Defence prime contractors are buying robotics companies at a pace that has nothing to do with the consolidation waves of the 1990s. They are buying to secure autonomy architecture before the next conflict determines which designs become standard.
$54.6 billion in autonomous warfare spending, a 24,000% year-over-year increase, is flowing into drones, ground robots, and uncrewed maritime systems. That money has to land somewhere. It lands on companies with proven autonomy stacks, not on prime contractors trying to build them from scratch — which is why the primes are buying instead of building. The six-company hunter-killer demonstration in early July — where AZAK, HavocAI, Leonardo DRS, Allen Control Systems, Picogrid, and Anduril integrated a fully autonomous ground vehicle system in under a week for the Secretary of the Army — showed what modular open architecture can deliver when primes and startups collaborate at speed.
Anduril has acquired four companies in three years (Blue Force Technologies, Numerica, Adranos, and a fourth undisclosed sensor firm). Ondas bought autonomous aircraft maker DZYNE for $875.8 million in July 2026. Kraken Robotics closed its $615 million acquisition of Covelya Group — one of the largest subsea robotics deals in history. Agility Robotics went public via a $2.5 billion SPAC merger in June.
The pattern is structural: as we wrote in July, defence procurement reform is creating demand for commercial robotics platforms. The M&A wave is the supply-side response.
Global defence spending reached $2.63 trillion in 2025, up from $2.48 trillion in 2024, according to the International Institute for Strategic Studies. Venture capital flowing into defence technology more than doubled to $49.1 billion, more than the previous three years combined. Robotics alone captured $27.6 billion, with defence and security robotics drawing $8 billion of that, a 139% year-over-year surge. Autonomous drones were the largest subsegment at $6.2 billion across 169 deals on a trailing-12-month basis, driven by combat validation in Ukraine and the Middle East. Uncrewed maritime systems raised $944 million and autonomous ground vehicles secured $512 million, per PitchBook.
The traditional exit for a venture-backed defence startup has been ambiguous. IPOs are rare — the Pentagon is not Nasdaq. The path that is crystallising is acquisition by a prime contractor or by a defence-tech platform that behaves like one.

What primes are buying
The M&A pattern breaks into three distinct categories. The first is platform consolidation — a defence-tech company buying adjacent technology to fill a product gap. Anduril's acquisition of Numerica's radar and command-and-control business in January 2025 brought RF sensing in-house, complementing its Lattice software platform. Its purchase of Blue Force Technologies in 2023 added Group 5 autonomous aircraft capability. Each deal filled a specific architecture slot, not just a balance sheet target.
The second category is prime contractor partnerships that function as de facto acquisitions. Forterra, an autonomous mission systems company, secured the U.S. Marine Corps' ROGUE-Fires Block 2 production award in June 2026 alongside prime contractor Oshkosh Defense — the military's first large-scale production contract for ground vehicle autonomy. The $92 million award gives Forterra long-term revenue visibility without requiring a change of control, but positions it as an Oshkosh-aligned autonomy supplier.
The third is the pure M&A play where scale matters. Ondas's $875.8 million acquisition of DZYNE Technologies in July combined long-endurance autonomous aircraft, counter-drone systems, and stratospheric intelligence, surveillance, and reconnaissance (ISR) into a single operating platform with an integrated AI mission system developed in partnership with Palantir.
New cross-border patterns
The consolidation is not limited to the United States. In India, LAT Aerospace, a venture from Zomato founder Deepinder Goyal, acquired defence robotics startup Sharang Shakti in February 2026, its first move into defence technology. In Canada, Kraken Robotics' C$615 million acquisition of Covelya Group in July 2026 created a combined subsea technology business with 1,200 employees, 110 patents, and an estimated $351-379 million in 2025 pro-forma revenue, transforming a niche sensor firm into a global defence supplier with operations across North America and Europe. In Europe, the European Investment Fund committed €50 million to Join Capital Fund III under the InvestEU Defence Equity Facility, explicitly targeting deeptech and dual-use startups. The NATO Innovation Fund is also a limited partner in Join Capital.
European prime contractors are responding in kind. Rheinmetall has made multiple investments in autonomy and robotics. BAE Systems acquired Malloy Aeronautics. Helsing, the German AI-defence startup, has acquired more than half a dozen mature Mittelstand companies in a private-equity-style rollup that is functionally a consolidation play disguised as a startup story.
Deloitte's analysis of the European defence innovation ecosystem characterises prime contractor M&A as "the most common exit path" for venture-backed defence startups — and notes that the pathway from prototype to production, typically requiring Series B or later financing, "remains somewhat barren." The implication is structural: institutional investors remain cautious due to ESG frameworks, regulatory fragmentation, and narrow liquidity options. Strategic acquisition fills the gap that public markets cannot.

Investment thesis: the consolidation premium
The M&A wave creates a specific dynamic for investors evaluating defence-adjacent robotics companies. Startups that reach a meaningful technology readiness level — TRL 7 or above with a deployed customer — become acquisition targets for primes that cannot replicate the capability in-house within a procurement cycle. This caps the downside for late-stage venture investors while limiting the upside: the exit multiple is strategic (typically 3-8x revenue for a defence-tech acquisition) rather than the double-digit multiples of a growth-stage tech IPO.
The data supports a bifurcation. Companies with dual-use platforms — technology that works in both commercial and defence contexts — command the highest acquisition premiums because their addressable market is not limited to Pentagon budgets. Forterra's AutoDrive autonomy stack, for example, powers both military ground vehicles and commercial off-highway equipment. Kraken's synthetic aperture sonar sells to naval forces and offshore energy operators. The dual-use credential is becoming the single strongest predictor of exit value in defence robotics.
For limited partners evaluating defence-tech fund exposure, the trend signals a maturing asset class. The presence of the EIF, NATO Innovation Fund, and sovereign investors in defence-tech venture funds suggests that institutional capital is moving from "excluded by mandate" to "measured allocation." Deloitte estimates that European defence-tech VC could absorb €5-8 billion annually by 2028 if current growth trajectories hold — up from approximately €1.5 billion in 2025. The consolidation wave is both a symptom of that maturation and a mechanism that enables it: clear exit paths make institutional investors more comfortable deploying capital.
The risk is concentration. If the current M&A pattern continues — a small number of primes and defence-tech platforms acquiring most of the viable robotics startups — the sector risks recreating the same oligopoly structure that defined the post-1993 defence industry consolidation. The "Last Supper" of 1993 turned 50+ defence contractors into five primes: Lockheed Martin, Boeing, Raytheon, Northrop Grumman, and General Dynamics. The current wave may produce a similar outcome for autonomy-specific capability. The difference is that this time, the acquirers include nontraditional primes like Anduril and Palantir alongside the incumbents. Investors should track which primes are buying in which subdomains: the pattern reveals where the next structural bottleneck will form.
Key signals to track
1. Prime contractor M&A targets. Watch which autonomy startups primes acquire in the next 12 months. The deals reveal which capability gaps they consider urgent vs. buildable in-house.
2. Defence SPAC pipeline. Agility's $2.5B Churchill Capital merger is the test case for whether public markets can absorb defence-adjacent robotics companies.
3. European consolidation velocity. If Rheinmetall, BAE, or a U.S. prime acquires a European autonomy startup, it signals the cross-Atlantic M&A channel is open.
4. Private equity entry. Deloitte flags PE as "Europe's most powerful defence finance mechanism" if it steps into the Series B gap. Fund formation data will tell whether that materialises.
