China appears to be adding capacity to the vertical launch system (VLS) of its most advanced guided-missile frigate Type 054B under construction in Shanghai, satellite images show, allowing it to have a larger missile reserve and stronger anti-air defence capabilities. According to satellite images taken by US intelligence company Vantor on June 28, the VLS at the bow of a Type 054B vessel had a different shape compared to the first two Type 054B vessels that have already entered service. The previous version of the vessels had four eight-cell units, totalling 32 launching cells. However, the June 28 image showed a six-unit structure of what might be the same eight-cell system, allowing the new Type 054B vessel – which is still being outfitted at the Hudong Zhonghua shipyard – to carry 48 VLS cells.
