Summary:
The past week has seen a sharp escalation in the US–Iran conflict, culminating in the deadliest direct attack on US forces since hostilities resumed in early July. On 17 July, Iranian ballistic missile and drone strikes on Muwaffaq Salti Airbase in Jordan killed two US service members, left one missing, and injured several others, according to US Central Command. The announcement came as the United States completed seven consecutive nights of precision strikes against Iranian military targets across southern Iran, focusing on air defence systems, coastal surveillance sites, missile and drone facilities, logistics infrastructure, and maritime capabilities. Iran responded with further attacks on US military facilities hosted in Jordan, Bahrain and Kuwait, and damaged a Kuwaiti power and desalination plant. At the same time the United States reinstated and began enforcing a naval blockade of Iranian ports, disabling one tanker that attempted to reach Kharg Island and boarding another vessel to ensure compliance. Iran has formally suspended its commitments under the June Memorandum of Understanding, citing alleged US violations. The situation remains highly volatile.
Detailed Report
1. US Casualties in Jordan
In an official statement released on 18 July, US Central Command reported that two US service members in Jordan were killed in action on 17 July “as U.S. Central Command (CENTCOM) and partner forces defended against Iranian ballistic missile and drone attacks.” One service member was listed as missing. Four others were medically evacuated to Jordanian hospitals and later discharged.
These are the first confirmed US combat deaths from direct Iranian fire in the current phase of hostilities. Open-source monitoring, including geolocated footage and satellite fire data, indicated impacts and a significant fire at or near US positions at Muwaffaq Salti Airbase (also known as Al-Azraq) in Jordan. Footage circulated showing ballistic missiles appearing to strike the base after bypassing interceptors. CENTCOM confirmed that the Iranian attacks on 17 July formed the context for the US losses.
2. US Completes 7 Nights of Strikes on Iranian Targets
CENTCOM conducted precision strikes against Iranian military targets for seven consecutive nights through 17 July. The campaign resumed after Iranian attacks on commercial vessels in the Strait of Hormuz and the reimposition of a US naval blockade. CENTCOM has stated that the operations are intended to degrade Iran’s ability to attack commercial shipping and civilian mariners and to hold Iranian forces accountable for violations of prior understandings.
Target sets listed across successive CENTCOM releases included air defence systems, coastal surveillance and radar sites, missile and drone storage and launch facilities, naval capabilities (including Islamic Revolutionary Guard Corps small boats), command-and-control nodes, military logistics infrastructure, underground weapons storage, and maritime assets. Strikes employed fighter aircraft, drones, warships and other platforms.
Key developments across the seven nights included:
• Early nights focused on air defence systems, coastal radar sites, anti-ship missile capabilities, and large numbers of IRGC small boats in and near the Strait of Hormuz.
• Subsequent nights expanded to missile and drone storage sites, naval infrastructure, communication networks, and military logistics nodes along Iran’s southern coastline, including areas around Bandar Abbas, Bushehr, Chabahar, Qeshm Island and related locations.
• On 16 July CENTCOM confirmed the destruction of the Chah Bahar Shahid Kalantari Port surveillance tower in Chabahar. The command described the tower as part of an IRGC maritime surveillance network used for decades to track and target commercial vessels. CENTCOM stated that the strike “directly degrades IRGC’s ability to coordinate attacks on innocent civilian crew members” and supports freedom of navigation except for vessels attempting to violate the US blockade.
• Multiple road and rail bridges in southern Hormozgan province near Bandar Abbas were also struck. Iranian state media reported at least six bridges hit. These actions aligned with US targeting of military logistics infrastructure. Open-source reporting further indicated strikes on locations including Yazd, Lar, Bandar Abbas, Bushehr, Choghadak, Khorramabad, Ahvaz, Sirik and Qeshm Island in the later nights of the sequence.
Iranian officials claimed that some US strikes damaged desalination and power infrastructure in the Bunji/Jask area of Hormozgan province, disrupting water supply to roughly 20 villages. CENTCOM has maintained that its operations target military capabilities.
3. Naval Blockade Enforcement
CENTCOM resumed the naval blockade of vessels transiting to or from Iranian ports and coastal areas at 4:00 p.m. ET on 14 July. The blockade had previously operated from mid-April until mid-June and was lifted under the June Memorandum of Understanding.
On 15 July CENTCOM reported the first disablement of a vessel under the renewed blockade. Forces observed the Curaçao-flagged, unladen oil tanker M/T Belma transiting international waters toward Kharg Island, Iran’s primary oil export terminal. According to CENTCOM, the vessel ignored multiple warnings. A US aircraft then fired Hellfire missiles into the ship’s smokestack, rendering it inoperable. CENTCOM stated the ship was no longer transiting to Iran.
On 16 July, US Marines from the 11th Marine Expeditionary Unit conducted a verification boarding of the vessel M/T Wen Yao in the Gulf of Oman. CENTCOM released video of the operation and reported that, as of that date, American forces had redirected three commercial vessels attempting to run the blockade, disabled one that did not comply, and boarded one to ensure compliance. By 18 July the cumulative figures stood at five vessels redirected and one disabled.
4. Iran Targets US Facilities in Jordan, Bahrain, and Kuwait
Iran’s Islamic Revolutionary Guard Corps and Iranian Army claimed multiple ballistic missile and drone attacks on US military facilities hosted in Jordan, Bahrain and Kuwait. Iranian statements described the actions as retaliation for US strikes and warned that further US operations would expand the scope of Iranian responses.
In addition to the attacks on Muwaffaq Salti Airbase in Jordan that produced the confirmed US casualties, Iranian forces claimed strikes on facilities including Sheikh Isa Airbase in Bahrain and Ali Al Salem Airbase and Camp Arifjan in Kuwait. Kuwaiti authorities reported that an Iranian attack on 17 July damaged several power generation units at a power and water desalination plant, causing a fire and taking units offline. Kuwait depends on desalination for approximately 90 percent of its drinking water. Iranian statements also referenced the use of drones against radar systems, air-defence batteries, fuel storage and command nodes. CENTCOM assessed that many incoming threats were intercepted.
On 18 July, Iran’s Deputy Foreign Minister Kazem Qaribabadi announced that Iran had suspended its commitments under the June Memorandum of Understanding, citing alleged US failure to uphold its side of the understanding. Earlier Iranian parliamentary and Foreign Ministry statements had already described the memorandum as having entered a crisis phase or as effectively terminated. US officials have maintained that Iranian attacks on commercial shipping constituted the initial breaches of the arrangement.
Conclusion
The past week has seen a sustained intensification of military exchanges between the United States and Iran. US forces conducted seven consecutive nights of strikes aimed at degrading Iranian capabilities to threaten shipping in the Strait of Hormuz while enforcing a renewed naval blockade. Iran responded with missile and drone attacks on US facilities hosted in the region, producing the first confirmed American combat deaths of the current phase, and formally suspended its commitments under the June Memorandum of Understanding. Both sides continue to assert that their actions are defensive or retaliatory, and commercial transit through the Strait remains constrained.
