Joint Staff Chairman Gen. Dan Caine: Trump ‘Operation Epic Fury is approved. No aborts. Good luck.’

Joint Chiefs Chairman General Dan Caine delivered a Pentagon briefing detailing the opening hours of Operation Epic Fury, the large-scale U.S. military operation against Iranian military infrastructure. Caine walked reporters through the precise moment President Trump issued the final go order — 15:38 Eastern on Friday, February 27 — and the synchronized waves of cyber, space, air, and sea operations that followed. In the first 24 hours, the Joint Force struck more than a thousand targets across Iran, disabling command and control nodes, ballistic missile sites, naval forces, and intelligence infrastructure. U.S. Cybercom and Spacecom moved first, blinding Iranian communications and sensor networks before aircraft launched. More than a hundred aircraft — fighters, tankers, airborne early warning, electronic attack planes, bombers, and unmanned platforms — formed a single synchronized wave as dawn crept across the Central Command area of responsibility. Tomahawk missiles from Navy ships struck Iranian naval forces along the southern flank. B-2 bombers flew 37-hour round-trip sorties from the continental United States, dropping precision, penetrating munitions on underground Iranian facilities. Caine confirmed the Joint Force has established local air superiority over Iran roughly 57 hours into the operation, enabling continued strikes. Caine on the go order: “At 1538, 3:38 p.m., on Friday, February 27th, the United States Central Command, through the Secretary of War, received the final go order from President Trump. The President directed, and I quote, ‘Operation Epic Fury is approved. No aborts. Good luck,’ close quote.” On scale: “This was a massive overwhelming attack across all domains of warfare, striking more than a thousand targets in the first 24 hours.”

The Final Go Order

Caine opened the briefing with the precise timestamp. “At 1538, 3:38 p.m., on Friday, February 27th, the United States Central Command, through the Secretary of War, received the final go order from President Trump.”

The specificity matters. Military historians will record this exact moment as the launch of the largest U.S. strike operation against Iran in the 47-year history of the Islamic Republic.

“The President directed, and I quote, Operation Epic Fury is approved. No aborts. Good luck, close quote.”

Three phrases capture Trump’s command style — approval, commitment (“no aborts”), and personal backing (“good luck”). There would be no last-minute recall. The Joint Force received authorization to execute.

Preparation Phase

“In the region, every element of the Joint Force made their final preparations.”

Caine walked through the preparation sequence.

Air defense batteries readied themselves to respond to Iranian attacks. Pilots and crews rehearsed their strike packages. Weapons were loaded. Two carrier strike groups moved toward launching points.

“Across the globe, our operation centers came alive in Tampa, Florida, here at the Pentagon, and of course forward in the Central Command AOR.”

Three operation centers coordinating:

Tampa, Florida (CENTCOM headquarters)
Pentagon (Joint Chiefs and Secretary of War)
Forward in the Central Command area of responsibility

The three-location framework shows the scale. This was not a single-site operation.

Operational Security

“As always, operational security was paramount as we sought to maintain and sustain the element of surprise.”

Surprise preserved despite the massive scale. No advance leaks reached Iran. The Iranian military did not have time to disperse assets or activate contingency plans.

“This operation was highly classified so that at each hour, the enemy would see one thing, speed, surprise, and violence of action.”

The “speed, surprise, and violence of action” framework is a U.S. military doctrine phrase. Three pillars of successful strike operations. All three executed simultaneously against Iran.

Cyber and Space First

“The first movers were U.S. Cybercom and U.S. Spacecom, layering non-kinetic effects, disrupting and degrading and blinding Iran’s ability to see, communicate, and respond.”

Cyber and space operations preceded kinetic strikes. This reflects modern U.S. warfare doctrine — blind the adversary’s sensors and communications first, then strike physical targets.

Non-kinetic effects delivered:

Disruption of Iranian sensor networks
Degradation of command and control
Blinding of communications
Adversary left unable to coordinate

The Cybercom and Spacecom capabilities represent two decades of U.S. investment in information dominance. Iran faced a fully networked opponent while its own network was collapsed.

Air Launch

“At each hour, the beginning of major combat operations, 0-1-15 local Eastern Daylight Time, 9:45 local AM Tehran Time, as dawn crept up across the Central Command AOR, the skies surged to life.”

Launch time: 01:15 Eastern / 09:45 Tehran time. Dawn conditions across the region. The daylight strike reflects Iran’s trigger event rather than U.S. preference for night strikes.

“More than a hundred aircraft launched from land, sea, fighters, tankers, airborne early warning, electronic attack, bombers from the states and unmanned platforms, forming a single, synchronized wave.”

The 100+ aircraft included:

Fighters (F-35, F-22, F-15, F-18)
Tankers (KC-46, KC-135 for refueling)
Airborne early warning (E-3 AWACS)
Electronic attack (EA-18G Growler)
Bombers (B-2 from continental U.S., possibly B-52)
Unmanned platforms (MQ-9 Reaper, others)

“Single, synchronized wave” captures the coordination challenge. Aircraft from multiple bases, multiple services, multiple altitudes, and multiple strike packages arriving simultaneously on target.

Daylight Strike

“This was a daylight strike based on their trigger event conducted by the Israeli Defense Forces, enabled by the U.S. Intelligence Community.”

