This revised advisory cancels U.S. Maritime Advisory 2019-006

1. Reference: U.S. Maritime Advisory 2019-004

2. Issue: The heightened military activities and increased political tensions in this region continue to present risk to commercial shipping due not only to this threat, but also due to the potential for miscalculation or misidentification. Additionally, vessels operating in the Persian Gulf and Gulf of Oman may encounter GPS interference and other communications jamming, which could occur with little to no warning.

3. Description: Following the May 12, 2019 attacks against four commercial vessels in the vicinity of the anchorage off Fujairah, UAE (see U.S. Maritime Alert 2019-002A) and the June 13, 2019 attacks against two additional commercial vessels transiting in the Gulf of Oman (see U.S. Maritime Alert 2019-003A), there is a continued possibility that Iran and/or its regional proxies could take actions against U.S. and partner interests in the region.

4. Guidance: U.S. commercial vessels operating in this area are advised to review U.S. Maritime Advisory 2019-004 and contact the U.S. Navy 5th Fleet NCAGS watch, per the below contact information, for additional guidance.
