From Hormuz to the South China Sea: Defending Freedom of Navigation in Contested Waters

RealClearDefense | David F. Lasseter

Iranian forces have conducted a seven-month campaign of commercial tanker seizures, drone strikes, and vessel harassment in the Strait of Hormuz, threatening global transit passage. In response, the United States Navy established weeks of continuous merchant vessel escorts while enforcing naval blockades to secure vital energy trade routes.

These Middle Eastern disruptions coincide with Chinese coercion across the Indo-Pacific, where Beijing uses maritime militia, water-cannon attacks, and artificial island militarization against regional states. China's actions ignore the 2016 Permanent Court of Arbitration ruling. To counter these dual threats, David F. Lasseter proposes combining diplomatic actions with Freedom of Navigation Operations. This strategy relies on expanding existing frameworks like AUKUS and the Quad into multilateral patrol coalitions. A primary initiative calls for a standing international escort mission in Hormuz supported by NATO allies. Establishing combined patrols prevents illegal maritime assertions from solidifying into customary practice.

Comment

Multilateral maritime escort missions face distinct operational frictions when attempting to integrate non-treaty partners into established command structures. Expanding task forces built around AUKUS or Quad frameworks requires standardized rules of engagement and real-time tactical data sharing through platforms like the Link 16 tactical data network. While NATO members possess institutionalised interoperability protocols, non-aligned navies often operate with divergent operational security standards and legal restrictions regarding defensive fires. Consequently, integrated escorts through contested chokepoints frequently default to bilateral coordination arrangements rather than unified coalition command structures.

This command friction was evident during Operation Sentinel under the International Maritime Security Construct in the Persian Gulf. Participating navies, including the Royal Navy and US Fifth Fleet, established parallel patrol sectors rather than fully integrated tactical formations to accommodate differing national caveats. In high-threat environments near the Strait of Hormuz, these procedural firewalls slow the joint target-allocation cycle across mixed Arleigh Burke and Type 45 destroyer squadrons.

Strategic Question for Discussion

If coalition escorts in the Strait of Hormuz rely on parallel patrol sectors like those used during Operation Sentinel, does national-caveat friction inherently limit multi-nation response speeds against saturation missile attacks?

The available evidence points toward structural delays whenever multi-nation task forces operate under unharmonized rules of engagement. While parallel sectors prevent national legal friction during routine transits, high-density threat environments expose response lags caused by disjointed fire-control delegation. My assessment is that tactical coordination across unintegrated task groups will remain constrained by national caveats rather than sensor capability.
