Development and design

Main article: Type 054A frigate

The Type 054A carries HQ-16 medium-range air defence missiles and anti-submarine missiles in a vertical launching system (VLS) system. The HQ-16 has a range of up to 50 km, with superior range and engagement angles to the Type 054's HQ-7. The Type 054A's VLS uses a hot launch method; a shared common exhaust system is sited between the two rows of rectangular launching tubes.^[1]

The four AK-630 close-in weapon systems (CIWS) of the Type 054 were replaced with two Type 730 CIWS on the Type 054A. The autonomous Type 730 provides improved reaction time against close-in threats.^[2]

Construction and career

Hengyang was launched on 23 May 2007 at the Hudong-Zhonghua Shipyard in Shanghai. Commissioned on 30 June 2008.

On 27 March 2013, Hengyang, Huangshan and Qinghaihu arrived in Grand Harbour, Malta.^[3][4]

Hengyang, Honghu and Yulin made a goodwill visit to Auckland, New Zealand in June 2017.^[5]

In late February 2025, the Hengyang along with the Type 055 destroyer Zunyi and the Type 903 replenishment ship Weishanhu traversed the Coral Sea and conducted live-fire exercises within Australia's exclusive economic zone in the Tasman Sea, disrupting several international flights between Australia and New Zealand, before continuing west to circumnavigate the entire continent of Australia. Their activities were monitored by both the Australian and New Zealand Defence Forces,^[6][7][8] with some Australian media labeling it "gunboat diplomacy".^[9]
