NonCredibleDefense
A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

The reason for those was that the bombers were vulnerable to fighters approaching from below. I don't think that this'll be applicable for a number of reasons:
No reason to use a large aircraft like that. All they need is a plane that can get altitude and hold two people.
My guess is that one issue for the B-17 in WW2 was that they needed to fly in formation, couldn't maneuver much, to achieve the "interlocked fields of fire" that was their defensive doctrine of the time. So becomes harder to deal with a blind spot by maneuvering, so there's a need for exotic things like the ball turret.
The drones that they're shooting down are defenseless. If Russia does start sending out drones with some kind of air-to-air capability, my guess is that a ball turret won't be a good counter.
I'm pretty sure that those ball turrets used .50 cal machine guns. They probably don't need that. My understanding is that the round caliber in WW2 that a fighter carried depended on what they expected to run into. It was a the reason that the US only used .50 cal machine guns, not 20mm autocannons, in its fighters -- the 20mm was only considered necessary to bring down a bomber, where the thing was a big structure, big struts, could potentially absorb a lot of damage. The US wasn't fighting anyone who was going to be using much by way of heavy bombers against them. I suspect that the lightest of bullets will probably mess those little drones up badly. Honestly, they'd probably do best with a shotgun or automatic shotgun at the very short ranges that I've seen footage of them engaging at; that's more likely to expend kinetic energy inside the drone, hit a lot of stuff in there. Also reduces collateral damage to whatever is off in the distance behind the drone.
