Two-thirds of outbound tankers are ‘going dark’ to squeeze through the Strait of Hormuz: analysts
New York Post
Overall Assessment
The article reports on a significant shift in tanker behavior using credible data sources and avoids overt editorializing. It emphasizes operational trends over political narratives but gives some unverified weight to Iranian claims. The framing is largely technical, focusing on shipping patterns amid regional conflict.
"Two-thirds of outbound tankers are ‘going dark’ to squeeze through the Strait of Hormuz: analysts"
Headline / Body Mismatch
Headline & Lead 85/100
The headline accurately reflects the article's focus on increased use of shadow tactics by tankers in the Strait of Hormuz, citing analysts. The lead paragraph clearly introduces the core data point—65% of outbound tankers going dark in May—without sensationalism. Language remains descriptive and grounded in attributed data.
✕ Headline / Body Mismatch: The headline uses a precise statistic ('two-thirds') and attributes it to analysts, which adds specificity and indicates sourcing. It focuses on a measurable phenomenon ('going dark') without exaggeration.
"Two-thirds of outbound tankers are ‘going dark’ to squeeze through the Strait of Hormuz: analysts"
Language & Tone 80/100
Language is mostly neutral and technical, though occasional word choices ('sneaking,' 'shadow fleet') introduce subtle negative framing. Overall tone prioritizes data over emotion, avoiding overt sensationalism or moral judgment.
✕ Loaded Labels: The term 'shadow fleet' is standard industry terminology but carries slightly ominous connotations; however, it is used consistently and neutrally throughout.
"Iran’s shadow fleet to transport sanctioned oil"
✕ Loaded Verbs: Use of 'sneaking through' introduces a moralized verb implying deception, which could bias perception of neutral commercial behavior under duress.
"dozens more are believed to be sneaking through"
✕ Passive-Voice Agency Obfuscation: Passive voice is used in places where agency could be clearer, such as 'ships are essentially switching off,' which avoids specifying who makes the decision.
"The ships are essentially switching off their Automatic Identification System (AIS)"
Balance 80/100
Relies on credible, specialized data firms for core claims and includes Iranian assertions, though with less critical scrutiny. Could improve by including more diverse stakeholder perspectives (e.g., Omani or UAE officials, international maritime bodies).
✓ Comprehensive Sourcing: The article cites two reputable maritime data firms—Kpler and Vortexa—providing specific figures and analysis. These are neutral, technical sources with no apparent political agenda.
"According to maritime data company Kpler."
✕ Vague Attribution: The article includes Iran’s claim about supervising dozens of ships but does not attribute verification to independent sources, creating a slight imbalance in assessing Tehran’s assertions.
"Iran claiming dozens of ships were transiting through strait under their supervision in recent days."
Story Angle 85/100
The story is framed around a shift in maritime operational norms due to regional insecurity, supported by data trends. It avoids simplistic conflict framing and instead highlights evolving behavior across multiple national shipping interests.
✕ Framing by Emphasis: The article frames the story around a measurable trend—increased use of AIS-off tactics—rather than reducing it to a moral or political battle. This reflects a systemic, data-driven angle.
"That shift suggests AIS-off behaviour is becoming an accepted operating protocol, not an exceptional measure,” Vortexa warned."
✕ Narrative Framing: It avoids reducing the situation to a simple conflict narrative between Iran and the US, instead focusing on adaptive behaviors by multiple national fleets (China, India, Japan, etc.).
"Vessels linked with Iran, China, India, Pakistan and Japan have made use of this to get their cargo ships out"
Completeness 75/100
The article includes relevant recent trends and operational details about tanker movements but lacks deeper historical or legal context about maritime sanctions evasion or the strategic importance of the Strait of Hormuz over time.
✓ Contextualisation: The article provides context on the rise in AIS-off behavior from 37% to 65%, showing a trend rather than presenting a single data point. It also explains the operational risks (mines, drones) and geopolitical stakes (US blockade, Iranian tolls).
"While only 37% of the outbound tankers had been using shadow fleet tactics to “go dark” and avoid detection during the first month of the war, the number had shot up to 65% in May, according to shipping analytics firm Vortexa."
✕ Missing Historical Context: The article omits broader historical context about Iran’s long-standing use of shadow fleets and the legal framework around maritime transit in contested straits, which would help readers understand the precedent and norms.
Maritime transit portrayed as highly endangered due to regional conflict
The article repeatedly emphasizes danger in the Strait of Hormuz—mines, drones, fast-attack ships, and blockades—framing the area as inherently unsafe. This heightens perception of threat even while describing adaptive commercial responses.
"Ships can either take Iran’s offer of paying tolls of up to $2 million to be instructed on safe passage through the strait, which is believed to be littered with mines and within reach of Tehran’s drones and fast-attack ships."
Iran framed as a hostile facilitator of risky maritime behavior
The article attributes the 'shadow fleet' tactic to Iran and notes its role in establishing the template for evading detection, linking it directly to sanctioned oil transport and offering paid safe passage through a militarized strait. While factual, this emphasizes Iran’s central role in enabling covert operations without equivalent scrutiny of other actors’ strategic choices.
"The ships are essentially switching off their Automatic Identification System (AIS) before and after transiting the strait, a technique used by Iran’s shadow fleet to transport sanctioned oil through the Strait of Hormuz."
Global oil supply framed as being in escalating crisis
The article highlights a sharp increase in oil flow disruption—from 500,000 to 710,000 barrels per day lost—framing the situation as deteriorating rapidly. This contributes to a narrative of economic instability driven by geopolitical conflict.
"With larger drops seen in recent weeks. The average loss of oil within the first month of the conflict peaked at around 500,000 barrels per day, but starting in May, the depletion rate ramped up to 710,000 bpd, according to Reuters."
US naval presence framed as a protective force for commercial shipping
The article notes that ships taking routes near Oman are likely supported by the US Navy, and cites Central Command’s assistance to around 70 ships—framing the US as a stabilizing, cooperative actor in contrast to Iranian coercion.
"Others have instead opted on taking routes closer to Oman’s coastline, with the US Navy likely supporting those ships as Central Command recently touted helping around 70 ships cross in the last three weeks."
Maritime monitoring systems portrayed as increasingly ineffective
By highlighting that two-thirds of tankers are now 'going dark' and that AIS-off behavior is becoming standard, the article implicitly frames existing maritime tracking and border control mechanisms as failing under pressure.
"That shift suggests AIS-off behaviour is becoming an accepted operating protocol, not an exceptional measure,” Vortexa warned."
The article reports on a significant shift in tanker behavior using credible data sources and avoids overt editorializing. It emphasizes operational trends over political narratives but gives some unverified weight to Iranian claims. The framing is largely technical, focusing on shipping patterns amid regional conflict.
Maritime analytics firms report a significant increase in oil tankers disabling their Automatic Identification Systems while transiting the Strait of Hormuz in May, rising from 37% to 65% since the start of the conflict. The practice, used to evade detection, reflects growing reliance on shadow fleet tactics amid regional tensions and security threats.
