alternate history

In this scenario the Vietnam War follows the same path as the Korean war, and after years of intense fighting the two sides agree to a long term cease fire (but no peace deal, like the Koreas). splitting the two countries along the 17th parallel How would this change - the aircraft composition...

So in the same vein as others....what if Sweden turned more of it's projects into reality and which would they be? The big one has to be a Swedish Nuclear Weapons program... Presumably with A36 Strike Aircraft. Would this have a ballistic missile companion? Such Nuclear production could make...

One of the designs for the Tomcat replaced the swing wings with a fixed wing. Such as the 303F What if, in this alternate history.. Grumman decided to go with a fixed wing instead of a swing wing. Then the question becomes How would its performance characteristics be like with a fixed wing...

West Germany in our timeline has since 1951 been a constant pillar in the Western Alliance and a key partner or customer for modern weapons and other secret projects. What if things had been different and other forms had occured. German unification along Austrian or Finnish lines as a member...

I am looking for some "professional" advice on an alternate history scenario that has been running around my mind for years: Given the political will to do something immediately about Hitler's 1 Sept 1939 invasion of Poland, did the British and French military have the resources and the assets...

Boeing and Lockheed beat out McDs, GD, and some other companies to become the two finalists for JSF. Boeing went with a somewhat more conventional engine arrangement, but an unconventional shape Lockheed was opposite and chose a more novel engine arrangement, but had a shape more similar to the...

As the Tartar-derived Standard family continues to thrive https://www.secretprojects.co.uk/threads/standard-missile-projects.7671/unread I am going to re-visit another Hobbyhorse of mine. The Dutch took close look at CF299/Seadart and dropped it in favour of Tartar/Standard for its two Tromp...

The subject which perhaps has been kicked around on this website more than any other is whether the UK could have designed and built a two seater fighter-bomber in the 1960s to replace RAF Lightnings and RN Sea Vixens and replace RAF Hunters (The RN already had Buccaneer). The Hawker P1154 was...

As said in the tin. When you think about it, it would avoid an immense amount of suffering and money waste. Kind of - screw the Tigers - screw CVA-01 - screw Spey Phantoms do we agree all three above were expensive boondoggles ? so good riddance (sorry, that's the radical in me... !) Also...

the Falklands war occurred in 82 Ark Royal (or another ship of the same class?) was decommissioned in 79 What if they had opted to delay the decommissioning by a few years but then the Falkland war occurred anyways Would the Ark Royal have been sent? would it have contributed differently than...

As said in the tin. I've worked on this huge thing since February 2008 when I joined, first, NASAspaceflight.com and AH.com. Took me a decade and 2019 to get a stronger focus and backstory. Now the POD is clearer. In August 1967 at a crucial juncture in NASA history the last Lunar Orbiter...

This concept is from my AH project "Savioe Cross". In short - in 1943, Mussolini was a bit quicker, and managed to broker peace with Allies before the Victor Emmanuel III. Italy managed to came out of Axis more orderly, and successfully repel (with Allied help, of course), German invasion. But...

How useful would it have been if the Royal Navy had grasped the nettle in 1947 and decided to scrap its battleships? Admittedly this is much easier with the benefit of hindsight. But the lessons of the war and the success of air and submarine attacks on battleships were already well known. The...

If the Vickers Valiants had been transfered from strike to tankers earlier could the fatigue problems have been avoided. Their strike role could have been taken on by Vulcan or Victor B1s. With the Valiants serving into the 1970s the Victors could have continued in the recce and conventional...

Given that WWI had a fairly random trigger, it is not particularly strange (in alt history terms) to explore the alternative. So WWI does not happen, while a steady stream of bush wars still does. What happens to military technology? When will the following things be invented and adapted...

Before Polaris was put out to sea, submarines weren't their only host platform; the USN had their Long Beach and Albany cruisers "fitted for, but not with" with eight Polaris tubes. Also, the Italian Navy and their Cruisers held provisions for Polaris tubes. Still, these plans were dashed after...

I need your Advice I working on Story were German history goes little different Here goes Aerospace industry in VTOL with Do-31 and EWR VJ 101 get into service. One of civilian application is a VTOL Business Jet I took the MBB HFB 320 Jet as template With Mass 9600 kg it need around...

After the Cuban missile crisis in 1962 the US replaced its land based medium range ballistic missiles in Europe. While the Minuteman ICBM was the main national deterrent system, the role of countering Russian missiles aimed at Western Europe was taken on by Polaris (later Poseidon) submarines...

In an alternate world where the USA avoided the trauma of Vietnam and LBJ won a second term the Apollo moon and earth orbit programmes continued into the 70s as originally planned. Assuming that a similarly pro Apollo President had succeeded Johnson in 1973 and the US economy continued to...

How could you get Turkey and/or Iran/Persia as a major industrial military power for World War 2? I am picturing one or both as the main antagonists in the 1930's or 1940's with a large, powerful and modern military. Could countries like Italy, France, Poland, Britain and America invest in...
