End of Luftwaffe ops in WWII?

This probably does not technically count as being ‘during WW2’ but you might be interested in the Luftwaffe flying boat unit that operated a cargo & passenger service between the UK, Denmark and Norway until late 1945. The RAF used all-German crews, who were given some strange type of status, halfway between POW and civilian. I can get you more details if you wish.

out of sheer curiosity what or when was the Luftwaffe’s last sortie in WWII?

No idea about non-operational…..

But, on the 4th May 1945, Lt.Rudolf Schmitt of JG.1 engaged a RAF Typhoon at low level whilst flying a He 162 jet, which must be close to being one of the last Luftwaffe operational sorties against the Western Allies.

However, two well known Luftwaffe Experten scored air victories on the last day of the war.
The legendary Erich Hartmann scored the last of his 352 victories in the early morning of 8th May over Czechoslovakia.
And at pretty much the same time, Gerd Thyben scored the last of his 157 victories whilst flying his Fw190 east from Courland across the Baltic to surrender to British forces in the west, and this was while having his trusty chief mechanic crammed into the radio compartment behind him!!!

all very interesting replies, have long been curious on this subject as the Luftwaffe wasnt officially dissolved until 1946

The Fa 223 twin Rotor helicopter V14 was flown from Germany to RAF Beaulieu by its German crew in September 1945 and in doing so became the first helicopter to cross the channel.
It was damaged in a heavy landing in October 45 before a british crew had the chance to fly it for evaluation.

A Norwegian-based Arado 234 of 9/KG76 apparently flew a reconnaissance mission over Scotland on May 5 1945.
One wonders why, with the war so obviously lost and the Norwegian units well removed from the fighting in Germany. One final flight on a spring day with nothing better to do? Or did the German forces in Norway seriously believe they could hold out a bit longer for better surrender terms?

[edit: I’ve just found another source that dates the flight a few weeks earlier on April 10. Anyone know better?]

KG200 were still flying in late april/ early may.
