The Growler's value lies less in the airframe than in the fact that it is the only tactical jammer flying from carrier decks. Because it is a Super Hornet derivative, it keeps pace with the strike package it escorts, refuels from the same tankers and sits inside the same maintenance and logistics chain — an advantage the EA-6B never had. That commonality is also the constraint: the aircraft carries the same fuel and stores limits as an F/A-18F, so jamming pods, tanks and anti-radiation missiles compete for the same nine stations. Loadouts seen over Yemen, where Growlers flew with four AGM-88s in place of some pods, illustrate the trade-off between jamming and shooting.
The current transition is the most consequential change since the type entered service. The AN/ALQ-99 dates to the Vietnam era and is limited in power, reliability and frequency agility; the AN/ALQ-249(V)1 NGJ Mid-Band replaces it with AESA-based apertures able to place more power, more precisely, against more emitters at once. Mid-Band (Increment 1) reached IOC in December 2024 and has already been used operationally. Low Band (Increment 2), awarded to L3Harris in September 2024 after prolonged litigation, will not reach early operational capability before about 2029, leaving a period in which the fleet mixes new and legacy pods and retains ALQ-99 coverage at the low end of the spectrum.
Strategically, the Growler is the connective tissue between fourth- and fifth-generation air power: F-35s can survive contested airspace on signature alone, but non-stealthy strike aircraft, tankers and the carrier air wing's support fleet still need someone to suppress the sensors. Australia's purchase — 12 aircraft at Amberley, the only export fleet — gives a US ally a sovereign share of that capability and a stake in the NGJ programme, and it is one of the few areas where an allied air force operates a US Navy mission system on essentially the same schedule. The open question is reach: a pod-carrying tactical jammer must fly relatively close to the emitters it attacks, which is uncomfortable against long-range surface-to-air systems, and the Navy has no funded successor airframe. Whether stand-in effects migrate to unmanned platforms while the Growler shifts toward stand-off support is the central unresolved question about the type's next decade.
