[4] The Frogman Corps was established on 17 June 1957 based on the model of the United Kingdom's Special Boat Service, US Underwater Demolition Team, and Marinejegerkommandoen in Norway.

[6] King Frederik X of Denmark passed selection and completed continuation training to become a badged Frogman, in the course of which he earned the nickname "Pingo," when his wetsuit filled with water and he was forced to waddle like a penguin.

[10] On 5 February 2010, ten Frogman Corps members aboard HDMS Absalon (L16) conducted a counter-piracy mission in the Gulf of Aden approaching the Antigua and Barbuda-flagged merchant vessel Ariella by rigid hull inflatable boat which had been hijacked by six armed Somali pirates.

[11][12] They scaled the side of the ship and freed the 25 crew, who had locked themselves in a secure room, and continued to search the vessel for the pirates who had fled.

[12] In November 2021, a unit from the Frogman Corps was involved in counter-piracy operations in the Gulf of Guinea deployed aboard the Royal Danish Navy frigate HDMS Esbern Snare (F342).
