It looks like there is a really big gun on the back of this aircraft.

    $\begingroup$ The "big gun" is a rocket engine. $\endgroup$

    $\begingroup$ @Simon, it definitely is not a rocket engine; this engine is air-breathing (pulse jet). $\endgroup$

  • $\begingroup$ Looking at the better quality picture in ymb1's answer, it looks more like a scope to me... $\endgroup$

  • $\begingroup$ @JanHudec Cough, cough, er, that's what I meant. ;) Was thinking of V2, which of course looks nothing like this. I'll get my coat. $\endgroup$

    $\begingroup$ Now, if you want an aircraft with a big gun, I suggest the Hs-129 B-3 $\endgroup$ Commented Feb 11, 2017 at 22:36

1 Answer 1


That's a German WWII V-1 flying bomb.

It was an early cruise missile and the first production aircraft to use a pulsejet for power.

The pulsejet being the tube on top.

    $\begingroup$ The Germans used to launch these across the English Channel and the brits would defend against them by shooting them down with spitfires. $\endgroup$

    $\begingroup$ Or by tipping them over with wing-to-wing near contact! Thanks, ymb1, I've spent the last 3 hours reading up on the V-1, V-2 and various other German inventions. It was a nice way to pass a Friday afternoon... $\endgroup$

  • $\begingroup$ @FreeMan And by AA guns controlled by trajectory-predicting control systems. Check out this lecture Between Human And Machine: Feedback, Control and Computing Before Cybernetics at 00:43 $\endgroup$ Commented May 26, 2017 at 22:53
