General Characteristics and Role
The Grumman AF Guardian was the first purpose-built, carrier-based Anti-Submarine Warfare (ASW) system in the world. It was a large, single-engine aircraft that operated as a hunter-killer team consisting of two specialized variants flown in tandem: the AF-2W (Hunter), which carried the radar and detection gear to locate the submarine, and the AF-2S (Killer), which carried the ordnance to attack it. Developed for the US Navy in the late 1940s, it filled a critical gap in capability during the early Cold War era, where the threat of Soviet submarines was rapidly increasing. The Guardian was the last piston-engine aircraft designed for combat roles flown by the US Navy, preceding the shift to twin-engine jet and turboprop ASW aircraft.

Powerplant and Performance
- Engine: One Pratt & Whitney R-2800-48W Double Wasp 18-cylinder, air-cooled radial engine.
- Power Output: 1,864 kW (2,500 hp).
- Maximum Speed: 507 km/h (315 mph; 274 kn).
- Cruise Speed: 238 km/h (148 mph; 129 kn).
- Range: 2,415 km (1,500 mi; 1,300 nmi).
- Endurance: Up to 5.5 hours, necessary for long anti-submarine patrols.
ASW Equipment and Variants
- AF-2W (Hunter): Featured a large, distinctive radar dome (radome) under the fuselage containing the AN/APS-20 search radar, replacing the bomb bay. It lacked offensive armament.
- AF-2S (Killer): Carried the ordnance. Its large bomb bay could accommodate:
- Torpedoes (e.g., Mk 13).
- Depth charges (conventional or nuclear).
- Rockets (underwing hardpoints).
- Operational Use: Guardians primarily flew from the smaller Escort Carriers (CVEs) or early versions of modern carriers and were gradually replaced by the twin-engine Grumman S-2 Tracker starting in the mid-1950s.
