E2C

E2c, or E-2C in its military designation, is an acronym used in multiple contexts. There is no single, universally accepted meaning; the intended sense depends on capitalization, domain, and organization. The form E-2C is most widely recognized as a designation in aviation, while lowercase e2c is used as a brand name, code, or shorthand within various institutions.

The E-2C Hawkeye is a U.S. Navy airborne early warning and command and control aircraft developed by Grumman (now Northrop Grumman). It first entered service in the 1960s as part of the Hawkeye family, with the E-2C variant introduced later featuring upgraded radar, avionics, and communications. The aircraft is known for its distinctive rotating radar dome mounted above the fuselage and its role in maritime surveillance, air defense coordination, and battle management from aircraft carriers and allied fleets.

Other uses of e2c exist in branding, education, and technology contexts, where it may stand for program names, product codes, or partnerships. Because there is no universal definition, readers should determine the intended meaning from the specific source or domain in which it appears.
