There is no doubt that lasers will play a bigger and bigger role in combat systems, especially in a layered air defense networks.
But it’s dishonest how these articles only cite the cost of electricity. It would be like citing the cost of a single shell of artillery to imply that is the only expenditure when the system is used.
Just like a Howitzer, the parts on lasers experience wear and tear, but to replace them cost a hell of a lot more than a new barrel.
Yes, in the long-term lasers will be more cost-effective than ground to air missile interceptors*, but any reporting that is clearly trying to make an argument for cost savings, should have the integrity to get figures that factor in battlefield maintenance of those systems.
*When applicable. Lasers will not remove the need for any existing systems, but will provide a cost savings by providing additional options for the air defense system’s operators.