The daylight timing was driven by IDF trigger event. Israeli Defense Forces conducted some triggering action, U.S. intelligence enabled that action, and the timing forced a daylight U.S. response rather than the more typical night strike.

The U.S.-Israel coordination captured in this single sentence. Intelligence sharing, joint planning, and synchronized operational tempo.

Navy Tomahawks

“The first shooters at sea were Tomahawks, unleashed by the United States Navy, closed in on Iranian naval forces, and began to conduct strikes across the southern flank in Iran.”

Tomahawk cruise missiles launched from U.S. Navy ships. Targets: Iranian naval forces along Iran’s southern flank (Persian Gulf, Gulf of Oman, Strait of Hormuz).

Iran’s naval forces included:

Conventional navy ships
IRGC Navy fast attack craft
Coastal defense missiles
Mine-laying assets
Submarines

Trump had separately claimed “all 32 ships at the bottom of the ocean” in his White House remarks. The Tomahawk strikes would have been the primary mechanism.

Ground Forces

“On the ground, forces fired precision standoff weapons, measured, deliberate, precise, and lethal.”

U.S. Army and Marine Corps assets firing precision standoff weapons. Likely targets:

Iranian missile launch sites within range
Command posts accessible from ground platforms
Air defense installations

“Measured, deliberate, precise, and lethal” — four descriptors emphasizing discipline. This was not indiscriminate bombing.

A Thousand Targets

“This was a massive overwhelming attack across all domains of warfare, striking more than a thousand targets in the first 24 hours.”

Scale comparison:

Desert Storm opening night: ~148 targets
2003 Iraq War opening: ~300 targets
Libya 2011 opening: ~22 targets
Syria 2017 chemical weapons strike: ~59 targets

A thousand targets in 24 hours is an order of magnitude larger than most prior operations. It reflects the scope of Iranian infrastructure requiring neutralization.

57 Hours In

“We are now roughly 57 hours into the operation.”

Caine providing the time marker. Operation Epic Fury ongoing 57 hours after initiation. Not a single strike — sustained combat operations.

Initial Phase Targets

“In the initial phase, CENTCOM’s focus was systematic targeting of Iranian’s Command and Control infrastructure, naval forces, ballistic missile sites, and intelligence infrastructure, designed to daze and confuse them.”

Four target categories in the first phase:

Command and control infrastructure
Naval forces
Ballistic missile sites
Intelligence infrastructure

“Designed to daze and confuse them” — the objective was not merely destruction but disruption. An Iranian leadership unable to understand what was happening or respond coherently.

Cyber and Space Continuing

“Coordinated space and cyber operations, effectively disrupted communications and sensor networks across the area of responsibility, leaving the adversary without the ability to see, coordinate, or respond effectively.”

Cyber and space operations continuing through the strike phase. Not a one-time blinding but sustained disruption. Iranian attempts to restore communications met with renewed attacks.

Local Air Superiority

“The combined impact of these strikes swift, precise, and overwhelming has resulted in the establishment of local air superiority.”

Local air superiority declared 57 hours into the operation. U.S. aircraft can operate over Iran without significant threat from Iranian air defense.

Air superiority enables:

Follow-up precision strikes
Intelligence collection sorties
Special operations support
Combat search and rescue if needed

“This air superiority will not only enhance the protection of our forces, but also allow them to continue the work over Iran.”

“The work over Iran” — continued operations. Not a conclusion but a phase. The operation continues.

Sustained Tempo

“Over the course of the last two days, the Joint Force has launched hundreds of missions from land and sea and delivered tens of thousands of pieces of ordnance. The effort continues to scale.”

Hundreds of missions. Tens of thousands of ordnance pieces. Scaling up, not down.

The sheer volume suggests comprehensive degradation of Iranian military capability. Most analysts have considered Iran’s conventional forces outclassed by the U.S.; Caine’s numbers confirm the gap in practice.

B-2 Bombers

“This included American B-2 bombers, which again, similar to Midnight Hammer, flew a 37-hour round-trip sortie from the continental United States, dropping precision, penetrating munitions on Iranian underground facilities across the southern flank and slightly deeper.”

B-2 stealth bombers from Whiteman Air Force Base in Missouri, round-trip 37 hours. Midnight Hammer was the earlier June 2025 strike on Iranian nuclear facilities using GBU-57 Massive Ordnance Penetrators.

“Precision, penetrating munitions on Iranian underground facilities” — the GBU-57 or successor bunker-buster class. Targets hardened, deeply buried Iranian facilities.

“Southern flank and slightly deeper” — geographic area covered. Iran’s southern coast plus some inland locations.

Significance

Caine’s briefing provided the official military account of Operation Epic Fury’s opening hours. The scope exceeds any prior U.S. strike operation against Iran.

The strategic objectives:

Eliminate Iranian conventional military threat
Disable Iranian command and control
Destroy Iranian naval power
Degrade Iranian missile capability
Establish air superiority for continued operations

The execution demonstrates:

Cross-domain coordination (cyber, space, air, sea, ground)
Precision targeting at scale
Sustainability of sustained combat operations
U.S.-Israel operational integration

The political implications for Trump:

Demonstration of military capability
Fulfillment of Iran deterrence commitment
Global message about U.S. willingness to use force
Regional reshaping of Middle East balance
