The artist, John Doughty, provides these comments on his work.  "As three A-4M Skyhawks from VMA-214, the 'Black Sheep' rise to altitude, they carry an arsenal that promises to bring any foe to their knees.  The 'Black Sheep', made famous in World War II with Pappy Boyington, continued their storied history through Korea and into Vietnam, where the 'Black Sheep' flew the A-4.  Having retired their A-4Ms for the new AV-8B Harrier, the 'Black Sheep' now fly out of MCAS Yuma, Arizona."
