Analyst Assessment
Verdict
Edge: Sudan
Sudan holds absolute conventional dominance over South Sudan due to its air superiority, mechanized depth, and domestic arms production, though its actual force projection is handicapped by the ongoing RSF insurgency. South Sudan’s military remains a fractured, embargo-crippled light infantry force incapable of sustained external conflict.
Domain by domain
Air Power
Edge: Sudan
🇸🇸 South SudanRotary-wing only (Mi-24); lacks fixed-wing combat aircraft and modern air defense.
Ground Forces
Edge: Sudan
🇸🇩 SudanHeavy armor advantage (224 MBTs), integrating FPV drones for precision strikes.
🇸🇸 South SudanHigh raw manpower (185,000) but poor cohesion, minimal armor (30 MBTs), and ethnic divisions.
Naval
Edge: Sudan
🇸🇩 SudanCoastal fleet on the Red Sea securing deep-water ports and maritime trade.
🇸🇸 South SudanSmall riverine force limited to patrolling the White Nile.
Logistics
Edge: Sudan
🇸🇩 SudanSupported by a domestic military industry (MIC), despite recent war damage.
🇸🇸 South SudanNon-existent domestic production; wholly reliant on illicit networks due to UN embargo.
Wildcards
- Internal Civil Wars Both states are distracted by internal existential threats (SAF vs. RSF in Sudan; SSPDF vs. NAS in South Sudan). A two-front war would rapidly collapse either military's logistical capacity.
- Economic Chokepoints South Sudan’s economy relies almost entirely on oil exported through pipelines running across Sudan. Khartoum can instantly shut off Juba's revenue stream, collapsing its ability to fund its military patronage networks.
- Regional Intervention Ugandan military intervention to stabilize the Juba government, or accelerated Egyptian and Iranian logistical support for Khartoum, could rapidly alter the localized balance of power.
Outlook
| Scenario | Short war | Protracted war |
|---|---|---|
| Conventional | 🇸🇩 Sudan dominates | 🇸🇩 Sudan breaks SSPDF logistics |
| Hybrid/Asymmetric | Even Border skirmishes stall | 🇸🇸 South Sudan fractures internally |
