Centaur-class fast assault craft

The Project 58181 Centaur (Kentavr)/Project 58503 Centaur-LK[1] class is a series of small armored assault craft being built for the Ukrainian Navy. The first two vessels were laid down at the Kuznya na Rybalskomu in December 2016. The 58181 project was developed by State Research and Design Shipbuilding Center on the basis of the Gyurza-M class artillery boats, and the 58503 project number was assigned to the altered design used after construction of the first eight units began (by the contractor that oversaw their construction, PJSC ZLK.[1][2] Designed for carrying patrol service on rivers and coastal maritime areas, delivery and landing of marines.

Development and design
First Centaur during launching ceremony

The project 58181 was developed by State Research and Design Shipbuilding Center on the basis of the Gyurza-M class artillery boats in 2015. However, it was refined during construction. The first contract was signed in 2016.[3] On September 4, 2018, the first launching ceremony for the first boat of the first series was held. The boat was already built on a revised project, which received new project number 58503 and the code «Centaur-LK». On September 20, the second boat of the series was launched. On November 19, 2018, newly built assault boats arrived to Odessa to continue testing. The top speed of 50 knots is achieved by a pair of New Zealand-made Hamilton Jet water jet propulsion engines and can stay at sea for a maximum of five days.[4] The class is armed with two remote weapon stations with 12.7 mm high-caliber machine guns and a 40-mm rocket launcher. The boats also feature two 80-mm rocket-launch systems.

Failure of the first two units of «Centaur-LK» led to a criminal conviction, the halting of construction of future units (besides the third), and the Ukrainian Navy’s decision not to include the first two craft in its active combat fleet. As of March 2022, they have not yet joined its active combat fleet.[2][5]
