Pakistan Air Force-led radar development is now moving beyond broad claims and into clearly defined systems and capabilities. Official material from the National Aerospace Science and Technology Park (NASTP) points to named platforms, including indigenous AESA-based radars and short-range systems like the SR-3D, along with more advanced variants under development.
Ongoing work in areas like AESA radar, sensor fusion, and electronic warfare highlights deeper integration between platforms, data links, and weapons systems. This signals a broader move toward self-reliance and a more mature radar ecosystem built around indigenous research, procurement, and specialized technical development.
NASTP’s radar work is now easier to see
NASTP’s official website describes the project as a Government-approved project of strategic national importance led by the Pakistan Air Force. Its NASTP Alpha profile says the site hosts the PAF’s largest organic design and R&D setups in radar, wireless, and communications systems. That matters because it shows radar work is not a side activity. It is part of the park’s core mission.
The biggest change since the original article is that NASTP now publicly names more of the radar and sensor work. Its official Sensors Division page says the division is leading the indigenization of radar and sensor technology and is advancing next-generation work across HF, L, S, and X bands. The same page says the division has already delivered breakthroughs including an S-band radar for defense, HF and L-band radar for commercial use, and an indigenously developed IFF module.
Named systems have replaced vague references
Passive surveillance and SRAD
NASTP now publicly identifies a Passive Surveillance System (PSS) that detects RF emissions from radars, aircraft, and drones to give early warning without relying on active emission. It says the system works on the Time Difference of Arrival principle and is built to localize and identify emitters across wide areas and long ranges.

The same page also names SRAD, a medium-range S-band radar now under development. NASTP says SRAD is designed for dual use as both a surveillance radar and an acquisition radar for surface-to-air missile systems. It also says the design uses AESA technology and digital beamforming, which gives the program a clearer technical identity than the original article ever did.
IFF and radar upgrades
NASTP also says it is developing two ground-based IFF interrogator variants: a short-to-medium-range 150 km version and a long-range 450 km version. That shows the work is not limited to radar antennas alone. It also includes the identification layer needed for modern air-defense networks.
Just as important, NASTP’s current official wording updates the radar-upgrade story. The February 2025 article said the organization had upgraded over 40 radars. NASTP now says more than 45 upgraded radars from six different origins have been operational since 2017. That makes the current version of the story more specific and more credible.
Procurement and hiring show continued momentum
The radar story has also moved into visible execution work. On January 6, 2026, ACPPL-NASTP issued a formal tender for Procurement of RF & Misc Items, with documents available at Sensors Division, A3, NASTP Rawalpindi. That is a concrete public sign that the sensor program is buying hardware, not only presenting ideas.
Hiring activity points the same way. Late-2025 and early-2026 job postings show NASTP recruiting across RF & Microwave, Antenna Design, Test & Qualification, Embedded Systems, and Sensors Division roles. Several listings specifically mention radar, EW, phased arrays, direction-finding receivers, EMI/EMC, and field trials. NASTP’s current home page also continues to list active RF/MW and DSP roles.
Why the radar push matters
The wider military context also changed in 2025. On May 12, 2025, Air Vice Marshal Aurangzeb Ahmed said Pakistan’s air-defence network was equipped with advanced radar systems and ISR technology optimized to detect stealthy, low-RCS, high-speed, and slow-speed threats. That statement did not name NASTP projects directly, but it showed why indigenous radar and sensor work has become so important to the PAF.
