Acting on specific information received from overseas, the Sri Lanka Navy had zeroed-in on four LTTE ships about 2,800 km south east of Dondra on September 10 and 11, 2007. Although one of the four vessels, believed to be the largest ship operated by the LTTE had escaped, the SLN blew up three. The SLN subsequently tracked down the missing vessel and sank it about 2,600 km south of Dondra on October 7, 2007. The destruction of four ships within weeks had helped Sri Lanka to cripple the arms procurement network.
