VOS-7
Observation Squadron 7 (VOS-7) (or VCS-7) was a United States Navy artillery observer aircraft squadron based in England during Operation Overlord. The squadron was assembled expressly to provide aerial spotting for naval gunfire support during the invasion of Normandy. Personnel and aircraft were assembled on 1 June 1944 and began flying missions on 6 June 1944. The squadron was disbanded when Allied capture of the town of Cherbourg ended naval bombardment responsibilities on 26 June 1944. It is thought to be one of the shortest-lived squadrons in the history of United States military aviation. Background. Catapult-launched Vought  OS2U Kingfisher and Curtiss SOC Seagull observation floatplanes traditionally carried aboard battleships and cruisers for artillery observers had been unable to survive Axis fighter planes during the amphibious invasion of Sicily. Faster and more maneuverable fighters were expected to provide more reliable observation of naval gunfire support during the invasion of Normandy. Fighters could reach the invasion coast from bases in England, and gunfire support warship availability would be increased by eliminating time required for launch and recovery of aircraft. Personnel and aircraft. Seventeen aviators were assigned from the VOS squadron detachments aboard the battleships , and and the heavy cruisers  , and . These naval aviators, commanded by the senior aviator from "Quincy", were trained by the United States Army Air Forces 67th Reconnaissance Group to fly Supermarine Spitfire Mk V fighter aircraft. VOS-7 is thought to be the only United States Navy Squadron flying Spitfires. Operations. VOS-7 was part of the air spotting pool for the Normandy invasion (the 34th Reconnaissance Wing of the RAF Second Tactical Air Force) commanded by Royal Navy Commodore E.C. Thornton. Use of drop tanks allowed missions of two hours with about 30 minutes transit time to the combat area, 45 minutes on station, and 30  minutes to return to base. Spotting missions flew in pairs. The spotter piloted the lead aircraft while his wingman watched for enemy fighters. Preferred altitude was , but overcast skies often limited visibility above . VOS-7 flew 191 (or 209) combat sorties beginning on 6 June. Ninety-four of those sorties were flown in the first three days. The senior aviator from "Tuscaloosa" was killed when his Spitfire was hit by flak on 6 June. Flak was responsible for most of the eight VOS-7 Spitfires destroyed by combat damage; but their pilots survived, as did the pilot of a ninth Spitfire destroyed  in a non-combat accident. Four VOS-7 pilots survived encounters with Messerschmitt Bf 109 and Focke-Wulf Fw 190 fighters. VOS-7 pilots were awarded nine Distinguished Flying Crosses and eleven Air Medals.
