Amphibious Assault Forces Drone Guide

By Association for Drones

Published

Amphibious forces are military organisations designed to operate across the maritime and land environments, traditionally using ships, landing craft, helicopters, aircraft, and specialised ground vehicles to move personnel and equipment between sea and shore. Modern amphibious operations are increasingly multi-domain, involving maritime, land, air, space, cyber, communications, intelligence, and logistics capabilities.

Drone technology is becoming an important part of this wider ecosystem.

Uncrewed aerial vehicles (UAVs), uncrewed surface vessels (USVs), and uncrewed ground vehicles (UGVs) can provide amphibious forces with additional reconnaissance, mapping, communications, logistics, environmental assessment, and situational-awareness capabilities. Military organisations already use UAS extensively for intelligence, surveillance and reconnaissance (ISR), communications relay, and logistics-related functions.

For amphibious organisations, drones are particularly interesting because operations often involve large distances, rapidly changing coastal environments, limited infrastructure, and the need to connect forces operating at sea with personnel and equipment ashore.

This guide provides a general, non-tactical overview of how drone technology can support amphibious forces, rather than instructions for conducting combat operations.

The Amphibious Operating Environment

Coastal environments are among the most complex areas in which drones can operate.

The transition between sea and land introduces beaches, cliffs, ports, rivers, wetlands, islands, urban waterfronts, changing tides, waves, wind, saltwater, and rapidly changing weather.

Amphibious forces may also operate considerable distances from established land-based infrastructure.

Drones provide a flexible means of collecting information across these environments without requiring crewed aircraft or personnel to physically access every location.

Different types of uncrewed systems can also work across different domains.

Uncrewed Aerial Vehicles

UAVs provide the aerial component of an uncrewed amphibious capability.

Aircraft can range from small multirotor drones used for local observation to fixed-wing and VTOL systems capable of covering much larger areas.

Depending on the platform, UAVs can carry high-resolution RGB cameras, thermal cameras, LiDAR, Synthetic Aperture Radar (SAR), multispectral sensors, environmental instruments, communications equipment, or other specialised payloads.

Larger ISR UAVs can provide persistent surveillance across extensive land and maritime areas; NATO, for example, operates remotely piloted aircraft equipped with SAR that provide long-range, day/night and all-weather surveillance capabilities.

Uncrewed Surface Vessels

Uncrewed Surface Vessels operate on the water rather than in the air.

These systems can potentially support maritime surveying, environmental monitoring, communications, logistics, hydrographic data collection, and situational awareness.

USVs may carry cameras, radar, sonar, meteorological sensors, communications equipment, or other payloads.

Combining aerial and surface drones provides organisations with information from two very different perspectives.

Uncrewed Ground Vehicles

Once ashore, uncrewed ground vehicles provide another potential layer of capability.

UGVs can be designed to transport equipment, carry sensors, inspect infrastructure, perform engineering-related tasks, or operate in environments considered unsuitable for immediate personnel access.

For amphibious organisations, the longer-term development of integrated aerial, maritime, and ground robotics is particularly significant.

Instead of viewing each drone as an independent system, future forces are likely to operate networks of interconnected uncrewed platforms.

Intelligence, Surveillance and Reconnaissance

ISR remains one of the most established applications for military UAVs.

Drone sensors can provide imagery and other remote-sensing information that contributes to a broader understanding of coastal environments.

High-resolution cameras provide visual information, thermal sensors detect temperature differences, LiDAR produces three-dimensional measurements, and SAR can provide radar imagery independent of visible daylight.

Information from these systems can be combined with satellite imagery, crewed aircraft, maritime sensors, maps, and other authorised information sources.

The objective is to provide decision-makers with improved situational awareness.

Coastal Mapping

Accurate geographic information is particularly valuable around coastlines because conditions can change substantially over relatively short periods.

Drone photogrammetry can produce detailed orthomosaic imagery and three-dimensional models of coastal areas.

LiDAR can provide highly accurate measurements of terrain, cliffs, dunes, vegetation, infrastructure, and other features.

