The project 58181 was developed by
State Research and Design Shipbuilding Center on the basis of the s in 2015. However, it was refined during construction. The first contract was signed in 2016. 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. 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 6 February 2022, they had not yet joined its active combat fleet. Between then and April 2022, according to
Taras Chmut's reporting, they were accepted into active service. == Deployment ==
