During 21–23 October, the EssexExpeditionary Strike Group provided humanitarian assistance and disaster relief to the Philippines after the Super Typhoon Juan caused extensive destruction to municipalities along the eastern coast of the Province of Isabela. The crew was awarded the Humanitarian Service Medal.
2011
At the request for assistance from the Japanese government, the Navy directed Essex to be deployed off the northeastern coast of Honshu after the massive 2011 Tōhoku earthquake and tsunami. The ship was involved in relief activities in the Sea of Japan off Akita Prefecture. Helicopters from the ship helped deliver relief supplies to quake and tsunami survivors along the northeast coast of Tohoku. The ship departed Sasebo in September 2011 for a patrol of the western Pacific. Accompanying the ship were the landing ships and. In November, a Petty Officer 1st Class was fatally injured aboard Essex during a weapons systems test while the ship was off the coast of Bali. A command report released in early 2012 cited "breakdown of safety procedures, protocol violations and gross negligence".

While Essex was scheduled to depart for Cobra Gold 2012, an annual exercise with Thailand, her participation was canceled due to maintenance issues. It was announced in January 2012 that Essex would be returning to her former home port of San Diego, California, after 11 years of forward-deployment in Japan. Before departing for San Diego, the Essex crew will perform a hull swap with the crew of fellow Wasp-class sister-ship, Bonhomme Richard, to continue their deployment to Sasebo, but aboard the newly arrived ship.
Collision with USNS ''Yukon''
On 16 May 2012, Essex suffered an apparent steering failure while approaching for an underway replenishment. The two ships collided causing damage to both ships. There were no injuries and no loss of fuel was reported. Both ships were able to continue to San Diego under their own power. On 19 June 2012 the Navy announced that the ship's commander, Captain Chuck Litchfield, had been relieved of command due to "loss of confidence in his ability to command." An investigation determined that the collision was avoidable and caused by improper supervision by Litchfield over his junior bridge crew. Although Essexs steering had failed, the investigation determined that better leadership by Litchfield could have prevented the collision. The investigation recommended administrative action against Essexs executive officer, officer-of-the-deck, conning officer and helm safety officer. Essex entered Naval Base San Diego for an 18-month maintenance and upgrade on 18 September 2012.
