Northrop Grumman’s Multi-Role Electronically Scanned Array radar system has provided the E-7A Wedgetail with a next-generation capability, setting it apart from predecessors; now, continuous improvement is proving critical to counter emerging threats.
Operating as the airborne mission conductor within a wider network of systems, the E-7 provides operators with a comprehensive picture of the operational environment, enabling them to assess the landscape and direct fleet operations with precision.
Central to the E-7’s capabilities is Northrop Grumman’s Multi-Role Electronically Scanned Array (MESA) – a multifunction surveillance sensor that offers 360-degree coverage of the battlespace. MESA is capable of detecting, tracking and classifying a broad array of airborne, maritime and ground threats over long ranges. Its real-time data is critical for orchestrating fleet movements in dynamic situations.
A key feature of MESA is its combat identification technology, which differentiates friendly assets from potential threats and allows operators to manage operations at mission speed in rapidly changing environments. This flexibility maximises the effectiveness of allied forces and strengthens engagement decisions.
In collaboration with Boeing and the Royal Australian Air Force (RAAF), Northrop Grumman has recently enhanced MESA’s combat ID capabilities. These updates were integrated and flight tested using an operational E-7 aircraft at RAAF Base Williamtown – a testament to the technical maturity and mission readiness of the system. Rather than relying on simulations, the use of an in-service E-7 during these tests provided valuable real-world feedback on the advanced capabilities.
“Military operators require instant, precise identification data to make real-time decisions, especially as the battle landscape evolves at an exceptionally rapid pace,” said Ed Griebel, vice president of airborne surveillance programs at Northrop Grumman. “We’re modernising our multifunction sensor technology – including MESA – to deliver resilient capabilities swiftly and without disruption.”
Northrop Grumman’s commitment to digital transformation and advanced manufacturing, combined with rigorous testing practices, has allowed the company to scale production efforts and ensure that its systems perform reliably from the outset.
Griebel added, “MESA’s performance reflects our commitment to program execution within a digital ecosystem. Working seamlessly with our customers and suppliers ensures that our systems meet operational needs and work the first time, every time.”
The open systems architecture of both the E-7 and MESA enables ongoing enhancements and integration of feedback. As the E-7 continues to serve as a critical communications node for the joint force, its advanced sensing and interoperability are key to ensuring that fleet assets are where they need to be, when they need to be there.
Northrop Grumman, together with its customers and platform operators, is set to integrate these enhanced combat ID capabilities across current and future E-7 fleets. MESA is already in production for the US and Royal Air Forces and is actively fielded on E-7s serving the RAAF, as well as the Turkish and Republic of Korea Air Forces.
