<p>Bofors 40 mm anti-aircraft guns on a Mk 12 quadruple mount firing on board <a href="https://en.wikipedia.org/wiki/USS_Hornet_(CV-12)" class="extiw" title="en:USS Hornet (CV-12)">USS <i>Hornet</i> (CV-12)</a>, circa February 1945, probably during gunnery practice.<br>
The original picture caption identifies the photo as having been taken during Task Force 58's raid on Japan, 16 February 1945. However, helmetless members of the gun crew, and rolled up shirt sleeves, strongly indicate that the occasion was in warmer climes and not while in combat.<br></p>
View looks aft on the port side, with the carrier's port quarter 5"/38 guns just beyond the 40 mm mount. Note ready-service ammunition and spent shell casings at right; men passing 4-round clips to loaders at left.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1">[1]</a></sup><sup id="cite_ref-2" class="reference"><a href="#cite_note-2">[2]</a></sup>
