In 1987, Iran Mined Hormuz and It Took Years to Reopen. We're Doing This Again.
The USS Samuel B. Roberts hit an Iranian M-08 mine on April 14, 1988. The keel cracked. Ten sailors injured. The mine cost $1,500. The ship cost $200 million to repair. Iran had thousands more mines in the Gulf. Clearance took years after the ceasefire. Every single dimension of the 2026 crisis is worse.
April 14, 1988. The USS Samuel B. Roberts (FFG-58) struck an Iranian M-08 contact mine in the central Persian Gulf. The keel cracked. A 21-foot hole opened in the hull. Ten sailors were injured. The ship nearly sank. Only the crew's damage control saved it. The mine cost approximately $1,500. The repair cost $96 million.
Three days later, the US launched Operation Praying Mantis, the largest American naval engagement since World War II. The US Navy sank or damaged half of Iran's operational fleet in a single afternoon. Iran accepted UN Resolution 598 four months later.
The Tanker War (1984-1988) is the closest historical parallel to the current Hormuz crisis. Every comparison makes 2026 look worse.
Iran's mine stockpile in 1988: estimated 1,000-2,000. In 2026: 5,000-6,000, with rocket-delivered variants that didn't exist in the 1980s. US dedicated minesweepers in 1988: a full MCM squadron. In 2026: zero, all decommissioned. Insurance normalization after the 1988 ceasefire: 12-18 months. Projected for 2026: 14+ months minimum. Mines found in the Gulf after the 1988 ceasefire: for years. The seabed still isn't fully cleared.
Reagan's solution was "reflagging": Kuwaiti tankers were re-registered under the US flag, entitling them to US Navy escort. The escorts worked, mostly. But reflagging doesn't work against mines. An escort can protect against Iranian surface vessels and aircraft. It can't protect against a mine sitting on the seabed that was laid by rocket from 80 km inland.
The Tanker War ended because both Iran and Iraq were exhausted after eight years of war. The 2026 crisis is in Day 26. Iran is not exhausted. Its mine stockpile is largely untouched. Its rocket-delivery capability is immune to naval interdiction. And the US Navy, which had the world's most capable mine countermeasure force in 1988, scrapped it in 2025.
History doesn't repeat. But when the same waterway, the same adversary, the same weapon system, and the same underestimation of mine warfare converge 38 years apart, the word "parallel" undersells the comparison.
FAQ
Did Operation Praying Mantis deter Iran from mining?
Temporarily. Iran reduced mine-laying after Praying Mantis but did not stop entirely. Mines were found in the Gulf months after the ceasefire. The lesson Iran drew was not "don't mine" but "mine more carefully and with deniability." The 2026 rocket-delivery system is the direct descendant of that lesson.
Could a modern Operation Praying Mantis work?
The US Navy could destroy Iran's remaining surface fleet in hours. It largely already has (20+ ships sunk since February 28). But destroying the fleet doesn't stop the mines, because mines arrive by rocket from shore launchers, not by ship. Praying Mantis solved a 1988 problem. The 2026 problem is different in kind, not just degree.
How long did it take to fully clear Tanker War mines?
Mines were encountered in the Gulf for years after the 1988 ceasefire. Full clearance was never formally declared because the confidence level could never reach 100% in a body of water that large. Commercial shipping resumed under escort within weeks but unescorted transit didn't normalize for 12-18 months. Insurance markets took longer. The 2026 stockpile is 3-6x larger with more sophisticated mine types.
