Just to clarify the discussion on the Battle "E" and Estocin awards. The Michael J. Estocin award was created by the attack community to recognize the best attack squadron in the Navy.
Back in the day, it could have been awarded to a single VFA squadron or a single VA (A-7) squadron, when they coexisted. It now is awarded to the best Strike Fighter squadron in the Navy. Duration of the award was one year. Each Naval avation community has similar awards (Intruder community had the McClusky award, the Hawkey community had the AEW excellence award, the Tomcat community had the Clfiton award, the Viking, Orion, Sea King and Seahwak Communities vied for the Arnold J Isbell award for undersea excellence as well as the Thach award (named for the Jimmy Thach) for the best ASW squadron in the Navy.
The Battle "E" is awarded to ships and aviation squadrons (1 from each type community for each coast (Pacific Fleet, and Atlantic Fleet). Here is a piece from the Tailhook Association for the awards for 2004, just to give everyone an idea (CNAL is Commander, Naval Air Force Atlantic, CNAP is Commander Naval Air Force Pacific, CNAF is Commander Naval Air Forces (who is also dual hatted as CNAP). The CNAF category is for those communities that have only 2 or 3 competing squadrons):
