Drone Stack — The Weapon of This Decade

Framework taken from Coffee House Stocks (@CoffeeStocksGuy), 4 Mar 2026. The March note mapped drones as a seven-layer industrial stack and priced a $45B → $400B TAM. Five months later the tape has already sorted the book: UMAC / AMPX / PL held or ran; AVAV / KTOS / DRO de-rated hard from the March peak. The question now is not “are drones real” — it is which layer still has unpriced execution.

Cost asymmetry

A Shahed-136 is $20–38k; a Patriot interceptor is >$3M. A $500 FPV can kill an $82.5M F-35. Ukraine’s Spider’s Web: $234k of drones vs ~$7B of Russian bombers. The defender’s intercept economics are broken unless C-UAS is cheap, layered, and recurring.

The $400B framing

Oppenheimer (27 Feb 2026) called drones the fastest physical-AI pocket. Grand View: $83.8B (2025) → $182.5B (2033). Warfare subsector $75.8B by 2035. Anti-drone $2.7B → $34B (28.8% CAGR). Lower-skies (C-UAS + tactical UAS + UGS) grows at 2× the broader defence market.

What the tape already did

March priced the Iran-war “years of demand into months” story at peak multiples. AVAV $17.7B → $9.6B. DRO $2.5B → $1.3B. UMAC $511M → $1.36B. Thesis intact; entry prices are not March prices.

Coffee House: “The country that can mass-produce cheap attritable drones and simultaneously build layered counter-drone defences will define the next era of military superiority.” That is the same industrial-war point as the sibling Intelligent Mass tab — this page is the drone-specific, company-by-company cut of that stack.

The 7-layer supply chain

Layers 1–5 and 7 are Coffee House’s original map. Layer 6 was never named in the post (a reply asked; no answer). We fill it as comms / spectrum / private production capacity — flagged as interpolation, not source.
Layer 1
Counter-drone (C-UAS)
Most direct Iran-conflict bid
Ondas (ONDS) — Iron Drone Raider (net interceptor) + Sentrycs Cyber-over-RF (takeover, not jam) + World View ISR. Street now prints $530M 1FY sales vs $51M TTM — that is a 10× ramp the market is already paying 22× trailing sales for. DroneShield (DRO.AX) is the cleanest listed C-UAS pure-play (DroneSentry / DroneGun / RfPatrol). FY25 A$217M / first profit, but 4-week sales revisions are −A$67M / −A$99.5M and the stock has halved from the March $2.5B print.
ONDS · DRO.AX
AVAV BlueHalo
Layer 2
Manufacturers + CCA
Visible · already owned
AeroVironment (AVAV) — Switchblade 300/600 consumable munitions (razor/blade). TTM sales now $1.98B; 1FY street $2.19B. Best downside floor in the original note, and the market treated it that way by cutting it from $17.7B to $9.6B. Red Cat (RCAT) — Black Widow / FANG, Blue UAS, FCC Chinese-drone ban as the regulatory moat. Execution still the risk (Q3’25 miss). Kratos (KTOS) — XQ-58A Valkyrie loyal wingman + hypersonics ($400M → $700M path in the March note). Closest listed CCA analogue; still 78× 1FY EPS.
AVAV · RCAT · KTOS
Anduril / Neros / PDW
Layer 3
Batteries (silicon anode)
Binding constraint
Amprius (AMPX) — 520 Wh/kg silicon-anode cells (≈2× graphite), 80% charge in ~6 min, NDAA path (DoD battery China/Russia ban from Jan 2028). Customers cited: AVAV, L3Harris, Teledyne FLIR, Airbus AALTO. TTM $73M → street $141M / $212M. One of the few names that is up YTD (+51%) after the March note. Physics moat is real; production scale is the kill condition.
AMPX
Layer 4
Components (motors / FC / cameras)
Highest beta · call option
Unusual Machines (UMAC) — NDAA-compliant motors, Aura camera/VTX, Brave FC/ESC, FANG with RCAT. March mcap $511M → $1.36B (+166%). Street 1FY sales $56M on $11M TTM — still a story stock (38× trailing sales). This is the name the original note called “highest asymmetry, highest risk.” The asymmetry compressed. Domestic motor cost-parity vs T-Motor is still the proof point.
UMAC · RCAT FANG
Layer 5
ISR / satellite imagery
Strategic layer, not tactical
Planet Labs (PL) — 200+ Dove/Pelican birds, daily global revisit, $435M / $569M street sales, $735M backlog in the March note. Drones are tactical; satellites cue them. Not on the Obsidian watchlist until this wiring. Also NextVision (NXSN.TA) — micro-stabilized drone cameras, already on the defense watchlist; 2026 guide $315M, street now $356M / $492M, 60% operating margin. The profitable optics pick in a book of loss-makers.

Layer 6 · interpolated
Comms, spectrum, private factories
Blank in the source post
Coffee House never defined Layer 6. Working fill: licensed spectrum + private production. FCC-24-91 5 GHz drone band (RCAT catalyst). Private builders that actually win Phase I/II Gauntlet — Neros, PDW, Powerus, Teal, Firestorm — plus ONDS Drone Factory 01 (100k/yr, Huntsville). If Neros/PDW IPO, they absorb the scarcity premium currently sitting in RCAT/UMAC/ONDS.

