Hey, check this out.
2
Ukraine's Aussie-made cardboard drones are re-writing warfare.
3
And Japan just noticed.
4
Japan's defense minister just posed for a photo with a drone made out of cardboard. $2,000,
5
flat-packed like Ikea, assembled in five minutes.
6
Ukraine already used a nearly identical design to destroy Russian fighter jets on Russian soil.
7
Now, the Russians denied it until the satellite imagery disagreed.
8
So every now and then,
9
And a story comes along that I know I have to cover because it quietly rewrites how we think about modern warfare.
10
Two years ago that story was Ukraine using wax cardboard drones to blow up Su-30s at a Russian airfield.
11
Today, Japan is building its own version.
12
South Korea already has one,
13
North Korea showed off theirs in Pyongyang,
14
and the Australian original is still flying combat missions as we speak.
15
So let's talk about what this technology actually is,
16
where it's proven in combat,
17
and why Japan's entry into the cardboard arms race tells us something genuinely important about where conventional warfare is heading.
18
Hey friends, Wes here, Army and Air Force veteran,
19
defense journalist, and my neighbor just decided now would be the best time to mow his lawn,
20
so this should be fun.
21
What is a cardboard attack drone?
22
Well the original is the Corvo Precision Palo Delivery System or the PPDS,
23
built by Melbourne based Cypac Systems.
24
Crikey!
25
That's right, the corrugated aerospace community was invented down under.
26
The airframe is waxed foam board,
27
cardboard adjacent, waxed to survive the rain,
28
shipped flat packed with tape,
29
rubber bands and glue already in the box.
30
Assembly takes about an hour.
31
weighs 2.4 kilograms empty carries 3 kilograms of payload has a range of 120 kilometers
32
and costs between 670 and 3 000 depending on the version
33
that is extremely cheap for an attack drone although it still
34
feels somehow expensive for cardboard i have a whole garage full of cardboard i'll send it over to ukraine
35
if it'll help now the navigation system is the clever part
36
a ruggedized android tablet connects to the drone through a cable
37
before launch you enter gps waypoints upload the flight plan disconnect it
38
and send it once airborne the corvo flies its entire route
39
autonomously no data link no radio emissions no signal for enemy
40
electronic warfare to grab onto it will navigate by dead reckoning
41
if gps is jammed because the flight plan is already on board The encrypted root data means even if it's captured,
42
the launch location can't be traced.
43
Now, does the cardboard make it basically a budget stealth aircraft?
44
Now, I used to work on the E3 Sentry AWACS.
45
A lot of you already know that.
46
And the question is, could radar detect a cardboard drone?
47
Well, yes, it's dramatically harder to detect than a conventional drone of the same size.
48
The waxed foam board gives it a tiny radar cross-section compared to anything with an aluminum structure.
49
It's slow, it's small, it's lightweight, and it's mostly non-metallic.
50
That's a nasty little radar problem for whoever's defending.
51
But hard to detect is not invisible.
52
The motor, the wiring, the battery,
53
the servos, and the payload all reflect radar energy.
54
The real headache for defenders isn't seeing something, it's classifying something.
55
Seeing a return on radar is one thing.
56
Determining that it's a Corvo PPDES and not a bird,
57
a quadcopter, debris, or whatever else is floating at low altitude near the horizon,
58
well, that's where the Russian operator earns their vodka ration.
59
Really, bro?
60
A large air defense radar is optimized for fast jets and ballistic missiles,
61
but it will genuinely struggle with a slow cardboard drone flying at low altitude.
62
Now a short-range counter UAS radar has a better shot.
63
Think of something like the SeaWiz or the FAMILIX because it's designed for small, low, slow targets.
64
But even then detection range is limited and by the time classification happens the drone may already be inside its attack profile.
65
So what did Ukraine do with it?
66
Well Cypac originally designed the Corvo as a logistics resupply drone
67
built to deliver blood bags to remote medical posts way back in the 2018 Australian Army Innovation Challenge.
68
Ukraine received the first shipments in March of 2023
69
and within months had converted it into a kamikaze strike platform because of course they did.
70
The headline moment came on the night of August 26, 2023.
71
The security service of Ukraine struck a Russian Air
72
and Space Force's base targeting four Su-30s and one MiG-29 aircraft with Corvo PPD-S kamikaze drones,
73
and also destroying an S-300 radar and two Pantsir S-1 air defense systems.
74
16 drones were used, three were shot down,
75
the other 13 got through.
76
Russia denied it happened, but commercial satellite imagery later confirmed it had,
77
exactly as Ukraine described.
78
Now I can tell you that a slow,
79
low, non-metallic emission, silent aircraft is genuinely difficult to build a kill chain around,
80
especially when your sensor-to-shooter loop was designed for supersonic threats.
