After the start of World War II, the subsequent fall of the Netherlands left the country's overseas territories without significant naval forces for protection. The Dutch East Indies harboured the majority of the Royal Netherlands Navy, the "West Indies" including the Dutch Caribbean and Suriname only had the gunboat HNLMS Van Kinsbergen for protection between them.

In order to help with patrolling of these waters, three former Norwegian whalers were hired and militarized. These were HNLMS Enern, HNLMS Femern, and HNLMS Toern.[1][2]
