PoD: Mitchell does not issue a statement after the crash of the dirigible Shenandoah in 1925. He is not court martialled as a result, but remains an air power advocate in the US Army. During this period, he also becomes convinced of the benefits of standardizing on a relative few aircraft types due to this making supply and logistics easier.
Franklin D. Roosevelt appoints him as assistant secretary of air(1), and sends him on a tour of Europe, especially Britain. Mitchell's ideas about the obsolesence of naval vessels in the face of air attack are however not taken up at home.
In Britain, with the worsening political situation, and already fearful of a German aerial knock-out blow to London(2) at the start of any new war , his ideas are adopted by the Ramsey MacDonald and subsequent Baldwin governments. The dire economic situation, combined with the fact that hundreds of aircraft can be built for the cost of a single battleship, and the economies that this allows, no doubt plays a part in their calculations.
The Royal Navy is to be scaled back greatly with virtually no new major new units to be built after 1934, and severe cut-backs in personnel, training and supplies (even of fuel and ammo) mean the fleet is in poor condition.
Resources saved from the RN, are devoted to the RAF are poured into aircraft production. The idea of standardizing on a few aircraft types is greatly favoured too.
Masses of Handley Page Heyford aircraft (twinned engine biplane bombers) are produced for the RAF -- and other aircraft manufacturers are order to produce this type too. They are intended to be used to bomb enemy targets, including the ships of any invading force.
From 1939 onwards the Heyfords are supplemented by Armstrong Whitworth Whitleys (twin engine monoplane bombers) and Vickers Wellesleys (monoplane light bombers).(3)
Meanwhile, the RAF fighter arm is equipped with Gloster Gauntlets (biplane fighters with open cockpits), and from 1935 onwards, thanks to their accelerated development, with large numbers of Gloster Gladiators (biplane fighters with closed cockpits).
It is however recognized that the armament of the biplane fighters is inadequate for use against heavy bombers, and so a newer aircraft, preferably a monoplane, with heavy armament is required. The RAF adopts the Boulton Paul Defiant(4) (monoplane with a turret) for this role, and is its third main fighter, and it begins to enter service in large numbers from 1937 - by mid 1940, the RAF has over 1,200 of this aircraft in service, and it has been begun to replace the remaining Gladiators.
When war breaks out in 1939 after the German invasion of Poland, the Chamberlain government is confident of repelling German aerial attacks on the UK, as well as preventing any possibility of German invasion.
The Royal Navy is given three principle goals in the war:
1. To blockade German seaborne supplies
2. To protect convoys to the UK
3. To provide supplies to the BEF
Major surface units are for the most part to remain inactive (the UK being considered adequately protected from invasion, thanks to bomber aircraft), although the best units are deployed to Singapore to deter any Japanese threat(5). Returning First Lord of the Admiralty, Winston Churchill, is disgusted by this treatment of the senior service, and eventually resigns from this position when the war cabinet forbids the navy taking action against iron exports from Norway with comments about "disasterous flanking operations"(6)
In April 1940, the Germans do invade Norway. They are actual able to deploy naval larger forces in support of the campaign than the Royal Navy, despite nominally being vastly outnumbered - simply because of the poor condition and lack of supplies of RN ships. The Germans suffer only 1 destroyer lost, but manage to sink a number of RN vessels, and even capture 3 RN destroyers in Narvik which had been sent to defend the port with inadequate fuel and supplies to escape to the UK. The RAF bombers fail to make any real impact on the course of the campaign - but the RAF insist this was due to unusual and unrepeatable conditions.
In May/June 1940, the Germans over-run the low countries and France. The worst part of the defeat from the British point of view, is the surrender of the entire BEF after is surrounded near Dunkirk. Naval evacuation is considered briefly, but the option is not tried - due to the poor state of the RN, and the assumed vulnerability of all ships to air attack.
Just before the surrender of France, Churchill is recalled to the Admiralty and war cabinet yet again. He orders, without war cabinet authorization, an RN attack on the French navy base of Mers-el-Kebir. The attack does some damage, but most of the French vessels escape to Toulon. A number of French vessels also manage to break out from Alexandria, and head for France too. Churchill is forced to resign from the government, again, and Marshall Petain's government is on the brink of war with Britain.
In July, Britain faces the threat of invasion - its leader weak, its army lost, its navy unseaworthy, and its airforce equipped with poorly chosen and obsolete aircraft. The result was a foregone conclusion...
Footnotes
(1) In OTL, Mitchell did think he might get this position
(2) British governments of the 1930s were fearful this possibility in the 1930s OTL.
(3) Later introduction of these types can be largely attributed to the fact that aircraft manufacturers of this period were encouraged by the government to concentrate on mass production, rather than development, until a specific enquiry for a new aircraft had been issued. This management system, can also be attributed to the relatively small number of new types of aircraft developed and deployed by Britain during the European War of 1939-1940.
(4) Popularly known to its pilots as "Daffy"
(5) Ironically, many of these vessels were sank by the Japanese aircraft in 1941, belatedly proving Mitchell's theory correct.
