## Summary

Iran's Islamic Revolutionary Guard Corps launched drone strikes targeting the US Navy's Fifth Fleet headquarters in Bahrain early Saturday, June 27, hours after the US struck Iranian missile and drone storage sites and coastal radar stations on June 26 in retaliation for the [Hormuz](/en/entity/strait-of-hormuz) attack on the M/V Ever Lovely. Bahrain's Foreign Ministry confirmed "a number of Iranian drones" targeted the country, calling it a "flagrant threat to security." Separately, a second vessel reported sustaining bridge damage from an unidentified projectile in the Strait of Hormuz, according to the UK Maritime Trade Operations authority; all crew were reported safe and no environmental damage was declared. The IRGC warned that any further US strikes would draw "broader" retaliation.

## The split

The US has not confirmed damage at the 5th Fleet base in Manama, and the IRGC statement is contested. Bahrain's government confirmed the drone attack but gave no casualty or damage figures. Iranian state media framed the strikes as a proportionate response to what it called a "blatant violation" of the US-Iran memorandum of understanding by American forces hitting Iranian coastal infrastructure. US Central Command framed its own June 26 strikes as a direct response to Iran's "unwarranted aggression" against commercial shipping, which violated the MoU. Each side claims the other fired first in the cycle that began with the [Ever Lovely attack on June 25](/en/n/hormuz-ever-lovely-attack-jun25).

## By the numbers

- 2, vessels now struck in the Strait of Hormuz within three days
- 0, confirmed casualties at the Bahrain 5th Fleet base as of initial reports
- ~20%, share of global oil supply that transits the Strait of Hormuz under normal conditions

## Why it matters

The US-Iran MoU, signed just days before the Ever Lovely attack, was already under severe strain. The IRGC targeting Bahrain, home to the 5th Fleet, marks a significant escalation in targeting: Iran is no longer just attacking commercial shipping but explicitly striking the principal US naval command hub in the Gulf. A confirmed casualty or a US decision to strike deeper into Iranian territory could push the conflict past the point where the MoU framework is salvageable. [Israel](/en/entity/israel) and the [Lebanon framework deal](/en/n/israel-lebanon-framework-deal-jun26) signed the day before face a direct spoiler risk.

## What to watch

- Whether the US conducts further strikes on Iran and the stated scope of any response
- UKMTO and CENTCOM damage assessments for the Bahrain base and the second tanker
- Oil price movement as the [Strait of Hormuz](/en/entity/strait-of-hormuz) remains contested
- Whether the US-Iran diplomatic channel stays open or breaks down entirely
