New F-15E Laser-Guided Rocket System: A Game-Changer in Counter-Drone Warfare

-


The U.S. Air Force has taken a significant step forward in aerial warfare with the latest modifications to the F-15E Strike Eagle. A recent test flight revealed the aircraft carrying an impressive 42 laser-guided rockets, marking a shift in drone and cruise missile defense strategies.

The Evolution of the F-15E's Arsenal

Traditionally, the F-15E Strike Eagle has been known for its versatility in air-to-ground and air-to-air combat. However, the emergence of unmanned aerial threats has necessitated a new approach. The integration of Advanced Precision Kill Weapon System II (APKWS II) rockets into the Strike Eagle’s arsenal is a game-changer. These 70mm Hydra rockets, equipped with laser guidance, offer a cost-effective and high-volume solution to counter drones and slow-moving aerial threats.


The Significance of the Test Flight

The recent test flight, conducted by the 96th Test Wing at Eglin Air Force Base, showcased the aircraft carrying six seven-shot rocket pods, totaling 42 rockets. This configuration allows for multiple engagement opportunities per sortie, significantly increasing the aircraft’s effectiveness in counter-drone operations.

Gabriel Myers, spokesperson for the 96th Test Wing, emphasized the importance of this development: "By working at speed to ensure advanced capabilities have the intended effects, we increase warfighter readiness and lethality."

Cost-Effective Defense Against Drone Threats

One of the standout advantages of the APKWS II rockets is their affordability. Compared to traditional air-to-air missiles like the AIM-9X Sidewinder ($450,000) or the AIM-120 AMRAAM ($1 million), the APKWS II guidance kit costs between $15,000 and $20,000. This makes them an economical yet highly effective solution for intercepting drones and subsonic cruise missiles.

Real-World Applications

The need for high-capacity aerial defense became evident during the April 2024 saturation attack on Israel, where F-15E crews reportedly exhausted their air-to-air missiles and had to rely on their M61 Vulcan cannon. The integration of APKWS II rockets ensures that future engagements will not be limited by missile supplies.

The F-15E Strike Eagle’s new laser-guided rocket arsenal represents a major leap forward in aerial warfare. With cost-effective, high-volume, and precision-guided capabilities, this modification enhances the aircraft’s ability to counter drone threats effectively. As drone warfare continues to evolve, innovations like these will be crucial in maintaining air superiority.

The Advanced Precision Kill Weapon System II (APKWS II) is a laser-guided rocket system designed to convert Hydra 70 unguided rockets into precision-guided munitions. Here are its key specifications:

  • Length: 73.8 inches (1.87 meters)

  • Diameter: 2.75 inches (70 mm)

  • Wingspan: 9.55 inches (24.3 cm)

  • Weight: 32 pounds (15 kg)

  • Speed: Up to 1,000 meters per second (Mach 2.9)

  • Range:

    • Rotary-wing aircraft: 1,100–5,000 meters (0.68–3.11 miles)

    • Fixed-wing aircraft: 2–11 kilometers (1.2–6.8 miles)

  • Guidance System: Semi-active laser homing

  • Circular Error Probable (CEP): Less than 0.5 meters

  • Warhead Options: M151 or Mk 152 10-pound high-explosive warhead

Boeing secured a $61.2 million contract from the U.S. Department of Defense to deliver additional High Altitude Anti-Submarine Warfare Weapon Capability (HAAWC) modules for the Navy’s fleet of P-8A Poseidon aircraft. This development marks a notable shift in the operational role of the Poseidon platform, transitioning it from a traditional maritime patrol aircraft to a more versatile strike-capable system. P-8A Poseidon. navair.navy.mil The HAAWC system is designed to enhance the deployment of the Mark 54 lightweight torpedo by enabling launches from cruising altitudes. This is achieved through a winged kit that includes foldable wings and a GPS-guided navigation unit, allowing the torpedo to glide toward its target before deploying a parachute for water entry. The system draws on technologies previously developed for the Joint Direct Attack Munition (JDAM) and the SLAM-ER missile, integrating lessons from long-range guided bomb programs. Operationally, the ability to launch torpedoes ...

KC-135 Stratotanker Modernization Plan Includes Drone Deployment Capability

-
Image
The U.S. Air Force’s FY2026 budget proposal includes a notable initiative aimed at enhancing the survivability and operational flexibility of its aerial refueling fleet, specifically the KC-135 Stratotanker. Originally developed in the 1950s, the KC-135 has long served as a cornerstone of the Air Force’s global refueling operations. However, the evolving nature of modern warfare—characterized by contested airspaces and advanced anti-access/area denial (A2/AD) systems—has prompted a reevaluation of the platform’s defensive capabilities. KC-135. 507arw.afrc.af.mil Central to this proposed upgrade is the integration of a Drone Delivery Mechanism (DDM), a system designed to deploy small unmanned aerial vehicles (UAVs) from the KC-135 in flight. This concept represents a shift from passive to active defense strategies for support aircraft. Traditional countermeasures such as chaff, flares, and infrared jamming systems like LAIRCM have provided limited protection against increasingly sop...

SPEAR 3 Missile: Revolutionary Stand-Off Weapon Set for Early 2030s Deployment

-
Image
The SPEAR 3 missile, a cutting-edge stand-off weapon designed for precision strikes, is now expected to enter service in the early 2030s. Developed by MBDA, this missile is intended to enhance the capabilities of the UK’s F-35B fighter jets, providing them with a long-range, high-precision strike option. SPEAR 3. MBDA Background and Development The Selective Precision Effects At Range (SPEAR) project began in 2006, aiming to create a series of air-launched stand-off weapons for the Royal Air Force (RAF). The SPEAR 3 missile, which shares components with the Brimstone anti-tank missile, is designed to engage mobile, fleeting, and re-locatable targets in all weather conditions, day or night.
