as to let the RAF take delivery of say 50 machines by 1970? All...

What happens if the Bristol T.188 research aircraft doesn't underperform? What happens if it flies upto Mach 2.8 and reaches the thermal limit of the windscreen? We now know that it's underperformance is related to lack of interest and investment in the Gyron Junior engines after the...

When I was surfing the Internet, I saw a post on the World of Warship Forum(https://forum.worldofwarships.eu/topic/3095-what-if-the-war-began-in-1944-royal-navy-battleships/) that an article assuming World War II would have broken out in 1944. And after reading that, I wondered what would...

The major disadvantage of the MIM-72 Chaparral (initially) was its inability to engage jet aircraft head-on. The AIM-9D "Sidewinder", on which its missiles were based, could not lock on target from this aspect. While it wasn't a major disadvantage for a AAM, it was a big hindrance for SAM, since...

Starting point Juan de la Cierva had already decided to continue his work motorizing the gyroplane's rotor. He misses his flight at Croydon which crashes in December 1936 because his car has a flat tire. He travels on the next flight, meets with Focke, and together they design and develop two...

Good sf doesn't just introduce new concepts, it explores the ramifications of those concepts. As HG Wells introduced tanks, DEWs, nukes, transnational organisations, and air power, he also explored what they would mean. Now, I really can't recommend : Lem enough. Under this topic, his 1964...

While I was reading about a report abou Sinking of Prince of Wales and Repulse, I suddenly wondered what history would have been like if HMS Indomitable had been assigned to the Force Z without any damage, or if the Implacable Class Aircraft Carrier had been built earlier than the original...

This was idea I had reading the merage IV threads, the idea being the the lockheed bribery scandal breaks in Germany befor the deal goes though leading to anything American becoming politically toxic, this leads to Germany (and though them the rest of the nato f-104 block) to buy the Mirage III...

I got this idea from some discussions I've had elsewhere and something that was brought up in a thread about making a "Spitfire into a baby Tempest". I sort of don't think that the Spitfire IX as built would be 100% suitable for what was mentioned in that thread for a "multi-role" fighter...

Lets send the MiG company on the path not chosen wrt. their 'budget' fighters. Instead, they make a spin-off of the MiG 19 that has a wing better suited for high speeds (not 8.74% t-t-c at root as on the -19, but under 4.5% as it was case with MiG-21; wing is also of the shorter span), and...

On a very topical note, a horror game that, appropriately enough, has recently returned from the dead. Not to be confused with the 2020 game of the same name. https://www.pcgamer.com/sorry-routine-is-back/ https://kotaku.com/routine-raw-fury-indie-horror-space-alien-isolation-pc-1849043193...

Model posted by Bob Gibson in What if and alternate history Facebook Group it's a speculative model reconstruction of fictional hydro version of Mosquito.

These are well worth a look. I wonder what FIXEDIT could do with a bigger budget! View: https://youtu.be/VVjdFBZCRQc View: https://youtu.be/zo8FhChnyq0 View: https://youtu.be/rTov2oSXR8M View: https://youtu.be/4irbMNQc8As

Many Tu-22M squadron fire cruise missile raid on enemy target and Japanese SHINKANSEN devastation screen shot from Japanese animation ″Future War 198X″. This post added Japanese SHINKANSEN devastation screen shots.

What if Messerschmitt 210 was produced based on V1 ? (Without any thousand modifications that made Me 210 a failure). I suppose that, probably an hypothetical Me-210A ( based on V1) could have been more success than real history of Me 210.

So what the title says. Say that cme the armistice in 1943 the Italians are able to tow away the ship to some secure port. Or alternatively if you want things simpler Italian commandos do not scuttle the ship in April 1945 and the Germans fail to sink her on their retreat. Either way you have...

The saga of HMS Hermes is well known. But it might have been different if the RN had followed the US example and kept her as an ASW carrier or interim Sea Control Ship. The US were introducing the S3 Viking on to their attack carriers but were keen to get as many to sea as possible. HMS Hermes...
