MoD signs Rs 811 crore contract with BDL for 160 Satellite Smart Anti Airfield Weapons for IAF. Indigenously designed and developed by DRDO, the system will have an indigenous content of 60% along with indigenous of sub-systems like Initial Measurement Unit, Long Impact Delay Fuse and Twin Store Carrier to further boost Aatmanirbharta in defence.

The delivery of SAT-SAAW is scheduled between 2027-2028 and 2028-2029. 

SAT-SAAW is not an entirely new weapon separate from SAAW. It is the satellite-guided configuration of the DRDO-developed Smart Anti-Airfield Weapon (SAAW) family.

SAAW has been developed with different guidance configurations, including satellite navigation and electro-optical/IIR-based guidance. The newly contracted SAT-SAAW specifically refers to the satellite-guided variant.
So, while the overall weapon family and role remain broadly the same, the key difference is the guidance configuration used for precision targeting.
