VAW-120, the E-2C fleet replacement squadron began receiving E-2D Advanced Hawkeyes for training use in July 2010. On 27 March 2014, the first E-2Ds were delivered to the VAW-125. The E-2D achieved Initial Operational Capability (IOC) in October 2014 when VAW-125 was certified to have five operational aircraft. This began training on the aircraft for its first operational deployment, scheduled for 2015 aboard . The E-2D will play a larger role than that of the E-2C, with five E-2Ds aboard each carrier instead of the current four C-models, requiring the acquisition of 75 total E-2Ds. On 11 March 2015, the "Theodore Roosevelt" Carrier Strike Group departed Naval Station Norfolk and returned to port on 23 November 2015, concluding the first operational use of the E-2D.
