AF-2S and AF-2W Guardians
One of the largest single-engine aircraft in Naval service, the AF-2W Guardian usually flew as part of a two-plane “hunter-killer” team, its role being the search for submarines (note the large radome) while the depth charge/rocket-carrying AF-2S Guardian attacked. With an 11-ton max takeoff weight, they had a 60-foot wingspan and 43-foot length. They were replaced by the “all-in-one” S-2 Tracker in 1955.
