Dan Caine.<\/p>\n<p>Those two senior officials supplied updates on <a href=\"https:\/\/defensescoop.com\/tag\/operation-epic-fury\/\" rel=\"nofollow noopener\" target=\"_blank\">Operation Epic Fury<\/a> Wednesday during the first Pentagon press briefing to follow President Donald Trump\u2019s announcement late Tuesday of a two-week ceasefire between the U.S. and Iran.\u00a0<\/p>\n<p>They each broadly quantified the destruction of Iran\u2019s military capabilities over the first five weeks of the war.<\/p>\n<p>\u201cPerhaps most importantly, we\u2019ve destroyed Iran\u2019s defense industrial base and their ability to reconstitute those capabilities for years to come. We attacked, along with our partners, approximately 90% of their weapons factories,\u201d Caine said. \u201cEvery factory that produced Shahed one-way attack drones was struck. Every factory that produces the guidance systems that go into those drones was struck.\u201d<\/p>\n<p>However, some analysts warned it might be too soon to know the full extent of damage and Iran\u2019s potential to rapidly resupply its armory, particularly without the completion of comprehensive combat assessments.<\/p>\n<p>\u201cTreat these figures with real skepticism,\u201d Kelly Grieco, senior fellow at the Stimson Center, told DefenseScoop.<\/p>\n<p>More to the story<\/p>\n<p>Operation Epic Fury has been billed as a U.S.-led, Israel-coordinated military campaign to annihilate Iran\u2019s leadership, ballistic missile and drone capabilities, naval power, manufacturing capacity and nuclear infrastructure, since it was launched by Trump on Feb. 28.<\/p>\n<p>\u201cOver the course of 38 days of major combat operation, the joint force achieved the military objectives as defined by the president,\u201d Caine said on Wednesday.\u00a0<\/p>\n<p>Throughout the war, Iran attacked U.S. military facilities and other targets around the Middle East with deadly drone and missile barrages and disrupted at times nearly all maritime traffic flowing on a major global shipping route and chokepoint for oil near the Strait of Hormuz.<\/p>\n<p>Shortly before the expiration of a deadline set by Trump that <a href=\"https:\/\/defensescoop.com\/2026\/04\/06\/us-deployed-more-than-150-aircraft-rescue-downed-aviator-iran\/\" rel=\"nofollow noopener\" target=\"_blank\">accompanied a threat<\/a> to obliterate Iran\u2019s critical infrastructure, America and Iran agreed to a <a href=\"https:\/\/www.reuters.com\/world\/asia-pacific\/us-iran-ceasefire-what-we-know-2026-04-08\/\" rel=\"nofollow noopener\" target=\"_blank\">two-week ceasefire<\/a> late Tuesday.\u00a0<\/p>\n<p>Brokered by Pakistan, the deal offers a somewhat fragile break in warfare so that deeper negotiations between the nations involved can occur. The ceasefire reportedly includes agreements to suspend strikes in Iran for 14 days and allow for discussions of a settlement that includes nuclear constraints on Iran and sanctions relief, and the opening of the Strait of Hormuz for the entire duration of the truce.<\/p>\n<p>\u201cWe welcome the ongoing ceasefire, and as the secretary said, we hope that Iran chooses a lasting peace,\u201d Caine noted. \u201cBut, as Secretary Hegseth said \u2014 let us be clear, a ceasefire is a pause, and the joint force remains ready if ordered or called upon to resume combat operations with the same speed and precision as we\u2019ve demonstrated over the last 38 days.\u201d<\/p>\n<p>He and Hegseth described how Iran and Israel \u201cdecimated\u201d Iran\u2019s combat power since the start of Epic Fury.<\/p>\n<p>They noted that the U.S. struck 13,000 targets, which included more than 4,000 dynamic targets that Caine said \u201cpopped up on the battlefield and were immediately addressed thanks to the exceptional command-and-control system and intelligence acumen and agility of our joint force.\u201d<\/p>\n<p>U.S. Central Command \u201cdestroyed approximately 80% of Iran\u2019s air defense systems \u2014 striking more than 1,500 air defense targets, more than 450 ballistic missile storage facilities, 800 one-way-attack drone storage facilities \u2014 all of these systems are gone,\u201d Caine said.\u00a0<\/p>\n<p>The top American military general also said the U.S. devastated Iran\u2019s command and control and logistical networks and destroyed more than 2,000 C2 nodes, adding that \u201cit is, and we know this, incredibly frustrating right now to be a lower-level Iranian commander trying to fight your fight.\u201d<\/p>\n<p>Echoing Hegseth\u2019s claims that the Iranian Navy now lies mostly at the bottom of the Arabian Gulf, Caine said the U.S. has assessed that more than 90% of Iran\u2019s regular maritime fleet has now been sunk, and more than 95% of its naval mines have been eliminated.<\/p>\n<p>According to the officials, every factory that produced Shahed one-way attack drones was hit, which should impact Iran\u2019s ability to make these low-cost weapons that it has used during the war and supplied to U.S. adversaries.