The Rube Goldberg monstrosity you're looking at above is a result of Stalin's Zveno project, which consisted of repurposing super-colossal Russian bombers like the Tupolev TB-3 to carry up to six Polikarpov I-16 fighter-bombers like winged parasites. Although, "parasites" is probably an unfair description -- in reality this was more of a symbiotic relationship, because once the full crop of fighters was firmly attached, each plane in this flying Jenga tower had to gun its engines just to get the whole ludicrous mess off the ground.
But It Totally Worked!
The idea was that the giant bomber could get the smaller fighters to a target that would normally be out of their range, and to that extent a Zveno could knock non-Russians on their asses more efficiently than a Russian breakfast. (Vodka. A Russian breakfast is vodka.) Once in range, the fighters detached like over-plump ticks to decimate their targets, usually Axis oil depots in Romania, German-held bridges, or anything that smelled a bit too strongly of capitalism. After transforming their target into a smoking crater, the fighter pilots could either attempt to reattach to the bomber in-flight (if they'd had a big enough Russian breakfast) or land at a nearby airfield and prepare to Voltron up again the next day.
The next time you're tempted to bitch about having to parallel park, remember this photo.
While both the TB-3 and the Polikarpov were retired in 1942, by that time Zveno carriers had conducted 30 highly successful raids on the Eastern Front, thereby proving that causing your enemies to point and laugh at you makes it way easier to pelt them with bombs.
