Northrop Grumman will manufacture initial production units of AN/APR-39E(V)2 RWR for the US Army under a five-year contract announced on 11 March.
The AN/APR-39E(V)2, previously known as the Modernized RWR, will provide an improved level of precision in detecting, locating and identifying threats by combining the company’s digital receiver exciter architecture with new digital signal processing algorithms, its manufacturer claimed.
The AN/APR-39E(V)2 is a fully digital RWR with the instantaneous bandwidth and frequency coverage to protect against what Northrop Grumman described as “advanced radar threats”.
The system has an open architecture design to allow growth to future electronic warfare capabilities and uses a smart antenna and advanced processing to detect a broad range of radio frequency threats.
Another design feature noted by the company was its readiness to be the survivability suite controller in multi-domain, large-scale combat operations. The system, the company said, was capable of sharing threat data, enhancing survivability and mission effectiveness.
In March 2019, Northrop Grumman announced it had received an award from the US Army to develop the AN/APR-39E(V)2, which has become the latest in the large family of RWRs. There are more than 6,000 RWRs in service with US forces and hundreds have been in service with forces from Sweden, Qatar, Saudi Arabia, Egypt and South Korea.
An evolution of the Tekever AR3, the AR3 EVO that broke cover at DSEI incorporates the thousands of incremental evolutions the company has implemented through its spiral development, geared towards delivering a constant stream of improved aircraft to Ukraine.
The new capabilities are based on platforms already in use or in development, and are designed to perform in demanding defence missions.
In an era of rapidly evolving threats, where drones, cruise missiles, and ballistic salvos redefine the battlefield, IAI‑ELTA Group stands at the forefront with its revolutionary radar technology. At the heart of this technological leap lies the ELM-2084 Multi‑Mission Radar (MMR) and its latest evolution, the Multi‑Sensor MMR (MS-MMR).
The consortium, known as G2E, is formed of four leading national defence electronics companies: Mitsubishi for Japan, Leonardo UK for the UK and both Leonardo and ELT Group for Italy.
The uncrewed aerial vehicles (UAVs) will start off in the electronic warfare space, according to the companies, to support existing crewed frontline platforms, with many major details still to be disclosed.
The British-built long-range strike one-way effector (OWE) is the latest offering from the company, which demonstrated its smaller OWE SkyShark in July.
