Shahed drones “are basically a fiberglass body with a motor, basic guidance, and explosives, meaning they can be assembled at a speedboat-repair facility.” They can be manufactured cheaply at thousands of sites, making their production relatively invulnerable to interdiction. This all-important interdiction war is made all that much harder by the US failure to secure command of the air. “Iran’s 358 surface-to-air missiles have a small, mobile launcher but are guided by infrared seekers. They can hit targets at altitudes up to 25,000 feet and because they have no radars, aircraft will have no warning they are being tracked until the missile is launched.” According to the Pentagon, maybe 50% of their prewar missile capacity is left. But the remaining missiles are heavier and more powerful. We also know that the Iranians have hit and disabled all THAAD batteries and all air bases in the region. This means that US warplanes must operate from much longer distances to Iran, reducing the sortie rate and therefore the rate of interdiction. All of this adds up a military crisis. It will take many months, if indeed not years, to suppress Iranian fire and Iran’s ability to blockade Hormuz. That is more than enough to impose intolerable costs on the US.

The US is firing limited advanced munitions - TLAMs, PAC-3s, JASSMs - at a breakneck pace, but replenishing them will take years and billions. Iran is waging a cost-imposing battle on the US defense industrial base -- and its working. @business gift link: bloomberg.com/news/features/…

@FlightsSlow Υπάρχουν όρια ταχύτητας και χρόνου για να είναι εφικτή μια αναχαίτιση (αναλόγως ταχύτητες και θέσεις). Εδώ φαίνεται σαν να έπρεπε να ειχαν απογειωθει νωρίτερα τα PAC.

Δεν μπορώ να το καταλάβω αυτό. Κάθομαι και ρωτάω τον Grok κάθε πέντε λεπτά εάν είναι ψεύτικο μήπως και αλλάξει γνώμη. Τέσσερις PAC2 (ελπίζω όχι PAC3) δεν χτυπούν ΕΝΑΝ βαλλιστικό ο οποίος δεν κάνει καν προσπάθειες αποφυγής χωρίς αντίμετρα σε τέλειες συνθήκες. ΧΩΡΙΣ ΚΟΡΕΣΜΟ αεράμυνας!

Anyone wondering why defense and banking are intertwined, remember Demosthenes: «Δεῖ δὴ χρημάτων, καὶ ἄνευ τούτων οὐδὲν ἔστι γενέσθαι τῶν δεόντων.» "Money is needed, and without it, nothing that must be done can be done." 2,400 years later, that truth has not changed.

Our CEO Dimitrios Kottas (@DimitriosKottas) took the stage at the Goldman Sachs Disruptive Tech Conference in London, sharing Delian's perspective on the defense landscape ahead. Some highlights from his message: 1. “We are not in a 1–2 year cycle; we are entering a 20‑year Cold War–type era. Defense spending will have waves, but the structural shift is here to stay.” 2. “For 10+ years there were no significant procurement events. Defense budgets in Western Europe were at 0.2–0.3% of GDP when the NATO guideline was 2%. During the Cold War, the same ratios were 5%.” 3. “Legacy procurement was built for peacetime: super‑optimized for transparency and fairness, but not for speed or urgency.” 4. “Western governments now need to react quickly and at scale. That means a lot of procurement and a lot of low‑friction changes in how procurement works.” 5. “Some defense primes show real foresight: they’re collaborating with startups, small machine shops, and SMBs to dramatically accelerate their processes.” 6. “We are shifting from procurement for peacetime to procurement for wartime. That mindset shift is as important as any new technology.” 7. “We are arming during a golden era so that we have one, one way or the other. Booms always come with risks and bubbles, but inaction is a bigger risk.” 8. “The rivalry between the West, especially the US and China will drive geopolitics for the coming decades, and defense investment is simply catching up with that reality.” At Delian, we believe that preparing now, boldly and decisively, is the only responsible path forward. Inaction is the greatest risk of all. Proud to share our vision with world-class investors at such a pivotal time.

Iran fired 1200+ projectiles at five countries in the first 48 hours. Most were drones. These saturation attacks aim to overwhelm air defenses and drain interceptors. $20-50k Shahed drones vs. $4.19M PAC-3 interceptors put US and its partners on the wrong side of the cost curve.

10/ The UAE has now burned through a significant chunk of an interceptor stockpile that took years to build — in 48 hours.

@ApoStructura 1. Drones were a major factor in this attack. 2. Long-range drones and hypersonic missiles will be the only weapons that matter when not fighting an opponent several tech levels below you. Aircraft with people in them will unfortunately die very quickly.

Attrition math is brutal in the UAE: 165 intercepts in the first two days. PAC-3/MSE doctrine requires two interceptors per target. It is reasonable to assess the UAE holds roughly 500–600 anti-ballistic interceptors in stock (half is depleted already). Iran may have 3,000–7,000 ballistic missiles. The next 48 hours will be close. The only credible plan is to eliminate as many archers and stockpiles on the ground as possible.

One of the lessons from the conflict in Ukraine is that the only way to keep up with the lightspeed innovation in military tactics and technology is to actually fight a war. Israel found the same. Like it or not, the US battles with Iran are stress-testing our tech in ways no wargames could and that will make them better. China, meanwhile, hasn't fought a war for the past half-century. So when you're comparing the US military vs China, don't just count assets; also count experience.

What happens when you put a 2-stroke engine into a kamikaze USV and "make it fast"? This happens. More coming soon. Stay tuned. Side note: hardware is hard. Maritime hardware is brutal. But that's exactly why we're here. We come from the sea.

Every western military is right now buying FPV drones - while Ukrainians have already moved to mid range and terminal guidance. That’s like training WW2 dogfights when the fight is already happening with jets and heat seeking missiles.

It's funny how people complain about Peter Thiel investing in European Defence but NO-ONE is talking about the facts on the ground: (1) American investors are investing MORE in European defence than European investors. (2) European institutional investors are still investing more over-seas and especially in "grey-zones", very well outside Western influence or democratic rule of law, and less in boosting home-grown defence capabilities.

German Defense Minister Pistorius intends to quickly purchase combat drones — one defense firm’s investor has close ties to US President Trump. Opposition lawmakers have raised concerns. Why the investor’s ties are not an obstacle for Pistorius 👇
