1945: two-year-old season As a two-year-old, Airborne was extremely immature and failed to win in four starts, giving little indication of Classic potential,
1946: three-year-old season In Airborne’s three-year-old debut, he finished third in a moderate race at
Newmarket in April. Two weeks later, he returned to Newmarket and won a
maiden race over one and a half miles. The Derby of 1946 was the first to be run at Epsom since 1939, the course having been used as an
anti-aircraft battery position during the
war, and the race attracted a huge crowd, estimated at up to 500,000, including the
King and
Queen. Airborne, ridden by Tommy Lowrey, was an unconsidered outsider, starting at odds of
50/1 in a field of seventeen in a race run on soft ground. In the early stages, Airborne was held up and was still well back turning into the straight. Gulf Stream took the lead in the last quarter mile as Lowrey pulled Airborne wide to produce a sustained run down the centre of the course. He caught Gulf Stream inside the final furlong and won by a length. Airborne reappeared in the
Princess of Wales's Stakes at Newmarket in July where he took on older horses. He won his third successive race by beating the five-year-old
Hardwicke Stakes winner
Priam II. The following month, he ran at Newmarket for the fourth time that season and dead-heated with Fast and Fair in the Stuntney Stakes. At Doncaster in September, he started 3/1 favourite for the St Leger, which was run before another huge crowd. He tracked the leaders before being sent to the front in the straight and winning "in magnificent style" by one and a half lengths from Murren, with Fast and Fair third. It was a second win in the race for Perryman and Lowrey, who had been successful with Chamoissaire the previous year. On his final start of the season, Airborne was matched against the
Grand Prix de Paris winner
Souverain in the King George VI Stakes over two miles at Newmarket in October. Airborne started 4/5 favourite for a race which was publicised as an "international championship" for three-year-olds but finished third to the French colt, with the
Irish Derby winner Bright News taking second. Attempts to train Airborne as a four-year-old, with the
Ascot Gold Cup as his target, ended in failure, and he was retired to stud without racing again. ==Assessment==
