Question 1

What are drone counter-measures?

Accepted Answer

Drone counter-measures — also called counter-UAS (unmanned aircraft systems) — are layered detection and mitigation capabilities designed to identify, track, and neutralise unauthorised aerial threats including surveillance drones, payload-bearing platforms, and hostile reconnaissance assets. Mission Support deploys RF, radar, acoustic, and EO/IR detection systems paired with lawful, environment-appropriate mitigation.

Question 2

How does Mission Support detect unauthorised drones?

Accepted Answer

Mission Support uses a multi-modal detection approach: RF spectrum monitoring detects operator-to-drone control links; radar tuned for small-RCS Class I and II UAS provides range and track; acoustic sensor arrays detect low-altitude targets by sound signature; and electro-optical / infrared (EO/IR) systems provide visual confirmation and classification. Sensor fusion correlates data across modalities to reduce false positives.

Question 3

Can counter-UAS capability be deployed for a single event?

Accepted Answer

Yes. Mission Support deploys counter-UAS for both fixed sites and time-limited operations — high-profile events, diplomatic conferences, and executive gatherings with elevated threat profiles. Each deployment begins with a site survey, threat assessment, and regulatory review. Configuration is fitted to the environment and threat picture, not drawn from a standard kit list.

Question 4

Is active counter-drone technology legal to deploy?

Accepted Answer

Active drone mitigation measures are subject to jurisdiction-specific regulation. Mission Support conducts a regulatory review as part of every engagement and only deploys mitigation options lawfully authorised in the relevant territory. We will advise clearly on what is and is not permissible in a given jurisdiction before any deployment.

Question 5

What is RF drone detection and how does it work?

Accepted Answer

RF (radio frequency) detection passively monitors the electromagnetic spectrum for the control and telemetry links between a drone operator and the drone. Most commercial UAS communicate on known frequency bands — 2.4GHz, 5.8GHz, or proprietary protocols — allowing RF sensors to detect the presence of active control links, estimate direction of origin, and in some cases identify the drone model from its RF signature. RF detection is passive — no emissions — making it suitable for covert counter-UAS operations. Limitations: autonomous drones operating without a live control link produce no RF signature, requiring additional detection modalities.

Question 6

What is the difference between counter-UAS and counter-drone?

Accepted Answer

Counter-drone and counter-UAS (Unmanned Aircraft Systems) refer to the same discipline — the capability to detect, track, identify, and where authorised mitigate unauthorised aerial threats. 'Counter-UAS' is the preferred military and governmental term, aligned with NATO doctrine. 'Counter-drone' is the common civilian and commercial term for the same capability. Mission Support operates across both military-standard and civilian regulatory environments and uses the terminology appropriate to the client and jurisdiction.

Question 7

How does a site survey for counter-UAS work?

Accepted Answer

A counter-UAS site survey establishes the physical and electromagnetic baseline of the protected site before any capability is specified. The survey maps the site's RF environment — existing emitters that may mask or interfere with detection systems — and identifies the approach vectors, stand-off distances, and altitude profiles most relevant to the threat. Mission Support conducts site surveys before specifying any detection or mitigation equipment. Sites vary significantly: an urban diplomatic compound has different sensor placement constraints than a rural critical infrastructure node or a temporary high-profile event venue. Capability is fitted to the site, not the reverse.

Question 8

Can drones carry CBRN payloads?

Accepted Answer

Yes. Commercially available UAS have been weaponised with chemical, biological, and radiological payloads in documented real-world incidents. Even small Class I drones are capable of dispersing liquid or powder agents over an area or delivering a package. This threat profile is one reason Mission Support treats counter-UAS and CBRN preparedness as related capability areas: a site facing a drone threat should have CBRN response procedures that account for payload-bearing platforms, not just surveillance drones.

Question 9

What happens after a drone is detected?

Accepted Answer

Detection produces a track — position, heading, altitude, and in some configurations the drone model and operator location. The response depends on the authorised mitigation options for the jurisdiction and site. Options include: alerting on-site security to the drone's position; activating defensive RF disruption if authorised; capturing the drone physically for forensic exploitation; coordinating with law enforcement for operator location and prosecution; or in permissive environments, escalating to kinetic response. Mission Support designs the full detection-to-response workflow — not just the sensor layer — as part of every counter-UAS programme.

Question 10

How does counter-UAS integrate with existing physical security operations?

Accepted Answer

Counter-UAS is most effective when integrated into the site's existing security management structure, not operated as a standalone system. Mission Support wires counter-UAS into the site's command-and-control architecture: drone tracks feed the site security operations centre on the same screen as CCTV, access control, and perimeter sensor feeds. Alert thresholds, response protocols, and escalation procedures are written into the site's security plan and exercised alongside physical security drills. Isolated counter-UAS equipment without integration into the wider security picture produces delayed response and coordination failures.

Question 11

What is counter drone monitoring?

Accepted Answer

Counter drone monitoring is the persistent, real-time observation of the airspace above and around a protected site for unauthorised UAS activity. Unlike single-event deployments — sensors activated for a specific operation or gathering — counter drone monitoring operates continuously, typically in a security operations centre (SOC) configuration where drone tracks appear alongside CCTV, perimeter sensor, and access-control feeds on a unified display. Mission Support provides counter drone monitoring as both a managed service and as an integrated capability within a client's existing physical security management structure. Continuous monitoring is required for sites where the drone threat is standing: diplomatic missions in elevated-threat postings, critical infrastructure facing persistent adversary intent, and executive residences subject to directed aerial surveillance.

Question 12

What is UAS detection?

Accepted Answer

UAS detection — unmanned aircraft system detection — is the capability to identify, locate, and track unauthorised drones in the airspace around a protected site. Mission Support's UAS detection architecture uses multiple complementary sensors: RF spectrum monitoring detects operator-to-drone control links; radar tuned to the small radar cross-section of Class I and II UAS provides range and altitude; acoustic sensor arrays detect low-altitude targets by propeller sound signature; and electro-optical/infrared (EO/IR) systems provide visual classification and tracking. Each modality has distinct performance limits — RF is covert and provides operator-location data; radar provides range and altitude in open environments; acoustic is effective at short range in low-ambient-noise settings; EO/IR is the classification and evidence-capture layer. Sensor fusion across modalities reduces false positives and produces a more reliable track than any single technology alone.

Question 13

How are drone detection and mitigation integrated in a counter-UAS programme?

Accepted Answer

Drone detection and mitigation are the two operational phases of a counter-UAS programme — and their integration determines whether the programme produces outcomes or produces detections that no one can act on. Detection using RF, radar, acoustic, and EO/IR sensors produces a drone track: position, heading, altitude, and in some configurations the operator's ground-station location. Mitigation translates that track into an authorised response. Mission Support integrates detection and mitigation through a designed response workflow: alert thresholds trigger specific response protocols, mitigation options are pre-authorised to match the jurisdiction and the client's legal authority, and the response is executed through the site's security command structure rather than as a parallel system. Detection capability without an authorised, exercised mitigation response is sensor installation — not a counter-UAS programme.
