Turkish defense manufacturer Roketsan is integrating its upgraded Alka laser weapon system into Türkiye's Steel Dome multi-layered air defense architecture as the directed-energy component. The system has been scaled from 2.5 kW to over 10 kW, enabling both soft-kill and hard-kill operations against evolving drone threats, including wired variants resistant to jamming. Alka incorporates artificial intelligence to reduce detection and response times, and uses advanced radar to detect and prioritize faster, more sophisticated targets. Roketsan's weapons director Koray Dayanc confirmed the system is already operational and that efforts to further increase laser energy capacity are ongoing. The development reflects a global shift toward directed-energy weapons as cost-effective drone countermeasures, with Roketsan positioning Alka to serve as the final hard-kill layer of the Steel Dome system.

The agreement strengthens Turkey's role as an energy hub and supports European energy security through diversified routes, including Azerbaijani gas via TANAP and TAP.
