This is what Iran hit with 300 kg of explosive missile this morning: a highly sensitive target. 
Aviv (“Av‑Kam”) Research Centre – Israel’s Hidden Technological Hub: 700 personnel
The Aviv or Av‑Kam Research Centre, situated in the Negev Desert near the Dimona nuclear complex, represents one of Israel’s most secretive military-industrial facilities. Although its exact functions are shrouded in official silence, open-source experts and satellite analysts attribute sophisticated roles to the centre:
Close to the Shimon Peres Negev Nuclear Research Center, the site lies within Israel’s broader high-security enclave, protected by multiple concentric perimeters.
Analysts believe Aviv supports research and development in radar, sensor arrays, electronic countermeasures, and command-and-control systems—essential components of Israel’s multi-layered missile defence networks, including Iron Dome, David’s Sling, and Arrow .
Missile and nuclear links: Its proximity to nuclear facilities and defence nodes has led to speculation about roles in nuclear command, early-warning systems, and even clandestine nuclear-related R&D—consistent with Israel's policy of "strategic ambiguity" .
The centre likely forms part of a broader tech ecosystem spanning the Negev: it may work in concert with the Israeli Defense Forces' cyber warfare units (e.g. recently relocated to Be'er al-Sabe') and high-tech parks like Gav-Yam and Ben-Gurion University’s tech campus.
Like the Dimona reactor, Aviv is neither officially acknowledged nor described in budgetary releases.
