The Indian and Indonesian navies will conduct three-week-long coordinated naval patrols in the Andaman Sea in September 2007, ANTARA news agency reported. Two Indian naval ships, namely the Cheetah, a Landing Ship, and the Battimalv, a Fast Attack Craft, along with an Indian Naval Domier, will participate in the coordinated patrols, the Indian Embassy said in a press statement on Tuesday. The exercise will also be participated in by one Indonesian Naval ship and one Indonesian Naval aircraft. Besides carrying out patrols, the ships and aircraft of the two navies will also carry out exercises at sea to improve interoperability, it said. The coordinated patrols are conducted twice every year under a protocol signed by the two navies in August 2002.
