The Defence Research and Development Organisation (DRDO) has partnered with Adani Defence and Aerospace to manufacture its Drone Detect, Deter, and Destroy (D4) counter-unmanned aircraft system (C-UAS), a company official told Janes at the Aero India 2023 show, which was held in Bangalore from 13 to 17 February.

The technology transfer has been completed, and Adani has started manufacturing the D4 C-UAS, the official said.

The D4 C-UAS has been demonstrated to various services and security agencies under the Ministry of Defence (MoD) and the Ministry of Home Affairs (MHA), the official added. Janes understands that the DRDO and Adani have secured contracts from these agencies/services.

The C-UAS has also been deployed at various government events involving top-level dignitaries, the official said.

The D4 C-UAS has automatic detection, classification, and neutralisation capabilities both at day and night. It can also be operated manually.

The system can be operated in a stationary mode as well as from mobile vehicles. It is also portable.

The D4 C-UAS includes an X-band radar, with a detection range of 4 km for micro unmanned aerial vehicles (UAVs). The radar has an azimuth coverage of 360°, and an elevation coverage of 50°.

The C-UAS can detect radio frequencies of UAVs – operating at 400–6,000 MHz – up to a range of about 3 km.

The electro-optical/infrared (EO/IR) system of the C-UAS has a detection range of up to 3 km. It comprises a laser rangefinder (LRF), and is available in both cooled and uncooled configurations.
