**ISLAMABAD:** Pakistan has activated a new suite of indigenous active electronically scanned array (AESA) radars, marking a significant step toward greater self-reliance in air surveillance and defence capabilities.

The development includes the long-range AM-350S, the mobile Machaan Ground Radar for Air Defence (GRAD), and the short-range SR-3D system. These platforms form a layered, networked architecture developed primarily through the National Aerospace Science and Technology Park (NASTP), Global Industrial Defence Solutions (GIDS), and the National Radio Telecommunication Corporation (NRTC).

Defence officials describe the deployment as a shift from reliance on legacy imported systems to domestically produced sensors with enhanced mobility and electronic counter-countermeasure (ECCM) features. The systems integrate with existing China-backed satellite data links to support network-centric operations.

The AM-350S, unveiled in November 2024, serves as the strategic early-warning component. Jointly developed by NRTC and Blue Surge, it is an S-band GaN-based AESA radar with a claimed maximum detection range of 350 kilometres and altitude coverage up to 60,000 feet. It provides 360-degree azimuth scan with mechanical rotation at 6 RPM.

The Machaan GRAD addresses tactical and low-to-medium altitude threats. Developed by GIDS, this mobile S-band 3D phased array radar offers approximately 100 km detection range against 1m² RCS targets and supports rapid relocation to enhance survivability.

The SR-3D, introduced by NASTP in March 2024 at IDEAS-2024, functions as both surveillance and target acquisition radar. It operates at 30 RPM for a 2-second refresh rate, with an 80 km range suited for terminal engagement zones.

These systems replace or supplement older platforms such as the Siemens MPDR series from the 1980s, US-supplied AN/TPS-77, and various Chinese YLC-family radars. Legacy static emitters had become vulnerable to Suppression of Enemy Air Defences (SEAD) tactics, as demonstrated in regional operational analyses.

A senior defence source familiar with the programme stated that indigenous production reduces supply chain risks and end-user restrictions associated with imported high-end electronics. Pakistan had previously relied on external sources for up to a significant portion of its advanced defence inventory.

The National Aerospace Science and Technology Park, inaugurated in 2023, served as a key incubator. It consolidated radar and sensor research while collaborating with Turkish and local entities on related projects. GIDS contributed expertise from its work on fire-control systems and UAVs.

**Key Technical Parameters**

– **AM-350S**: S-band, >400W output, GaN TRMs, digital beamforming, elevation scan -6° to +20°, intra-pulse frequency agility for ECCM.

– **Machaan GRAD**: Mobile deployment on TEL vehicles, velocity tracking from 25 to 2500 knots without blind speeds, built-in IFF and north-finding sensors.

– **SR-3D**: Rapid 30 RPM scan, optimised for low-RCS targets including UAVs and stealth features in terminal airspace. A longer-range variant targeting 160 km is under development for late 2026.

These radars use Gallium Nitride technology, which provides higher power density, better thermal performance, and smaller footprints compared to older GaAs modules. This enables stronger signals and improved resistance to jamming.

Pakistan’s air defence modernisation followed lessons from past regional tensions, where static radar locations were reportedly mapped and targeted. The new emphasis on mobility follows a “radiate-and-relocate” doctrine to counter precision strikes and electronic warfare.

Integration via satellite data links allows machine-to-machine sharing of the Recognised Air Picture. A detection by one node can cue interceptors or other sensors across the network, reducing reaction times from minutes to seconds.

Regional analysts note that while the systems do not fully close numerical asymmetries in combat aircraft, they raise the cost and complexity of stand-off strikes by contesting the electromagnetic spectrum more effectively.

Market and industrial implications include potential export opportunities for these radars and related technologies. The developments also strengthen Pakistan’s position in joint exercises and defence diplomacy with partners.

The programme reflects a broader push for defence indigenisation. Earlier efforts included local upgrades of MPDR radars in 2019, which built institutional expertise before transitioning to clean-sheet designs around 2020.

Defence planners aim to create overlapping coverage: strategic depth from AM-350S, tactical mobility from Machaan, and terminal precision from SR-3D within the Short Range Air Defence (SRAD) layer that includes systems like FM-90 and emerging directed energy options.

Challenges remain, including full operational integration, training, and maintaining the network under contested conditions. Reliance on allied satellite infrastructure introduces a layer of external dependency despite sensor sovereignty gains.

Future developments are expected to include expanded production, further ECCM enhancements, and potential airborne or naval variants. Officials have indicated continued investment in sensor fusion and data link resilience.

The activation of this radar triad signals Pakistan’s intent to maintain a credible air defence posture through technological adaptation rather than platform quantity alone. As South Asia’s security environment evolves, such networked sensor capabilities will likely influence operational planning across the region.

Ongoing evaluation and iterative improvements will determine long-term effectiveness against evolving threats including advanced stealth platforms, saturation drone attacks, and sophisticated electronic warfare suites.
