In a major boost to India’s air defence, the Surya Very High Frequency (VHF) radar was reportedly delivered to the Indian Air Force (IAF). The Surya VHF is an indigenous system designed to detect stealth aircraft, reported The Economic Times. It was developed by Bengaluru-based Alpha Design Technologies Limited (ADTL).
The first of the six units was delivered to the IAF in mid-March 2025 under a ₹200 crore contract, according to reports.
Key Features of Surya VHF:
- Anti-Stealth Capabilities: The radar uses longer wavelengths, which reportedly allows it to detect stealth objects by minimizing the effects of radar-absorbing materials.
- It has a detection range of 360 kilometers for a target with a radar cross-section of 2 square meters, according to The Economic Times.
- The radar is mounted on two 6×6 vehicles and performs 10 rotations per minute.

The deployment of the Surya VHF radar enhances India’s multi-layered air defense network. Its reported induction comes amid speculation that China may provide the advanced fifth-generation stealth fighter jet J-35 to Pakistan later this year.
India’s air defence system received global appreciation during Operation Sindoor, launched by the Indian Armed Forces to avenge the Pahalgam terror attack in April this year. India carried out precision strikes on nine terror camps in Pakistan and Pakistan-Occupied Kashmir (PoK) on the intervening night of May 6 and 7.
In retaliation, Pakistan launched drone and missile attacks targeting both civilian and military installations. However, India’s air defence systems successfully thwarted the attack.
On the intervening night of May 9 and 10, India responded by striking 11 Pakistani air bases, inflicting heavy damage. On the afternoon of May 10, Pakistan’s Director General of Military Operations (DGMO) contacted his Indian counterpart and urged a ceasefire.
