Interesting note from the German Navy Blog, “Marine Forum”
“10 February, PAKISTAN, Opening ceremony in Karachi for Pakistan-hosted multinational naval exercise „Aman 2017“ … until 14 Feb, three phases in and off Karachi: in-port, at-sea maritime, anti-terror (special forces/naval infantry) … participants from 37 countries, 9 of which with naval units … 24th Chinese task group (destroyer „Harbin“, frigate „Handan“, replenishment ship „Dongpinghu“), Russian Northern Fleet task group (destroyer „Severomorsk“, tanker „Dubna“, salvage tug „Altay“), USA with patrol boat „Typhoon“, AKE „Amelia Earhart“ plus two USCG vessels (emphasis applied–Chuck) … frigate „Arunta“ (Australia), frigate „Sultan Iskandar Muda“ (Indonesia), OPV „Samudra“ (Sri Lanka), frigate „Gelibolu“ (Turkey), destroyer „Daring“ (UK) … and, of course, hosting Pakistan Navy”
I can only think that since the Navy PC “Typhoon” is there, the two USCG vessels might be 110s out of Bahrain. Kind of surprising we have not seen any press releases on this.
