The NAVY 18 WP class is a class of patrol boat, designed by the Estonian shipbuilder Baltic Workboats.
Initially intended to patrol the waters of Estonia's exclusive economic zone (EEZ) as well as rapidly respond to potential maritime border intrusions, they also provided maritime force protection to NATO and partner countries' warships visiting Estonia at sea and in ports. The vessels can also be used for intelligence missions.
The WP class were ordered by the Royal Oman Police, with plans to use them for port security in 2022.
In April 2024, Estonia delivered two patrol boats to Ukraine.
