Primary Readiness and Training Staff
Although Commander, Carrier Strike Group (CSG) 4 was established on on April 29, 2014, the command was initially activated as Carrier Division 4 as an element of the U.S. Pacific Fleet on March 13, 1943. Following World War II, the command transferred to the U.S. Atlantic Fleet and became a major contributor to organizing a post-war Navy. In July 1973, Carrier Division 4 was re-designated as Commander, Carrier Group (CCG) 4 and was responsible for facilitating the Navy's transition from a traditional battle force to a modern-day carrier strike group concept that emphasized a commander's responsibility for a whole carrier strike group.
In 1984, Carrier Group 4 began working as the primary readiness and training staff for the U.S. Atlantic Fleet. In 1985, two events let to new concepts of tactical operations for carrier battle groups: when USS Yorktown (CG 48) conducted the first live missile fire that included command, control and target tracking platform different than the missile-firing ship and when USS America (CV 66) successfully conducted the first carrier flight operations in a Norwegian fjord during NATO exercise Ocean Safari 85.
From 1987 to 1989, the command continued to conduct advanced phase training operations for East Coast assets in preparations for deployments and exercises. In response to Operation Desert Shield, the command successfully certified to carriers and their air wings for deployment on short notice in February 1991. During this time, the command was given the additional responsibility of conducting joint operations aimed at interdicting the flow of narcotics from South America.
In October 2004, CCG-4 was redesignated as Commander, Strike Force Training Atlantic (CSFTL) as the Atlantic Fleet integrated training lead tasked to enable, mentor and assess integrated tactical training in order to ensure the warfighting of East Coast naval forces. Administratively aligned under CSFTL are Tactical Training Group Atlantic (TTGL) and Expeditionary Warfare Training Group (EWTGL).
Today, CSG-4 trains carrier strike groups and independent deployers primarily during a composite training unit exercise (COMPTUEX), force protection exercises and joint training force exercises (JTFEX) off the eastern seaboard of the U.S. They also train amphibious ready groups (ARGs) with embarked Marine Expeditionary Units (MEUs) as well as other surface combatant commands.
