Deployment Assessment: Port Sudan New International Airport

Site Overview

Port Sudan New International Airport (CIDE-SD-TRANS-00003) is Sudan's primary functioning international gateway, operating under the Transportation Systems sector. Located in Port Sudan — the Red Sea coastal city that has served as Sudan's de facto administrative capital since the fall of Khartoum to RSF forces in March 2025 — the airport carries outsized strategic weight relative to its physical footprint. It is the principal entry and exit point for humanitarian logistics, diplomatic personnel, military resupply, and commercial aviation serving a displaced national government. With 476,500 people within a 25 km radius and the airport functioning as a lifeline node for a country in active civil war, operational disruption here carries consequences that extend well beyond normal transport sector parameters.

The airport sits in a confirmed conflict zone. Despite zero ACLED-recorded incidents within 50 km of the site at the time of this assessment, the broader Sudanese conflict — now in its third year — has demonstrated a consistent pattern of infrastructure targeting, drone employment by both the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF), and episodic strikes on previously "quiet" rear-area nodes. Port Sudan itself sustained drone strikes in May 2025, including hits on the fuel storage facility adjacent to the port and on the city's power infrastructure, marking a significant escalation in RSF reach into what had been treated as a secure rear area. The airport's zero-incident record should be read as a temporary condition, not a structural one.

CARVER Analysis

Composite CARVER: 37/50 — this is a high-priority target by any standard analytical framework.

Component	Score	Interpretation
Criticality	8	National and international aviation hub; no functional substitute within Sudan
Accessibility	4	Restricted airside; large, porous landside perimeter
Recuperability	3	Rapid recovery capability noted — runway repair and system redundancy reduce long-term denial potential
Vulnerability	5	Hardened core systems, but exposed runways, taxiways, and fuel infrastructure
Effect	8	National/international travel disruption; humanitarian logistics cascade; economic and diplomatic impact
Recognizability	9	Universally identifiable; prominent landmark; no ambiguity in targeting

The Recognizability score of 9 is operationally significant. In the current conflict environment, where RSF has demonstrated the ability to conduct long-range drone strikes using commercial and modified FPV platforms, a universally identifiable target with a CARVER composite of 37 and zero confirmed C-UAS deployments represents a material gap between threat exposure and defensive posture.

The Recuperability score of 3 is the single factor moderating the overall risk picture. Runway infrastructure can be repaired; the more durable risk is the chilling effect on flight operations — humanitarian, commercial, and diplomatic — that even a single successful strike would produce.

DRES Assessment

DRES Composite: 6.7 (MEDIUM)

The composite score masks significant sub-score variance that is analytically important:

• Subsurface: 11.5 — the highest sub-score in the profile, reflecting vulnerability to ground-emplaced devices, tunneling, or subsurface infrastructure disruption. In a port-adjacent environment with active conflict, this is not a theoretical concern.
• Ground: 8.2 — consistent with the large landside perimeter noted in the CARVER accessibility assessment. Ground-based intrusion, vehicle-borne threats, and perimeter breach are the dominant near-term vectors.
• Target Profile: 8.15 — the airport presents a high-value, high-visibility profile to adversarial planners. Combined with Recognizability of 9, this confirms the site is on any competent threat actor's target list.
• Hardening: 11.49 — the hardening sub-score is elevated, suggesting existing physical security infrastructure. However, hardening scores in DRES reflect passive and structural measures; they do not account for the absence of active counter-drone or autonomous surveillance systems.
• Air: 4.2 — the air threat sub-score is moderate, not high. This may reflect the current assessed capability ceiling of RSF drone operations at this range, but the May 2025 Port Sudan strikes demonstrate that the air threat envelope is expanding. A 4.2 air score should be treated as a floor, not a ceiling.
• Surface: 2.5 — lowest sub-score; maritime and surface approach vectors are assessed as lower priority given port security infrastructure.

The divergence between the elevated Ground (8.2) and Subsurface (11.5) scores and the moderate Air (4.2) score suggests current defensive investment, if any, is oriented toward the wrong threat vector for the next 12–24 months. The air threat is the fastest-moving variable in this environment.

Verified Deployments

No verified autonomous or robotic system deployments are recorded for this site.

This is a primary finding of this assessment, not a data gap. For a site with a CARVER composite of 37, a confirmed conflict zone designation, a Target Profile sub-score of 8.15, and a Recognizability score of 9, the absence of any publicly evidenced C-UAS, perimeter surveillance robotics, or autonomous FOD detection system represents a structural defensive deficit. The Robotics Gap is formally classified as UNKNOWN — meaning neither confirmed deployment nor confirmed absence of classified/undisclosed systems can be established from open sources.

