Raytheon Intelligence & Space (RTX) has won a contract for low-rate initial production (LRIP) Lot I of the Next Generation Jammer Mid-Band (NGJ-MB) system.

The $171.6m deal furthers the programme from the development stage to production and deployment.

The latest award follows last month’s Milestone C approval from the Navy for Research, Development and Acquisition for the NGJ-MB programme.

NGJ-MB has finished more than 145 hours of developmental flight testing on the EA-18G Growler using mission systems and aeromechanical systems.

It has also completed more than 3,100 hours of chamber and lab testing at Naval Air Station Patuxent River in Maryland, and Naval Air Station Point Mugu in California, US.

Besides jamming techniques and reliability testing, these tests also evaluated the system’s performance both on and off the Growler aircraft.

NGJ-MB is the US Navy’s advanced electronic attack system.

It is designed to tackle both advanced and emerging threats by leveraging the latest digital, software-based, and Active Electronically Scanned Array (AESA) technologies.

These features in the system enable operators to ‘non-kinetically attack’ more targets at larger distances.

The attack system ‘offensively denies’, disrupts and degrades enemy technology, including air-defence systems and communications.

RI&S Electronic Warfare Systems vice-president Annabel Flores said: “With its power and ability to jam multiple radars simultaneously, NGJ-MB will fundamentally change the way the Navy conducts airborne electronic attack.

“NGJ-MB will increase the survivability and lethality of fourth-and fifth-generation fighters, making naval aviation that much more effective.”

In August 2020, NGJ-MB completed its first flight test on the EA-18G Growler aircraft.
