White Heather (ホワイト・ヘザー号 Howaito Hezā-gō) is a civilian ship whose crew was hired by Alfred to guide the Aryan Socialist Union to the Indian Ocean for a salvage mission.

White Heather is a large ship with three masts and a white hull with a red-painted waterline. On her lowered stern is a small salvage arm, and on her large bridge is a gray radar mast.

In late 1994, when a French telecommunications company discovered the shipwreck of U-234, a WWII Nazi U-boat, Alfred was concerned about the concurrent dispute of the waters since one party would eventually discover the painting "The Twelve Knights Led by Brunhilda" at the bottom of the ocean. Specifically, the painting was one of four pieces that contained financial account numbers of the Schutzstaffel 's finances to aid Nazi refugees after they fled Nazi Germany near the war's end. Having already been sought out by Rachmann to fund the Aryan Socialist Union, a neo-Nazi political party in the United States, Alfred agreed to fund his group if he passed his test to retrieve the painting. To aid the neo-Nazis, Alfred gave them caches of weapons and also lent White Heather to them so that they could sail to the Indian Ocean.

In March 1995, the White Heather 's civilian crew agreed to sail the neo-Nazis to the salvage site near the Nicobar Islands. Near the salvage site, the neo-Nazis spotted the Black Lagoon above the U-boat's location. Radioing to Black Lagoon, White Heather requested that the pirates identify themselves and their mother ship since Dutch claimed to be affiliated with the Thai Navy. When Dutch responded that his mother ship's location was "classified information," White Heather cut communications, and her crew confirmed that Black Lagoon was not part of any military vessels in the area. Once Blitz Stanford reported the imposters to Rachmann, he ordered his men to set up the TOW missile launchers on deck. Without warning, the crew fired two TOWs at the Black Lagoon, forcing them to leave the salvage site.

Before the neo-Nazis began their mission, Rachmann gathered his men on deck and chose Kruppen Feller to lead the diving team, then holding a brief marching rally with the neo-Nazis' anthem. Setting up the diving pod, Kruppen Feller and several neo-Nazis began to disembark and descend while Feller gave a Hitler salute. As the crew waited on the ship, the neo-Nazis below clashed with Revy and Rock, the latter of which accidentally let the painting fall into the neo-Nazis' possession. After quickly ordering Streicher to emerge to the ocean surface, Kruppen Feller reported back to White Heather and Rachmann that he had the painting. Seeing one of the divers outside the pod getting shot by Revy, Kruppen Feller warned the crew to shoot the thieves when they emerged. Preparing a heavy machine gun, one neo-Nazi waited until Revy emerged and shot at her. In response, Revy tried to use her less-powerful underwater rifle, but Rock pulled her into the water knowing that the neo-Nazis' firepower would decimate her. Smugly looking over the railing, Rachmann boasted that the pirates should not have tried to plunder the "sacred gravesite," and White Heather began to sail away.

At night, her civilian crew remained in the bridge while the neo-Nazis began to celebrate. In his office, Rachmann admired the painting while Stanford politely questioned why they used such abundant resources just to secure one painting. Smiling, Rachmann answered that their group's funder Alfred spoke about how the painting would bring meaning to their U.S. political party, adding that Alfred was a secretive man since he was wanted by "Zionists." While the neo-Nazis partied, Revy and Dutch went onto a small Zodiac motorboat to raid the White Heather and steal back the painting. While walking outside, a patrolman noticed the grappling hook on the railing, but before he could yell for help, Revy pointed her pistol at his head and shot him, alerting the neo-Nazis. In the anime, the neo-Nazis initially thought that the gunfire was celebratory, not hostile. Subsequently, both Revy and Dutch managed to kill many neo-Nazis on board, although Dutch was sidetracked when he noticed that Revy tried attacking non-combatant civilian sailors of White Heather. In the manga, Revy killed all the civilian sailors of White Heather. As Dutch berated Revy on deck, the remaining neo-Nazis tried to sneak up on them, but both pirates turned their guns in opposite directions and killed their would-be attackers.

While Dutch went to look for Rachmann, Revy was confronted by an arrogant Blitz Stanford, who bragged about his customized Luger firearm. When Stanford began to explain the gun's features and declared that Revy should have been scared, the female gunslinger was not intimidated at all and shot him in the middle of his speech. Furious that she attacked him in a "dishonorable" manner, Stanford cursed Revy as a coward before she gleefully killed him. At the same time, Rachmann called Alfred to assure the latter that the assault on the ship would result in the ASU's victory, but Alfred was unconcerned with his apology. At that point once Revy killed Stanford, Alfred heard the gunshot over the phone and calmly assessed that the battle was over for Rachmann, who was terrified to see Dutch enter his office. Impressed that the African-American Dutch bested the white Rachmann, Alfred requested that he be put on the phone. The old man apologized to Dutch for putting on a "shameful display" of henchmen, and Dutch asked rhetorically asked him if he actually wanted something inside the painting and if he had the Lagoon Company's office number. In the anime, Rachmann thought that the painting was a work of Adolf Hitler, but the artist was a much lesser-known name. Subsequently, Alfred confirmed Dutch's conclusions, relaying to him and Rachmann the history of the painting and its ulterior significance as well as hiring both sides to test Rachmann's capabilities, infuriating Rachmann.

In response to Rachmann's rage and accusation of betrayal, Alfred sternly reminded the neo-Nazi that he gave large financial backing and weapons to the Aryan Socialist Union and yet could not take on the small pirate company. When the SS officer called Dutch a racial slur, the latter jokingly retorted that he could just throw the painting into the sea. Unconcerned, Alfred concluded that he did not care what Dutch did with the painting so long as it was not discovered by other parties. Annoyed, Dutch calmly replied that he only wanted the money as promised. At that point, Dutch and Alfred nonchalantly wished death upon each other and ended the call. Immediately, Revy arrived and gave her pistol to Rachmann as an opportunity for him to commit suicide, but the distraught Rachmann instead turned the gun on Dutch only to discover that there were no bullets inside. Shocked, Rachmann remained frozen as the two pirates laughed and shot him dead. Out on deck, Dutch used a flare gun to signal to Benny to pick them up. While waiting for Black Lagoon to pick her up from White Heather, Revy claimed that she could not work with Rock due to his contrasting attitude.
