The E-2 Hawkeye is the Navy's all-weather, carrier-based tactical battle management airborne early warning, command and control aircraft. Forty eight E-2Ds have already been delivered to the USN with an additional 4 by the end of 2021 and another 78 by 2025. The Advanced Hawkeye will replace all 75 USN E-2C aircraft. The older E-2C and the new E-2D look very similar on the outside but the inside is a complete rebuild. Japan has received 3 of their 9 E-2Ds and orders from France.

The first E-2D flew in 2007 with new electronics, communications, new Rolls Royce engines, a glass cockpit and radar. VAW-121 “Bluetails”, an Airborne Early Warning squadron that was established in 1967 and based at NAS Norfolk. After 37 years of operating the E-2C Hawkeye the VAW-121 began to use the E-2D Advanced Hawkeye. E-2D c/n AA18 serial 168599 was manufactured in 2015. During 2018 VAW-121 was assigned to the USS Abraham Lincoln CV-72. In 2019 they sailed to the Middle East.
