As naval tensions rise once more within the Strait of Hormuz – this time between Iran and the US – we break down what occurred within the Eighties and study the parallels and variations between the conditions then and now:

How the Eighties Tanker Battle performed out – a timeline
The warfare between Iran and Iraq started in 1980 when then-Iraqi President Saddam Hussein launched a full-scale invasion of Iran following Iran’s 1979 Islamic revolution.
In 1984, this warfare reached the Gulf when Iraq attacked Iranian oil tankers, in search of to cripple its oil-revenue-dependent financial system. Iran retaliated by firing at oil tankers belonging to Iraq and its allies within the Gulf.
In keeping with a report by the College of Texas’s Robert Strauss Heart for Worldwide Safety and Legislation, Iran additionally threatened to shut the Strait of Hormuz then, however didn’t accomplish that since its personal financial system, already crippled by the warfare, was depending on exporting oil to the remainder of the world by it.
In November 1986, when Iran struck Kuwait’s ships, Kuwait requested for international assist. The previous Soviet Union was the primary to reply and helped escort the nation’s ships within the Gulf.
The US, led by then-president Ronald Reagan, launched Operation Earnest Will in July 1987, additionally in search of to guard tankers within the Gulf and render extra help than Moscow. The operation concerned reflagging Kuwaiti tankers with the US flag so they may legally sail underneath US safety.
In keeping with an article by the Veterans Breakfast Membership, a US-based web site which shares experiences of former US navy veterans, throughout Washington’s very first escort mission in July 1987, a reflagged tanker hit an Iranian mine within the Gulf.
“The convoy continued, however the incident made clear that the USA had entered a shadow warfare with Iran at sea,” the article stated.
“Over the following fourteen months, dozens of US warships rotated by the area escorting tankers and defending delivery lanes. US forces additionally carried out particular operations to hunt Iranian mine-layers at evening and carried out strikes towards Iranian navy positions and ships. The mission wasn’t a small one, consuming 30 US Navy ships at one time,” the article added.
Then in April 1988, the US frigate USS Samuel B Roberts was broken by an Iranian mine within the Strait of Hormuz. Historian Samuel Cox, writing for the US Naval Historical past and Heritage Command (NHHC), famous in 2018 that by the tip of 1987 that vessel was so badly broken, that “the one factor really holding the ship collectively was the primary deck”.
So, the US launched Operation Praying Mantis, in search of to destroy Iranian vessels.
The tanker warfare ultimately resulted in August 1988, following a United Nations-brokered ceasefire settlement between Iran and Iraq.
Cox famous that by the tip of 1987, “Iraq had carried out 283 assaults on delivery, whereas Iran attacked 168 instances. Mixed, the assaults had killed 116 service provider sailors, with 37 lacking and 167 wounded, from all kinds of nationalities.”
“Initially, there was nice concern that the assaults would lower off the important move of oil from the Arabian Gulf, however all they actually did was drive up insurance coverage charges. The world’s want for oil was so nice, that over 100 lifeless service provider seamen was apparently a suitable worth,” he wrote.

What is going on within the Strait of Hormuz now?
The present hostilities between the US and Iran within the Strait of Hormuz started when Tehran, whose territorial waters prolong into the strait, closed passage to all vessels after the US and Israel started bombing the nation. On March 4, the Islamic Revolutionary Guard Corps (IRGC) declared that it was in full management of the strait, and ships would want to get clearance from them to move by it.
Transport by the strait collapsed by 95 p.c, sending the value of oil – 20 p.c of worldwide provides of that are shipped this fashion – hovering above $100 a barrel.
Iran, by its imposition of management over who passes by Hormuz, has for nearly eight weeks now, decided which vessels can exit the strait from the Gulf into the Gulf of Oman.
At first, Iran indicated that it might enable “pleasant” ships to move in the event that they paid a toll. On March 26, Iran’s International Minister Abbas Araghchi instructed Iran’s state TV: “The Strait of Hormuz, from our perspective, just isn’t utterly closed. It’s closed solely to enemies. There isn’t a purpose to permit the ships of our enemies and their allies to move.”
Vessels from Malaysia, China, Egypt, South Korea, India and Pakistan handed by the strait by most of March and early April.
Iran’s Islamic Revolutionary Guard Corps (IRGC) offered these vessels with an alternate route by the Strait of Hormuz to keep away from potential sea mines. US officers, together with Donald Trump, have stated mines have been positioned there by Iran, though it has not formally confirmed or denied this.

