From Defense Media Network:

The Prowler flew its last deployment with the “Garudas” of VAQ-134 aboard USSGeorge H.W. Bush (CVN 77) in November 2014. It is being replaced by the EA-18G Growler, more often called the Grizzly in order not to be confused with the EA-6B during flight operations. While the Navy is retiring the Prowler, plans are for it to remain in service with the Marine Corps until at least 2019.
