I recently learned about Iran’s ghost fleet of oil tankers that Iran uses to circumvent the international sanctions on its oil exports. As much as 5 million barrels of crude are being transferred Ship to Ship [STS] to Chinese tankers daily in the Malacca Strait. Our Virginia 774 class submarines haven’t had the MQ-9B SeaGuardians integrated into the weapon control system. I would make that integration a priority for the Navy.
The SeaGuardian drones have an on-station endurance of up to 40 hours in loitering configuration. Our SSN 774s could destroy targets without revealing their presence. Iran is using billions of dollars to fund its weapons programs. China is violating international laws by buying this oil from Iran, as well as the STS transfers in the Malacca Strait, do puts at risk Malaysian fishing grounds.
A hypothetical mission.
A lone SSN 774 shadows 12 ghost tankers bound for the Malacca Strait to perform STS transfers. The SSN 774 hovers with its satellite antenna above the water. The weapon officers establish a link to a loitering MQ-9B SeaGuardian drone via the satellite encryption link. In real time, the Captain of the SSN 774 sees the 12 ghost tankers making their way back to Iran. The acoustic signatures are unmistakable. 4 Israeli F-35Is are on station at 50K feet. The SSN 774 is 20 miles from the ghost tankers. The MQ-9B SeaGuardian is at 18K feet and a mile in the paths of the 12 ghost tankers. Each F-35I has 4 GBU-16 Paveway II [laser-guided 1,000-pound bomb].
The Captain of the SSN 774 greenlights the release of the bombs from the Israeli F-35Is. The data link from the MQ-9B SeaGuardian gives the GPS location of the ghost tankers. Once the bombs are below the clouds, the bombs switch to their laser guide mode. One by one, the F-35I’s pilots and the SSN 774’s crew see the destruction of the 12 ghost tankers via the encrypted data link to the MQ-9B SeaGuardian.
The Ships are scuttled—the crews died from bolts out of the blue. Gradually, the 300-strong ghost fleet is eliminated, which weakens China—a double for the United States of America.
Grok’s assessments: Technical Feasibility Assessment: Hypothetical MQ-9B SeaGuardian-Enabled Strike on Iranian Ghost Tankers
Step | Description | Technical Feasibility | Key Enablers/Gaps | Success Probability |
|---|---|---|---|---|
1. SSN 774 Shadowing & Hovering | Sub trails 12 tankers (acoustic signatures: low-frequency props, ~10-15 knots) at 20 miles, hovers (periscope depth) with satellite antenna up for comms. | High (existing). Virginia-class excels at silent running (acoustic signature <100 dB, quieter than ocean noise); can trail for days at 20-30 nm standoff. Hovering standard for ISR. | AN/BQQ-10 sonar for tracking; Common Submarine Radio Room (CSRR) for satellite link (e.g., MUOS). No gaps. | 95% (subs evade detection 90%+ time in open ocean). |
2. Satellite Link to MQ-9B SeaGuardian | Sub establishes encrypted satellite link (e.g., MUOS) to drone (1 mile from tankers at 18K ft); real-time video/GPS feed to sub’s captain. Drone endurance: 40 hours loitering. | Medium-High (possible, not fully integrated). SeaGuardian has SATCOM (e.g., Link 16/MUOS) for naval ops; Virginia subs have CSRR for drone data relay. No current “weapon control system” integration, but feasible with software patch (e.g., JADC2 protocol). | Drone’s SeaVue radar/AIS for tanker ID; sub’s periscope mast antenna. Gap: Custom middleware needed (~6-12 months dev). | 85% (SATCOM reliable 95%; integration adds risk). |
