Airplane UUSN Lockheed P2V-5 Neptune 12" Wood Model Aircraft The P2V-5, which first flew on Dec. 29, 1950, was the most-produced version of the Neptune. The P2V-5 replaced the nose cone in earlier versions with a turret, and included an APS-20 radar and enlarged wing tip fuel tanks. The Neptune could carry up to 8,000 pounds of mines, torpedoes, bombs or depth charges, and had a range of almost 5,000 miles. The Neptune was never carrier based, but operated from land only. Prior to the introduction of the P-3 Orion in the mid 1960's, the Neptune was the primary land-based anti-submarine patrol craft, intended to be operated as a the hunter of a '"Hunter-Killer" group, with destroyers employed as killers. In addition to the US Navy, the P2V-5 served in Argentina, Australia, Brazil, Great Britain, The Netherlands and Portugal.