However on April 13, alarmed that Iran was persevering with to ship its personal oil out of the strait, the US imposed a naval blockade of all Iranian ports. Since then, US Central Command has stated US forces have directed 33 Iran-linked vessels to show round or return to an Iranian port.
On Monday, the US navy fired on after which captured the Iranian-flagged container ship Touska near the Strait of Hormuz within the northern Arabian Sea, and, a day later, detained one other oil tanker sanctioned for transporting Iranian crude oil because it sailed within the Bay of Bengal, which hyperlinks India and Southeast Asia.
In a submit on social media after detaining the Touska, the Pentagon wrote: “As we’ve made clear, we are going to pursue world maritime enforcement efforts to disrupt illicit networks and interdict sanctioned vessels offering materials assist to Iran – anyplace they function. Worldwide waters usually are not a refuge for sanctioned vessels.”
For the reason that US naval blockade of Iranian ports started, Tehran, which was earlier permitting vessels from “pleasant” nations to move by the Strait of Hormuz, has additional tightened its grip on the strait.
Justifying the choice to not enable any international ships to move till the US ends its naval blockade on April 19, Iran’s First Vice President Mohammad Reza Aref stated the “safety of the Strait of Hormuz just isn’t free”.
“One can not prohibit Iran’s oil exports whereas anticipating free safety for others,” he wrote in a submit on X.
Final Saturday, Iran reportedly fired at two Indian-flagged service provider vessels within the strait. The IRGC stated the 2 ships have been attacked as a result of they have been “working with out authorisation”, in response to state media studies.
Then, on April 22, Iran captured two container ships in search of to exit the Gulf through the Strait of Hormuz after firing on them and one other vessel.
What are the parallels between the 2 wars?
Similar to throughout the Tanker Battle of the Eighties, delivery has been severely disrupted by the US-Israel warfare on Iran, upending world oil and gasoline costs.
In accordance to an April 17 article by the World Financial Discussion board, from the mid-Eighties when the Tanker Battle befell, to the beginning of the brand new millennium, a barrel of crude oil averaged $20.
On Friday, whereas a ceasefire between the US and Iran was in impact, a naval battle was nonetheless taking part in out within the Strait of Hormuz, and Brent crude, the worldwide benchmark, topped $106 per barrel. Throughout open warfare between the US, Israel and Iran in March and early April, oil rose as excessive as $119 per barrel.
Mines within the sea are one other downside widespread to each time durations.
Whereas vessels have been broken by mines throughout the Eighties Tanker Battle, there has up to now been no report of vessels being broken by mines within the present warfare. Nonetheless, the chance is similar.
US President Donald Trump has stated the US will ramp up efforts to take away mines from the Strait of Hormuz. This has not begun but, nonetheless.
In keeping with CNN, there are just a few US minesweeping ships within the Gulf. The US Navy additionally instructed the broadcaster that 4 devoted minesweepers stationed within the Gulf area have been decommissioned final yr.
John Phillips, a British security, safety and danger adviser and former navy teacher, instructed Al Jazeera: “There are some clear parallels between the present scenario in Hormuz and the Tanker Battle of the Eighties. In each circumstances, the fundamental thought is similar: strain at sea can have results far past the water itself.
“A comparatively small quantity of naval disruption, whether or not which means mining, harassment of delivery, missile threats, or assaults on tankers, can create actual strategic and financial penalties, particularly in a chokepoint just like the Strait of Hormuz. So in that sense, the unique Tanker Battle is a helpful reminder of how susceptible world commerce could be when the maritime area turns into a part of a wider political or navy confrontation.”
What are the variations between the 2 wars?
Through the Tanker Battle, the US escorted ships to guard them from Iranian assaults and in addition deployed vessels to take away mines. NATO international locations like the UK, Belgium, the Netherlands, France and Italy additionally joined.
However within the present standoff within the Strait of Hormuz, US allies just like the UK and different NATO nations have refused to affix Washington in reopening the Strait of Hormuz, or start minesweeping operations, fearing they are going to be dragged into the warfare.
In a submit on Reality Social in early April, the US president took intention at allies, “like the UK”, which, he stated, have “refused to become involved within the decapitation of Iran”, telling them to both purchase US gasoline or become involved within the quickly escalating warfare.
“You’ll have to start out studying the best way to battle for your self, the united statesA. gained’t be there that can assist you anymore, identical to you weren’t there for us. Iran has been, basically, decimated. The laborious half is completed. Go get your individual oil!” Trump wrote.
The framework of the US-Israel warfare on Iran is completely different from that of the warfare between Iraq and Iran within the Eighties, specialists say.
“Within the Eighties, the Tanker Battle was a part of the broader Iran-Iraq Battle, so the delivery assaults have been tied to a a lot bigger land battle between two regional armies. Right now, the scenario is extra about Iran’s standoff with the USA and its allies, and the maritime exercise is much less about asymmetrical warfare at sea and extra about deterrence, signalling and the specter of escalation,” stated Phillips.
“The navy lesson, actually, is that Hormuz continues to be a type of locations the place restricted actions can have outsized results, however the fashionable setting is extra fast-moving, extra technologically superior and probably extra unstable than the unique Tanker Battle,” he added.
Analysts have additionally identified that, not like within the Eighties, Iran is at present stronger on the subject of withstanding assaults and naval blockades by the US.
Within the Tanker Battle, Iraq was militarily supported by Western allies, whereas Iran was underneath a US arms embargo imposed in 1979 after the Iranian revolution. Whereas this gave Iraq a navy benefit, Iran’s IRGC used uneven warfare ways by hanging Iraq’s allies’ ships and oil tankers.
Specialists additionally say that for the reason that 12-day warfare between Iran and Israel final yr, Tehran has shifted its navy doctrine from one that’s primarily about defensive containment to an explicitly offensive uneven posture.
“Iran right now seems extra structurally aggressive in doctrine the place it’s formally embracing earlier and extra in depth use of regional missiles, drones, cyberattacks and vitality coercion [when energy resources and infrastructure are targeted or cut off], however is operationally constrained by battle injury, sanctions and inside instability,” Phillips, the chance adviser and a former navy chief teacher, instructed Al Jazeera in an interview on March 2.
A former US ambassador to Bahrain, Adam Ereli, additionally instructed Al Jazeera that Iran and the IRGC have “revolutionary fervour”, which implies they’ll “survive”.
“They will tolerate ache for lots longer than I believe most American decision-makers and planners calculate,” he stated.
