A community for your defence shitposting needs

Rules

1. Be niceDo 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.

If I remember correctly, it's not really a prototype of the P90, but rather a "workshop model" or something like that (I don't remember the gunsmith terminology). It's not meant to resemble the final product in any way, or even be a usable weapon. Its sole purpose is to test that the internal mechanisms work. Basically, it's the firearm equivalent of the Northrop Tacit Blue.

Either that, or it's the army variant of the Bosch vacuum we had in the kitchen when I was a kid.

If you're interested in more, Lazerpig recent "stealth" video discuses this very aircraft and how it competed with the F-117

Thanks. I am more into prop planes, but knowledge is always good to have.

Gun breadboard.

i truly do not understand just exactly what the hap is fuckening here

[–] FireTower 21 points 9 months ago (1 children)

My best guess is a proof of concept of the idea of rotating bullets 90° for their desired mag geometry.

Here's the final version of the concept.

That seems a lot more likely to jam when you absolutely need it to fire.

[–] [email protected] 4 points 9 months ago (1 children)

Yes but SG1's after action reports indicate this isn't a problem, at least against Jaffa.

[–] Anticorp 2 points 9 months ago

That's amazing engineering then.

Probably testing bore height vs grip height and how it has an affect on feel, accuracy, etc

A lot of really cool posts there

The FN P90 (matching the text in the pic):

Not only did the FN P90 fire a revolutionary and original ammunition, but it also marked the advent of two significant technological events in the history of gun making at FN. First of all, its patent specified the placement of the 50-round magazine along the barrel and axis of the weapon, while all the machine pistols of the time were still encumbered, either laterally or vertically, by their long magazines. Furthermore, through the power of its spring, the FN P90 magazine itself ensured the rotation and exit of the ammunition into the gun's chamber. Also, for the first time in FN's history, the development team chose to put their faith in the possibilities offered by technical polymers. This choice placed FN Herstal definitively at the forefront of high tech technologies. More than 50 percent of the new arms later developed by FN Herstal would be made of composite materials.

Also famously used in the defense of Earth against the Goa’uld

That thing on the bottom looks like it came from the set of a 1980s sci-fi B-movie.

[–] [email protected] 7 points 9 months ago

Now we get to summon my favorite kind of people. Let’s see if they’re here.

It looks like the bastard child of an assault rifle and a box of Belgian chocolates

[–] [email protected] 4 points 9 months ago

It looks like a carbine version of the USFA Zip .22.

No, the final p90 actually looks like a gun. It's spacy and cool, with weird shapes, but it has all the ergnomics of a gun. #thisisaweaponofwar

That thing looks like like something the badguys use to storm the Enterprise.

[–] ikidd 2 points 9 months ago

I imagine the climb on either of those would be significantly reduced.

[–] [email protected] 1 points 9 months ago (1 children)

I kinda want that naked p90 on the top

[–] [email protected] 2 points 9 months ago

I unironically love that version. Height over bore be damned.
