Pretty cool 1934 photo showing Boeing F4Bs ready to take off from the carrier USS Saratoga. The Saratoga's sister ship Lexington was sunk in 1942, but the Sara survived the war. The 8-inch guns were removed during World War II and replaced with 5-inchers that were effective against aircraft. The F4B was gone within a couple of years after this picture.
I'm a bit puzzled by the markings on the F4Bs. Sara had two fighter squadrons (Fighting One and Fighting Six) with 36 total F4Bs. These two are from "Felix" which should be Fighting Six, but the rear F4B appears to be from a squadron designated 2 or 3.

Then again, the squadrons were frequently being redesignated or shifted between carriers. By 1941, it made a lot more sense, as the Saratoga (CV 3) embarked Air Group Three with Fighting Three, Bombing Three, Scouting Three and Torpedo Three.
As has almost always been the case, there are plenty of onlookers when flight operations are being conducted on an aircraft carrier.