81
I'm talking about a defensive kill chain here.
82
The Corvo isn't evading radar through its exotic materials or active jamming.
83
It's evading through irrelevance.
84
It simply doesn't look like what the system was built to find.
85
So SIPAC has been delivering 100 Corvo units per month to Ukraine since March of 2023.
86
By mid-2025, that's well over 2,000 airframes through this program alone.
87
The field innovation coming out of Ukraine has been remarkable.
88
Operators cut holes in the fuselage floor and mounted GoPro cameras on a 10-second timer set to fire at the pre-programmed waypoint.
89
The camera captures what it sees,
90
the drone returns, and the entire ISR mission happens in complete radio silence.
91
No data link to jam,
92
nothing to intercept, nothing to trace.
93
Some Corvo units have survived more than 60 flights in Ukraine,
94
patched between sorties with scavenged cardboard from the surrounding environment.
95
A drone, designed to be expendable,
96
has, in practice, become reusable.
97
SIPAC has now released the PPDS-HL for heavy lift variant,
98
which doubles the payload to 6 kilograms and adds external hard points for in-flight payload drops,
99
turning the same airframe into a platform that can function as a precision strike weapon,
100
an ISR asset, a communications relay node,
101
or a decoy, depending on what you mount that morning.
102
But the most tactically significant development from the Kursk strike wasn't the warheads,
103
it was the mix.
104
Ukrainian forces deliberately seeded the swarm with unarmed corvos alongside the armed ones.
105
Defenders couldn't distinguish threats from decoys in real time.
106
Every drone had to be treated as lethal.
107
The response was saturated.
108
The arm units got through.
109
That's intelligent warfare.
110
And here's where this gets genuinely novel.
111
Japan is now building doctrine around that lesson.
112
The cardboard-based Air Kamoi-150 is a swarm platform explicitly positioned for mass deployment in contested island chain geography.
113
Now, Japan is responsible for defending over 6,800 islands,
114
including the Senkaku Islands at the center of an active territorial dispute with China
115
and a southwestern island chain close enough to Taiwan that any conflict there immediately becomes Japan's problem.
116
A Pantsir S-1 carries 12 surface-to-air missiles.
117
A Phalanx Sea Whiz fires 4,500 rounds per minute but has a finite magazine and requires reacquisition time between engagements.
118
Neither system was designed to handle 200 cardboard Japanese drones arriving from multiple vectors simultaneously,
119
half of them unarmed, all of them flying pre-programmed routes with zero radio emission.
120
At $2,000 to $3,000 per unit,
121
an adversary could field 500 Air Kamoi drones for roughly the cost of a single standard missile six used to intercept them.
122
Japan's fiscal 2026 defense budget allocates 312.8 billion yen to unmanned systems,
123
triple the prior year.
124
South Korea has already adopted its own cardboard platform.
125
Even North Korea showcased a rubber band wing cardboard drone at a Pyongyang Defense Expo.
126
The proof of concept Ukraine validated over Kursk in 2023,
127
thanks to Australia, has now been absorbed by three Asian militaries simultaneously.
128
For any weapons technology, that's fast adoption.
129
For one made out of cardboard,
130
it's almost insulting to every defense contractor that spent a decade billing $800 for a coffee cup.
131
But there is an honest caveat here,
132
and that is we don't yet have solid public reporting
133
on how the Corvo has performed and sustained Ukrainian operations beyond that curse strike.
134
The feedback loop between Saipak and Ukraine is tight by design,
135
which also means a lot of it is deliberately quiet.
136
What we do know is that production has continued,
137
adaptation has accelerated, and no one has canceled the program.
138
That's usually a good sign.
139
So, over two years ago when I wrote that Ukraine was proving wars of the future would be fought with cheap,
140
expendable, nearly invisible weapons and that the US and its allies needed to be paying attention?
141
Well, Japan was paying attention,
142
South Korea was paying attention,
143
and apparently North Korea was too.
144
The cardboard drone was never a novelty.
145
It was a proof of concept.
146
It passed and now it's a doctrine.
147
The Air Kamoi 150 didn't come from nowhere.
148
It came from Kursk.
149
It came from Ukraine.
150
Okay, that is it for today, my friends.
151
Subscribing is the best free way to support my channel.
152
If you want deeper analysis on the weapons and the geopolitics shaping the next decade,
153
check out the substack for deeper dives.
154
I write there five times a week.
155
I know, four videos a week and five articles is kind of insane,
156
but this is my full-time job now.
157
And as always, glory to Ukraine, glory to the heroes.
158
Crimea is Ukraine.
159
Hey my friends, I am just fixing my hair before the video.
160
This is where I look into the monitor and here we go.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
