AN/ALQ-135
The AN/ALQ-135 is an electronic countermeasure (ECM) jamming system produced by Northrop Grumman for the Tactical Electronic Warfare Suite (TEWS) on F-15 Eagle and F-15E Strike Eagle aircraft. The system can jam and track multiple anti-aircraft missiles in addition to other threats. During the Gulf War, the AN/ALQ-135 logged more than 6,600 hours of combat, yet no aircraft were lost to a threat the system protects against.[1]
Development
Since the 1970s, the AN/ALQ-135 system has been a component of F-15 aircraft. The system has been continually upgraded. These upgrades include processor upgrades, durability upgrades, and weight reduction. Now the system is installed on more than 500 F-15s. The band 3 system was first installed in 1988. The band 1.5 system was first installed in F-15s in 2000.[1]
System Information
The modern system consists of five components of band 1.5 and band 3 equipment to cover the full spectrum of threats. The AN/ALQ-135 (v) system consists of the B3 RF Amplifier, B3 Control/Oscillator, B1.5 RF Amplifier, B1.5 Control/Oscillator, and the LRU-14.
The band 1.5 and band 3 equipment share 70% of their hardware. This means that logistics and maintenance are more easily performed. The band 1.5 and band 3 systems can jam both high band and low band threats.
