The Pentagon’s focus on laser weapons signifies a strategic shift in military operations. These weapons are advancing from laboratory experiments to real-world applications. Tom Karako, a specialist in missile defense at the Center for Strategic and International Studies, outlines recent developments, the capabilities of lasers, and their limitations compared to traditional missiles.
For many years, the Pentagon sought to develop laser weapons promising rapid response to threats like drones and missiles without the high costs associated with interceptors. Now, after extensive testing and revisions, the Army seems ready to make significant progress. The Army is close to awarding a contract for an enduring high energy laser (E-HEL), a system positioned as the first laser weapon to achieve lasting operational capacity.
This move comes amid evolving warfare tactics where inexpensive drones outmatch traditional air defenses. They compel military forces to use expensive missile interceptors. If successfully deployed, this energy laser system could offer the U.S. military a novel method to counter such threats, reducing reliance on costly kinetic weaponry.
“It’s not about the laser anymore,” remarks Tom Karako. “It’s about ensuring the system functions effectively in various conditions, including dust and heat.”
The Pentagon is concentrating on integrating these weapons into operations effectively. This involves ensuring lasers can operate in diverse environments and developing operational protocols. Unlike missiles, lasers function primarily as line-of-sight weapons, limiting their range to visible targets. This characteristic means lasers will augment, not replace, existing missile defenses.
As lasers become more operational, they will form another layer in the Pentagon’s defensive strategies. Missiles will remain essential for targeting threats beyond visible distances and under challenging conditions. Lasers, effective against nearby aerial threats, will serve as part of a multi-layered defense system.
Concurrently, the Army is developing next-generation counter-drone missiles, aiming to reduce costs per interceptor. These efforts are part of a strategy to offer cost-effective solutions against unmanned aircraft.
In addition to lasers, the Pentagon explores other directed-energy technologies. High-powered microwave systems, such as Epirus’ Leonidas, counter swarms of drones by emitting electromagnetic bursts that disrupt their electronics. Radio-frequency technologies are also under evaluation to jam drone communications with operators or hinder navigation signals, potentially neutralizing aerial threats.
