Air Force Blue features among 17 horses confirmed at the five-day entry stage for the Qipco 2000 Guineas at Newmarket on Saturday.
Aidan O'Brien's star colt is odds-on to take the first Classic of the season following a stellar juvenile campaign that saw him win three Group One races - the Phoenix Stakes, the National Stakes and the Dewhurst.
O'Brien has three other possibles as he seeks to take the Classic for a record eighth time.
Godolphin suffered a blow when their main hope Emotionless was ruled out of the race, but they can still mount a decent challenge, being represented by the Mark Johnston-trained Buratino, Jim Bolger's Herald The Dawn and Ribchester, trained by Richard Fahey.
Massaat, runner-up to Air Force Blue in the Dewhurst, will be Owen Burrows' first Classic runner after he took over from Barry Hills.
His owner Sheikh Hamdan Al Maktoum also has Taqdeer, trained by John Gosden.
Peter Chapple-Hyam relies on his Racing Post Trophy victor Marcel, while Ed Walker looks to Stormy Antarctic following his convincing victory in the Craven Stakes over the course and distance earlier this month.
The list of possibles is completed by Blue De Vega, First Selection, Galileo Gold, Kentuckyconnection, Zhui Feng and Zonderland.