<\/p>\n<p>Iran\u2019s missile industry \u201cis shattered, with more than 80% of their missile facilities gone as well as their solid rocket motor production capability,\u201d Caine also said.\u00a0<\/p>\n<p>He and Hegseth further estimated that it could take years for Iran to rebuild any major surface combatants, noting that more than 20 naval production and fabrication facilities were damaged or taken out, while nearly 80% of Iran\u2019s nuclear industrial base was hit.<\/p>\n<p>\u201cIn last night\u2019s wave of more than 800 strikes, we finished completely destroying Iran\u2019s defense industrial base, a core pillar of our mission objectives. What little they have left buried in bunkers is all they will have,\u201d Hegseth said. \u201cBut they can no longer build missiles, build rockets, build launchers or build [unmanned aerial vehicles or] UAVs. Their factories have been razed to the ground, set back in historic fashion.\u201d<\/p>\n<p>Responding to questions from DefenseScoop after the briefing on Wednesday regarding the senior U.S. officials\u2019 assertions about wiping out Iran\u2019s military power and capacity, experts suggested that the figures shared seem feasible, though imperfect.<\/p>\n<p>\u201cBecause it\u2019s Gen. Caine, who is and has been pretty measured, I actually think he\u2019s got justification for giving those metrics,\u201d said a former senior defense official who requested anonymity to speak freely. \u201cNow, are they going to be perfect? They\u2019re not. They never will be, but I think they have a pretty good idea of the targets they\u2019ve struck.\u201d<\/p>\n<p>The officials noted that more information will likely follow from Battle Damage Assessments, cyber reviews,\u00a0Munitions Effectiveness Assessments and other evaluations that are conducted in the immediate wake of combat operations.<\/p>\n<p>\u201cSo on the surface of it, I actually think those numbers are reasonable. Of course, what they don\u2019t tell you is the rest of the story, which is, how many drones do they have hidden in mountains still, which is probably thousands? How many suicide boats do they have hidden in caves along the Strait of Hormuz \u2014 hundreds, maybe more?\u201d the former senior defense official said. \u201cSo there\u2019s always going to be a missing component to those numbers.\u201d<\/p>\n<p>In their view, Iran can\u2019t rapidly rebuild its military arsenal in a way that\u2019s going to match America\u2019s conventional capability.\u00a0<\/p>\n<p>\u201cThis is likely to only accelerate their move to drones, cheap drones \u2014 thousands and thousands of cheap drones, suicide boats, mines, and what we would call almost \u2018asymmetric warfare.\u2019 I continue to say that we\u2019re fighting one fight, and Iran is fighting an entirely different one, which is more of an economic war than it has been a conventional military fight,\u201d the former senior defense official told DefenseScoop.<\/p>\n<p>They said they fully expect Iran will turn to Russia and China to figure out the types of capabilities they should rebuild to most threaten U.S. interests, \u201cknowing that they cannot send up airplanes against us and their navy can\u2019t go up against us.\u201d<\/p>\n<p>Hegseth and Caine did not share an update Wednesday on U.S. casualties sustained in Epic Fury to date.\u00a0<\/p>\n<p>According to Navy Capt. Tim Hawkins, U.S. Central Command\u2019s spokesperson, in total 381 U.S. troops were wounded in action as of April 8, with 344 having returned to duty and three currently characterized as seriously wounded.<\/p>\n<p>At least <a href=\"https:\/\/defensescoop.com\/2026\/03\/24\/iran-war-us-troops-wounded-operation-epic-fury\/\" rel=\"nofollow noopener\" target=\"_blank\">13 U.S. military personnel have been killed<\/a>, including six U.S. Army Reserve soldiers who were killed in a drone strike in Kuwait in the early days of the conflict.<\/p>\n<p>\u201cHow could Iran not go out and buy 200,000 more drones or build them, get them in, put even more capabilities on them?\u201d the former senior defense official said. \u201cSo, we\u2019re going to have to come up with drone defenses. Maybe that\u2019s the big piece of this \u2014 yet another wake-up call about the importance of counter-drone systems.\u201d<\/p>\n<p>In a separate conversation with DefenseScoop, Grieco, a senior fellow with the Reimagining U.S. Grand Strategy Program at the Stimson Center and an adjunct professor of security studies at Georgetown University, said the topic of Iran\u2019s capacity to reconstitute its drone arsenal is \u201cwhere [she is] most skeptical of the briefing\u201d on Wednesday.<\/p>\n<p>\u201cThe Shahed drone is intentionally simple \u2014 that\u2019s a design feature, not a limitation. Iran has spent years dispersing its production, relying on dual-use components, and developing supply chains that are difficult to fully map, let alone destroy,\u201d she said. \u201cStriking every known factory is not the same as destroying the capability. If the design files, technical knowledge, and supplier relationships survive, and they almost certainly do, reconstitution is a matter of months, not years.