Project history: Ordered for service in the Dutch East Indies, built by Higgins in New Orleans in MTB hulls, but with less powerful motors and replacement of torpedoes by anti-submarine armaments. Boats were transferred to Surabaya onboard of merchant vessels (last two carried, OJR5 and 6, were never commissioned).

Modernizations: None.
