English: CV-17 USS Bunker Hill after Kamikaze attack on 11 May 1945. The Kamikaze pilot (Kiyoshi Ogawa) and his bomb smashed through the flight deck, but did not make it through the hangar deck where it exploded. Bunker Hill's armor protecting the machinery spaces below had proven effective. A significant improvement of the USS Bunker Hill (as an ESSEX Class ship) over the other US carriers at the time was that they were equipped with a more heavily armored deck, plus a second armored deck on the hangar level designed to detonate bombs before they reached the vital machinery and electronic spaces below.
