What is the AH-64E Apache Guardian? Boeing’s Heavyweight Attack Helicopter, Explained
The AH-64E Apache Guardian is the U.S. Army’s frontline attack helicopter, built by Boeing at Mesa, Arizona. Forty years after the AH-64A entered service in 1986, the Apache remains the most-exported Western attack helicopter, with more than 2,800 airframes produced and 17 international operators. The current Echo model — also marketed as Apache Guardian — features improved engines, composite rotor blades, manned-unmanned teaming with the U.S. Army’s Gray Eagle drones, and integration with the new Israel Aerospace Industries Spike NLOS long-range anti-armor missile.

Combat record
- 1989 — Panama. First combat use (Operation Just Cause).
- 1991 — Desert Storm. Apache strikes opened the air campaign by destroying Iraqi early-warning radars on the night of 17 January. Some 277 Iraqi armored vehicles were destroyed by Apaches in the war’s 100 hours.
- 1999 — Kosovo. Task Force Hawk deployed Apaches but did not conduct combat sorties — a politically embarrassing episode.
- 2001–2021 — Afghanistan. Primary U.S. and UK / Netherlands close-air-support platform.
- 2003–2011 — Iraq. Multiple combat tours; one Apache (Lima 27) was shot down and the crew captured during the March 2003 Karbala raid.
- 2014–present — Iraq / Syria. Anti-Islamic State operations.
- 2009–present — Yemen / Saudi Arabia border. Saudi AH-64 operations.
- 2023 — Israel. Israeli AH-64 Saraf squadrons saw heavy combat use during operations in Gaza and southern Lebanon from 7 October 2023.
- 2024 — Red Sea. U.S. Marine AH-1Z and Army AH-64E operations against Houthi launchers from amphibious ships.
The Longbow radar and Hellfire
The mast-mounted Northrop Grumman AN/APG-78 Longbow millimeter-wave radar is the Apache’s distinguishing feature. The radar simultaneously classifies up to 256 ground targets, prioritizes them, and shares the picture with other Apaches in the formation via the IDM data link. The Longbow’s fire-and-forget AGM-114L Hellfire allows the helicopter to fire from defilade and reposition before the missile impacts.
Spike NLOS integration
In 2024 the U.S. Army accepted operational integration of the Israeli Rafael Spike NLOS (Non-Line-of-Sight) missile on the AH-64E. With a range of 32 km and a man-in-the-loop fiber-optic link, Spike NLOS extends the Apache’s reach far beyond Hellfire’s 11 km, allowing engagement from outside the threat envelope of modern point-defense SAMs like Tor-M2 or Pantsir-S1. The U.S. Army purchased 600+ Spike NLOS rounds in 2024.

Production today
Boeing’s Mesa line is producing Apaches at the highest rate in fifteen years, driven by foreign orders. Recent contracts include Poland (96 AH-64E), Australia (29), the UK upgrade to AH-64E Mk 1 (50), and a USD 1.95 billion U.S. Army re-manufacture program through 2030. Cumulative Apache production crossed 2,800 units in 2024.
Why the Apache matters
The Apache turned the rotary-wing battlefield in 1991 and has never relinquished its leadership. With the Spike NLOS integration restoring stand-off engagement against modern SAMs, the manned-unmanned teaming with Gray Eagle, and the 17-nation operator base, the AH-64E remains the global benchmark for the heavyweight attack helicopter. The Russian Mi-28NM and Ka-52M can claim more recent combat experience in Ukraine, but no rotary-wing strike platform outside U.S. service is as widely fielded or as densely integrated into Western joint operations.
