📑 ➖➖➖ Đinh Tiên Hoàng (HQ-011) is the first Gepard-class frigate (Gepard 3.9 type) in the Vietnam People's Navy. The VPN contracted the Zelenodolsk shipyard in Russia to build the ship.
Đinh Tiên Hoàng (HQ-011) is designed to perform search tasks, track and destroy floating target ships, air defence, anti-submarine (limited), escort, and patrol territorial waters and special areas with economic rights. The ship can enter combat independently or in squadrons and is equipped with stealth technology, to present a minimum presence on enemy radar screens.
Vietnam and Russia signed a contract on 12 May 2006 worth USD $350 million to build two Gepard-class frigates designed by the Institute ZPKB in Zelenodolsk.
At the request of the Vietnam People's Navy the ship is known as Project 11661 was completely redesigned to become Gepard 3.9. The redesigned ships include stealth technology and the most advanced weapons available from Russia today, including air defence systems, Palma Close-in weapon system AK-630, Kh-35 anti-ship missiles, and Kamov Ka-27 helicopters. The anti-submarine technology includes the RBU-6000 anti-submarine rocket launcher. These two ships are the latest generation of the Gepard class produced at the Zelenodolsk plant. It took two years to build the prototypes under Project 11661.
Đinh Tiên Hoàng (HQ-011) was launched on 12 December 2010. The ship is named after Đinh Tiên Hoàng, the first Vietnamese emperor following the defeat of the Twelve Warlords. He was the founder of the short-lived Đinh Dynasty and a significant figure in the establishment of Vietnamese political unity in the tenth century.
