About the Northrop Grumman E-2 Hawkeye

The Northrop Grumman E-2 Hawkeye is the U.S. Navy's carrier-based airborne early warning and control aircraft, instantly recognizable by its 24-foot rotating radome mounted above the fuselage. First flown in 1960, the Hawkeye remains the only carrier-capable tactical airborne early warning platform in production, serving as the eyes of the fleet by detecting threats hundreds of miles beyond the range of shipboard radar. Its twin Allison T56 turboprops, the same engines that power the C-130 Hercules, give it the endurance to loiter on station for extended periods while coordinating air defense and strike operations.

The E-2's distinctive radome houses the AN/APY-9 radar in the latest E-2D Advanced Hawkeye variant, capable of tracking over 2,000 targets simultaneously and detecting low-observable cruise missiles against sea clutter. Operating from carrier decks imposes unique demands: the aircraft features folding wings, reinforced landing gear for arrested landings, and a tail hook rated for repeated catapult launches and arrested recoveries. Its operational ceiling reaches 37,000 feet, and it typically cruises at 260 knots with a combat radius exceeding 200 nautical miles from the carrier.

Beyond the U.S. Navy, the Hawkeye serves with France, Japan, Egypt, and Taiwan, making it one of the most widely exported American military aircraft. The type has seen continuous upgrades over six decades, with the E-2D representing a near-complete redesign featuring glass cockpit displays, satellite communications, and cooperative engagement capability that allows it to guide missiles fired by other platforms. No other aircraft combines carrier operations with the mission endurance and radar performance required for modern naval air warfare.