These datasets can support general geographic understanding, environmental monitoring, infrastructure assessment, training and planning.

Repeated surveys also allow organisations to compare how an environment changes over time.

Synthetic Aperture Radar

Synthetic Aperture Radar provides an important capability for larger uncrewed aircraft.

Unlike conventional cameras, SAR uses radar signals rather than visible light.

This means it can collect information during both daytime and darkness and under some conditions involving cloud, haze, or poor visibility.

SAR is particularly useful for large-area surveillance and remote sensing. NATO’s ISR force, for example, uses RQ-4D aircraft equipped with SAR for persistent surveillance across land and maritime environments.

Future smaller SAR payloads could extend similar remote-sensing concepts to more compact UAV platforms.

Thermal Imaging

Thermal cameras measure infrared radiation associated with surface temperature.

For amphibious forces, thermal imaging can support general situational awareness, infrastructure assessment, search and rescue, disaster response, and night-time observation.

Thermal sensors are particularly useful when combined with high-resolution RGB cameras.

The RGB sensor provides familiar visual information while thermal imagery provides an additional layer of environmental information.

Maritime Situational Awareness

Understanding activity across coastal waters is important for organisations operating between ships and shore.

Drones can contribute imagery and sensor information that complements ship-based radar, Automatic Identification System information, satellites, maritime patrol aircraft, and other surveillance systems.

Uncrewed aircraft can provide a different viewing perspective from ship-mounted sensors.

USVs can simultaneously collect information from the surface.

Combining these datasets creates a more complete maritime picture.

Communications Relay

Communications are particularly challenging when personnel, vessels, vehicles, and aircraft are distributed across large maritime and coastal areas.

UAVs can potentially operate as airborne communications relays.

An elevated communications platform can help extend connectivity between geographically separated authorised users, depending on the communications architecture being employed.

Communications relay is already recognised as an established military UAS role.

Future systems may increasingly use interconnected drone networks rather than relying on individual aircraft.

Logistics and Resupply

Logistics is one of the most demanding aspects of amphibious operations because personnel and equipment may initially depend heavily on resources transported from ships offshore.

Uncrewed systems offer another potential transportation method.

Cargo drones can transport relatively lightweight equipment between suitable locations, while larger autonomous aircraft may eventually carry significantly heavier loads. UAS cargo and resupply is already an established area of military development.

Uncrewed surface vessels could provide another logistics layer for moving suitable supplies across water.

Ground robots could subsequently transport equipment after reaching shore.

Search and Rescue

Amphibious organisations also conduct training, humanitarian, disaster-response and emergency operations where search and rescue capabilities are important.

Drones equipped with RGB and thermal cameras can support searches across coastal environments, islands, beaches, cliffs, and open terrain.

Aerial imagery can also help rescue coordinators understand environmental conditions and access routes.

USVs may complement aerial systems by providing information from the water.

Humanitarian Assistance and Disaster Response

Amphibious ships and forces are frequently capable of supporting humanitarian and contingency operations because they combine transportation, aviation, logistics and medical capabilities. The U.S. Navy specifically notes the role of amphibious ships in humanitarian and other contingency missions.

Drones can expand these capabilities.

Following hurricanes, tsunamis, earthquakes, floods, or severe storms, UAVs can rapidly survey affected coastal communities.

They can document damaged roads, bridges, ports, buildings, hospitals, utilities, and other infrastructure.

Cargo drones may also provide an additional method of transporting lightweight emergency supplies to isolated communities.

Infrastructure Assessment

Ports and coastal infrastructure can suffer extensive damage following natural disasters or severe weather.

Drone imagery allows engineering teams to conduct initial visual assessments of ports, bridges, roads, communications infrastructure, buildings, seawalls, and other assets.

LiDAR and photogrammetry can subsequently create three-dimensional models for more detailed assessment.

This information can be incorporated into GIS and engineering systems.

Multi-Sensor Drone Payloads

Modern drone platforms increasingly carry more than one sensor.

