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.

Don't get it
Flying deathtrap. VP on an Osprey, we just witnessed an assassination attempt!
It's a layered joke about an Osprey's safety record.
Ignore them. They're just haters who can't handle the fact that despite it's youth, the Osprey is already a legendary platform.
Think of it like the A-10, except instead of repeatedly slaughtering friendly forces, it just regularly kills anyone dumb enough to ride in one, or pilot it.
It's called a meritocracy!
fudds like to call the osprey a death trap because they read some headlines early on and never bothered looking into the data. that's my understanding of it, as i have also not looked into the data.
Unlike helicopters, they cannot autorotate, meaning if you lose power in any position other than forward cruise, you're fucked. Asymmetric power loss is also extra bad.
The design is inherently less safe than either a helicopter or a fixed wing aircraft.
again, as someone who doesn't know much about this, aren't they only using the VTOL configuration during takeoff and landing? and, doesn't auto rotation require a certain amount of altitude? if both of those are true, then they would be in danger at the same time
They're flying with the engines facing at least partially upwards during takeoff and landing, even when taking off like an aircraft, meaning they're in trouble if they lose power, not just in a hover. The Japanese crash happened on final approach as they were slowing down, but still a few hundred feet in the air.
https://en.m.wikipedia.org/wiki/Helicopter_height%E2%80%93velocity_diagram
This is the combination of airspeed and height you cannot perform an autorotation from, the graph shown is worse than many other helicopters. Robinson aircraft can auto from zero airspeed at around 400 feet. It's all about having enough forward speed to flare off your rate of descent and land with only forward airspeed, you could successfully flare at head height and enough airspeed over good ground.
Other tiltrotors are capable of autorotation.
I like that the chart there has a little red sliver to indicate that it is, in fact, a bad idea to fly very fast at ground level.
Anecdotal, but I almost exclusively see them flying in VTOL configuration
That's at least partly because that's the easiest time to photograph an aircraft.
I don't mean in photos, they just fly around town in VTOL configuration all the time. Hardly ever see them at full tilt.
