Captain George Francis Kosco (1 April 1908 – 11 June 1985) was a United States Navy aerologist and polar explorer.

[1] Kosco graduated from the United States Naval Academy in 1930, and earned a master's degree in weather aerology from the Massachusetts Institute of Technology in 1940.

[3] His dissertation, co-authored with John O. F. Dorsett, was called Winter weather types of the eastern North Pacific and adjacent coastal and island areas.

[6] Bob Drury and Tom Clavin describe him as a "handsome, athletic six-footer",[5] while Buckner F. Melton Jr. calls him "a slightly stout moon-faced officer".

Kosco later admitted to a board of inquiry that he had underestimated Cobra's strength, "basing his prediction on historical data about regional storms rather than relying upon current local observations."
