Take Cover, trained by David Griffiths in South Yorkshire, became the seventh dual winner of the five-furlong contest last year when edging out Washington DC (Aidan O'Brien) and Goldream (Robert Cowell), to add to his success in 2014.
The son of Singspiel also went down by a head to Muthmir, from the Newmarket stables of William Haggas, in the 2015 Qatar King George Stakes.
Now a 10-year-old, Take Cover is set to attempt to create history in 2017 by becoming the first horse to win the Qatar King George Stakes three times. He ran an excellent race on his latest appearance when a fine fifth, beaten five lengths, in the G1 King's Stand Stakes over five furlongs at Royal Ascot on June 20.
Griffiths commented: "The plan is for Take Cover to go for the Qatar King George Stakes again.
"He ran a cracker in the King's Stand Stakes at Royal Ascot last week. I was chuffed to bits as it was probably the best renewal of the King's Stand that we have seen in the last few years and Lady Aurelia was a very good winner."
Godolphin's Profitable captured the Group 1 King's Stand Stakes at Royal Ascot in 2016 and was runner-up to Lady Aurelia in the same five-furlong race last week. His trainer Clive Cox has also entered Group 2 Temple Stakes scorer Priceless and Group 1 Commonwealth Cup sixth Tis Marvellous.
Other leading entries include King's Stand Stakes third Marsha (Sir Mark Prescott) and Group 3 Abernant Stakes victor Brando (Kevin Ryan), plus the last three winners of the Group 3 Bombay Sapphire Molecomb Stakes - Cotai Glory (Charlie Hills), Kachy (Tom Dascombe) and Yalta (Mark Johnston).
