The following are ships of the Chinese FLEET (too big to be a flotilla) searching for MH370 in the area off Western Australia in the southern Indian Ocean. This is my estimate of ship names as at March 31, 2014. Note that complete accuracy is not assured as some ships may have left or not yet arrived. Its based on Chinese sources - not always accurate.
Qiandaohu Type 903 replenishment ship
Donghaijiu 101 rescue ship http://english.cntv.cn/2014/03/30/VIDE1396155241742200.shtml
To give an idea of the scale of the Chinese fleet, though some ship names differ today, connect with The Beijing Review, March 31. 2014, "Chinese Ships Convene for MH370 Search, Australian PM Applauds Assistance" http://www.bjreview.com.cn/se/txt/2014-03/31/content_610609.htm
