was a fairly fast aircraft below and well-behaved as a trainer. Many of the British order of 524 Lightning IIs were fitted with stronger F-10 Allison engines as they became available, and all were given wing pylons for fuel tanks or bombs. The upgraded aircraft were deployed to the Pacific as USAAC F-5A reconnaissance or P-38G fighter models, the latter used with great effect to shoot down Admiral Yamamoto in April 1943. Robert Petit's G model named Miss Virginia was on that mission, borrowed by Rex Barber, who was later credited with the kill. Petit had already used Miss Virginia to defeat two Nakajima A6M2-N "Rufe" floatplanes in February and to heavily damage a Japanese submarine chaser in March, which he mistakenly claimed as a destroyer sunk. Murray "Jim" Shubin used a less powerful F model he named "Oriole" to down five confirmed and possibly six Zeros over Guadalcanal in June 1943 to become ace in a day. The British name was retained over Lockheed's original name 'Atalanta', the swift-running Greek goddess, following the company tradition of using mythological and celestial figures. Range extension The strategic bombing proponents within the USAAF, nicknamed the Bomber Mafia by their ideological opponents, had established in the early 1930s a policy against research to create long-range fighters, which they thought would not be practical; this kind of research was not to compete for bomber resources. Aircraft manufacturers understood that they would not be rewarded if they installed subsystems on their fighters to enable them to carry drop tanks to provide more fuel for extended range. Lieutenant Kelsey, acting against this policy, risked his career in late 1941 when he convinced Lockheed to incorporate such subsystems in the P-38E model, without putting his request in writing. Kelsey possibly was responding to Colonel George William Goddard's observation that the US sorely needed a high-speed, long-range photo reconnaissance plane. Along with a change order specifying some P-38Es be produced without guns, but with photoreconnaissance cameras, to be designated the F-4-1-LO, Lockheed began working out the problems of drop-tank design and incorporation. After the attack on Pearl Harbor, eventually about 100 P-38Es were sent to a modification center near Dallas, Texas, or to the new Lockheed assembly plant B-6 (today the Burbank Airport), to be fitted with four K-17 aerial photography cameras. All of these aircraft were also modified to be able to carry drop tanks. P-38Fs were