What is not deployed (no public evidence):

• Counter-UAS systems (RF jamming, kinetic defeat, directed energy)
• Autonomous perimeter surveillance platforms
• Runway FOD detection robotics
• AI-enabled airspace monitoring

What the absence implies: Any operator, program manager, or grant applicant assessing C-UAS procurement priority for this site is working against a baseline of zero. There is no incumbent system to integrate with, no existing sensor architecture to extend, and no established vendor relationship to leverage. This is a greenfield deployment environment at a high-CARVER site in an active conflict zone — a combination that compresses procurement timelines and elevates the cost of delay.

Threat Exposure: Next 12–24 Months

PRIMARY THREAT VECTOR: Small UAS / FPV drone strike

The May 2025 RSF drone strikes on Port Sudan's fuel and power infrastructure established proof of concept for long-range drone operations targeting this city. The airport was not struck in that sequence, but the operational logic for targeting it is straightforward: disrupting the airport degrades SAF logistics, halts diplomatic traffic, and generates international media coverage — all consistent with RSF information operations objectives.

FPV drones and modified commercial platforms (assessed: DJI-class and Iranian-supplied Shahed derivatives based on regional pattern analysis) are the most probable delivery systems. The airport's large physical footprint and the absence of active air defense in the immediate vicinity make low-altitude ingress feasible.

SECONDARY THREAT VECTOR: Ground perimeter intrusion

The Ground DRES sub-score of 8.2 and the CARVER Accessibility score of 4 (large landside perimeter) are consistent with ground-based intrusion risk. In the current operational environment, this includes both direct assault and emplacement of ground-based IEDs or loitering munitions pre-positioned within the perimeter.

TERTIARY THREAT VECTOR: Subsurface infrastructure disruption

The Subsurface DRES score of 11.5 is the highest in the profile. Fuel lines, electrical conduits, and communications infrastructure running beneath the airfield are vulnerable to targeted disruption. This vector is lower probability in the near term but higher consequence if executed.

Procurement and Investment Implications

For infrastructure operators, defense program managers, and FEMA C-UAS grant applicants assessing this site:

Immediate priority (0–6 months): Deployable, rapidly-installable RF detection and jamming capability covering the airport's approach corridors. Given the conflict zone status and absence of any baseline system, the procurement case does not require extended justification — the CARVER composite of 37 and the May 2025 Port Sudan strike precedent are sufficient. Systems with rapid deployment profiles (vehicle-mounted or containerized) are preferred over fixed infrastructure given the operational environment's instability.

Near-term priority (6–18 months): Autonomous perimeter surveillance — ground-based UGV or fixed-sensor networks covering the landside perimeter. The Ground sub-score of 8.2 and the large perimeter footprint make human-only patrol coverage operationally insufficient at current threat levels.

Medium-term priority (12–24 months): Runway FOD detection automation. Perimeter surveillance, runway FOD detection, and security robotics are all identified as applicable use cases (Robotics Relevance score: 7). In a high-tempo operational environment with degraded maintenance capacity, FOD-induced runway closures are a non-kinetic threat to operational continuity that autonomous detection directly mitigates.

Investor and dual-use note: The combination of greenfield deployment status, high CARVER score, active conflict zone designation, and a site serving as a national government lifeline creates procurement urgency that is not present at comparable airports in stable environments. Vendors with deployable, conflict-hardened systems and experience operating under humanitarian or military logistics frameworks are best positioned. The absence of an incumbent creates no integration constraint — but also no existing budget line or contracting vehicle to leverage.

Summary Assessment

Port Sudan New International Airport is a CARVER-37 transport node operating in an active conflict zone with zero verified autonomous system deployments. The May 2025 drone strikes on adjacent Port Sudan infrastructure have closed the gap between theoretical threat and demonstrated capability. The site's Recognizability score of 9 and Target Profile of 8.15 confirm it is a high-priority target for adversarial planners. The absence of C-UAS or autonomous surveillance systems at this site is the central finding of this assessment. Procurement action in the 0–12 month window is warranted; delay increases exposure as RSF drone operational range and targeting sophistication continue to develop.

---

Confidence: MODERATE — CARVER and DRES scores are well-supported by site characteristics and regional conflict data. Deployment absence is confirmed by open-source review but cannot exclude classified or undisclosed systems. Air threat trajectory is directional given the May 2025 strike precedent; specific RSF drone capability assessments carry inherent uncertainty.
