RDI Overview

Day 71 (May 9, 2026)

RDI unchanged at 62.3% (4th consecutive day). Distance: 2.7 pts. MC: mean 62.06%, CI [58.6, 65.4], P(≥65%)=7.4%. Variables unchanged (awaiting CIA impact decision). "Ceasefire under fire" — US disabled 3 tankers, blocked 70+. Iran attacked 3 US destroyers. UAE reports 2,800+ projectiles intercepted. Israel struck Beirut suburbs (17 killed). WSJ: secret Israeli base in Iraq. Both sides package offensive action in defensive language.

Ceasefire Under Fire: Hormuz Control and Will Erosion

Center of gravity shifted from infrastructure bombing to maritime coercion. CENTCOM: 70+ tankers blocked, 166M barrels, $13B+. Three tankers disabled this week (precision bombs in smokestacks — controlled coercion, not maximum destruction). Iran attacked 3 destroyers (no damage). UAE: 551 ballistic, 29 cruise, 2,263 UAVs intercepted total (13 killed, 230 injured). Israel struck Lebanon (17 killed). WSJ: secret Israeli base in Iraqi desert. Guardian: "Neither the US nor Iran can sustain this indefinitely." The war has entered a phase where "ceasefire" means managing limited strikes and eroding political will — not peace.

Key Events

Tier 1 and 2
Blockade Continues: 3 Tankers Disabled, 70+ Blocked
Tier 1 (CENTCOM, Reuters, AP)

Hasna (May 6), Sea Star III + Sevda (May 8). Not sunk — controlled coercion. 166M barrels/$13B+. Oil slick near Kharg observed but unconfirmed link.

Iran Attacked 3 US Destroyers in Hormuz
Tier 1 (CENTCOM, AP, CBS)

Missiles, drones, fast boats. No US damage. US struck Iranian facilities. Iran: 10 wounded, 5 missing (Mehr ×0.75).

UAE: Total 551 Ballistic, 29 Cruise, 2,263 UAVs
Tier 1 (UAE MoD)

13 killed, 230 injured total. 2,800+ projectiles fired at UAE.

Israel Strikes Beirut (17 Killed) + Secret Iraq Base
Tier 1 (Reuters, AP, WSJ)

Saksakieh: 7 killed (1 child). WSJ: pre-war secret base in Iraqi desert for logistics and special ops.

Fleet & Maritime Ops

US Naval Order of Battle in CENTCOM

3 CSGs (largest since 2003): Lincoln (Arabian Sea), Bush (Gulf of Oman), Ford (Med, returning). 200+ aircraft, 15,000 sailors.

16+ Arleigh Burke destroyers with Aegis. Mason and Truxtun entered Hormuz.

2 ARGs: Tripoli (in theater) + Boxer (en route).

Mine countermeasures (CRITICAL VULNERABILITY): Of 3 MCM LCS, 2 are in Singapore. Only Canberra remains (location unknown). 2 Avengers dispatched from Japan, not yet arrived. Iran has confirmed mines in Hormuz. NAVCENT warned transit is "extremely hazardous."

Total force: 60,000+. 12 F-22s at Ovda (Israel). 14 tankers at Ben Gurion.

Diego Garcia & MV Ocean Trader (Special Operations Mothership): Sentinel-2 imagery (May 8, MT Anderson analysis) shows MV Ocean Trader anchored inside Diego Garcia lagoon alongside USNS Pililaau, at least one Arleigh Burke destroyer, and additional support traffic. Ocean Trader is a 193m converted cargo ship ($73M Maersk refit 2013): SOF command center (40 intel + 20 comms), helicopter hangar, Zodiac/jet ski bays, diving bay for 60 SEALs, medical facility, quarters for 209 (50 crew + 159 SOF), 6x .50-cal guns, FLIR thermal imaging. Speed 20kts, range 8,000nm, 45-day endurance. Operates without AIS ("ghost ship"). Previously deployed Caribbean/Venezuela (2025), now within operational reach of Iranian, Yemeni and Somali coasts. Iran fired 2 ballistic missiles at Diego Garcia in March 2026 (both intercepted/failed). (Tier 1, Army Recognition, Task & Purpose, Janes)

USS Canberra (LCS-30): Last known to be operating in Arabian Sea (USNI News). Only remaining MCM ship in region. May be operating near Diego Garcia given proximity. (Tier 2, inferred from location)

No changes (4th day). CIA warning active. If 70-75% capability confirmed, reassessment needed.

Threshold

Command ✅ Military >60% ✅ Economic ✅

Elite Fracture ✅ Intl Pressure ✅ Proxy ✅ Revolt ❌

Coup ❌ Flight ❌ Ground ❌

CIA warning: "military >60%" may need reassessment. 50+ point gap between CIA and Trump claims.

FARAJA Analysis

Structural Destruction Levels

Level 1: 5/6 national HQs destroyed. Level 2: 4/11 provincial HQs hit. Level 3: 21/86+ stations hit (15+ Bellingcat confirmed). Command shifted to "board model" + autonomous regional HQs designed by Larijani.

IRGC & Basij

Force Status

Vahidi is de facto ruler (ISW confirmed). Pezeshkian marginalized. UAE attack done without president. Imam Ali battalions paralyzed. 8-10/23 Basij bases destroyed. Qaani warned Iraqi militias of "real dangers" (April 18).

Supply Chain

Raw Materials, Assembly, Deployment

Raw materials: disrupted (blockade). Assembly: paralyzed but CIA says repair/new assembly started. Deployment: 29/30 launch bases struck, ~350/470 launchers destroyed — but CIA says 75% mobile launchers remain. 50+ point gap with Trump.

Scenarios

40-50%
Incomplete Deal
25-35%
Phase 2 Bombing
15-25%
Armed Deadlock

6 days to Trump-Xi (May 15). Clock ticking, bombs in smokestacks.

FARAJA Analysis

Level 1: Board model governance. Mojtaba incapacitated (NYT). Vahidi de facto ruler (ISW). Pezeshkian sidelined.

Level 2: 4/11 regional HQs struck. No confirmed reconstruction.

Level 3: 21/86+ stations hit (15+ Bellingcat confirmed). CIA claims underground recovery but for missiles, not FARAJA.

IRGC/Basij

Imam Ali battalions: paralyzed. Bayt al-Moqaddas: under pressure. 8-10/23 Basij bases destroyed. IRGC operationally active in Hormuz but at fraction of capacity (6 boats vs 20-40). Larijani new structure: autonomous regional HQs (coup-proofing).

Supply Chain

Raw materials: Disrupted. Blockade limits imports. Oil smuggling via Central Asian rail possible but low volume.

Assembly: Paralyzed. CIA says "near-complete missiles assembled" but from pre-war stock. Main facilities non-operational.

Deployment: Severely damaged. 29/30 launch bases struck. ~350/470 launchers destroyed. CIA claims 75% retained vs Trump's 18-19%.

Conclusion

Day 71: war changed shape but hasn't ended. From city bombing to maritime coercion. Key technical finding: US mine countermeasure weakness — 2 of 3 ships in Singapore while Iran has mined Hormuz. If a commercial ship hits a mine, crisis escalates from "ceasefire under fire" to "maritime disaster." Question: does Iran respond to MOU before May 15?

Limitations

Tanker strikes confirmed but damage details unverified. Hormuz exchange from CENTCOM only. UAE figures from UAE MoD. Iran casualties from Mehr (×0.75). Oil slick unconfirmed link. Iraq base (WSJ) is disclosure not official. CIA assessment pending. All party claims ×0.75.