FCC 5 GHz · Factory 01
Layer 7
Autonomy software
GPS-denied brain
Shield AI (private) — Hivemind on F-16 / MQ-20 / drones in comms-denied airspace. $5.3B post $240M Series F (Mar 2025); L3Harris, Hanwha, a16z. Public expressions: PLTR (neutral C2) and AVAV mission software. Same “software layer still up for grabs” fight as Intelligent Mass / Lattice.

Allocation framework (source) vs what we would actually hold

Coffee House’s March buckets, restated against August prices and estimate momentum.

1Core — AVAV + KTOS

Still the right floor names. Both already did the de-rate the March note warned about (AVAV −46% mcap, KTOS −24%). Street sales still growing (AVAV $2.19B / KTOS $1.78B). Multiples remain rich on EPS (57× / 78×) because earnings have not caught sales. Use as theme ballast, not a new high-beta bid.

2C-UAS — ONDS + DRO

ONDS is now a ramp story the street already believes ($530M 1FY vs $51M TTM). 1FY EPS +$0.39 flipping to 2FY −$0.24 is not a clean PE — ignore the 23× and watch bookings vs $530M. DRO is the opposite: profitable, pipeline was A$2.3B, but estimate momentum is negative and the stock has already paid for that. Prefer architecture (detect + defeat + C2) over a single effector.

3Moat — AMPX

Original “most attractive risk/reward” call is the one that worked (+51% YTD, street sales $141M / $212M, 4-wk sales +$8M). NDAA 2028 forced-buyer still ahead. Scale and margin path remain the kill. This is the layer Intelligent Mass would call “picks and shovels with physics.”

4High-beta — RCAT + UMAC

Regulatory moat (FCC Covered List / T-Motor OFAC) is intact. UMAC already repriced from option to story stock ($1.36B on $11M TTM). RCAT is cheaper on the 1Y tape but still 17× trailing / 10× 1FY sales with negative EPS. Size as if manufacturing can fail.

5Data / sensors — PL + NXSN

PL is the strategic ISR anchor (lossy, 24× sales). NXSN is the only profitable, high-margin name in the public drone book (60% EBIT, 40× trailing, street $356M). Cameras ride every airframe. Add both to the live watchlist theme with this wiring.

6IPO watch — Shield AI

Not investable. Hivemind-as-Android is the software endgame the public book cannot buy cleanly (PLTR is the expensive proxy). Watch the S-1. An IPO would also re-rate how much scarcity premium AVAV software and PLTR “defence AI” can keep.

March note vs August tape

Coffee House published into the Iran-strike tape (Operation Epic Fury / Roaring Lion). Five months on:

  • UMAC $0.51B → $1.36B — the call option paid; asymmetry is now thinner
  • AMPX $1.52B → $1.74B — only US name up YTD in the original list
  • ONDS $4.50B → $5.08B — mcap held; street sales exploded to $530M
  • AVAV $17.7B → $9.6B · KTOS $15.5B → $11.8B — autonomy de-rate
  • DRO $2.51B → $1.28B — profitable C-UAS cut in half
  • PL $8.99B → $8.82B · RCAT $1.75B → $1.56B — roughly flat

How this tab sits on the hub

Wired three places so the theme is not trapped in one app:

  • This page — DIB tab ?tab=drone and a homepage card
  • Intelligent Mass — Anduril / Schimpf stack (platforms, Lattice, motors). Broader than drones.
  • Watchlist → Defense & Drones — live Yahoo prices for the listed names (AMPX, DRO.AX, PL added with this wiring)

Obsidian theme note: US Drone Dominance.md (updated 2026-08-14).

How this tab relates to Intelligent Mass + munitions chokepoints

Three cuts of the same war. Chokepoint Dashboard asks where motors, energetics and seekers physically narrow. Intelligent Mass asks how AI + autonomy rewrite what gets bought. This tab asks which public drone-stack securities express that rewrite, layer by layer. Cheap attack drones increase demand for C-UAS, batteries, NDAA components and for SRM / interceptors on the munitions book. They do not retire the chokepoint map.

Private reference set

Shield AI $5.3B (Hivemind). Anduril $61B / $2.2B sales (Lattice + mass). Neros $120M+ (Blue UAS Archer). PDW $200M+ incl. $35M from ONDS (Army C100). If the private cohort IPOs, public scarcity proxies (RCAT / UMAC / ONDS) lose the “only way to buy US drones” bid.

Kill / invalidate

FCC / NDAA China-drone rules reversed · ONDS $530M street collapses back toward $50M · AMPX misses NDAA 2028 qualification · UMAC never reaches Chinese motor cost-parity · DRO pipeline does not convert (revisions already warning) · Neros/PDW IPO absorbs the premium · exquisite-only procurement returns.

Working checklist

Bookings vs street sales (ONDS $530M, RCAT $151M, UMAC $56M) · DRO 4-wk revisions · AMPX Fremont / NDAA line · UMAC US motor plant · Phase II Gauntlet winners · Shield AI S-1 · Switchblade reorder cadence · NXSN margin hold at $315M+ guide.
