40 mm anti-aircraft Boffin gun. HAIDA has four of these in total. In RCN nomenclature, when a 40 mm Bofors gun was mounted on an Oerlikon mount, it was called a Boffin. In the slang of the United Kingdom, Australia, New Zealand and South Africa, boffins are scientists, engineers, and other people who are stereotypically seen as engaged in technical or scientific research. The Boffin had a rate of fire of 120 rounds per minute and a maximum vertical height of 23,300 feet.  (Photo by Jerry Proc)
