Grumman AF-3S Guardian

During the 1950s, the AF-2 Guardian anti-submarine aircraft were operating from the U.S. Navy carriers in so-called Hunter-Killer pairs which consisted of one machine of the AF-2W version performing the Hunter role using its volumous, belly-mounted AP-20 search and early-warning radar to locate enemy’s submarines while the other member of the team was an AF-2S which was the Killer, carrying a variety of offensive anti-submarine weapons, such as torpedoes, depth charges or rockets in the bomb bay or beneath its wings.
