    U.S. forces and air-defense missile batteries across the Middle East were placed on high alert Jan. 7 in preparation for possible Iranian drone attacks, reports CNN, including all Patriot batteries and forces in the area.

    U.S. officials told CNN that intelligence mounted about a threat of an imminent attack against U.S. targets in the wake of the U.S. drone strike that killed Iranian general Qasem Soleimani. U.S. intelligence also observed Iran moving military equipment, including drones and ballistic missiles, over the last several days.

    The movement may be an Iranian effort to secure its weapons from a potential U.S. strike, or put them in positions to launch their own attacks.

    Iran has put missiles on its drones that have been used in other attacks, including a significant attack on Saudi oil installations last year (see below).

    Targets of concern are U.S. locations in Iraq, Kuwait, Saudi Arabia, the United Arab Emirates and Jordan.

    2019 Drone Tensions

    Drones forces from both sides targeted assets in 2019. In June, Iran shot down a U.S. military drone that it claimed was an intruding American spy drone entering its territory. The U.S. said the drone was shot down in international airspace over the Strait of Hormuz.

    In July, U.S. Marines jammed and destroyed an Iranian drone in the Strait of Hormuz from aboard the USS Boxer, an amphibious assault ship, because the drone has closed too close, to approximately 1,000 yards. Iran denied losing any of its drones.

    In September, Iran was blamed for an attack on the Saudi oil industry, with drones and cruise missiles assumed launched from an Iranian base in Iran close to the border with Iraq. The Abqaiq oil plant was struck by more than a dozen projectiles.

    Maritime Alert

    On Monday, the U.S. Maritime Administration issued an alert to commercial vessels operating in the Middle East, citing multiple maritime threats and stating “there remains the possibility of Iranian action against U.S. maritime interests in the region.”

    According to the alert, “The U.S. government is continually assessing the maritime security situation in the region to safeguard freedom of navigation, ensure the free flow of commerce, and protect U.S. vessels, personnel, and interests.

    “U.S. Fifth Fleet Naval Cooperation and Guidance for Shipping (NCAGS) has the latest information on the dynamic maritime security threats and operational environment in this region. U.S. commercial vessels are advised to exercise caution and coordinate vessel voyage planning for transits of the Persian Gulf, Strait of Hormuz, Gulf of Oman, North Arabian Sea, Gulf of Aden, and Red Sea with NCAGS and follow NCAGS’s recommendations and guidance whenever possible.”

  • GPS disrupted for maritime in Mediterranean, Red Sea

    GPS disrupted for maritime in Mediterranean, Red Sea

    The U.S. Maritime Administration issued an expanded advisory for GPS disruptions in the Middle East. The new advisory renews and repeats warnings for the eastern Mediterranean and adds the Port of Jeddah in Saudi Arabia.

    Reports have also been filed  with the U..S Coast Guard Navigation Center  about disruptions in Israel’s Port of Haifa and the Straits of Hormuz.

    Analysis by the Resilient Navigation and Timing Foundation and the non-profit firm C4ADS has also shown on-going disruptions in Russian waters of the Black Sea. Also, GPS jamming by Russia is suspected during a recent NATO exercise.

    The armed conflict in Syria has been blamed for much of the disruptions off of its shores.

    GPS jamming in support of illegal fishing is suspected by some as the cause of problems off of Port Said, and disputes over mineral rights has been suggested for the disruptions seen near Cyprus.

    Disruptions in the Black Sea are suspected to be security measures associated with the travel of Russian government officials.

    2018-014-GPS Interference-Eastern Mediterranean and Red Sea

    This revised advisory cancels U.S. Maritime Advisory 2018-007.

    Reference: U.S. Maritime Alerts 2018-004A, 2018-004B, 2018-008A.

    Issue: Multiple instances of significant GPS interference continue to be reported by vessels and aircraft operating in the Eastern Mediterranean Sea. These reports have been concentrated near Port Said, Egypt, the Suez Canal, and in the vicinity of the Republic of Cyprus. Additional instances of similar interference were reported in October 2018 near Jeddah Port, Saudi Arabia. This interference is resulting in lost or otherwise altered GPS signals affecting bridge navigation, GPS-based timing and communications equipment.

    Guidance: Exercise caution when transiting these areas. The U.S. Coast Guard Navigation Center (NAVCEN) and NATO Shipping Center websites contain information regarding effective navigation practices for vessels experiencing GPS interference. The information reaffirms safe navigation practices when experiencing possible GPS disruption, provides useful details on reporting possible GPS disruption, and is intended to generate further discussions within the maritime community about other disruption mitigation practices and procedures. This guidance also recommends taking note of critical information such as the location (latitude/longitude), date/time, and duration of the outage/disruption, and providing photographs or screen shots of equipment failures during a disruption to facilitate analysis. The NAVCEN information is available at https://go.usa.gov/xQBaU.

    Contact Information: GPS disruptions or anomalies should be immediately reported to the NAVCEN at https://go.usa.gov/xQBaw or via phone at 703-313-5900, 24 hours a day. The NATO Shipping Center has requested that instances of GPS interference also be reported to them using the format on their Cyber Interference link.

    Cancellation: This message will automatically expire on May 2, 2019.
