Find the right platform
for the water you work in.
Our defence portfolio spans portable ROVs, hovering and zero-visibility AUVs, wireless micro-vehicles and diver-held sonar. This page puts them side by side — so you can start from the mission, narrow by capability, and get to the right system fast. When several platforms could do the job, we scope the mix for you.
Choose by mission
The fastest route. Pick the job and we lead with the platforms — and the cross-supplier package — that fit it.
Mine Countermeasures & EOD
Wide-area survey, re-acquisition, diver search and acoustic disposal — robot first, diver last.
See the mission →Coast Guard & Border
Faster hulls, cleaner hull and anchorage searches, and wider maritime coverage.
See the mission →Police & Public Safety
Underwater search, evidence and weapon recovery — with or without a diver.
See the mission →Critical Infrastructure
Survey, inspect and defend cables, pipelines and the seabed estate.
See the mission →The platform matrix
Seven platforms across every underwater vehicle class. Click any name for its full page and specifications; full datasheets are sent on request — just ask.
| Platform | Best for | Class | Typical depth | Deployment | Link & control |
|---|---|---|---|---|---|
| Blueye X3 Ultra Blueye |
Rapid first look, ISR and diver-safe reconnaissance under hulls and jetties | Portable observation ROV | ~305 m | One person, backpack | Tethered · piloted |
| SEAMOR Chinook SEAMOR Marine |
Manipulator recovery of evidence, weapons and ordnance; forensic survey | Inspection & recovery ROV | 300 m (fleet to 1,000 m) | Two person, portable | Tethered · piloted |
| Tethys One Tethys Robotics |
Zero-visibility, strong-current search & recovery where a diver can't work | Hybrid ROV / AUV | 300 m | Two person, ~10 min setup | Tethered link · autonomous |
| A.IKANBILIS BeeX · HAUV fleet |
EMCON-safe seabed survey, MCM support and infrastructure inspection at scale | Hovering AUV (HAUV) | 150 m | Hand-portable, 60 kg class | Untethered · autonomous |
| ExRay Hydromea |
Confined-space inspection and covert hull search — no umbilical to snag or signal | Wireless micro-ROV | 200 m | Hand-portable | Tetherless · optical (LUMA) |
| AUV COMET-MCM RTsys |
Wide-area mine survey with side-scan sonar and magnetometer, solo or in a swarm | Man-portable MCM AUV | On request | Two person, man-portable | Untethered · autonomous |
| SONADIVE RTsys |
Systematic diver search, navigation and acoustic comms in black water | Diver-held sonar & navigation | Diver depth | Handheld, one diver | Diver-carried console |
Figures are indicative and configuration-dependent; full technical datasheets are provided on request. Depths and payloads vary by build and mission fit.
Which one? Answer a question.
A quick decision aid. Most real taskings combine two or three of these — which is exactly what we scope as one package.
I need a fast first look
A compact drone under a hull, jetty or into a canal in minutes — to decide whether a dive team is even needed.
Blueye X3 Ultra →I need to recover an object
Evidence, a weapon or ordnance brought up with a manipulator — keeping the item, and the officer, intact.
SEAMOR Chinook →The water is black or fast
Zero visibility, strong current or contaminated water where a diver would be slow, unsafe or blind.
Tethys One →I need to stay covert (EMCON)
No tether signature, no host vessel pinned on station — quiet work in sensitive or contested water.
BeeX HAUV → · Hydromea ExRay →I'm inspecting a confined space
Flooded voids, tanks, J-tubes and tight clearances where a tether would snag and a larger vehicle can't fit.
Hydromea ExRay →I'm clearing or surveying mines
Wide-area detection, re-acquisition, diver search and acoustic disposal — the full detect-classify-dispose chain.
MCM & EOD mission →Most of these are proven in commercial service
Several of these platforms earn their keep every day in commercial inspection and survey work. That dual-use base means mature, in-production technology — and a deeper spares and training pool behind every defence delivery.
Not sure which platform? Ask.
Tell us the mission, the water and the constraints — we'll recommend the platform or the mix, and send the datasheets. You'll normally have a reply within one business day.
