XTI Aerospace ( $XTIA ): Defense Drones and Urban Air Mobility at an Inflection Point

XTI Aerospace, Inc. (NASDAQ: XTIA) is an aerospace and technology platform combining vertical flight aircraft development, unmanned aircraft systems, and enterprise drone distribution. As of March 2026, the company is in the early scaling phase following its transformational November 2025 acquisition of Drone Nerds.
BlackSky (NYSE: $BKSY) — why the story looks stronger in March 2026

BlackSky has turned a familiar speculative space name into something the market is finally trying to reprice as real defense-tech infrastructure. Fourth-quarter numbers were solid, backlog expanded, a new seven-figure NGA Luno delivery order added another official validation point, and then management followed with two operational milestones that matter more than the typical space-company headline: Gen-3 first light arrived within hours, and the fourth Gen-3 satellite was commissioned in less than a week, opening general availability of the company’s best-in-class 35-centimeter imagery and AI-enabled analytics to global customers. The bullish case is no longer based only on a distant dream of “space growth.” It is increasingly built on the idea that BlackSky is becoming a usable, taskable, software-connected intelligence layer for governments that need decisions faster, not just prettier satellite pictures.
Ondas and Palantir ( $ONDS ) ( $PLTR ) a real defense-tech stack? (Part 2)

The first article explained the announcement. This second one tackles the harder question: whether the Ondas–Palantir–World View structure can evolve into something commercially meaningful, or whether the market is still looking at a strategically attractive partnership that remains too early to change fundamentals.
Palantir Ondas and World View just sketched a much bigger story than a normal partnership headline (Part 1)

Palantir, Ondas and World View announced a partnership to develop a next-generation multi-domain intelligence platform, using Palantir AIP across production, mission planning and edge operations.
Castellum ($CTM) — 2025 repaired the story

Castellum came out of 2025 looking cleaner, less leveraged and more credible than it did a year earlier. Revenue grew, operating losses narrowed sharply, cash improved, debt was almost fully gone by year-end and then fully eliminated shortly after. The central question now is no longer whether CTM can tell a better story, but whether it can turn backlog, contract wins and pipeline into durable margins and more repeatable cash generation in 2026.
Ondas (NASDAQ: $ONDS) — preliminary 2025 earnings beat and Mistral merger agreement Updated mach 10

A long-form bilingual deep dive on what changed in Ondas’ preliminary fourth-quarter and full-year 2025 update, why the revenue beat matters more than the raw numbers alone, how the Mistral agreement changes the strategic map, and what investors should watch next as ONDS tries to move from fast-growing defense-tech vendor to a broader autonomous systems platform with prime-contractor access.

ZenaTech Inc ( $ZENA ) deep dive on the story filings ownership governance

A structured review built around the most relevant SEC filings from the last year, with special attention to what is real already, what is still mostly forward story, how the acquisition machine is being used to create revenue, and where the governance and financing risks are concentrated.
Drone stocks explained: the listed names that matter $AVA $ONDS $RCAT $DPRO $KTOS $UMAC

A comparative, long-form guide to the main quoted drone and counter-drone names retail investors keep putting in the same basket — from AeroVironment and Kratos to Ondas, Red Cat, Draganfly and Unusual Machines — with a focus on what each company really does, where the real business sits, and where the story is still more narrative than scale.
The War Economy

The market is no longer treating Middle East escalation as a passing geopolitical shock. It is increasingly pricing it as a broader economic regime: one that reprices oil and LNG, lifts defense and dual-use space names, pressures airlines and small caps, and forces investors to rethink the physical vulnerability of cloud infrastructure
Castellum Inc ($CTM) – FY 2025 Results & 2026 Execution

On March 4, 2026, Castellum Inc. announced its unaudited FY 2025 financial results, and the numbers reveal a company that has fundamentally shifted trajectory. After years of acquisition-driven roll-up activity, balance sheet stress, and constant capital raises, CTM is now reporting organic revenue growth, positive adjusted EBITDA, and—perhaps most significantly—has completely eliminated all outstanding debt. This is not a dramatic overnight turnaround; rather, it is the culmination of methodical execution: progressive debt paydown, operational efficiency improvements, successful Navy contract wins, and a disciplined capital allocation strategy that prioritizes sustainability over growth-at-any-cost.
Palladyne AI Corp ( $PDYN ) Deep Dive after Q4 & 2025 Full year Results

A detailed look at Palladyne AI’s fiscal 2025 numbers, backlog and capital structure after the latest annual report and guidance update.
Ondas – $20M initial border-defense order ( $ONDS )

Ondas’ Airobotics subsidiary has received a $20 million initial purchase order as prime contractor under a strategic national Autonomous Border Protection Program – the formal launch of a multi-year, multi-phase architecture built around thousands of AI-driven drones.
Mobix Labs Inc ( $MOBX )

Mobix Labs, a tiny defense and connectivity component supplier, just caught a massive bid after announcing a new production order for its high-reliability filtering component inside the U.S. Navy Tomahawk cruise missile program. Behind the headline, the story is a mix of real programs (Tomahawk, M-1 Abrams, drone platform), aggressive M&A, heavy dilution and a very tight liquidity position.
Red Cat Holdings Inc ( $RCAT )

Red Cat has announced that Allen Control Systems (ACS), a specialist in autonomous precision weapon systems, is joining the Red Cat Futures Initiative – the company’s consortium aimed at accelerating advanced robotics and autonomy for modern warfare. The core of the deal is the integration of ACS’s Bullfrog system, an AI-driven robotic weapon station designed for counter-drone and precision engagement roles.
Red Cat Holdings Inc ( $RCAT ) From niche drone supplier to all-domain autonomy play

Red Cat is positioning itself as a U.S.-based provider of all-domain unmanned and autonomous systems rather than as a simple “drone stock”. The company aggregates several assets under one umbrella:
Ondas Inc ( $ONDS ) $10M stratospheric ISR bet with World View

$10M strategic equity investment in World View and a partnership to integrate persistent stratospheric platforms (Stratollite®) with Ondas’ autonomous UAS and counter-drone capabilities for multi-layer ISR and airspace defense.
WAR US–Israel vs Iran, 2026 Small & mid-cap potential “winners & losers”

Focus on factual developments of the last few days (Strait of Hormuz, tankers at anchor, oil spike) and on a sector-based watchlist – not on trying to predict the endgame of the conf
BigBear.ai Holdings Inc ( $BBAI )

BigBear.ai is trying to turn years of work in defense intelligence, mission planning and logistics optimization into a scalable AI platform story, boosted by large capital raises and the acquisition of generative-AI partner Ask Sage. Revenues are meaningful and the cash cushion is large, but the path from contract wins to durable, profitable growth remains complex and execution-dependent.
