ACE-72304 1/72 Grumman AF-2W Guardian Hunter US Navy Carrier Based Anti-Submarine Aircraft model kitThe AF Guardian was developed as a replacement for the Navy's TBF Avenger anti-submarine search & strike aircraft. The Navy ordered Grumman Aerospace Corpo ration to modify the developing XTB3F-1 bomber. The new plane was to be classified as "hunter-killer" carrier based anti-submarine (ASW) aircraft. The first prototype flew on 19 December 1945. Two variants of the Guardiar were produced: The AF-2S for torpedo or bombing missions and the AF-2W with the large ventral radar. Designed to work in pairs, the AF-2W "hunter" member of the team hac a crew of four and was unarmed, though it could carry underwing drop tanks, and had a large radome for the APS-20 search radar mounted on the belly under the cockpit. The finlets were to provide lateral stability, which was affected by the radome. The AF-2S "killer" member o1 the team had a crew of three and could carry up to 1,800 kilograms (4,000 pounds) of munitions, including depth charges, bombs, or a homing torpedo in the bombbay, plus 12.7 centimeter (5 inch) "high velocity ail rockets (HVARs)" mounted on underwing pylons. The AF-2S mounted APS-30 targeting radar in a pod under the right wing, a searchlight in a pod under the left wing, and coulc also carry sonar buoys
The Guardian was the biggest single-engine piston aircraft ever flown by the US Navy. It was driven by a P&W R-2800-48W Double Wasp radial engine, providing 2,40C horsepower to a big four-bladed propeller
A second version of the AF-2S hunter was built beginning in 1952, featuring "magnetic anomaly detector (MAD) gear with a boom on the right side of the fuselage. This variant was designated the "AF-3S", and 40 were built The last Guardian was rolled out in March 1953, with a total of 389 of all variants built, including the prototypes. By early 1953, Guardians began to be phased out of front line Navy squadrons in favor of the S2F-1 Tracker, a combined hunter-killer aircraft. August 31, 1955 saw the end of the last operational active Navy squadron. The Guardians had slowly been transferred to U.S. Navy Reserve squadrons and mothballed A number of Guardians ended up in civilian hands and were apparently used as "water bombers", and some of these aircraft are now on static display in museums.
