In 1948, Venerable's short career in the Royal Navy came to an end when she was sold to the Netherlands and recommissioned as HNLMS Karel Doorman, replacing a smaller Nairana-class escort carrier of the same name while in Dutch service.

In 1955-58 she was rebuilt with an 8° angled flight deck, new elevators, new island, 40 mm anti-aircraft guns, steam catapult, and all new aviation facilities and electronics were fitted, including a Dutch-built new radar.

In 1960, during the Dutch decolonization and planned independence of Western New Guinea, a territory which was also claimed by Indonesia, Karel Doorman set sail along with two destroyers and a modified oil tanker to "show the flag".

She arrived in Fremantle, Australia, where the local seamen's union went on strike in sympathy with Indonesia; the crew used the propeller thrust of aircraft chained down on deck to nudge the carrier into dock without tugs.

In addition to her air wing, she was ferrying twelve Hawker Hunter fighters to bolster the local Dutch defence forces, which she delivered when she arrived at Hollandia, New Guinea.

[3] After the 1964 refit, Karel Doorman served the rest of her career mostly conducting NATO anti-submarine patrols in the north Atlantic, no longer carrying strike or fighter aircraft as part of her regular air wing.

For an invasion, the Indonesian Air Forces (TNI-AU) hoped to sink this aircraft carrier with Soviet-supplied Tupolev Tu-16KS-1 Badger naval bombers using AS-1 Kennel / KS-1 Kometa anti-ship missiles (six planes were intended for the attack on Karel Doorman).

Changing roles to a dedicated NATO antisubmarine warfare carrier, a wing of 8 Grumman S-2 Trackers and 6 Sikorsky S-58 ASW helicopters served aboard from 1961 until the 1968 shipboard fire and removal from Dutch service.
