FW-190 strafing ground targets in January 1th 1945, not sure what type is the twin engine parked, looks like a B-25.

Luftwaffe fighters vs bombers, 1944, some clips are alredy posted, but note the last one wich includes a pursuit of damaged B-24 liberator at low altitude, the Liberator turrets blazing with gunfire, very action charged.

I could swear one part of the film showed A-20s in New Guinea with para-frags. Don’t know how that got into the film.

I ve seen already allied footage inserted in german wochenschau ( in particular footage of damaged b-17 landing in UK) , so there were some channel for the germans to obtain those in ww2.
You probably are suspicious about the minute 2:15 when a few bombs are seen dropped at low altitude, no way that a fighter could had filmed that.
Better quality upload of this video, by the way the devil head bagde belonged to the 9th staffel in JG 54 not JG 1 as said before.
Me-110G attacking bombers, several types and configurations with droptanks, aditional 20, 30 and 37mm guns are seen.
Extracted from the Deutsche Wochenschau 705, march 1944.
YouTube - Zerstörer in Einsatz. Messerschmitt Me-110G Vs Amerikanische bomberverbande
Long guncame series, showing all the aspects of bomber interceptation and some speech by walther Oesau comenting the “hunt” of that day…
Me-109 vs P-40 tomahawks and kittyhawk, the german pilot fires at extreme close range in the last frames.
As if the Stuka wasn’t already a formidable foe, someone adds a bigger guns!

It was, however the 37mm loaded stuka was a bit slower thst the usual Ju-87d in clean configuration.

Okay, first re-upload, this is an late 1943 footage ( DW 689 ) fighter against bombers, the bagde seen is of the 9 staffel /JG 54.
the first section is Walter Dahl the CO of JG 300 driving up and congratulating the pilots of IV.Sturm/JG 3 after they shot the US 492nd bg to shreads this on 7-7-44. the only other possible section is the close-in details of the three differnt Fw 190A-8 attacks showing from the rear end with the funny gun-sight in the middle of the frames. I have analized these guns still for many eyars and have not yet come up with the gruppe/Staffel attacking but they are using well known Sturm like tactics to close in as much as possible and then bank off to avoid ramming and the flying debris of US craft.
