IRGC orders a ship to turn back, shifting Hormuz from strikes to pre-transit denial

gCaptain reported on 5 October that the UK Maritime Trade Operations centre issued three new “time-late” warnings on Sunday: an LPG tanker struck inbound at 1716 UTC on 4 October, a crude tanker struck at 1907 UTC the same day, and a third crude tanker hit above the waterline during a 3 October transit. The Joint Maritime Information Center’s 4 October advisory separately documented four confirmed tanker attacks on 2 and 3 October, logged as incidents 147-26 through 150-26, with attacks continuing along the Omani side of the Strait. In one case a drone entered a tanker’s funnel before dropping into the engine room, starting a small fire; another vessel lost power, drifted, then made Fujairah under tug. No crew casualties were reported in those four. In the same report, the IRGC threatened an inbound vessel unless it turned around.

The named damage is concrete. TradeWinds reported on 4 October that the Lipsi, a 115,100-dwt LR2 delivered from a Chinese yard on 24 August 2026 — six weeks old, Chinese lease-financed, operated from Greece by Dynacom Tankers — took projectile damage in its engine room. Seatrade Maritime reported the Kuwait-flagged VLCC Kazimah III ablaze after a strike at 1750 UTC on 1 October, identified not by UKMTO but by the security firm Vanguard Tech using Pole Star Global’s PurpleTrac. Reuters, via OilPrice, reported that the ADNOC-managed Al Ruwais and Mersin Prosperity were among three Liberia-flagged tankers hit on 29 and 30 September while running with transponders off, sourced to the intelligence firm Marisks. Attribution for the attacks themselves is thinner than the damage reports: UKMTO says only “unknown projectile.”

The only party claiming the strikes is Iran. The Hormuz tracker straits.live records an IRGC claim, carried by Fars and relayed through Hellenic Shipping News, that its navy targeted at least seven tankers over five days — and notes that in each case the attacker is identified solely by that Iranian claim. Iranian state media, carried by several outlets, also asserted that the Emirati-managed tankers appeared on an Iranian “non-compliance” list; that too is a claim, not a finding. gCaptain’s own caveat belongs in any tally: “the use of delayed reporting makes the precise number of individual incidents difficult to establish.” TradeWinds put last week’s hit count at seven, tied for the fourth-highest weekly total since the war began. AP, via Arab News, reported UKMTO describing Friday’s incident as the fifth “in recent days.”

Assessment: Watch the direction of the pressure, not the arithmetic. Striking a tanker after it has entered the Strait is punishment; ordering one to reverse before it enters is control, and it is cheaper — a radio call costs Tehran nothing and risks no ordnance. If turn-back orders recur, the insurance market will price the waterway off threats rather than wreckage, which is precisely what an adversary short on munitions would want. Distrust the counting in both directions. Time-late reporting inflates nothing but obscures everything, and the sole claimant of authorship is also the party with the most to gain from appearing more capable than it is. IRNA’s assertion that no US vessels are in the Gulf at all is a useful calibration of how much Iranian claims are worth.
