Hello all. I was wondering if anyone had any info or resources where I might find something regarding a APFSDS round for the Bofors 57mm L/70 Naval cannon that was apparently developed in the 1970s for the 57x438R calibre . I came across some old defense readings from the 1970s that mentioned a apfsds round was designed and tested by Bofors for the 57mm L/70 Mark 1 Naval cannon. With my limited understanding I don't know where to begin looking into this round/subject, my resources at hand have netted me nothing so far . I checked a number of Naval publications and tried to reach out too BAE Systems which bought Bofors from my understanding but have yet to receive a reply. Thanks in advance. Lutalica
So this is going to be my thread in regards to Canadian Warships. I'll start with the current navy, and hopefully, sooner rather than later, I'll get my hands on some info for the CPF/Tribal replacement.
