Escalating drone attacks on Russian logistics hubs and commercial shipping in the Black Sea are a stark reminder that geopolitical risk can ripple quickly through global supply chains, energy flows, and defense spending priorities. For investors, it raises the question of which stocks might benefit from higher demand for surveillance, counter drone technology, and secure logistics, and which could face greater operational risk. This article looks at 3 stocks from a Defense and Military Technology screener that appear positively exposed to the latest developments, to help you decide whether they deserve a closer look in your own research process.

Amprius Technologies (AMPX)

Overview: Amprius Technologies develops, manufactures, and sells high energy density lithium ion batteries, using silicon anodes under its SiCore and SiMaxx platforms, mainly for aviation uses such as drones and high altitude pseudo satellites. Its products are aimed at customers that need long endurance, lightweight power solutions for demanding mobility and defense applications.

Operations: Amprius generates about US$90.3 million of revenue from its Battery Business, with sales spread across EMEA at US$62.8 million, North America at US$15.9 million, and Asia Pacific at US$11.5 million.

Market Cap: US$1.46b

Amprius Technologies operates at the intersection of rising drone usage and the need for longer flying, lighter aircraft. This makes its silicon anode batteries directly relevant as militaries look for endurance and range advantages. Recent commentary from management highlights customer urgency around reconnaissance drones. At the same time, guidance for at least US$130 million of 2026 revenue and a much smaller expected net loss indicates that the business is scaling, even though it is not yet profitable. The stock still carries clear risks, including heavy exposure to aviation and drones, high funding risk, volatility, and recent insider selling. However, with premium battery performance, defense-linked demand, and strong growth forecasts, there is more to the Amprius story than recent share price swings alone suggest.

Amprius Technologies sits at the crossroads of urgent drone demand and premium battery performance, yet the real inflection point may be hiding in the analyst forecasts that feed into the analyst forecasts for Amprius Technologies

Swarmer (SWMR)

Overview: Swarmer develops software and AI that lets military customers coordinate large numbers of drones and unmanned systems across air, ground and maritime domains through a common command and control platform.

Operations: Swarmer currently generates about US$0.2 million of revenue from Software & Programming services, all from Eastern Europe.

Market Cap: US$404.2 million

Swarmer operates in the area of autonomous drone coordination and counter drone capabilities, a focus that has become more prominent as recent attacks on Russian logistics hubs and shipping highlight the need for scalable, software driven defenses and secure data links. The company is at a very early stage with around US$220,000 of revenue, ongoing losses and high share price volatility. Recent contracts, partnerships and more than 100,000 combat missions provide real world deployment evidence. At the same time, limited financial history, high spending and reliance on defense procurement cycles create execution risks that investors need to assess carefully.

Swarmer sits at the edge of real world combat use and early stage revenue, yet few investors seem to be joining the dots. The 2 key rewards and 3 important warning signs (2 are major!) could highlight what the headline story is missing.

EHang Holdings (EH)

Overview: EHang Holdings develops autonomous passenger carrying and industrial drones, building a full urban air mobility platform that covers aircraft, flight control software, vertiports, charging, and operational services for transport, logistics, smart city management, and aerial media across multiple global regions.

Operations: EHang currently generates about CN¥417.5 million of revenue entirely from its Aerospace & Defense segment.

Market Cap: US$411.1 million

EHang Holdings provides exposure to urban air mobility at an early stage, with autonomous eVTOL aircraft, a dual hardware plus services model, and backing from government partners that see its technology as core to low altitude smart city projects. The company is still loss making, heavily reliant on China, and faces a challenging regulatory and certification environment following recent incidents and analyst downgrades. As drone warfare, logistics risk, and low altitude regulation receive increased attention, a key consideration for investors is how much of EHang’s potential is already reflected in the share price and what the latest guidance and delayed commercialization imply for long term returns.

EHang Holdings sits where early stage urban air mobility intersects with government backed smart city projects, yet many investors may be missing how the story fits together. The full narrative for EHang Holdings could surface one crucial twist that changes how you see the risk reward equation.
