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 attacks began the air campaign by destroying Iraqi early warning radars on the night of January 17. Approximately 277 Iraqi armored vehicles were destroyed by Apaches during the 100 hours of the war.
- 1999 — Kosovo. Task Force Hawk deployed Apaches but did not conduct combat flights — a politically embarrassing incident.
- 2001–2021 — Afghanistan. The primary close air support platform for the US and UK / Netherlands.
- 2003–2011 — Iraq. Multiple combat tours; an Apache (Lima 27) was shot down during the March 2003 Karbala raid and its crew was captured.
- 2014–present — Iraq / Syria. Operations against ISIS.
- 2009–present — Yemen / Saudi Arabia border. Saudi AH-64 operations.
- 2023 — Israel. Israeli AH-64 Saraf fleets saw extensive combat use during operations in Gaza and southern Lebanon starting October 7, 2023.
- 2024 — Red Sea. US Marines AH-1Z and Army AH-64E will conduct operations against Houthi launchers from amphibious ships.
Longbow radar and Hellfire
The Northrop Grumman AN/APG-78 Longbow millimeter wave radar mounted on the mast is the distinguishing feature of the Apache. The radar classifies, prioritizes, and shares up to 256 ground targets simultaneously with other Apaches in the formation via IDM data link. The AGM-114L Hellfire missile with Longbow’s fire-and-forget technology allows the helicopter to fire from cover and reposition before the missile strikes.
Spike NLOS integration
In 2024, the US Army accepted the 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 manned fiber optic link, Spike NLOS extends the Apache’s range well beyond Hellfire’s 11 km, providing engagement from outside the threat envelope of modern point defense SAMs (such as Tor-M2 or Pantsir-S1). The US Army purchased over 600 Spike NLOS rounds in 2024.

Current production
Boeing’s Mesa line is producing Apaches at the highest production rate in the last fifteen years, driven by overseas orders. Recent contracts include Poland (96 AH-64E), Australia (29), the UK’s upgrade to the AH-64E Mk 1 (50), and a $1.95 billion U.S. Army remanufacturing program through 2030. Total Apache production surpassed 2,800 units in 2024.
The Importance of the Apache
The Apache transformed 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.
