‘Conflict not over’: Oil at risk as Strait of Hormuz shuts amid unresolved Iran war

Key Concepts

• Strait of Hormuz: A critical maritime chokepoint for global oil transit, currently experiencing heightened tensions and closure.
• Asymmetric Warfare: The use of low-cost, high-volume weaponry (drones) to overwhelm expensive, sophisticated defense systems.
• Revolutionary Guards (IRGC): The faction within Iran currently exerting control over maritime policy and military actions in the Strait.
• Strategic Defense Procurement: The shift from purchasing small numbers of high-cost assets to addressing the need for sustainable, high-volume defense capabilities.
• Henderson Shipbuilding Precinct: The Western Australian facility designated for the future domestic construction of Japanese-designed frigates.

1. The Crisis in the Strait of Hormuz

Peter Jennings highlights that the closure of the Strait of Hormuz is a direct result of internal power struggles within Tehran, where the Revolutionary Guards have gained the upper hand over more moderate diplomatic voices.

• Military Escalation: The firing on tankers by the Revolutionary Guard’s naval elements signals a high risk of conflict.
• US Involvement: As the primary naval power in the region, the US is currently engaged in mine-sweeping operations. Jennings argues that the potential for accidental or intentional conflict remains high, effectively halting the flow of crude oil through the region.

2. The Impact of Low-Cost Drones on Modern Warfare

The discussion addresses the shift in military strategy caused by the proliferation of cheap, mass-produced drones.

• The "Cost-Exchange" Problem: Drones costing between $35,000 and $50,000 are being used to overwhelm Western defense systems that cost significantly more.
• Strategic Implications: Jennings notes that while Western air defenses are technically capable, they are not designed for the sheer volume of incoming threats. He argues that Australia’s current defense strategy—focused on buying small numbers of expensive equipment—is unsustainable and requires a fundamental rethink to address the reality of modern, high-volume warfare.

3. Australia-US Alliance and Diplomatic Protocol

A point of contention is the criticism from Donald Trump regarding Australia’s lack of presence in the Strait of Hormuz.

• Leadership Critique: Jennings argues that the Albanese government’s reliance on the "lack of a formal request" as an excuse for inaction is a failure of leadership.
• Communication Gap: Jennings asserts that as a close ally, the Prime Minister should have proactively engaged with the US President rather than hiding behind bureaucratic protocol. He characterizes the current approach as a reluctance to engage with Trump, which he views as a strategic error.

4. Australia-Japan Frigate Deal

Australia has signed a $10 billion contract for three Japanese-built frigates, with the first delivery expected in 2029 and the subsequent two by 2034.

• Design Choice: Jennings praises the selection of the Japanese design as the most modern and capable warship available.
• The "Henderson Challenge": The plan involves transferring intellectual property to the Henderson shipyard in Western Australia to build the remaining seven or eight ships.
• Risk Assessment: Jennings expresses skepticism regarding the domestic construction phase. He notes that Japan has not exported warships since WWII, and the Henderson facility lacks experience in constructing large steel-hulled warships.
• Prediction: Jennings predicts that the Australian government will eventually abandon the plan to build the remaining frigates in Australia, concluding that it is more efficient to have them built in Japan while utilizing the Henderson facility for maintenance.

Synthesis and Conclusion

The situation in the Strait of Hormuz serves as a microcosm for broader geopolitical instability, where internal Iranian power dynamics and the rise of asymmetric drone warfare are challenging traditional military doctrines. Australia faces a dual challenge: it must modernize its defense procurement to account for the "drone threat" while navigating the complexities of its alliance with the US and its new naval partnership with Japan. Jennings concludes that while the Japanese frigate design is sound, the ambition to transition to domestic production at Henderson is high-risk and likely to be reconsidered in favor of continued Japanese manufacturing.
