Israel’s Elbit Systems has revealed that it has been contracted to develop aircraft-mountable versions of its XCalibur high-power laser systems. Primarily intended for use on jets and helicopters, the idea is to provide low-cost per-shot solutions for threats such as drones and missiles.

This will overcome the main challenge of firing expensive missile interceptors to knock out these threats; the economics don’t add up. Add a few cents per shot, if a laser beam can be used instead of a $40,000 and $100,000 Tamir missile (those used in Israel’s Iron Dome), then interception becomes far less costly.

Especially when the incoming targets cost a fraction of this. If interception costs can be dramatically reduced (perhaps even cheaper than the target), then the economics of such an engagement could be flipped on its head, i.e., drones become the expensive element, not the interceptors.

This news came to light when Elbit’s President and CEO, Bezhalel Machlis, disclosed the deal during the company’s end-of-year results to shareholders. He announced that the deal was agreed in late 2025, which will aim to deliver a pod-type setup for jets and a helicopter variant called “Sting.”

“The advantage of the aerial laser is that it is less affected by humidity, rain, dust, and atmospheric conditions the higher you go,” Machlis told shareholders. This means that these systems will be able to operate above the clouds, for instance.

It should also mean that the system should be able to strike threats before they arrive because it can see them from the air. ” This would also be a game-changer as conventional air defense systems, like the Iron Dome, can suffer due to bad weather, line-of-sight blocking from terrain, and shorter engagement range due to ground location.

Having lasers on aircraft means you can operate above cloud level, identify and track targets earlier, and engage them sooner.

However, there are still many technical challenges to overcome before such a system can become viable for aircraft mounting; namely, cooling and size. “You need to miniaturize the elements,” Machlis added. “While moving, you need to lock yourself on a target and in a very precise way,” he explained. High-energy lasers also generate a lot of heat, which needs to be managed for obvious reasons. This typically requires a lot of cooling gear, and space is at a premium on aircraft.

Many challenges to overcome

To this end, any aircraft variant will need to have some form of compact generators and cooling systems. Having such a system on aircraft also introduces other issues, like tracking and stabilization, when the target is small and both the target and interceptor are moving.

Any solution will need ultra-precise tracking systems and adaptive optics to correct beam distortion.

But, Machlis is confident that Elbit can “overcome all these challenges,” and after “advancing with large investment, they will be operational with the air force, and I think there is a big market for this worldwide,” he added.

“I also want to add that [the] high-power laser is not just a defensive weapon. As you can understand, it has more applications,” Machlis said. As Breaking Defense points out, it is not entirely clear what he meant by this comment.
