The Bo's'n's Whistle was a publication distributed to the employees of the Kaiser Shipyards in Oregon and Washington between 1941 and 1946. The first publication was released on July 18, 1941 under the editorial direction of Chick Johnson, and was given its distinctive name by Edgar Kaiser the General Manager of the shipyard. Subsequent issues released bi-weekly, along with a special issue on September 27, 1941 commemorating the launch of the "Star of Oregon". Distribution expanded to the Vancouver and Swan Island Shipyards in April 1942, with Hal Babbit, director of public relations for Kaiser Company serving as editorial supervisor.
The format of the Bo's'n's Whistle changed from a magazine to a weekly newspaper beginning March 10, 1944, with separate editions for each of the three shipyards - Oregon Shipyard, Swan Island, and Vancouver. On September 7, 1945 The Bo's'n's Whistle was again consolidated into one edition for all three shipyards, and on January 1, 1946 it was moved to a twice-monthly publication schedule. The final issue of The Bo's'n's Whistle was published on May 24, 1946. At its peak, The Bo's'n's Whistle was circulated to 90,000 employees, with over 4,000,000 copies distributed over its lifespan.
