What is the AH-64E Apache Guardian? Explanation of Boeing’s heavy attack helicopter.
The AH-64E Apache Guardian attack helicopter is the U.S. Army’s front-line attack helicopter, manufactured by Boeing in Mesa, Arizona. After forty years since the AH-64A entered service in 1986, the Apache remains the most exported Western attack helicopter, with over 2800 airframes produced and 17 international operators. The current Echo model – also marketed as Apache Guardian – features improved engines, composite rotor blades, collaboration between manned and unmanned aircraft with the U.S. Army’s Gray Eagle drones, and integration with the long-range anti-tank missile Israel Aerospace Industries Spike NLOS.

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 100 hours of war.
- 1999 — Kosovo. Apache Hawk task force deployed but did not conduct combat flights — a politically embarrassing incident.
- 2001–2021 — Afghanistan. The primary platform for close air support for the U.S. and UK / Netherlands.
- 2003–2011 — Iraq. Multiple combat tours; Apache (Lima 27) was shot down during the Karbala raid in March 2003 and its crew was captured.
- 2014–present — Iraq / Syria. Operations against ISIS.
- 2009–present — Yemen / Saudi 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. U.S. Marine Corps AH-1Z and Army AH-64E will conduct operations against Houthi platforms from amphibious ships.
Longbow Radar and Hellfire
The Northrop Grumman AN/APG-78 Longbow millimeter wave radar mounted on the mast is the defining feature of the Apache. The radar classifies, prioritizes, and engages up to 256 ground targets simultaneously with other Apaches in formation via the IDM data link. The AGM-114L Hellfire missile with “fire and forget” technology allows the Apache to fire from cover and reposition before the missile strikes.
Integration of Spike NLOS
In 2024, the U.S. 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 beyond the 11 km of the Hellfire, providing engagement capability outside the threat range of modern air defense systems (such as Tor-M2 or Pantsir-S1). The U.S. Army purchased over 600 Spike NLOS rounds in 2024.

Current Production
Boeing’s Mesa production line is producing Apache helicopters at the highest production rate in the past fifteen years, driven by foreign orders. Recent contracts include Poland (96 AH-64E), Australia (29), the UK’s upgrade for AH-64E Mk 1 (50), and a $1.95 billion remanufacturing program for the U.S. Army through 2030. Total Apache production surpassed 2800 units in 2024.
Importance of the Apache
The Apache changed the battlefield with its rotary wings in 1991 and has never relinquished its leadership. With the integration of Spike NLOS, which restores the ability to engage remotely against modern air defense systems, the collaboration between manned and unmanned aircraft with Gray Eagle, and a pool of operators from 17 countries, the AH-64E remains the global standard for heavy attack helicopters. While the Russian Mi-28NM and Ka-52M can claim more recent combat experience in Ukraine, there is no rotary-wing strike platform outside of the U.S. service that is widely deployed or heavily integrated into Western joint operations.