\u201d<\/p>\n<p>Putting it another way, a former defense official said it\u2019s clear that producing Shaheds isn\u2019t hard. The war between Russia and Ukraine has demonstrated how commercial off-the-shelf platforms and services can enable anyone \u2014 bad actors or otherwise \u2014 to operate effectively.<\/p>\n<p>\u201cThe problem with the Iranian regime is their ability to attack a very large surface area with any number of vulnerable targets whether in Iraq, Kuwait, Qatar, UAE, Bahrain, etc. That alone enables the [Islamic Revolutionary Guard Corps or] IRGC to degrade or disrupt the global economy. They can create terror instantly at fairly long ranges and I don\u2019t think there is much we can do to mitigate that in the near term,\u201d the former defense official told DefenseScoop.<\/p>\n<p>\u2018Selling a victory\u2019<\/p>\n<p>More than 50,000 <a href=\"https:\/\/defensescoop.com\/2026\/04\/07\/us-launches-more-attack-drones-iran-epic-fury-adm-cooper-centcom\/\" rel=\"nofollow noopener\" target=\"_blank\">American troops deployed<\/a> across the Middle East, Europe and stateside have participated in Operation Epic Fury to date.<\/p>\n<p>\u201cAlong the way, we consumed more than 6 million meals, and by my estimate, more than 950,000 gallons of coffee, 2 million energy drinks and a lot of nicotine \u2014 but I\u2019m not saying that we have a problem,\u201d Caine said on Wednesday. \u201cI\u2019ve laid out the statistics, but it does not truly capture the nature of combat. This is gritty and unforgiving business. It\u2019s chaotic, it\u2019s hot, it\u2019s dark, it\u2019s unpredictable, and there\u2019s always unknowns, and our people proudly walk into those unknowns and continue forward.\u201d<\/p>\n<p>The experts who DefenseScoop spoke to suggested that the press conference was notably silent on certain elements of strategic significance.<\/p>\n<p>\u201cHegseth and Caine described a devastatingly successful military campaign \u2014 and by traditional measures of firepower and target destruction, it may well have been. But the Strait of Hormuz required a ceasefire that left Iran as a gatekeeper of the world\u2019s most critical oil chokepoint. The regime survived. The nuclear knowledge base survived,\u201d Grieco said. \u201cA briefing that leads with 90% of the navy sunk while not addressing any of that is selling a victory, not offering a strategic assessment.\u201d<\/p>\n<p>The U.S. military conducts systematic evaluations of the physical and functional results of military force against targets, which measure how tactical objectives were met and assist decision-making on re-attacking assets.<\/p>\n<p>\u201cBattle damage assessment (BDA) is one of the hardest intelligence problems there is, and history suggests initial claims are almost always optimistic,\u201d Grieco noted. \u201cKnowing you hit a target is different from knowing what was actually in it, whether it was operational, and whether backup systems or redundant facilities existed elsewhere.\u201d\u00a0<\/p>\n<p>Both she and the former senior defense official pointed to Caine\u2019s account that 2,000 C2 nodes had been destroyed as ambiguous and subject to change.<\/p>\n<p>\u201c[That] is the kind of specific number that sounds precise but may reflect targets struck rather than capabilities eliminated. I\u2019d want to know what the classified confidence levels on these assessments actually are before taking any of these figures at face value,\u201d Grieco said.<\/p>\n<p>A former senior defense official said: \u201cWhat do you define a C2 node as? I don\u2019t know, a radio-relay tower, or it could be a military headquarters. It could be a lot of different things. But the question is, how critical was that thing?\u201d\u00a0<\/p>\n<p>In their decades-long military and defense career, the official noted that they became \u201cvery, very familiar\u201d with the U.S. military\u2019s approaches for conducting BDAs and other combat-related after-action reviews. Immediate assessments pull from weapons systems that were used, and if necessary more methodical reassessments occur as new intelligence and sources emerge.<\/p>\n<p>\u201cSo, all these things have been put in place to say there is a very good, methodical process to try to assess this,\u201d the former senior defense official told DefenseScoop. \u201cAnd we learned from it time and time again.\u201d<\/p>\n<p>\t\t\t\t\t<img decoding=\"async\" class=\"author-card__image\" src=\"https:\/\/www.europesays.com\/iran\/wp-content\/uploads\/2026\/04\/Image-from-iOS-2-e1662581202907.jpg\" alt=\"Brandi Vincent\"\/><\/p>\n<p>\n\t\t\tWritten by Brandi Vincent<br \/>\n\t\t\tBrandi Vincent is a Senior Reporter at DefenseScoop, where she reports on disruptive technologies and associated policies impacting Pentagon and military personnel.
