Iran unveils 27 Rajab cruise-missile attack craft as US talks drift

TEHRAN — Iran unveiled a new high-speed naval attack craft armed with long-range cruise missiles at Tehran’s Enqelab Square on Saturday, the same week Iranian officials told Middle East Eye that several major issues remain unresolved in talks with Washington over frozen assets, sanctions relief and a proposed reconstruction fund.

The display of the vessel, named “27 Rajab,” marks the latest in a series of Iranian military reveals that have run in parallel with quiet diplomacy, underscoring Tehran’s strategy of pairing pressure from the negotiating table with visible upgrades to its Persian Gulf posture. For shipping operators, insurers and Gulf capitals tracking the Strait of Hormuz, the unveiling is a reminder that the maritime balance has not paused for the talks.

The vessel

According to the semi-official Fars news agency, the 27 Rajab is capable of speeds up to 100 knots, roughly 185 kilometers per hour, and carries long-range cruise missiles. Fars described the craft as “a new symbol of Iran’s maritime military capabilities.”

The unveiling took place at Enqelab Square in central Tehran, a state-symbolic venue typically reserved for political and military events of national significance rather than for routine procurement announcements. Iranian state media did not publish detailed specifications on the cruise missile loadout, range or guidance package at the time of the display, and Iran did not announce a commissioning date or operational service entry.

Iranian officials did not say whether the 27 Rajab will be assigned to the regular Iranian Navy, which patrols open ocean and the Sea of Oman, or to the Islamic Revolutionary Guard Corps Navy, which operates the small-boat and fast-attack forces concentrated inside the Persian Gulf and around the Strait of Hormuz. That distinction matters operationally: IRGC Navy units have driven most of the recent close-quarters incidents involving commercial shipping and US naval assets.

Talks unresolved

The vessel reveal landed against a backdrop of slowing diplomacy. Iranian officials told Middle East Eye that several major sticking points remain before any formal announcement of a deal framework.

On frozen assets, Tehran is pressing for “immediate” return upon any deal announcement, while the United States prefers what Iranian officials characterized as “a gradual, performance-based process,” according to the report. Iran is also seeking commitments around a proposed $300 billion “construction fund” tied to reconstruction and reinvestment, and is pushing for sanctions relief on the oil and petrochemicals sectors that drive its export economy.

Negotiations are continuing through Pakistani mediators and other regional actors, the report said. Pakistan has emerged in recent rounds as a back-channel host alongside other regional capitals, a role Islamabad has not publicly confirmed in detail.

The state of the draft itself remains in flux. Iran’s lead negotiator told reporters this week that the final draft has not been approved and accused Washington of previous deal violations, comments that landed alongside reporting that the two sides are still some distance from a signing posture.

US posture

Across the region, US officials have continued to signal that the military option remains live. Defense Secretary Pete Hegseth told the Shangri-La Dialogue in Singapore on Saturday that the United States is more than capable of restarting the war if Iran reneges and that American stockpiles are “more than suited for that.” The Hegseth remarks, delivered against the backdrop of a $1.5 trillion defense topline, are the clearest recent statement of US deterrence posture toward Tehran.

The Pentagon has not commented publicly on the 27 Rajab unveiling.

Hormuz and the IRGC track

The Tehran display fits into a broader pattern of Iranian maritime signaling that has run in parallel with the diplomatic track. The Iranian parliament this week advanced a Strait Management bill backed by IRGC-aligned lawmakers that would expand Tehran’s claimed regulatory authority over commercial traffic transiting the Strait of Hormuz, a chokepoint that handles roughly a fifth of global oil flows.

That legislative push followed an IRGC live-fire incident in the Strait earlier in the week, during which Vice President JD Vance described the United States and Iran as “very close” to a deal even as the on-water tempo escalated. Taken together, the parliamentary action, the live-fire incident and the 27 Rajab display indicate that Iranian military and political institutions are continuing to build leverage on the maritime track regardless of the diplomatic timeline.

For shipping operators in the Gulf, the practical question is whether a faster, cruise-missile-armed attack craft changes the threat envelope around large commercial vessels in the narrow waters between Bandar Abbas and the Omani coast. A 100-knot platform, if the Fars figure holds in service, would compress the warning time available to escort ships and merchant masters, and would extend the strike radius beyond what older IRGC fast boats have offered.

Markets and insurance

War-risk premiums for Gulf transits have remained elevated through the spring as incidents have multiplied. The 27 Rajab unveiling is unlikely to move premiums on its own without an operational deployment, but underwriters watching the sequence — parliament, live fire, vessel reveal — are pricing a posture that is hardening rather than de-escalating, even while talks continue.

Brent has traded in a wide range through May on the combination of diplomatic headlines and incident reporting. Traders contacted previously by this desk have said they are watching for two specific tells: any move that signals the 27 Rajab is being commissioned to the IRGC Navy rather than the regular fleet, and any Iranian parliamentary movement to operationalize the Strait Management bill beyond its current first-reading status.

Standing watch

Several questions remain open and this desk is standing watch on each.

The commissioning date for the 27 Rajab has not been announced. Iran has not published the cruise missile range, guidance specifications or warhead class. The chain of command for the vessel — IRGC Navy versus regular Iranian Navy — has not been confirmed publicly. It is also unclear whether the 27 Rajab is a single demonstrator hull or the lead of a planned class, a distinction with significant implications for the rate at which the Gulf threat picture could shift.

What is confirmed is the timing. With talks unresolved on frozen assets, the construction fund and sanctions relief, and with US officials continuing to signal that the military option remains in reserve, Tehran chose this week to put a new cruise-missile platform on a national stage. The diplomats and the admirals are working parallel tracks, and neither has slowed for the other.
