L3 Technologies (Communication Systems-West) has been awarded a US$587.4 million contract for the engineering and manufacturing development of the Next Generation Jammer Low Band (NGJ-LB) system.
NGJ-LB is the latest product in the US Navy’s (USN’s) NGJ initiative which is an effort to develop a jammer which will engage radar threats transmitting across a 500MHz to 2GHz waveband and augment and replace the legacy ALQ-99 Tactical Jamming System on Growlers.
In service the NGJ-LB will complement the existing Raytheon AN/ALQ-249(V)1 Next Generation Jammer-Mid Band pod which covers a 2GHz to 6GHz waveband and is already in production.
Using the latest software and Active Electronically Scanned Array technologies, NGJ will provide enhanced AEA capabilities to disrupt, deny and degrade enemy air defence and ground communication systems.
The USN originally awarded the contract in 2020 but following multiple protests, the Navy issued an amended request for proposals in 2023 and this contract supports the final design efforts and manufacturing of operational prototype pods and system-level prototypes.
This latest increment will counter a larger capacity of adversary systems in the low-frequency electromagnetic spectrum. NGJ-LB is scheduled to reach early operational capability in 2029.
Growlers are used by the USN and the Royal Australian Air Force with the former leading the effort through the Airborne Electronic Attack Systems Program Office (PMA-234).
The Leonardo M-345 High-Efficiency Trainer (HET) basic/advanced trainer is similar to the M-346, which is the second part of the Italian Air Force’s training system, but is a substantially smaller and less powerful aircraft.

In Conversation... Shephard's Gerrard Cowan talks to CAE's Marc-Olivier Sabourin about how the training and simulation industry can help militaries achieve essential levels of readiness by leveraging new technology, innovative procurement methods and a truly collaborative approach.
As European countries increase their defence budgets, the Paris Air Show will look to how the aerospace industry’s responds, with programme progression, new technology and industrial partnerships all expected to take centre stage at Le Bourget.
The solution, named HTeaming, has already been tested in flight with a Spanish Navy H135 helicopter and an Airbus Flexrotor uncrewed aerial system (UAS).