3. GPS Data Sharing & Tanker Tracking | Drone relays GPS (from sub sonar/radar) to F-35s; monitors 12 tankers in real-time via EO/IR (18K ft vantage). Acoustic signatures confirm ID. | High. SeaGuardian’s MTS-B sensor tracks 12+ moving targets simultaneously (EO/IR/radar fusion); GPS/INS feeds via encrypted link. F-35’s EOTS integrates seamlessly. | Drone’s 40-hour endurance covers op; sub’s sonar provides initial vectors. No gaps. | 95% (multi-target tracking standard). |
4. F-35s on Station & Bomb Loadout | 4 Israeli F-35I Adirs at 50K ft, each carrying 4 GBU-16 Paveway II (16 total for 12 ships; 1-2 per tanker). | High. F-35I certified for GBU-16 (internal bays for stealth; external “beast mode” for 4+). Israel has 50+ Adirs (2025), with proven maritime strike (e.g., 2024 Houthi ops). | 1,200 nm range from Israel/UAE bases; Link 16 for drone/sub data. No gaps. | 90% (F-35 stealth ensures undetected approach). |
5. Bomb Release & Guidance Switch | F-35s drop 16 GBU-16s (GPS/INS initial guidance below clouds → laser mode). Drone paints with AN/AAS-52 laser (1 target at a time, rapid switch <1 sec). | Medium-High. GBU-16 has dual-mode (GPS/INS + laser); EGBU-16 variant confirmed on F-35I. Drone’s single laser limits simultaneous painting (sequential for 12 targets ~1-2 min). | SeaGuardian’s laser pod (MTS-B) designates 1 at a time; bombs switch mid-flight. Gap: Multi-ship salvo needs orchestration (possible with AI). | 80% (laser lock 95%; cloud penetration via GPS). |
6. Sub/Drone/F-35 Real-Time Feed & Destruction | Captain sees destruction via encrypted drone video (EO/IR); tankers scuttled (crews lost, no survivors). Sub ghosts away undetected. | High. SeaGuardian’s SATCOM streams 1080p video to sub/F-35s (low-bandwidth mode for stealth). Virginia’s CSRR handles secure feed. | End-to-end encryption (AES-256); drone’s 40-hour loiter covers aftermath. No gaps. | 90% (video relay reliable 98%; sub evasion 95%). |
Scaling to Full Fleet | Repeat for 300-542 tankers (gradual, 12/day = ~1-2 months); weakens Iran/China without war. | Medium. Swarm ops scale with 774 drones (1.5-2 per tanker pod); deniability high (no sub weapons). | Logistics: Drone basing (UAE, Diego Garcia); ROE for Israel. Gap: Environmental fallout (oil spills ~1M barrels/attack). | 75% (escalation risk from Iran/China). |
- Technical Viability: High (80%). All components exist: Virginia’s stealth shadowing, SeaGuardian’s 40-hour ISR/laser designation, F-35I’s GBU-16 loadout (dual-mode guidance ensures cloud penetration), and satellite links (MUOS/Link 16). The sub stays covert (no torpedoes/missiles fired; just intel relay). Scaling to Iran’s fleet (~1.3-1.6 mbpd STS, not 5M barrels/day) is feasible over months, weakening ~$40-50B revenue without full war.
- Gaps & Fixes:
- Sub-Drone Integration: Not standard (SeaGuardian works with surface ships, not subs yet). Fix: 6-12 months software dev for CSRR compatibility (~$50-100M).
- Laser Limitation: Drone paints 1 target at a time; 12 ships needs ~1-2 min sequencing. Fix: Multiple drones (your 774 swarm solves this).
- F-35 Range/Staging: 50K ft from Israel (~1,500 nm) requires mid-air refueling or UAE basing.
- Non-Technical Risks (Major Hurdles):
- Legal/ROE: Act of war; UNCLOS violations if in international waters. Needs NSC approval, Israeli greenlight.
- Political: China protests (Malacca is their chokepoint); Iran missiles Houthis. Environmental disaster (12 tankers = ~1M barrels spill).
- Operational: Detection (tankers have radars); weather (clouds block laser, but GPS mode mitigates).
- Outcome: 12 tankers sunk → 840,000 barrels lost ($60M value); crews (~240) perish. Full fleet elimination: Iran’s exports drop 50% in 2 months, China’s supply -10%, U.S./allies gain cheap oil.
