cruiser Leyte Gulf responded to a distress call from Falcon Trader II reporting that suspected pirates in a small skiff were attempting to board the ship. A follow-up message reported that the pirates had boarded Falcon Trader II, but confirmed that her crew was safely in the ship's citadel. A SH-60F helicopter from squadron HS-11 embarked on Enterprise and a SH-60B helicopter from squadron HSL-48 on board Leyte Gulf were dispatched to investigate the situation. Once on the scene, the HS-11 helicopter fired warning shots at the suspected pirates in the skiff, prompting them to flee the scene. The helicopter pursued the skiff which was observed trying to rendezvous with a suspected pirate mother ship. The helicopter came under small arms fire, but the flight crew were not harmed while the helicopter maintained surveillance of the situation. On 25 March 2011, after determining there were no pirates aboard, Leyte Gulf sent a boarding party to Falcon Trader II to free its crew (pictured). On 16 May 2011, Bulkeley responded to a mayday call from the Panamanian-flagged, German-owned, very large crude carrier Artemis Glory. Bulkeley dispatched a SH-60B helicopter to the last reported position of the ship. Observing that a skiff carrying four men was firing upon Artemis Glory, the HSL-48 helicopter opened fire, killing four suspected pirates. Without any Navy or Artemis Glory casualties, the ship was able to continue to its next port-of-call.
