UMS Inlay was built at Thanlyin Naval Dockyard near Yangon with the help of technical assistance and equipment provided by Singapore-based companies.

Launched in late November 2015, Inlay was commissioned in December 2017.

The OPV is capable of operating a helicopter from its approximately 17.5-metre (57 ft)-long flight deck and has a single hangar.

A stern ramp is fitted for a rigid-hulled inflatable boat.

The Inlay will supplement the two remaining Danish-built Osprey-class OPVs in service.