A sophisticated payload might combine:

  • High-resolution RGB imaging
  • Optical zoom
  • Thermal imaging
  • LiDAR
  • Synthetic Aperture Radar
  • Multispectral imaging
  • Environmental sensors
  • Accurate GNSS/RTK positioning
  • Communications equipment

Different sensors provide different types of information.

Combining them creates a more comprehensive understanding than relying on a single camera.

Artificial Intelligence

Artificial intelligence is becoming increasingly important because drone fleets can generate enormous quantities of data.

AI can assist with image organisation, mapping, object classification, change detection, sensor-data fusion and highlighting information for human review.

Rather than requiring personnel to manually examine every image collected during a large survey, automated systems can help organise and prioritise information.

Human oversight remains important, particularly where information contributes to significant operational decisions.

Data Fusion

Future amphibious drone operations will increasingly depend on combining information from multiple systems.

Aerial drones, surface vessels, ground robots, satellites, ships, aircraft, environmental sensors and other information sources can all contribute data.

Digital platforms can combine these datasets into a common operating picture.

This transition from individual drones towards connected sensor networks represents one of the most important developments in uncrewed technology.

Challenges of Maritime Drone Operations

Operating drones around the sea presents significant technical challenges.

Saltwater is highly corrosive, while sea spray can affect electronics and optical sensors.

Strong coastal winds can reduce endurance and flight stability.

Communications become increasingly challenging as distances from ships increase, and moving vessels create additional complexity for launch and recovery.

GNSS reliability, electromagnetic environments, weather, battery endurance and payload weight must also be considered.

Platforms intended for sustained maritime operation therefore require appropriate environmental protection and robust communications.

Different Drone Types

No single drone design is suitable for every amphibious application.

Multirotor aircraft provide precise hovering and vertical take-off but generally have shorter endurance.

Fixed-wing drones provide significantly greater range and endurance but traditionally require more space for launch and recovery.

Hybrid VTOL aircraft combine vertical take-off with efficient fixed-wing flight.

Uncrewed surface vessels provide greater endurance on water, while UGVs provide mobility after reaching land.

The future is therefore likely to involve combinations of different platforms rather than one universal system.

The Future of Amphibious Drone Technology

Amphibious forces are likely to become increasingly connected with autonomous and remotely operated systems.

Future fleets could combine UAVs, USVs and UGVs operating within shared digital networks.

Larger UAVs could provide wide-area surveillance, while smaller aircraft conduct local mapping or inspection. Surface drones could provide maritime sensing and logistics, while ground robots provide transportation and engineering support ashore.

Artificial intelligence will increasingly help manage these fleets and process the information they collect.

Advances in satellite communications, mesh networking, edge computing, autonomous navigation, sensor miniaturisation and battery technology will further increase operational flexibility.

Digital twins could also allow coastal environments, ports, infrastructure and other areas to be represented within detailed virtual environments incorporating continuously updated sensor information.

Conclusion

Drone technology is becoming an important part of the broader technological transformation of amphibious forces.

UAVs can provide aerial imagery, mapping, remote sensing and communications capabilities. Uncrewed surface vessels can support maritime sensing and logistics, while ground robots can provide additional capabilities ashore.

The greatest development is likely to be the integration of these systems.

Rather than operating a single drone independently, future amphibious organisations are likely to manage interconnected networks of aerial, maritime and ground robots alongside ships, aircraft, satellites and personnel.

Applications extend beyond combat operations to include training, search and rescue, disaster response, humanitarian assistance, environmental monitoring, logistics, infrastructure assessment and communications.

Important challenges remain, including saltwater exposure, weather, communications, endurance, navigation, cybersecurity, interoperability and the need for effective human oversight.

However, continuing developments in artificial intelligence, autonomous navigation, SAR, LiDAR, thermal imaging, communications, robotics and multi-domain networking are rapidly expanding what uncrewed systems can provide.

For navies, marine forces, coast guards, disaster-response organisations and other organisations operating across the sea-to-land environment, drones are developing into an increasingly important component of modern amphibious capability.
