The IAF has reportedly cleared specifications of an improved Tejas LCA - termed Standard of Preparation-2018 (SoP-18) - with a view to ordering around 100 LCAs built to this standard. A key capability of the new SoP-18, will be incorporation of an Israeli AESA radar, "to be jointly developed with India." The Tejas is currently equipped with the Elta EL/M-2032 mechanically scanned radar, while the new AESA is to be based on the company's EL/M-2052 electronically scanned offering. Earlier, HAL Chairman T Suvarna Raju had stated that the IAF's Jaguar DARIN III upgrade would include fitment of the EL/M-2052 radar, and hinted that other aircraft in the Air Force inventory, such as the Mirage 2000, may eventually receive the radar as well. Other aspects of the SoP-18 Tejas are air-to-air refuelling, a podded self-protection jammer (SPJ) and "improved maintainability."
