Can anyone explain the purpose of these three ramps on either side of the stern on the aircraft carrier the USS Midway?
Those are EOD jettison ramps. (Explosive Ordinance Disposal) They are in many locations around the flight deck. A bomb/missile could be "cooking off", it may have been exposed to prolonged jet exhaust, fire, or any number of factors, any of which lead to the urgent need to get it overboard (jettison it) with the quickness.
