During their 189-day mission in the Gulf of Aden and Somali waters, the two frigates rescued one ship from onboard pirate attacks and another nine from pirate pursuits.

The flotilla escorted 578 vessels to protect them from pirates in the region. The team also escorted ships used to evacuate Chinese citizens from Libya.

Prior to the ships' return, the team visited Tanzania, South Africa and the Republic of Seychelles, and stopped over at Singapore.

The frigates set sail for the Gulf of Aden on November 2, 2010.

The Qiandaohu, a supply ship previously with the 7th escort force, was ordered to continue its mission with the 8th squad.
