Two E-2A test machines were modified as prototypes of the E-2C, with the first flying on 20 January 1971. Trials proved satisfactory and the E-2C was ordered into production, with the first production machine performing its initial flight on 23 September 1972. The original E-2C, known as Group 0, consisted of 55 aircraft with the first aircraft becoming operational in 1973. They began arriving on carriers in the 1980s, serving until the 1990s when they were replaced by Group II aircraft in first-line service. Some ended up in the US Navy Reserve, being used to track drug smugglers. The type was also commonly used in conjunction with Grumman F-14 Tomcat fighters; monitoring airspace and then vectoring Tomcats over the Link-4 datalink to destroy potential threats with long range Phoenix missiles. The next production run, between 1988 and 1991, saw 18 aircraft built to the Group I standard. Group I aircraft replaced the E-2's older APS-125 radar and T56-A-425 turboprops with their improvements; the APS-139 radar system and T56-A-427 turboprops. The first Group I aircraft entered service on August 1981. Upgrading the Group 0 aircraft to Group 1 specifications was considered, but the cost was comparable to a new production aircraft, so upgrades were not conducted. Group 1 aircraft were only flown by the Atlantic fleet squadrons. This version of the E-2 was followed within a few years by the more-improved Group II, which had the improved APS-145 radar. Group II aircraft have been incrementally upgraded with new navigation systems, better situational display, and computerized electronics; culminating in the E-2C Hawkeye 2000 variant (sometimes called the Group III). A total of 50 Group II aircraft were delivered, 12 being upgraded Group I aircraft. This new version entered service in June 1992 and served with the Pacific and Atlantic Fleet squadrons. By 1997 the US Navy intended that all the front line squadrons would be equipped, for a total of 75 Group II aircraft.
