The Mine Lesson America Forgot: 1987 Tanker War Playbook Repeating

In April 1988, the USS Samuel B. Roberts—a guided-missile frigate—transited the Persian Gulf heading for resupply after completing 24 successful escort missions. The ship struck an Iranian moored contact mine laid overnight. The explosion estimated at 500 pounds snapped the frigate's keel and punched a 15-foot hole in its hull. Only the main deck held the ship together. Its crew used heavy steel cables to bind fractured superstructure together and prevented capsizing. Ten sailors were wounded; the crew's discipline saved the ship from breaking in half.

That incident, part of the 1987-1988 Tanker War, exposed a critical US Navy vulnerability: mine countermeasures are slow, meticulous, and require specialized assets the Navy has chronically underinvested in. Because missile battles are flashy and produce quick wins, mine-clearing capability has been the first thing eliminated in budget cycles. The Navy relied on allies to fill that gap.

Today, the same pattern is repeating—but the US is less prepared.

The Strait of Hormuz is believed to be mined by Iranian forces. US intelligence confirms that Tehran has laid some ordnance in the waterway. Unlike 1987, when the Navy had a standing minesweeping fleet with dedicated assets on station, the current force posture is dangerously lean. Four dedicated minesweepers based in the region were decommissioned last year. Two of three Littoral Combat Ships (LCS) that were supposed to take over minesweeping duties were in Malaysia as of this week for logistics stops. The Navy has no immediate surge capacity for mine countermeasures.

President Trump called on allies to deploy minesweepers. None have offered hardware yet. A joint statement from the UK, France, Germany, Italy, the Netherlands, Japan, and Canada pledged "contribution to safe passage" but specified nothing—no vessels, no assets, no timeline. Compare this to 1987, when Belgium, France, Italy, the Netherlands, and the UK actually showed up with ships and personnel to participate in escorting and active minesweeping operations.

The psychological and operational effect of mines is profound. Mines constrain how warships operate. They limit the range and positioning of escort formations. They create operational uncertainty that slows convoy throughput. An escort force without dedicated mine countermeasures is an escort force operating with one hand tied.

The historical parallel is clear: escorting tankers is not a novel mission. It happened in the 1980s. The Navy learned hard lessons then. The current situation suggests those lessons were filed away, not internalized. The Bridgeton—a massive tanker that struck a mine in July 1987—was used by US escorts as a makeshift minesweeper, a tacitly humiliating acknowledgment that the Navy was short on proper assets.

History is not repeating, but it is rhyming. And the cost of ignoring that rhyme is measured in damaged hulls and near-losses.
