POD 1 : HMS Triton sinks the cruiser Blucher on 8 April 1940 with a successful torpedo strike. On 9 April 1940, Norwegian coastal fortresses at Oslo sink Lutzow (instead of Blucher, now on the ocean floor) and the cruiser Emden is also sunk by the Oslo fortresses. The German invasion force bound for Oslo is sunk at sea and attempts to land troops by air to capture Oslo fail.

POD 2: On 8 April 1940, HMS Renown and its escorting destroyers sink the German cruiser Admiral Hipper and its destroyer taskforce in exchange for losing HMS Glowworm, preventing the German invasion of Trondheim. Interrogation of the German survivors results in the Home Fleet heading straight for Narvik. The Home Fleet sinks Scharnhorst and Gneisenau on 9 April 1940 in exchange for losing HMS Renown and HMS Repulse. Over the next few days (until 14 April 1940), 4 British destroyers are sunk in exchange for sinking all German destroyers at Narvik.
POD 3: British cruisers carrying out Operation R4 sink the entire German invasion force bound for Bergen in Bergen and successfully land troops who assist the Norwegians in defeating and capturing the German invaders in Bergen. The cruisers Konigsberg and Koln are sunk with the training ship Bremse at Bergen. Cruiser Karlsruhe captures Kristiansand only to be torpedoed and sunk by HMS Truant outside of Kristiansand.
POD 4: Due to earlier Norwegian mobilisation, the Egersund invasion force is sunk by Norwegian torpedo boat Skarv and the invasion force's survivors reach Kristiansand instead. Sola airbase, Egersund and Stavanger stay in Norwegian hands. On 18 April 1940, HMS Sterlet sinks German training ship Brummer off Kristiansand before Sterlet is sunk by depth charges. Kristiansand and Narvik will be the only Norwegian ports controlled by German hands on 20 April 1940. In addition, all German supply ships sunk in the otl Norwegian Campaign in April 1940 will be permanently sunk in this Norwegian Campaign, along with the merchant ships Rio de Janerio as in otl, Rauenfels (as in otl), Roda (as in otl), Main (as in otl), Sao Paulo (as in otl), Levante (scuttled off Trondheim to prevent capture) and Barenfels (sunk in Bergen) permanently sunk by April 1940. All German tankers sunk in the otl Norwegian Campaign would be permanently sunk in this timeline.
POD 5: Naval victories off the Norwegian coast result in more decisive action taken against the Germans at Narvik, resulting in their surrender before June 1940 along with the Allied recapture of Narvik. The same occurs with all other German controlled Norwegian ports, resulting in the German invasion of Norway failing completely by 21 May 1940.
To make things worse, all German Type IIA submarines have been sunk in the campaign (U-1 by mining before the pod on 6 April 1940, U-2 as the first WW2 u-boat sunk by aircraft excluding the salvaged U-31 on 10 April 1940, U-3 sunk one sided by HMS Porpoise on 16 April 1940, U-4 sunk one sided by HMS Thistle on 9 April 1940, U-5 and the Q ship Steinbek sunk one sided by a surviving HMS Tarpon on 10 April 1940 and U-6 sunk one sided by HMS Sunfish on 12 April 1940).

July 1941: Despite the heavy paratroop losses of a German pyrrhic victory at Crete, a second failed invasion of Norway shortly after the start of Barbarossa (which fails as in otl) costs the Kriegsmarine the Graf Zeppelin, the Bismarck, 2 pre dreadnoughts, the Prinz Eugen, the Admiral Scheer (plus Lutzow in April 1940 as mentioned above and Graf Spee before the 1st pod), both Leipzig class cruisers and 10 destroyers. In exchange, the Royal Navy loses HMS Glorious, HMS Hood, 3 cruisers and 8 destroyers. The sea threat to Norway has been ended by the moment. The remaining purpose built Kriegsmarine ships of cruiser size and larger will stay in Germany until their complete destruction at the Battle of the North Sea while attempting to destroy Arctic Convoy JW 58 in April 1944 and over the Normandy landings. Another German cruiser named Lutzow will be sold to the Soviets and remain incomplete but afloat at Leningrad postwar.
WW2 goes roughly as otl (at most, prolonged by only three months to evacuate German troops from Scandinavia and a Baltic pocket or two, latter as in otl) or is sped up by a few weeks (German iron ore and heavy ship shortages, the increased German need to defend the German and Danish North Sea coasts and the German need to defend Axis Finland's borders with Norway and Sweden plus the amphibious and paratroop losses being balanced by fewer German troops in Norway excluding some of these troops being lost at sea; with the Axis Power composition same as otl but with Norway not invaded successfully by Germany).
