A £500m funding round for drone maker UForce has put unmanned and naval defence technologies firmly in the spotlight, with UK state money now flowing directly into this space. That combination of private capital and government backing can reshape contract pipelines and sentiment around listed defence stocks. This article picks out 3 UK companies exposed to that same news trend and explains why some investors are watching them closely right now.
The stocks covered below are just a starter set, and the full screen on Simply Wall St surfaced 7 more UK and London-listed defence and aerospace companies with unmanned or naval angles that are not covered in this article but may have equally compelling stories. To identify, analyse and pressure test your own highest-conviction ideas in this niche, head straight to the UK defence and aerospace – unmanned and naval systems screener.
Cohort (AIM:CHRT)
Overview: Cohort is a defence technology group that supplies command systems, sensors and electronic equipment that help power unmanned and naval platforms for allied militaries worldwide.
Operations: Cohort generates about £159 million from Communications and Intelligence and £147 million from Sensors and Effectors, with revenue spread across the UK, Europe and allied export markets.
Market Cap: £589.2 million
Cohort matters for this unmanned and naval screen because its communications, sonar and electronic systems are the kind of behind the scenes kit that lets drones and uncrewed vessels actually work together at sea. The bearish analyst Narrative on Simply Wall St views this through a more cautious lens.
Although global defence spending is rising and Cohort has an order book of over £600m that extends into the mid 2030s, long development and acceptance cycles on programs such as the Italian Navy submarine contract, with around £10m of provisions still held, mean any slippage in testing or sea trials could delay revenue recognition and keep net margins under pressure for longer.
For investors watching Cohort, a single unseen pressure around unmanned naval delivery timing could end up mattering far more than headline demand.
That kind of timing risk is only one piece of the puzzle, and the full narrative for Cohort shows how Cohort’s pipeline, cash profile and contract mix could be decoupling from headline worries.
Chemring Group (LSE:CHG)
Overview: Chemring Group supplies defence clients with countermeasures, sensors and specialist energetics that support drones, unmanned surveillance and naval protection systems worldwide.
Operations: Chemring Group generates about £177 million from Sensors & Information and around £335 million from Countermeasures & Energetics, highlighting a heavy tilt toward expendable protection products.
Market Cap: £1.43 billion
Chemring Group matters for this unmanned and naval screen because its countermeasures, detection technology and energetics feed straight into how drones, ships and aircraft protect themselves and gather data. This aligns with what the analyst consensus Narrative on Simply Wall St focuses on.
The record £1.4b order book, with 91% of FY 2026 revenue already delivered or covered by orders and high multi year coverage in both Countermeasures & Energetics and Sensors & Information, gives Chemring Group multi year visibility that can underpin future revenue growth and support operating leverage.
What happens to Chemring Group’s valuation story now largely depends on how one unresolved execution swing factor feeds through to margins.
If that swing factor has you curious, the full narrative for Chemring Group shows where contract visibility, pricing power and execution risk may be quietly pulling Chemring Group’s story forward.
TT Electronics (LSE:TTG)
Overview: TT Electronics designs and manufactures advanced power electronics, sensors and connectors that support mission critical aerospace, defence and unmanned naval systems.
Operations: TT Electronics generates about £472 million in revenue, with £173.5 million from North America, £108.5 million from Asia and £103 million from the United Kingdom.
Market Cap: £323 million
TT Electronics matters in this unmanned and naval screen because its power systems and sensors sit inside the drones, radars and combat platforms that investors are watching. The analyst consensus Narrative on Simply Wall St describes how that defence exposure could influence the long run earnings story.
Rising global defense and civil aviation spending, supported by multi year program awards such as the recent contract with Kongsberg, is expected to sustain high value, long duration orders and support continued revenue growth and operating margin expansion.
What happens to TT Electronics’ investment case now hinges on how one quiet shift in contract mix ultimately flows through to margins and cash.
That contract mix shift is exactly what the full narrative for TT Electronics unpacks, separating cyclical noise from where TT Electronics’ defence exposure could be quietly accelerating.
